Comment by Tom Davey

Mr. Harper, the climate change alarm bell sounded in Canada over 40 years ago

aving first reported on climate change in 1968, I was disconcerted to see how badly Canada is now fairing on the world stage. In their article, entitled “Copenhagen and beyond – making the transition to a low-carbon economy” (See page 60), Ted Dhillon and Dr. Bernard Fleet report that “in Copenhagen, Canada was widely viewed as a laggard in its commitment to the environment. Previously, the Harper government had stressed its intention of integrating our climate change policy with that of the US. It is now clear that the reverse is taking place, and there is a widening gap between President Obama’s clean energy agenda and Canada’s continued support for the oil sands.” They go on to say that “Canada has already earned a failing grade in the GHG stakes. Failing to meet its modest reduction targets, its environmental reputation was further tarnished during the recent conference in Bangkok, a precurwww.esemag.com

sor to Copenhagen. Canada’s proposal to cherry pick parts of Kyoto for incorporation in the new COP15 agreement was greeted with outrage and a mass walkout by representatives of the Group of 77 developing nations.” Sadly, achieving consensus on what can – and should be done – about climate change is proving to be as difficult as I predicted it might be, back in 1968. The science and economics are complicated. Political will is often too focused on the here and now. As he has prorogued Parliament twice now, to thwart the opposition, perhaps Prime Minister Harper thinks that ignoring climate change will make it go away as well. Future generations, coping with a climate different from what we now know, might ask their great-grandparents: “Did they not know?” Well, for the historical record, we did know that something was going on, as you will see in the reprinting of my October 1968 Editorial Comment…..Tom Davey

hile scientific knowledge is increasing at a pace unthinkable a generation ago, there is a startling lack of correlated data on the environmental effects of air pollution. Years ago, Aldous Huxley said Man was squandering natural resources with the gay abandon of a sailor on a drunken weekend spree. We may yet be grateful that some resources – such as fossil fuels – are irreplaceable. Atmospheric carbon dioxide has risen approximately 14% in little over a century, with some ecologists speculating that oxygen regeneration is being reduced at a disastrous rate. But scientists, almost literally, wax hot and cold on fundamental points. Some say continued increases in carbon dioxide will prevent heat from rising into space, to a point where polar ice caps will melt. This would cause massive flooding, with subsequent shrinkage of surface land. More recent trends foresee a colder earth, based on theories that air borne pollutants will increasingly block out the sun. But although statistical evidence is damning, conclusive proof of how air pollution affects health is generally not forthcoming, in spite of unprecedented research. For scientists attempt a burden of proof far beyond that which their legal colleagues would accept as reasonable circumstantial evidence. Additionally, the problem is compounded because it concerns the total environment, with meteorology, medicine, chemistry, engineering, and other disciplines playing significant, but largely separate, roles. Meanwhile, in North America alone, almost 100 million motor vehicles emit approximately 250,000 tons of carbon monoxide and other lethal gases every day. The daily continental sulphur dioxide fallout from industry greatly exceeds 100,000 tons. It has been shown that sulphur dioxide concentrations of one to two continued overleaf... January 2010 | 7

parts per million – just below the threshold of odour detection – decreases human ability to inhale and exhale. But some scientists believe that other contaminants, acting singly or together, are of greater significance as pulmonary irritants. There is widely based evidence that lung cancer mortality rates are from two to four times higher in urban areas than those found in rural districts. But again, there are too many variables to specifically indict particular contaminants as yet. Ultimately, there is no escape – wind borne contaminants are now even reaching the Polar Regions. And when Afro-Asia’s teeming millions achieve industrialization, the threat of intolerable contamination becomes more than mere conjecture. Eight hundred million Chinese could create a fair pollution problem merely by striking matches. What happens if they emulate the West and start driving eight cylinder autos? 1 If this seems remote, remember Japan transformed from a primitive agrarian economy, to a sophisticated industrial nation, in little over two decades.

Letter to Editor Re: “Preferred status should not mean status quo” ES&E, Nov/Dec’09 issue Dear Steve: Thank you for succinctly identifying a chronic problem in many jurisdictions throughout North America and a practical way to engage stakeholders (consumers, provincial and/or state governments, engineers and technology suppliers) to arrive at a solution.

ronmental study facilities where scientists can research in teams, instead of the present fragmented faculty programs. Another is the belated awareness, at all levels of government that air pollutants roam freely over their puny boundaries. While jurisdictional squabbling has delayed implementation of watershed controls, meteorologists are already talking of “air sheds” in attempts to master temperature inversions, which prevent effective pollutant dispersal. Economics and history have channeled our creative energies into incredibly sophisticated production techniques, with pollution control subordinate to profit. Unless this order of priorities is reversed, the ecological consequences will exact a heavy toll in the near future. Stringent government controls and enforcement, tax incentives for anti-pollution devices, along with more coordinated research – these are the basic requisites for tackling the problem. More important, perhaps, is public awareness of how rapidly the problem is accelerating. Otherwise we may be forced into a mode of living epitomized by Buckminster Fuller’s geodesic dome at the post Expo ’67 show, “Man and His World”. There, fairgoers vicariously enjoyed fountains, trees and a bird sanctuary amid the great indoors, now significantly renamed the Biosphere. Expo’67 was a culmination of man’s cultural and manufacturing achievements. Perhaps the Biosphere symbolizes the future protection he will need from the residual effects of his productive genius as he increasingly moves towards the ultimate synthesis. 1

Asian carp threatening the Great Lakes According to the environmental group, Great Lakes United, one heavy rainfall could allow Asian carp to breach the electric barrier in place in the Chicago Sanitary and Ship Canal (CSSC), which prevents fish from spreading into the Great Lakes. Recently discovered just a mile from the barrier, carp have also been found in the Des Plaines River, which is less than 100 feet from the canal in some places. The fear is that during a flood event, carp in the Des Plaines River could bypass the CSSC’s electric barrier completely. “If Asian carp make it into Lake Michigan, they won’t stop at the border,” says Dr. Terry Quinney from the Ontario Federation of Anglers and Hunters. “They will invade all of the Great Lakes, and could spread within inland waterways across the province. This will affect the $7 billion dollar recreational and

commercial fishery, as well as degrade biodiversity.” Suggested measures to stop the spread of invasive species include: • Fill in critical sections of the Illinois & Michigan Canal, so that the carp cannot swim into the CSSC during floods. • Create an emergency physical barrier (like sandbags) between the Des Plaines River and the CSSC, to ensure the Des Plaines River and live carp cannot flood into the CSSC, and by pass the electrical barrier. • Install an additional barrier (such as a bubble/acoustic barrier) to stop carp from migrating upstream into the Des Plaines River. www.glu.org

Aquatic Life Research Facility opened at CCIW The new Aquatic Life Research Facility at the Canada Centre for Inland Waters (CCIW) in Burlington, Ontario, is a $4.6 million state-of-the-art laboratory, designed for studying the health of fish, and other aquatic life, exposed to potential

environmental stressors. Built as a joint project between Environment Canada and Fisheries and Oceans Canada, it provides space for scientists, graduate students, and university partners. To ensure the efficient use of water and energy, it will employ the latest water recirculation technology. Facility scientists will be studying various aquatic health issues more effectively, including: • effects of contaminants, such as chemical and biological stressors, on aquatic life. • impacts of changes to the food chain, water quality and temperature. • effects of aquatic invasive species on other aquatic life. • study of native species and their life cycle, including species at risk. These studies will help the Government of Canada to meet its commitments under the Fisheries Act, the Canadian Environmental Protection Act, 1999, the Great Lakes Water Quality Agreement, the Species at Risk Act, and other freshwater policies and regulations. continued overleaf...

WFP donations surpass benchmark For the second year in a row, donors to Water For People partnered with philanthropists, Stephen and Sandy Rosenthal, with the goal to raise $1 million, and once again surpassed the benchmark in support of improved sanitation, safe drinking water solutions, and hygiene education in developing countries. For the last two years, the Rosenthal Family has contributed $500,000, with the goal of leveraging their gift. The family challenged Water For People donors to match their gift dollar for dollar and raise $1 million in support of its programs around the world. This year, over 823 donors responded to the challenge and donated more than $798,000, totaling $1,298,735 within two months. www.waterforpeople.org

ing through the federal Networks of Centres of Excellence program, to bring together multi-disciplinary teams of energy, environmental and social science researchers at Canadian universities. They will work with partners in industry, government, NGOs, and carbon management networks around the world, to develop insights, technologies and policies needed to greatly reduce globalwarming carbon emissions in Canada’s fossil energy sector. The network is expected to help reduce carbon emissions by 80 per cent or more by 2050, compared with projected emissions under a “business-as-usual” scenario. www.carbonmanagementcanada.ca

Professional Engineers Ontario (PEO) has said that it approves of action taken by the federal government to enhance foreign qualification recognition for internationally-trained workers. Under a new framework released recently by the Federal Minister of Human Resources and Skills Development, foreign-trained professionals, including engineers, will be told within one year of application whether their qualifications will be recognized for licensure. In May 2007, PEO introduced the Engineering Intern Training Financial Credit Program to encourage engineering graduates and newcomers to Canada to apply for licensure. The program enables eligible graduates of undergraduate Canadian engineering programs and eligible international engineering graduates with a bachelor of engineering or a bachelor of applied science degree to apply for a professional engineer licence at no cost. They may also be eligible to register in the Engineering Intern Training program for the first year at no cost. www.peo.on.ca

Northern Gateway Pipeline. “The process the federal government has selected for considering this project turns a blind eye to the climate impacts of tar sands expansion,” said Nikki Skuce, an energy campaigner with ForestEthics. “This is a review process that has historically approved 99% of the projects it has considered.” If approved, the proposed Pipeline would allow a 40% expansion of Alberta's tar sands, which could increase GHG emissions from the region dramatically. The project would also expose interior salmon rivers and coastal marine environments to the risk of oil spills, according to the group. Given the narrow scope and concerns about the Canadian Environmental Assessment Agency/National Energy Board process, a number of municipalities and local governments in the affected region have called for a Public Inquiry. www.forestethics.ca

BP Energy fined for vapour discharge BP Canada Energy Company has pleaded guilty to one count of causing an odorous discharge that caused, or was likely to cause an adverse effect. In Sarnia, Ontario, the company operates a natural gas liquid fractionation plant, which produces propane, butane, isobutane and production condensate. In March 2009, during functionality testing of the facility’s valves, a vapour plume, lasting approximately ten min-

utes, travelled offsite in a northerly direction. Some Sarnia residents reported experiencing temporary physical symptoms as a result of the odour, such as headaches, sore throats and nausea. The discharge also caused disruptions to schools and businesses. BP Canada Energy was fined $800,000.

Tracking and reporting program now in effect Beginning January 1, 2010, regulated Ontario-based facilities in the manufacturing and minerals processing sectors are required to track, report and develop plans to reduce the toxic substances they use, create and release. This applies only to facilities currently reporting on emissions to the National Pollutant Release Inventory. Ontario has also committed funding to help facilities meet the requirements of the Toxics Reduction Act. The government will hold province-wide information sessions to explain the new requirements. It will also provide information guides to help facilities meet the requirements and will consult on an enhanced toxics reduction planning process that builds on the expertise and experience found in the workplace. The first reports from facilities covering the 2010 calendar year are due by June 1, 2011, and summaries of the first toxics reduction plans are due by the end of 2011. The first reporting requirements cover 47 priority substances.

Manitoba and South Australia sign MOU During the recent Climate Change Summit in Copenhagen, Manitoba Premier Greg Selinger and South Australian Premier Mike Rann announced an agreement for renewed cooperation on climatechange adaptation and water-resources management priorities that are important to both Manitoba and South Australia. The memorandum of understanding provides a general framework to work together and share expertise on: reducing flood hazards; developing strategies to cope with long-term droughts; and community capacity building and ecological goods and services programming to provide resilience to future climate-change challenges. Manitoba and South Australia share a history of collaboration on economic and social priorities and signed an MOU in 2006 to strengthen their respective biological and life sciences sectors and ensure further collaboration in biotechnology, renewable energy, sustainable development, climate change, and Aboriginal economic development.

of any pollutant that may cause, is causing or has caused an adverse effect on the environment. Additionally, greenhouse gas emissions from a proposed project must now be considered before a licence is issued. The Act also provides environment officers with expanded powers to intervene in a situation before the environment is impacted. The strengthened Environment Act builds on the province’s enhanced inspection programs, which focused initially on the north Red River corridor. The program is designed to inspect wastewater systems on residential properties in sensitive areas to ensure the environment is being protected.

Saskatchewan adopts new regulations On November 30, 2009, Saskatchewan’s Environment Minister Nancy Heppner introduced a proposed new act and amendments to two others. The Environmental Management and Protection Act, 2009, along with amendments to The Environmental Assessment Act and The Forest Resources Management Act, set the

14 | January 2010

stage for the adoption of a results-based environmental regulatory framework for Saskatchewan. The current regulatory regime was developed in the early to mid-1970s to address industrial point source pollution and unregulated resource harvesting. The regulatory toolkit consisted almost entirely of prescriptive legislation and regulations that directed agency inspections and enforcement when contraventions were identified. The Saskatchewan Ministry of Environment will soon move forward on a number of other initiatives, including: • Developing a Saskatchewan Environmental Code that will provide for standards and practices that will set the framework for improved environmental management; • Reorganizing the ministry to better deliver the requirements of results-based regulation; • Providing an electronic platform for environmental information and program delivery, including web-based environmental applications, compliance and reporting. This will facilitate a streamlined application process and transparency in the min-

istry's reporting and collaborative decision-making processes; • Continuing to engage the public and stakeholders in consultation as the design and implementation of the new regulatory framework are developed.

Information now available online The website SaskH2O.ca now offers details on local wastewater treatment throughout Saskatchewan. In addition to finding out if a community has been issued any warnings about the quality of drinking water, one can also find information on wastewater treatment, such as when the last inspection was conducted, what was the outcome, and how to contact the facility operator. The information will be of interest to a wide variety of groups, from local residents to businesses, engineers and municipalities. SaskH2O.ca brings together information and services available from the Government of Saskatchewan that relate to water, regardless of the ministry or agency that produces the information or offers the service.

Action plan guides Alberta's water management Alberta Environment Minister, Rob Renner, speaking about the renewed Water for Life action plan.

Healthy aquatic ecosystems, conservation, and education, are priorities in the renewed Water for Life action plan, which lays out the actions Alberta intends to deliver over the next decade. It includes activities Alberta committed to deliver as part of its original Water for Life strategy and incorporates new actions to address the province’s emerging water challenges and current realities. The action plan also supports regional environmental objectives and Alberta’s cumulative effects management approach. The Alberta Water Council’s 2006-08 implementation review acknowledged that Water for Life implementation is making good progress. The Council identified the need to: integrate and coordinate the management of land, water, air, biodiversity, and the cumulative impacts of development; ensure partners

have the funds and people needed to complete their work; and encourage Water for Life leaders and champions. They also made recommendations to increase focus on education and protect Alberta’s rivers, lakes and aquifers from overuse and contamination. www.waterforlife.alberta.ca

WERF to evaluate technologies that address aging infrastructure The Water Environment Research Foundation (WERF) will receive $10 million from the US EPA to evaluate new technologies designed to help utilities cope with aging and failing water and wastewater systems. $6.25 million will address wastewater and stormwater infrastructure, and $3.75 million will address aging drinking water systems. These funds will be further leveraged by a 33.3% cost share to be provided by the investigators. Funding for the research is through EPA’s Aging Water Infrastructure Research Program, a research agenda that supports efforts to put the nation’s aging infrastructure on a pathway toward sus-

tainability. Research efforts initiated under the cooperative agreement will examine innovative tools and procedures to cost-effectively improve the maintenance, rehabilitation, and replacement of aging sewer lines, watermains, and other components. Research efforts will focus on four key areas: • Condition assessment for water and wastewater conveyance systems. • System rehabilitation for water and wastewater conveyance systems. • Advanced design and engineering concepts. • Innovative treatment technologies for wastewater, stormwater, water reuse, and drinking water. EPA projects a funding gap of $220 billion over the next 20 years if US utilities and municipalities don’t increase their investments in water and wastewater infrastructure. By better pricing and managing water use, as well as by implementing new technologies, that gap may be lessened. www.werf.org continued overleaf...

Teck fined for chemical spill Following an investigation by British Columbia’s Ministry of Environment’s Commercial Environmental Investigation Unit (CEIU), Teck (formerly known as Teck Cominco) was sentenced in provincial court for a chemical spill that took place on May 28, 2008. Teck discharged 900 kilograms of lead refinery electrolyte and 360 litres of acid into the Columbia River, following a technical failure at its Trail lead and zinc refinery. The spill occurred when a heat-exchange unit failed, resulting in chemicals spilling down a stormwater drain, which leads into the Columbia River. The release of lead refinery electrolyte took place over a five-hour period.

Commission, in an agreement to protect the Columbia River basin from the spread of destructive zebra and quagga mussels. Zebra and quagga mussels are two freshwater mollusks native to Eastern Europe that were introduced to the Great Lakes in the 1980s. Over the past couple of decades, the invasive molluscs have spread to eastern Canada, the eastern United States and, most recently, the western US. Zebra and quagga mussels are not currently present in BC waters, but they have been found on intercepted trailered boats en route to BC. The spread of zebra and quagga mussels into BC waters would have a severe environmental impact. Both species can completely replace native mussels and cause a collapse of the natural food chain, threatening local fish species, particularly salmon and trout. Industrial, agricultural and recreational uses of infested areas would be affected. A recent survey estimates an impact of $268 million to power plant and drinking water facilities in the eastern US from 1989 to 2004.

NS introduces stronger guidelines for biosolids Nova Scotia has introduced stricter guidelines for the land-application and storage of municipal biosolids; these were developed from recommendations by an independent committee of citizens, facility managers, wastewater researchers, regulators, and representatives from all levels of government. The guidelines are based on the latest biosolids science and research. The Nova Scotia Biosolids Science and Advisory Committee gave its report, entitled Biosolids Management in Nova Scotia: Issues and Recommendations, to the Department of Environment last year. The report contains many recommendations intended to improve the way biosolids are managed and used. The province is implementing all recommendations, many through the guideline revisions.

AWWA encourages Haiti assistance "The American Water Works Association (AWWA) joins the global community in mourning the terrible loss of life in Haiti following a devastating earthquake," said AWWA Interim Executive Director Paula MacIlwaine. "The many calls and emails that have poured into our offices the past two days testify to the goodness and compassion that define our members." Following a disaster of this scale, the rescue and recovery efforts will continue for several weeks. AWWA encourages its members to direct immediate offers of assistance to disaster relief agencies on the ground in Haiti. Monetary donations are most helpful, because the chaos that follows natural disasters makes material donations difficult to manage. Water for People, AWWA’s charity of choice, recommends Catholic Relief Services and Mercy Corps as effective agencies to receive Haiti disaster relief donations. "As a water community, we are all keenly aware of the water-related crises

The threat of waterborne disease may persist as the emergency response concludes and the reconstruction effort begins. AWWA has received many calls and emails from members offering expertise to help Haitians address water-related issues”, said Ms MacIlwaine.

Ontario is not immune to water shortages

lthough generally considered a water-rich province, Ontario is not immune to drought or serious water shortages. As recently as the summer of 2007 and between the years 1998 through 2002, Ontario experienced some of the worst droughts in its history. It has also begun to experience major changes in weather that diverge significantly from usual climate patterns, and that have produced consequences ranging, even within a single season, from destructive storm events to record-breaking low water events and drought. As a result of global climate change, many experts expect these extreme weather conditions to worsen. The evidence for climate change has continued to mount in recent years, and the leading scientific organization, the Intergovernmental Panel on Climate Change (IPCC), stated in 2007 that “warming of the climate system is unequivocal, as is now evident from observations of increases in global average air and ocean temperatures, widespread melting of snow and ice, and rising global average sea level.” In a 2002 special report, Climate Change – Is the Science Sound?, the Environmental Commissioner of Ontario (ECO) urged Ontario’s leaders to act upon the evidence and take appropriate action to address climate change. Modelling work, published by the Ministry of Natural Resources (MNR) in 2007, predicted that, by mid-century, much of southern Ontario will receive 10 to 20 per cent less precipitation and will experience considerable warming (of two degrees Celsius or more) during the warm season. These changes indicate that the risk of summer droughts will increase over the coming years. The agriculture, forestry and fisheries sectors will face major resource management challenges in adapting to these environmental shifts. Consequences of changes in hydrology During a drought, reduced surface and groundwater source availability is of concern to all, but can expose water dependent industries, including agriculture, horticulture and forestry, to particularly 18 | January 2010

grave financial risk and hardship. For example, a drought that extended across Canada in 2001-2002 was considered a national disaster. Agricultural practices in some parts of the province are already starting to change. Farmers in Essex County, one of the most drought-prone areas, are excavating numerous small storage reservoirs, and in Haldimand and Norfolk Counties, farmers have recently begun irrigating crops over a longer time-span within the growing season. Irrigation systems which are more water efficient, such as drip irrigation, are being devel-

oped and utilized more widely. In addition to effects on industry, drought can have severe impacts on stream ecology. Drought can cause groundwater levels to decline and this, in turn, will cause declines in the flow of groundwater-fed streams. Evaporation combined with water taking from such streams may at some point cause otherwise perennially flowing streams to dry up, with a complete loss of aquatic life. This article examines how the Ontario government has begun to respond to the threat of low water conditions as a growing reality within the spectrum of

Water Supply the hydrologic cycle, and reviews how well the province is equipped to adapt and manage water resources under the conditions of a changing climate. Ontario Low Water Response Plan The changing climate and anticipated stresses on water supply point to the need for strong provincial readiness for managing drought. Drought contingency planning assesses and improves the ability of stakeholders and government to respond to low water conditions in a timely and orderly way. Essential elements of such a plan include: appropriate drought indicators; instruments and policies for water allocation and water supply; methods for public information and involvement; and conflict resolution tools. Numerous significant changes in water quantity management have been implemented in Ontario in recent years. In 2001, following the droughts of 1998 and 1999, the provincial government developed the Ontario Low Water Response (OLWR) Plan to ensure that the province would be ready to assist and support local response efforts in the event of a drought. The program operates with MNR taking a lead role and working in partnership with local stakeholders, and is normally coordinated through local conservation authorities (CAs). The OLWR Plan defines both provincial and municipal government roles in drought contingency management. A key feature of the Plan is the existence of local Water Response Teams (WRTs). The teams include provincial and conservation authority staff, as well as representatives from local water user groups, typically involving the resource management interests of agriculture and other rural private industries, First Nations and municipal government. At the provincial level, key decisions and interactions with WRTs are made by a standing committee known as the Low Water Committee. Planning stages The OLWR Plan establishes three levels of low water conditions that are based on thresholds linked to precipitation records and stream flow monitoring data, together with watershed observations. The OLWR Plan describes these indicators and the thresholds and rules for transition between levels. At Level I, a warning is issued and www.esemag.com

voluntary water conservation measures implemented, and the WRTs are brought together. Level II indicates a more serious problem, bringing about further restrictions on non-essential use. Level III means that water supply is unable to meet local demands. Under this condition, water use restrictions may be established by regulation. Before declaring a Level III condition for a particular area, the WRT is required to have implemented and documented conservation and reduction efforts taken throughout earlier Levels, and demonstrated that the majority of water users have participated; documented and adequately described social, environmental and economic impacts arising from current low water conditions; and provided recommendations on priorities for water use restrictions and other reduction activities within the watershed. Response options The issuing and revising of Permits to Take Water (PTTW) by MOE under the Ontario Water Resources Act (OWRA) is the principal mechanism available to provincial regulators to control takings

of ground and surface water. Most water takings from a surface source or well in excess of 50,000 litres per day require a PTTW. Exceptions are made for water used for domestic purposes, livestock watering and firefighting. Currently, about 6,600 PTTWs province-wide allow permit holders to take a total of about 495 trillion litres of water every year â&#x20AC;&#x201C; an amount equivalent to the approximate volume of Lake Erie. The OWRA affords numerous powers to the MOE Director to restrict water use, and to require studies to support applications to ensure that the quantities being allocated and withdrawn by users promote ecosystem protection and sustainability. During low water conditions, MOE delegates responsibility for determining the relative importance of various water uses to the WRTs. Under the OLWR Plan, water uses are classified as: â&#x20AC;˘ Essential (i.e., uses directly related to human health, such as drinking water, sanitation and fire protection, as well as for basic ecological functions); continued overleaf...

Water Supply • Important (i.e., agricultural, industrial and commercial uses); and • Non-essential (i.e., household uses, such as swimming pools, lawn watering and car washing). Each WRT is responsible for developing strategies to reduce water use during Level I and Level II conditions, targeting a 10 per cent reduction in water use at Level I. At Level II, further restrictions are implemented, including invoking member municipalities’ bylaws for banning non-essential uses. Level III is the most severe condition and, when this level has been declared, the provincial agencies become formally involved in the decision-making process. If and when a Level III condition is declared, the MOE Director can use the OWRA powers to restrict any water taking. A Level III condition has never been declared, although indicator criteria have been frequently met. One of the main problems facing WRTs is the difficulty in obtaining data on actual amounts of water withdrawn by PTTW permit holders. At present, new requirements for monitoring of quantities of water used are being phased in

under the Water Taking Regulation (O. Reg. 387/04). Information on water withdrawals is vital to a WRT trying to determine how water is allocated in a watershed during a drought condition. ECO’s conclusions Climate change, water withdrawals and other forces promise to profoundly affect Ontario’s water environment in the coming years, and will significantly affect urban and rural water users’ ability to consume and their need to conserve water. The ECO is pleased to note a number of recent positive changes to water management policies and practices in Ontario which will aid in adapting to current and future hydrological changes. Water budgets are being developed for most highly utilized watersheds under the Clean Water Act; the monitoring of water quantities taken under PTTWs is now required; and studies are underway on groundwater and surface water interactions which will better inform water permitting. However, the ECO remains concerned that there still are a number of serious gaps in water management practices; when low flow and drought conditions

occur, the OLWR Plan may not function adequately. The voluntary implementation of water use reductions under Level I and Level II requires communication with the public and stakeholders; however, there is generally little ability to monitor the effectiveness of these communications, despite the fact that such an evaluation is required to support a request to the provincial authority for a Level III condition declaration. The ECO is greatly concerned that it seems prohibitively difficult to obtain a Level III condition declaration by the province. The requirements that must be fulfilled by the WRTs, as outlined previously, are too restrictive, in the opinion of the ECO. It is difficult for the WRTs to provide proof of voluntary implementation by “a majority of the water users”. It could conceivably take nearly a month for a WRT to gather and document this information – time during which streams could dry up. The ECO is aware of two streams, one an important coldwater fish habitat, which completely dried up in the summer of 2007, without a Level III condition being declared under the OLWR

out monitoring of water taking rates are also an important tool. Over-allocation in some watersheds nonetheless exists and, when low water conditions occur in these watersheds, restrictions are far more challenging to implement.

Maintaining sufficient water levels and pressures is vital for firefighting.

Water allocation and budgeting The ECO has expressed concern about the over-allocation of water under the PTTW system. Water budgets established in the source water protection planning stage under the Clean Water Act will help inform PTTW decisionmaking and ensure that water is managed through the program in a long-term sustainable manner. Recently introduced requirements that PTTW holders carry

www.esemag.com

As water budgets become available, the ECO recommends that the MOE phase in a PTTW renewal process which is consistent with a watershedâ&#x20AC;&#x2122;s hydrology; recognizes in-stream ecological base flow requirements; and builds in stepwise use reduction criteria that are responsive to low flow level conditions. It may also be worth considering the process used in some American states where all water taking permits for a single watershed

have identical renewal dates. This allows for regionally coordinated planning for water allocation and budgeting. The ECO has also commented in the past on the need for the MOE to develop a clear policy for prioritizing water uses to ensure that PTTWs are allocated in both an ecologically sustainable and socially desirable manner. This is particularly important in view of the increased demands placed on our water resources by a growing population, and at a time when our hydrology appears to be changing. Security of our water resources and the ecological, social and economic systems dependent upon them requires the Ontario government to begin developing water supply priorities and an overall provincial water allocation strategy. The Environmental Commissioner of Ontario is the provinceâ&#x20AC;&#x2122;s independent environmental watchdog. Appointed by the Legislative Assembly, the ECO is tasked with monitoring and reporting on the governmentâ&#x20AC;&#x2122;s compliance with the Environmental Bill of Rights.

Pumps

Pump maintenance is vital, especially during tough times

t is understandable, especially in today’s tough economic times, for pump owners to let a pump run until it fails. Unfortunately, this can cause collateral damage and problems. Ask yourself: What would the consequences of a failure be? Not only could it cause more costly and time-consuming service, but since trash pumps often pump wastewater, this could cause an even bigger problem. Thus, preventive maintenance is a critical part in maximizing a pump’s lifespan, improving cost savings, increasing profitability, increasing pump availability, improving productivity, and decreasing maintenance repair costs. Pumps made by reputable manufacturers are built for the severity of strenuous usage, but all will benefit from regular service and preventive maintenance. Also, the care of trash pumps is reasonably simple. Therefore, it makes sense

for pump owners and pump users to implement a comprehensive preventive service and maintenance program. Effective service and maintenance keeps equipment working at peak efficiency; so service and maintenance

should not be viewed as a strain on income, but rather a contribution to profitability. For the common trash pump, scheduled preventive maintenance generally includes lubrication of seals and bear-

Pumps ings along with oil, fuel and air filter changes every 200 to 250 operating hours, or as recommended by the manufacturer. While this is necessary, it also presents an excellent opportunity to perform an overall pump inspection, especially of wear components, and to make replacements or adjustments as required. This includes adjusting and tuning up equipment and detecting and correcting small problems before they become major problems. Having a manufacturerâ&#x20AC;&#x2122;s trained service technician perform these duties may increase the initial cost of the service when compared to using staff personnel. But, a trained technician will do the job correctly and also discern components which are susceptible to failure, preventing downtime and damage to other parts. This will reduce repair costs throughout the life of the equipment, and result in savings much greater than the initial cost of a service call.

Water Reuse

Conserving water by using a closed loop recycling system By Mark Vogel

or industrial facilities around the globe, water quality and availability have become critical issues. Many engineers assume that, if their facility cannot obtain fresh water, the only available process cooling technology option is a dry cooler. Since low quality water (including blowdown from cooling towers, RO, demin, boiler blowdown, treated wastewater, as well as reclaimed and produced water) can be used as spray water makeup, even those sites with limited water availability have a choice. Closed-loop, evaporative cooling and condensing systems such as Niagara Blower’s Wet Surface Air Cooler (WSAC™) optimize the use of scarce and/or poor quality water resources. A plant can improve or increase capacity by utilizing closed-loop cooling technology without having to purchase additional water or reduce existing fresh water usage. Benefits of closed-loop cooling technology Closed-loop, evaporative cooling and condensing systems are an efficient alternative to dry cooling. The closed-loop system uses evaporative or latent (phase change) heat transfer to remove the process heat, whereas dry coolers use sensible (no phase change) heat transfer. For this reason, the closed-loop process outlet temperatures will approach the design wet bulb temperature while the dry cooler’s process outlet temperature will approach the design dry bulb temperature. There is usually a large difference in these two temperatures; a typical 85ºF dry bulb day at 60% relative humidity would have a corresponding wet bulb temperature of 65ºF, allowing for a much lower process outlet temperature with the closed-loop cooling system. Since the closed-loop system is an evaporative cooling device, it will use as little as one fifth of the plant area required for a dry cooler and require drastically less horsepower to operate. Reduced horsepower leads to lower operating costs, less noise, and a lower carbon footprint. 24 | January 2010

Drenching spray system.

Closed-loop heat transfer surfaces require little or no maintenance. Tubes are all prime surface and do not utilize fins. Furthermore, the closed-loop cooling system uses widely spaced tubular surface coils, which are less prone to fouling and plugging. Water efficiency A closed-loop system rejects heat by evaporation. The process fluid or vapor to be cooled or condensed flows through closed-loop tube bundles. Water from the unit basin is sprayed downward over the tube surfaces while fans induce air flow over the bundles in a co-current direction. On the tube surface exterior, evaporative cooling occurs at the outside water film boundary. The saturated air stream leaving the tube bundle then makes two 90 degree turns into the fan plenum. The reduction in velocity returns most of the large water droplets to the basin. The saturated air is then discharged through the fan stacks at high velocity (1500 fpm). Due to the closed-loop design, wide tube spacing, and high drenching water spray rate, low quality water (even containing suspended solids) can be used as makeup water. Since the open-loop spray water only passes over the tube exterior, it never contaminates the process stream.

A recent study was funded by the Electric Power Research Institute (EPRI) and the US Department of Energy (DOE) to validate water quality limits in a closed-loop, evaporative system. Unit performance using different sources of spray water makeup was monitored and different tube materials (304SS, 316SS, titanium, etc.) were used. The test unit demonstrated that existing cooling tower blowdown could be used in a closedloop, evaporative system running 50+ cycles of concentration with no degradation in thermal performance. Minimizing overall water use There are several design options to consider in order to reduce the overall water use in a process cooling system while still maintaining cooling efficiency: 1. Combining a closed-loop, evaporative system with a dry cooler is one option. In this configuration, the dry cooler can accomplish the first part of the cooling or the highest temperature portion, and the closed-loop system can be used as an efficient trim cooler to finish the remainder of the cooling and achieve the desired process outlet temperature even in the hottest ambient conditions. This cooling combination can attain the low process outlet temperatures that a dry cooler alone would have difficulty

Water Reuse accomplishing. The spray water can be turned off during colder ambient periods to allow the dry cooler to do all the cooling without requiring any water. 2. A wet/dry closed-loop system is another way to minimize water usage. With this design, widely spaced fins (four to five fins per inch) are used on the tube bundle for strictly dry cooling or condensing during colder ambient periods. An optimal ambient temperature is selected, below which the unit can be run completely dry. For instance, the system may operate dry at 80ºF dry bulb or lower and operate in the wet mode with spray water turned on when the ambient dry bulb exceeds 80ºF. This can be either on a seasonal basis or changed from day to night operating modes where dry bulbs may drop below 80ºF. This system still has the advantage of achieving low process outlet temperatures while realizing some of the footprint and operating cost savings of a wet system. Wet/dry systems allow significant water savings while offering operator flexibility in choosing whether to use water, depending on ambient conditions and the plant cooling needs at the time. The importance of customization With a variety of tubing and other materials of construction available, each closed-loop, evaporative cooler or condenser is custom-designed to fit a specific heat transfer application while meeting the customer’s water limitations. To ensure the most efficient operation in all climates, design parameters are based on customer specifications for process inlet and outlet temperatures, weather conditions on an annual basis, and specified water limits. Closed-loop systems can be designed and manufactured with a wide variety of materials depending on water quality, water treatment, and cycles of concentration. Closed-loop coolers and condensers vary in size from small packaged, skidded units to large, field-erected systems. Conclusion Water conservation will continue to be a critical issue. Due to the innovative design and custom manufacturing capabilities, closed-loop, evaporative coolers and condensers can help maintain plant performance while utilizing water streams that may currently be unusable with other cooling technologies. These systems offer many advantages for sites www.esemag.com

with poor quality sources of makeup water, including a reduction of plant fresh water makeup and the ability to reduce plant wastewater.

Stormwater Management

City of Ottawa’s solutions for inflow to combined sewers

he City of Ottawa has older combined sewers in its downtown core and for years has had to find solutions for the undersized sewer pipe system. In 1986, City Council approved the installation of tin covers under catch basins to prevent heavy rainfall events from overtaxing the combined sewer system and thereby causing sewer backups in homes. The tin cover with a small hole opening was simply placed under the cast iron frame on the roadway catch basin (Figures 1 and 2). This product was a maintenance issue for staff and is rarely used anymore. Various devices are available in today’s market for this type of flow restriction for all types of sewer systems. The concept is basically to restrict the amount of water that gets into the catch basins. Products used by the City of Ottawa A similar product is an inlet control device such as a PVC plug placed in the

By Will Curry pipe opening in the catch basin. (Figure 3) This is commonly used for stormwater management practices to restrict water inflow. It is relatively easy to install for existing catch basins or in new residential development areas. It is placed directly in the outlet pipe inside the catch basin. These plug type inlet control devices can achieve a flow restriction in the range of 15 L/s to 50 L/s. However, if the hole is too small, it becomes a maintenance issue and can ultimately block from floatable debris that gets washed into the catch basin from the road. To obtain low flow restrictions a vortex device can be installed in the catch basins. Vortex devices can achieve very low flow restrictions but the City of Ottawa limits the lowest flow control to 6 L/s, otherwise these may also become plugged and/or blocked by floatables in the catch basin. This device also restricts unwanted odours from the combined sewers as it has an extended intake arm

that is submerged under the water level. (Figures 4 and 5) Another product that has been modified over the years is what the City of Ottawa refers to as â&#x20AC;&#x153;the trap assemblyâ&#x20AC;? which it fabricated to limit the flow in

catch basins, act as an odour trap, and for control of floatable debris. (Figure 6) The latest version of the trap assembly mounted to a display board is ideal for achieving different flow restrictions just by selecting a different hole size on the

front face. It also has a very good gasket and is easily removed by City operations staff if need be. It has proven to be ideal for the control of floatables. (Figure 7) In addition to restricting inflow into the catch basins, the City uses an insert under the manhole covers for both sanitary and storm sewer systems.

City of Barrie upgrades water pollution control centre and systems

he City of Barrie in southern Ontario is one of Canadaâ&#x20AC;&#x2122;s fastest-growing municipalities. Its growth has been fueled by its location in the heart of Ontarioâ&#x20AC;&#x2122;s playland and its strategic proximity to Toronto. Recognizing that sustainable growth requires a dependable and reliable infrastructure, the City of Barrie has implemented a strategic plan to establish and support a comprehensive modernized wastewater facilities PLC/SCADA (program logic controller/supervisory control and data acquisition) systems network. A key factor in the assessment of any SCADA system is a review of the existing system network architecture and platform. The aging PLC/SCADA system at Barrieâ&#x20AC;&#x2122;s water pollution control centre (WPCC) was installed in the early 1980s and has sustained ongoing improvements and modifications to parallel growth of the facility over the years.

The upgraded system consists of 14 process control stations within the WPCC and 14 remote pump stations, with the various control stations linking the controllers together in a proprietary network. The WPCC Process Control Systems (PCS) Upgrade Design-Build project consisted of the following: 1. New fibre-optics communication network throughout the WPCC facility. New unit process PLCs and SCADA platform were installed in a sequential approach, one control panel at a time, to avoid operational interruptions at each WPCC process area and remote pump stations. 2. New SCADA and PLC process control narratives, overall PLC programming and SCADA standards. The project has had many challenges because the pumping stations and the plant processes must remain operational during the controller upgrades. During project execution, there were essentially two network systems tem-

porarily operating in parallel (existing and new) during the transition and commissioning phase of the project from old works to new. Once the new system network was commissioned, one control panel at a time, the old processor and network function was decommissioned and removed. 3. Upgrading of the Wood Street remote pump station, including civil, structural, architectural, mechanical, electrical and instrumentation works. The project team was required to work closely as a cohesive unit with City operations and maintenance staff, designers, construction managers, process specialists, system integrators and software development programmers. One of the most challenging aspects of the project was the completion of the unit process area SCADA installation for facilities also undergoing a separate major hydraulic capacity process expansion (76 megalitres per day) concurrent with the

Septage

Septage waste - itâ&#x20AC;&#x2122;s in your backyard By Colleen Swider

he infrastructure in Canada is crumbling and Ontario will require 30 - 40 billion dollars in capital investment to upgrade its water and wastewater infrastructure over the next 15 years. Municipalities continue to grow, without adequate plans for urban and rural liquid waste disposal programs to address the increasing volumes of septage and sewage. Septage waste in septic tanks should be pumped out approximately every three years, depending on the size and the impact factors on the tank. With over two million rural households in Ontario that are on private septic systems, generating over 27 billion litres of septage waste annually, the question is: where does it go? This has been a problem for governments and municipalities, large and small. In Ontario, the Provincial Policy Statement (2005) states that lot creation on pri-

vate, communal or individual septage services is only permitted if there is confirmation of reserve sewage system capacity. Reserve sewage capacity is sufficient if the septage from the development can be treated or disposed of at sites approved under the Environmental Protection Act, or the Ontario Water Resources Act. There is a need to have capacity for the septage by the time the development is completed. Capacity does not include management by land application of untreated septage. The management of septage in Ontario must incorporate alternative viable treatment options. There is a general misconception that septage waste must go to a wastewater treatment plant to be processed. Many municipalities are not in a position to comply with the Provincial Policy Statement and they need to develop a plan to ensure that the increased development of their municipality evolves si-

multaneously with the ability to manage and dispose of the septage created. They must create the infrastructure to support their developments. Municipalities must have an urban and rural septage waste management plan, similar to their solid waste management plans. The Ontario Association of Sewage Industry Services (OASIS) is a provincial association established in 1991 to represent septage pumpers and haulers, sewage system installers, manufacturers and professionals. Its role and responsibility is to look after the liquid waste removal needs of customers in rural areas. OASIS members decided that they needed to be proactive in finding ways to address the treatment and disposal of septage and portable toilet waste. In 2007, OASIS created the Rural Wastewater Treatment Expo to look at alternative technologies and to address the treatment of septage in a sustainable, cost-effective and environmentally friendly way.

Installation of a sloping sand filter.

Organizations and companies in the wastewater industry are invited annually to display their technologies, including on-site, hands on demonstrations. This annual event provides an opportunity for

municipalities, plant operators and other decision-makers to learn about advances in septage treatment. In 2008, Expo participants toured a converted beaver pond that has been act-

ing as a lagoon system for the Village of Washago in Severn Township, Ontario, which has 500 homes. This system has been successfully in use since the late 1980s. The Township of Bonnechere Valley, Ontario, invested in Geotube technology to assist with their dewatering process for septage. (See page 38 of the March 2009 issue of this magazine). This technology was demonstrated at the OASIS annual Expo for the past two years and is used worldwide for dewatering septage. Other solutions showcased at the Expo include composting, reed bed technology pilot projects in Muskoka, the Fournier Screw Press Technology, Volute Dewatering Press Technology, and dewatering septic trucks.. During a recent visit to Nova Scotia, OASIS representatives met with Robert G. Anderson, with Nova Scotia Environment, and Don Reid, who are finding innovative ways to deal with septage issues in the Maritimes. While touring the septage pilot projects at Dalhousie University, Don Reid continued overleaf...

Septage described sloping sand filters, a practical solution for on-site disposal on difficult sites. Sloping sand filters have been used in Nova Scotia for over 20 years. Until recently, their use was restricted to upgrading existing malfunctioning systems. Due to their proven advantages over other options and the results of testing carried out by the Centre for Water Resources Studies at Dalhousie University, sloping sand filers have recently been approved to serve new construction

in Nova Scotia. A cross-section of a typical sloping sand filter is shown in Figure 1. In a typical system, septic tank effluent flows to a distribution trench with a linear loading rate between 60 and 100 L/day/m and basal loading rate of 33L/day/m2. The specifications for sand used in sloping sand filters (â&#x20AC;&#x153;filter sandâ&#x20AC;?) result in a sand that is similar to one meeting the CSA A23.1 specification for concrete sand. There is 450 mm of filter sand under the

distribution trench and a minimum of 5 m of filter sand from the down slope of the edge of the distribution trench. The minimum slope on the base of the filter is 3%, although typically it is kept above 5%. The maximum slope on the bottom is limited by the ability to work on the slope, which is generally less than 30%. In many cases, direct discharge is not required. In 2004, six sand filters with a similar cross section to that shown in Figure 1 were installed at the On-Site Wastewater Research, Evaluation and Training Facility located at the Nova Scotia Agricultural College in Truro. Three of the filters have a slope of 5% and three have a slope of 30%. Filters at each slope contain sands with permeability of approximately 1.5 x 10-4, 5 x 10-4 and 1.0 x 10-3 m/sec. These filters have been receiving septic tank effluent since that time. The initial idea was to compare the treatment received from the different sands at the different slopes. However, extensive sampling has shown that all sands at all slopes have continued to provide a high level of removal of BOD, SS and E.coli. Typical effluent quality from all filters would contain: BOD < 2.4 mg/L, TSS < 10 mg/L (some would be coming from the backfill) and E. coli < 5 CFU/100 mL. When loading rates were doubled and when down slope sand buffer widths were reduced to 2.5 from 5 m, filters continued to produce similar treatment efficiencies. Experience has shown that sloping sand filters offer a number of advantages, including: 1. Lower construction and operational costs. 2. Aesthetic acceptance by the homeowner as the installed filter is totally below grade and invisible. 3. Ease of installation using locally available materials. 4. Minimal maintenance other than routine pumping of the septic tank. 5. No operational energy consumption other than when pumping is required on larger systems to give pressure distribution. 6. Demonstrated long-term trouble free performance. 7. Small footprint. 8. Treated effluent meets stringent discharge criteria.

Figure 1. Cross-section of typical sloping sand filter.

It is anticipated that, with the recent changes that allow the use of sloping sand filters to handle the disposal of sewage from new residential construction in Nova Scotia, the numbers of sloping sand filters installed will increase significantly. It would seem appropriate for other jurisdictions to consider their use as an option for onsite sewage disposal.

OASIS continues to work together with the Ontario Ministry of the Environment, various levels of government including municipalities, and other associations to address the issue of septage disposal and treatment in Ontario. Municipalities must be responsible for the septage waste generated in their “backyards”. As each municipality faces the question of “what can and should they

do”, engineers will be called upon to find solutions to their problems. Often the simplest changes can result in better outcomes. For example, when engineering a receiving station whose purpose is the offloading of septage, creating a slope will allow gravity to assist in the process, resulting in a complete offload. This reduces the impact on the equipment, especially during the winter months. Another example is having the receiving pipe below the level of the pumper truck to allow for gravity discharge. When a pumper or hauler has to discharge their load of septage upwards, against gravity, it has the potential to cause a spill. In conclusion, there are many innovative and practical ways to deal with septage management and disposal. It requires a team approach to find cost-effective and environmentally friendly solutions.

Regulations

Ontario accused of not keeping industrial waste from the Great Lakes

nvironmental groups are urging the Ontario government to stop ongoing pollution of the Great Lakes, by fixing stagnant and ineffective discharge regulations. Ecojustice, Great Lakes United, and Environmental Defence have submitted an application to the Ministry of the Environment, calling for a review and amendment of the Environmental Protection Act’s Municipal Industrial Strategy for Abatement (MISA) regulations. “The stated goal of the MISA regulations is the virtual elimination of persistent toxic contaminants from industrial discharges,” said Ecojustice Senior Scientist, Elaine MacDonald. “Instead of eliminating pollution to Ontario’s water bodies, MISA has become stagnant and ineffective.” The nine MISA regulations came into force between 1993 and 1995 and regulate approximately 140 major industrial facilities in Ontario. The regulations are

supposed to be reviewed every five years, with the expectation that they will gradually be strengthened as pollution abatement technologies improve. To date, no review of MISA has been conducted, and the standards embedded in the regulations remain largely unchanged over the past 15 years. MISA is also contributing to Ontario’s sewage system problems. Hundreds of industries that dump wastewater into municipal sewers have not been regulated under MISA as intended, resulting in untreatable toxic pollution entering the province's sewage treatment facilities. The application is also calling for industries to be required to pre-treat their waste before discharging to a municipal treatment system. “Industries are effectively being allowed to blindly plug their pipe into the municipal sewer,” said John Jackson, Director of Toxics and Clean Production, Great Lakes United.” We need a provin-

cial system that places responsibility on the polluter to ensure their discharges do not cause harm.” MISA regulations were set up by Ontario as one of its commitments under the Canada – US Great Lakes Water Quality Agreement, to eliminate persistent toxic substances from the Great Lakes Basin. “An updating of the MISA regulations will force much needed investment in Ontario’s industrial sector,” said Mike Layton, Deputy Outreach Director, Environmental Defence. “That investment will mean better health for the millions of Ontarians that draw their drinking water from Great Lakes.” The application makes seven recommended changes to MISA to ensure the progressive and continual reduction of pollution discharges into Ontario’s waterways.

Understanding the importance of electrical power quality

ost of the more important international standards define power quality as the physical characteristics of the electrical supply provided under normal operating conditions that do not disrupt or disturb the customer’s processes. Therefore, a power quality problem exists if any voltage, current or frequency deviation results in a failure or bad operation of a customer’s equipment. However, it is important to note that the quality of power supply basically implies voltage quality and supply reliability. Voltage quality problems relate to any failure of equipment due to deviations of the line voltage from its normal characteristics; supply reliability is characterized by its adequacy (ability to supply the load), security (ability to withstand sudden disturbances such as system faults) and availability (focusing especially on long interruptions). When power is generated, it has very predictable characteristics. It energizes all electrical equipment equally and satisfactorily. However, as the power travels through the wires and energizes the equipment, the various pieces of equipment it energizes can change the quality of the power, making it less suitable for the next application. These changes in power quality are especially common in large industrial and commercial complexes and

www.esemag.com

include increases and decreases in voltage, momentary power outages and “noise” on the electrical system. At its most extreme, poor power quality can even cause equipment to malfunction. A power voltage spike can damage valuable components. Approximately 30 to 40 percent of all business downtime is related to power quality problems which can result in: • Lost productivity and idle people and equipment. • Lost orders, goodwill, customers and profits. • Lost transactions and orders not being processed. • Revenue and accounting problems such as invoices not prepared, payments held up, etc. • Customer and/or management dissatisfaction. • Overtime required to make up for the lost work time. Power quality is an issue that needs continual attention. In recent years, it has become more critical because of the increase in the number of loads sensitive to power disturbances, and because the loads themselves have become a major cause of the degradation of power quality. For utilities, the goal of providing adequate power quality has been a moving one because of changes in user equipment and requirements. From the cus-

tomer’s standpoint, problems stemming from the sensitivity of new equipment to service quality have come as a rude surprise. Power system disturbances not only affect customer equipment or businesses, but are also detrimental to the operation of the power utility. These adverse impacts include: • Overheating of cables. • Increased eddy losses in transformers. • Incorrect operation of protecting devices. • Errors in energy metering. Common power distortions and disturbances Disturbances that affect power quality are bound to occur. Some may only briefly interfere with the most highly sensitive equipment. Others, due to extensive damage on the electric delivery system, could result in the total loss of power for days. There are a variety of different types of distortions and disturbances. 1. Voltage sags or undervoltages - A voltage sag is a momentary (less than a few seconds) decrease in voltage outside the normal tolerance. The starting of heavy loads, lightning, and power system faults cause voltage sags. A good example is the starting of a motor. Motors draw continued overleaf...

Plant Operations more current when they are starting than when they are running at their rated speed. Consequently, the starting of a motor causes a voltage sag while it accelerates to its rated speed. Excessive load changes may also cause voltage sags. Computer equipment and controllers may power down depending on the duration and magnitude of the voltage sag. In addition, voltage sags cause loss of data. One way of reducing this damage would be to connect computers and other sensitive electronic devices to circuits other than the ones that large motor-driven appliances are on, to try to lighten the load on the affected circuit. If the sags last longer, it is classified as under voltage, which is usually caused by circuit overloads, poor volt-

age regulation and intentional reduction by the utility. The impacts of under voltage include equipment shutdowns, and the overheating of motors. 2. Transients - Transients can be defined as a sudden, brief increase in current or voltage in a circuit that can damage sensitive components and instruments. These disturbances are shorter than sags or swells, and are caused by sudden changes in the power system. Two main categories of transients based on their duration are switching surge and impulse spike. Switching surges are caused as a result of resonating circuits with switching devices. Large capacitor bank switching can cause resonant oscillations, leading to surges causing tripping or even damaging protective devices. Electronically

controlled industrial motors are particularly susceptible to these transients. Impulses are very short duration spikes, in the order of a few microseconds. They are mainly caused by lightning strikes, arcing and insulation breakdowns. Most power systems are protected from surges and spikes using a TVSS (transient voltage surge suppression) device and by surge dividers and arc-gaps at high voltages and avalanche diodes at low voltages. If these disturbances are encountered by monitoring systems, depending on the magnitude of the spike, it may saturate or damage the monitoring sensors. Power outages Storms, when they are accompanied by heavy wind and lightning, are among

Plant Operations the major causes of power outages. Lightning looks for the quickest path to the ground. It generally searches for the tallest object to serve as a conductor. Utility poles, wires, transformers and other electrical equipment are easy targets for lightning strikes, causing severe damage and loss of power. Lightning also frequently strikes trees, causing tree limbs or even large trees to fall onto utility lines. Wind may cause power lines to swing together, resulting in a fault or short circuit that interrupts service. Strong winds can blow tree limbs or entire trees into power lines, causing them to fall to the ground. Severe winds can even break power lines and utility poles, bringing down extensive portions of the infrastructure that delivers power. Winter storms are a threat to electrical equipment when snow and ice buildup on power lines and tree limbs. The weight of the snow and ice can cause wires to break. Tree limbs also become heavy with snow and ice, causing them to break and fall into power lines. Heavy rain and melting snow can cause flooding which can damage electrical equipment. Momentary outages Momentary outages, which are seen as a dimming or flickering of lights or even a brief loss of power, are caused by short circuits. Short circuits happen when something, such as a tree limb, comes into contact with power lines or when the lines touch each other. When a short circuit occurs, a safety device called a breaker automatically de-energizes the circuit and interrupts the flow of power. Electrical equipment is designed to quickly open and close the breaker two or three times automatically in an attempt to clear the problem. Harmonics For the majority of the twentieth century, the predominant use of electricity for business and industry was to power motors, lights and heating devices. These uses have little effect on the 60 Hertz (cycles per second) sine waveform of the electricity delivered to them from their utility. They are referred to as linear loads, because the current rises and falls in proportion to the voltage wave. A few industries, like steel mills and aluminum smelters, used electricity to power arc furnaces, which distorted the sine waveform, because the current flow www.esemag.com

was not proportional to the voltage. These loads are referred to as non-linear loads. Non-linear loads cause waveforms that are multiples of the normal 60 Hertz sine wave to be superimposed on the base waveform. These multiples are called harmonics. In the last 20 years, there has been an explosion of microprocessor-based equipment which is also a non-linear load. Equipment widely used in offices and manufacturing not only creates harmonic issues, but is also susceptible to

harmonic disorders and problems. This kind of equipment includes computers, monitors, adjustable speed drives, welding equipment, transformers, etc. The list goes on and on. As can be seen, the invention of all these sophisticated electronic gadgets and circuitry has increased the problems associated with harmonics immensely.

important as it provides a continuous “health check” of a facility’s power system. It provides data to see, diagnose and avert looming problems. The monitoring of power quality includes the detection of electrical disturbances such as sags, harmonics, swells, etc. Once the disturbance has been detected and recorded, analysis of the captured waveforms can give more information about the disturbance. Table 1 illustrates the high speed waveform capture of power quality problems and possible solutions.

Transient voltage surge suppressors (TVSS/SPD) are one of the most costeffective first steps toward power quality management. TVSS systems are generally specified to protect the incoming AC power at the service entrance, the branch panels, and individual sensitive loads. Additionally, signal and control circuit conductors are also protected and eliminate any activity from coming in “the back door”. Transient voltage surge suppression should be considered mandatory when

there are safety-to-life and public safety considerations involved in a given application. Additionally, TVSS equipment should be specified when there is a potential for significant economic loss, and/or the potential for litigation exists. The proper application of transient voltage surge suppression equipment provides the foundation for cost-effective power quality management. TVSS protection should be applied to: municipal water and wastewater treatment plants; manufacturing systems; industrial robots; power system controllers; food processing plant controllers; petrochemical plant controllers; and vertical transportation (e.g. elevators) and remote storage and retrieval systems. The common thread which runs through these protection applications is that, when life, safety, significant amounts of money, or customer service are at risk, the system should be protected.

Drinking Water

Ontario’s MOE wins IPAC Award

ntario’s Ministry of the Environment is putting the province centre stage as a national leader in drinking water protection. The ministry’s Drinking Water Management Division (DWMD) recently won a national award for its role in transforming Ontario’s approach to drinking water protection, through the establishment and implementation of an innovative and strategic drinking water protection model known as Ontario’s drinking water safety net. The IPAC Silver Award for Innovative Management was accepted by John Stager, Ontario’s Chief Drinking Water Inspector, at the Institute of Public Administration of Canada’s annual conference and awards ceremony on August 25, 2009, in Fredericton, New Brunswick. Established in 1990, IPAC’s prestigious national awards are co-sponsored by IBM Canada and KPMG and recognize exceptional management within the public sector.

Worker Safety

Confined space rescue – emotion vs. reason By Mark van der Feyst

Sahara® Leak Detection Oﬀers Bigger ROI

onfined spaces are common in the workplace, and every day many employees find themselves working inside them. There are numerous dangers associated with entering a confined space, dangers that may be known to the entrant and the attendants, or may not. With increased regulation surrounding confined spaces, we are now in an era where the dangers are required to be known prior to any entry. Yet some workers or would-be rescuers still enter confined spaces without knowing the hazards. For example, in August 2000, on a farm in Drayton, Ontario, a repair needed to be made on the inside of a manure spreader. A worker who entered the spreader to fix the problem was quickly overcome by hydrogen sulphide gas that was present inside. Two co-workers entered to make a quick rescue and immediately collapsed. A third rescuer then

A Sahara® inspection program for large diameter water distribution mains offers a bigger financial and environmental return on investment (ROI). PPIC inspections have identified an average of 1.4 leaks per mile of large diameter pipelines in North America alone. Sahara® is the most trusted leak detection system in the world. By uncovering small leaks today, pipeline operators can minimize large leaks and ruptures in the future. For more information visit www.ppic.com/Sahara or call 1-866-990-2466. Your Pipeline.

entered the spreader and tried to rescue the last victim, but failed to do so. He was able to exit the spreader just in time. Two of the rescuers died and the third was seriously injured. The first victim was just inside the opening of the spreader and the rescuers could have simply reached in and grabbed him. The worker and the rescuers were all unaware of the presence of hydrogen sulphide gas. We have seen this type of incident happen time and time again. Why does it happen? The facts about confined space entry First, let us examine why we enter confined spaces. There are many different types of confined spaces, the most common being manholes, tanks, digesters, pits, silos, tankers, pipes, tunnels, vaults and wells. The number one space for entry is the tank. Tanks are a common space on most industrial sites. They are used to store materials, as hold-

ing tanks or to collect process waste or byproducts. They need to be entered for maintenance, either of the mechanical devices they contain or of the tanks themselves. Maintenance is the primary reason for entering confined spaces on a regular basis. One survey showed that the second main reason is for rescue. It’s sad but true that we enter confined spaces for rescue almost as often as we do for maintenance. Statistics show that 60% of confined space fatalities are rescuers (would-be). About 90% of confined-space rescue operations are recoveries and fewer than 2% of confined-space fatalities are due to physical trauma. That means the majority of fatalities are due to other hazards. More than 55% of fatalities are a result of a hazardous atmosphere (Figure 1), and about 25% of confined spaces are toxic before entering. In nearly half of the cases involving death, no monitors or ventilation were

Worker Safety used. In incidents involving fatalities, 25% had two victims and 11% had three or more victims. One-third of all deaths were supervisors. These facts highlight a serious problem with confined space entry. Atmospheric hazards for the most part are not visible to the naked eye, and by the time we are able to smell the hazard, it is already too late. Of the common atmospheric hazards that are found in confined spaces, hydrogen sulphide tops the list (Figure 2). Why do we attempt rescue when we are faced with these numbers? Our emotional response dictates our actions and, unfortunately, can often lead to serious injury or death. When a co-worker or a person we know is in trouble, we instinctively want to help. The same thing happens every winter when a family pet falls through the ice of a frozen lake and the owner acts on emotions and tries to rescue the animal. Often the owner becomes the fatality and the animal survives the ordeal. It is important to keep our emotions in check and use reason to dictate our actions. In an incident involving con-

fined space entry, there is a reason why the entrant went down. By reasoning and observing, we should be able to make the right decision. This is also a matter of training personnel to realize that their own safety comes first, the team members/public come second and the victim comes third. This may sound selfish, but it will save lives. If we always put our own lives and well-being first, we will reduce the number of fatalities of would-be rescuers. The importance of preparation It is also essential to be prepared for potential difficulties with confined space entry. This starts with entry preplanning. The first step is to identify what type of confined space we are entering. Knowing what local or provincial regulations dictate is also a must. Filling out the proper paperwork and taking the proper steps will guide us to ensure a safe entry. It will also involve appointing the right people to oversee and participate in the confined space entry. Identifying the hazards is an important part of preparing. We need to know what hazards exist inside the confined space, and then implement a control

measure for each of them. This will eliminate the chance of that particular hazard being a threat to the entrant once the confined space entry begins. We need to prepare for the confined space entry by ensuring that we have the proper equipment on-site and an adequate number of personnel, and that we have set up proper entry procedures, barricaded any unauthorized entry and notified all personnel involved of the confined space entry planned for the day. Having an established rescue plan is a must and a legal requirement in most jurisdictions. This plan will outline the actions that are to be taken by the on-site personnel in the event of an incident. Any confined space entry can be safe if we are prepared, use our reasoning skills and keep our emotions in check. This is not an easy task and requires discipline, with consistency in both training and operational execution. Mark van der Feyst is with ACUTE Environmental & Safety Services Inc.

How mercury becomes toxic in the environment

aturally occurring organic matter in water and sediment appears to play a key role in helping microbes convert tiny particles of mercury in the environment into a form that is dangerous to most living creatures. This finding is important, say Duke University environmental engineers, because it could change the way mercury in the environment is measured and, therefore, regulated. This particularly harmful form of the element, known as methylmercury, is a potent toxin for nerve cells. When ingested by organisms, it is not excreted and builds up in tissues or organs. In a series of laboratory experiments, Amrika Deonarine, a graduate student in civil and environmental engineering at Duke’s Pratt School of Engineering, found that organic matter and chemical compounds containing sulfur – known as sulfides – can readily bind to form mercury sulfide nanoparticles. Since they are

more soluble than larger particles, these nanoparticles may be the precursors to a process known as methylation. “When the organic material combines with the mercury, it prevents the particle from accumulating with other mercury

particles and growing larger,” said Deonarine, who presented the results of her analysis at the summer annual scientific sessions of the American Chemical Society (ACS) in Washington, D.C. “Since the mercury remains in a

Health nanoparticle size, it can easily collect on the surface of microbes where any mercury that dissolves can be taken in by the microbes,â&#x20AC;? Deonarine said. â&#x20AC;&#x153;Without the organic matter, the mercury sulfide nanoparticles would grow too large and become insoluble, thus reducing the availability of mercury for microbial methylation.â&#x20AC;? It is while inside the microbe that the mercury is converted into the harmful methylmercury form, the researchers said. These reactions can only take place in cold water environments with little to no oxygen, such as the zone of sediment just below the bottom of a body of water. Other such anaerobic environments can also be found in wastewater and sewage treatment systems, the researchers said.

â&#x20AC;&#x153;These initial laboratory findings could have far-reaching implications,â&#x20AC;? Hsu-Kim said. â&#x20AC;&#x153;That these reactions can take place in anaerobic environments suggests that the old paradigm of testing for toxic metals in sediments may provide an incomplete picture of how much methylmercury is there.â&#x20AC;? The researchers plan to continue their studies with other types of organic matter and for longer periods of time. For her presentation and paper, Deonarime was one of six recipients of the

C. Ellen Gonter Environmental Chemistry Award, given annually to graduate students. The research was supported by the federally funded Center for the Environmental Implications of NanoTechnology (CEINT), which is based at Duke, and the ACSâ&#x20AC;&#x2122;s Petroleum Research Fund.

That these reactions can take place in anaerobic environments suggests that the old paradigm of testing for toxic metals in sediments may provide an incomplete picture of how much methylmercury is there. â&#x20AC;&#x153;The exposure rate of mercury in the US is quite high,â&#x20AC;? said Heileen HsuKim, Duke assistant professor of civil and environmental engineering and senior member of the research team. â&#x20AC;&#x153;A recent epidemiological survey found that up to 8 percent of women had mercury levels higher than national guidelines. Since humans are on top of the food chain, any mercury in our food accumulates in our body.â&#x20AC;? Because fish and shellfish have a natural tendency to store methylmercury in their organs, they are the leading source of mercury ingestion for humans. There are many ways mercury gets into the environment, with the primary sources being the combustion of coal, the refining of such metals as gold and other non-ferrous metals, and in the gases released during volcanic eruptions. The air-borne mercury from these sources eventually lands on lakes or ponds and can remain in the water or sediments.

Water Reuse

New electrocoagulation process increases industrial water reuse efficiency

he impact of polluted water is a top environmental issue for industries around the world. As pollution garners more and more attention in the media, and as industry faces increasingly high costs for disposal, it is apparent there is a growing need for scaled-down, decentralized water treatment solutions, especially if they create reuse options. Ground Effects Environmental Services Inc., (GEE), located in Regina, Saskatchewan, recently developed the Electro-Pure™ Technology (EPT), a vacuum-enhanced electrocoagulation process that will allow on-site treatment of polluted water for reuse. As EPT moves into its first large-scale pilot test, the results have been extremely positive. The research shows that removal rates for the majority of compounds are below criteria. Joel Wolensky, GEE’s Director of Research, comments that “electrocoagulation has been around for roughly 100 years, but with new technologies and research being developed all the time, we thought we’d review electrocoagulation with a new focus on co-existing approaches. The results show that electrocoagulation is an extremely viable option for water decontamination now.” Essentially, EPT applies direct current (DC) through select electrodes to

create an electrical field in the contaminated wastewater. Contaminated ions and colloids are mainly held in solution by electrical charges. The electrical field destabilizes the contaminants within the wastewater, causing chemical reactions and precipitation or coalescence of colloids within the wastewater. The contaminants can then be removed by flotation using a skimming mechanism or by settling on the bottom where they can be removed. The electrodes used in the process are dependent on the type of contaminants present. For example, aluminum or iron

might be used separately or together depending on what contaminants are being treated. The application of vacuum enhances the ability of the technology to treat the wastewater. By reducing the atmospheric pressure within the treatment cell, the interstitial tension is reduced, allowing for release of the contaminants bound to the water molecule. The coagulative ability of the waste stream is increased, resulting in high removal rates of the contaminants of concern. An in-depth look at electrocoagulation In the process of electrocoagulation, sacrificial anodes dose a solution with metal cations released by the anode. The amount of current applied to the waste stream influences the ion dosage from the electrodes, bubble generation rates, and the dominant method of separation. The current can be monitored and adjusted to optimize treatment of specific contaminants. When water is present, the metal cations are hydrolysed to a form that can coagulate contaminants. Despite the amount of water present in a sample, cations released at the anion can be evolved into the solution and will bond with negatively charged ions and colloids. Some coagulated contaminants will be heavier and tend to settle out due to increased size and weight.

Water Reuse If the current density is low, then aggregation of bubbles and particles is slow and the bubble density will also be low, causing the aggregated contaminants to settle out. Others can be carried to the surface by the gas bubbles created within the electrolytic cell. The application of current has a direct effect on bubble formation; low current produces slow-moving, low-density bubbles, while high current produces dense, quickly-rising bubbles. Both sedimentation and flotation can be integrated into a design. The electrolysis of water involves chemical reactions producing oxygen gas at the anode and hydrogen gas at the cathode. This decomposition of water can release contaminants bound to the water molecule, resulting in the contaminants being destroyed or removed. The current, flow rate, and pH are controlled parameters within the EPT system. These parameters are adjusted depending on the type of contaminant present as well as the concentration of the contaminant. continued on page 103...

Waste Management

Crushing fluorescent bulbs – saving money and the environment

hile compact fluorescent lamps (CFLs) are gradually finding their way into homes, fluorescent lighting has long been the choice of facilities that want to cut energy costs and reduce their impact on the environment. The switch makes good sense as changing to fluorescent lighting cuts energy usage for buildings by up to 75%. But there is an environmental tradeoff for the energy and cost savings resulting from fluorescent lighting. Inside each fluorescent bulb there is a small amount of mercury, a toxic element that can adversely affect human and environmental health if released into the air or a water table. When fluorescent bulbs are in use they are perfectly safe; no mercury is released when the lights are on or off in a building. The risk for mercury pollution starts when the bulbs break, and this usually happens during their disposal. Whether it is when the bulbs are smashed in a dumpster or later when they break at the landfill, the mercury eventually finds its way into the environment. If bulbs are broken in a landfill, the surrounding groundwater and land can be contaminated, harming all who come into contact. Experts estimate that around 500 million lamps are sent to landfills each year, resulting in the release of more than 30,000 pounds of mercury. The vapours can persist in and around a facility after breakage for a long time, being breathed in by employees or others who are in the building. The negative effects of mercury on people and the environment are manifold. It is a potent neurotoxin, and mercury exposure can adversely affect the brain, kidneys and liver in humans and can cause developmental problems in children. When introduced into the environment, mercury can contaminate large areas of land and water, accumulating in wildlife (usually fish), which are eaten by humans. Mercury is so potent that just one gram from the atmosphere can contaminate a 20-acre lake for one year. Frustrating solutions Fortunately, most facilities started 46 | January 2010

looking for a safer method of disposal. They have also discovered that recycling is not expensive; over the lifetime of a lamp, the cost of recycling is less than 1% of the total cost of ownership. Recycling lamps became the accepted disposal method, as the mercury could be safely removed by machinery at specialized recycling centres. Additionally, government regulations were soon put in place in many jurisdictions to require facilities to dispose of their bulbs through certified recyclers. If they do recycle their bulbs, most facilities do so by boxing them up and arranging for a pickup by the recycler. However, facility staff often find this process frustrating as it takes up significant amounts of time collecting spent lamps in their building complex and boxing them for pickup. Sheela Backen, integrated solid waste program manager at Colorado State University, oversaw a complex and expensive method of bulb recycling. Her staff would pack lamps into their original cartons and load them onto a truck for transport back to a recycling facility. “That method presented a lot of problems,” Backen says. “We couldn’t get people to make sure the cartons were full, taped and marked with the date. When the truck was coming to pick

them up, we would have anywhere from six to eight people filling boxes, taping them back up, and then loading this truck. It was not cost-effective at all.” Lamp crushing: A smart alternative An alternative method of bulb disposal has recently emerged that rewards facilities and staff with low costs, increased efficiency, space savings and environmental benefits. This method is lamp crushing, which is actually as simple as it sounds. Once lamps reach the end of their life, they are fed into a machine that breaks them down into tiny pieces. Many lamp crushers also have a filter that is used to capture mercury vapours from the broken tubes. After crushing, the material is picked up by a recycler for further processing. Since crushed lamps take up a smaller amount of space during transport, and since they have already been processed, the cost of recycling the crushed material is reduced. The Bulb Eater, a lamp crusher available from Air Cycle Corp., crushes fluorescent tubes of any size while removing the mercury vapours in each lamp with a three-stage HEPA filtering process. The machine itself takes up very little space; it sits on top of a 55-gallon drum that holds the lamps after they are crushed. A single drum can hold up to

Waste Management 1,350 crushed T8 four-foot lamps. Because the machine can crush a four-foot lamp in just one second, facilities can reduce labour by 20 hours per 1,000 lamps compared with boxing up lamps for pickup. They can also save up to 50% on recycling costs when they schedule a bulk recycling pickup for their crushed lamps. And since hundreds of lamps fit into one drum, facilities can minimize their spent lamp storage space by using the bulb-crushing machine Sheela Backen describes her facilityâ&#x20AC;&#x2122;s experience with the Bulb Eater: â&#x20AC;&#x153;The bulbs are brought to a specific location. I send one person over there for a couple of hours a week to crush the tubes. Itâ&#x20AC;&#x2122;s very quick and efficient, and I donâ&#x20AC;&#x2122;t have to waste so much time trying to load a truck.â&#x20AC;? Seeing green results Lamp crushing has helped facilities save money, space and time over other lamp disposal methods. However, some facilities began to want a better understanding of the impact on the environment of crushing their bulbs. Air Cycle responded by introducing online recycling reports, a tool that Bulb

Water Supply

Pathway to urban water sustainability in British Columbia By Kim A. Stephens

he Province of British Columbia has put in place a policy framework that enables local governments to commit to doing business differently. The program goals for Living Water Smart, BC’s Water Plan, and the companion Green Communities Initiative, constitute a ‘call to action’ on the part of British Columbians to manage settlement in balance with ecology. Tim Pringle, Director of Special Programs for the Real Estate Foundation of British Columbia, says that “Living Water Smart presents the vision, and the Green Communities Initiative provides enabling tools to achieve the vision. The solutions and commitments go beyond what government does. Living Water Smart supports planning that is as much about land as water.” Living Water Smart contains a key message – green development makes sense. Fostering new thinking about development leads to more green spaces, more water and fish in streams, improved community vitality, reduced demand for water, and reduced expenditure on infrastructure. Implementation Implementation of Living Water Smart and the Green Communities Initiative is being advanced through partnerships, in particular the Water Sustainability Action Plan for British Columbia. Co-sponsored by the Province and the Real Estate Foundation of British Columbia, and delivered through the British Columbia Water & Waste Association (BCWWA), the Water Sustainability Action Plan serves as a partnership umbrella for aligning actions at three levels: provincial, regional, and local. One vehicle for program delivery is Convening for Action on Vancouver Island (CAVI). On Vancouver Island, the CAVI team is playing a key delivery role in two of the five Living Water Smart theme areas: community planning and development; and efficiency, outreach and public awareness. 48 | January 2010

Shared responsibility Water issues are complex and best solved collaboratively, which includes using strategies and solutions that fall outside government control. While legislative reform is a foundation piece, collaboration takes place in the world of practitioners. “At the end of the day, planners and engineers and other disciplines must come together to determine the issues and solutions. No statute will help them do that,” says Lynn Kriwoken, of the BC Ministry of Environment. Provincial funding “A mandate of the BC Ministry of Community & Rural Development is to foster partnerships, collaboration, innovation, and integration through the program elements that comprise the Green Communities Initiative. The goal is to build capacity that will result in sustainable, healthy and vibrant communities,” continues Glen Brown, Executive Director of the Local Government Infrastructure & Finance Division of the Ministry. He is also Chair of the BC Water Sustainability Committee. Ultimately it is the Ministry’s grant programs that provide the incentives that enable the Province to influence local government behaviour, and to reward those who meet program objectives for doing business differently ‘on the ground’. The Green Communities Initiative encompasses a number of plans and strategies that directly complement and/or support Living Water Smart policies. The reality of an increasing local government infrastructure deficit means that there will be even stiffer competition for available funding. As a result, there is a greater incentive for local governments to demonstrate how their innovation and integration will be effective

Tim Pringle

in meeting the goals of both the Green Communities Initiative and Living Water Smart. Rewarding innovation and integration According to Mr. Brown, infrastructure grant programs have evolved over the past decade in British Columbia. In the past, those local governments which had poorly managed their infrastructure systems were essentially rewarded with grants to rectify problems resulting from a lack of planning. Now, those local governments which are proactive and showing leadership are the ones which are being rewarded. In urban settings, measures that ‘green’ (and improve) the built environment can also protect or help restore the natural environment. How communities choose to develop or redevelop individual sites has ripple effects at the watershed scale. By designing with nature, this means actions on the ground can add up and result in cumulative benefits over time. Green vocabulary defined To help advance a new way of thinking about land development in British Columbia, the Water Sustainability Action Plan has developed and is promoting a ‘green’ vocabulary: • Green Value means that land use strategies will accommodate settlement needs in practical ways, while protecting the ecological resources upon which communities depend. • Design with Nature is one approach to achieve Green Value, and is supportive of community goals that relate to building social capacity as well as protecting ecological assets. • Green Infrastructure is the on-theground application of Design with Nature standards and practices. • Water Sustainability is achieved

Water Supply through Green Infrastructure practices that reflect a full and proper understanding of the relationship between land and water. Desired water sustainability outcomes are less irrigation water use, and reduced rainwater runoff. These are complementary outcomes. Regional team approach In general, the enabling approach means the onus is on local government to take the initiative, because the Province recognizes that communities are in the best position to develop solutions which meet their own unique needs and local conditions. A â&#x20AC;&#x2DC;regional team approachâ&#x20AC;&#x2122; is founded on partnerships and collaboration, and seeks to align local actions with provincial and regional goals. Vancouver Island is demonstrating the regional team approach. CAVI has brought together those who plan and regulate land use (local government), those who build (developers), those who provide the legislative framework (the Province), those who advocate conservation of resources (stewardship sector), and those who provide research

Water Supply

Moving forward with drinking water source protection By Juli Abouchar and Jacquelyn Stevens

he Clean Water Act is intended to protect existing and future sources of drinking water. It is a response to Justice Dennis O’Connor’s recommendation, in the report on the Walkerton tragedy, that source protection plans should be developed at the local level for every watershed in Ontario. Source protection is the first barrier of a multibarrier approach to providing safe drinking water. Since the Clean Water Act, S.O. 2006, c. 22 (CWA) was passed in 2006, the Ministry of the Environment (MOE) and stakeholders have been working hard to implement this new-to-Ontario approach to governance. The CWA provides that source protection committees, managed by conservation authorities and comprised of stakeholder representatives, will develop Source Protection Plans to be submitted to the MOE for approval in 2012. Currently, the 19 source protection committees are preparing science-based assessment reports for each of the 40 designated watershed areas in the province. The assessment reports are to identify and assess water quality and quantity threats to drinking water sources as listed in each committee’s Terms of Reference. The committees will then prepare source protection

cies could include: education and outreach, incentive programs, monitoring activities, land use planning approaches, new or amended provincial instruments, Risk Management Plans, prohibitions, or restricted land uses. Municipalities have been active participants in local multi-stakeholder source protection committee discussions. Many have already developed Official Plan policies and zoning by-laws, delineating and protecting well-head areas. While the Planning Act, R.S.O. 1990, c. P.13, addresses new land use, the CWA gives municipalities new powers to address activities, including requiring risk management plans for activities that are significant threats inside wellhead protection areas and intake protection zones, and a suite of enforcement powers similar to those of the MOE. Municipalities will also appoint risk management officials and inspectors to be responsible for the administration and enforcement of risk management plans for regulated activities, prohibitions, restrictions on land uses, and for issuing stop work or cost recovery orders, where the municipality has carried out work to reduce drinking water threats. These powers give municipalities an important role in implementing the Source Protection Plans.

Where a risk management official is satisfied that a risk management plan for a drinking water threat will reduce the potential for adverse effects to a drinking water source, such a plan may be considered. plans that will detail, and direct, the actions of public bodies and municipalities to address the identified threats to drinking water sources within the watershed area. The source protection plan policies will ensure that significant drinking water threats cease to be significant, and potentially significant drinking water threats never become significant. Poli50 | January 2010

The Ministry has been barely a step ahead of the committees and municipalities, in the development of technical and policy guidance documents. In June 2009, the MOE posted “Source Protection Plans under the Clean Water Act, 2006: A Discussion Paper on Requirements for the Content and Preparation of Source Protection Plans”, on the Environmental Registry

for public comment. In late 2009, the Ontario Ministry of the Environment (MOE) was to release draft regulations under the CWA, detailing the requirements for source protection plans based on the discussion paper and comments. The discussion paper proposes a hierarchy for the use of types of policies. The MOE proposes to encourage source protection committees to use prescribed provincial instruments as the policy approach of first choice. This should encourage a one-window approach, and avoid regulatory duplication. It will be important for the MOE to prescribe as many instruments as possible. The current list appears to be lacking certain provincial instruments that could be used for source protection. Where no provincial instrument exists, the discussion paper encourages the use of Risk Management Plans. Where a risk management official is satisfied that a risk management plan for a drinking water threat will reduce the potential for adverse effects to a drinking water source, such a plan may be considered. Risk management plans are intended to be negotiated and agreed to. Where agreement cannot be achieved, a risk management plan may be ordered for an activity that is, or would be, a significant drinking water threat. However, the discussion paper seeks to restrict the use of risk management plans to significant drinking water threats and not to those that “would be” significant. This is an unwise restriction of the CWA, as it effectively limits policies for preventing a moderate threat from becoming a significant threat. The discussion paper encourages limiting the use of outright prohibitions to when there is no alternative. Although

Water Supply planning instruments, including Official Plans and zoning by-laws, will have to conform with significant threat policies, designated Great Lakes policies, and other policies. Identification of risks to drinking water sources would restrict municipal land use and planning decisions, including undertaking any public works or passing by-laws that conflict with the CWA. The CWA provides opportunities to protect drinking water sources across Ontario. Municipalities and other stakeholders will continue to play a critical role in finding practical, workable solutions to implement and enforce drinking water source protection measures.

Operations

Ensuring reliable lift station operation

ift stations are vital to the safe and effective movement of sewage and water, especially where elevations prevent continuous gravity feed. By collecting the fluid from gravity systems in specially designed wet wells, and then pumping this up to the next stage of the gravity main, lift stations provide reliable movement of sewage and water, but only if they are properly installed and maintained. Lift, or pumping, stations can be installed in a number of configurations, either above ground, with various holding tanks designed to give easy access to mechanical parts, or below ground. Most applications in Alberta are below ground and involve multiple tank systems in order to move sewage, or water, up to higher elevations. These belowground systems might have pumps submerged in wet wells, or housed in nearby dry wells, in order to minimize exposure to effluent.

Operations The decision for either approach is usually based on the overall size of the project and on environmental factors. Installing a lift station isnâ&#x20AC;&#x2122;t as simple as digging a hole, connecting the lines and supplying power. Instead, back-up power supply, sophisticated monitoring equipment, and pump control mechanisms, must also be designed and carefully installed. Depending on the type, configuration and scope of the project, it can take from eight weeks, to more than a year, for a lift station to become operational. Many newer projects are using Multitrode probes as a more reliable means for liquid level sensoring, or are installing full pump station management technology. Most sanitary lift stations are controlled by government regulation, requiring dutiful and proactive regular maintenance and record keeping. Maintenance All lift stations require regular maintenance, in order to avoid costly and dangerous interruptions to service. It is not an easy job, and access to pumps located in sewage wet wells must be carefully monitored and controlled, as methane and other gases can quickly cause serious health problems. Following are suggested steps for maintenance: 1. In order to keep pumps running smoothly and to prevent odor, build-up, or contamination of water, it is important that wet wells be cleaned out at periodic intervals. In many cases, this means twice a year. 2. Inspecting pumps, tanks, power supplies, alarms, floats and sensors, should be part of the daily routine to keep lift stations operational. Records of inspections should be kept carefully and audited regularly. Inspections of the pump impeller should occur at least quarterly and not when motor hours are within 10% of each other. There should be no debris. Check valves should be monitored bi-yearly to ensure no chance of backflow. Float inspection should include degreasing for optimal performance. Be sure to check light and alarm systems at least weekly. 3. Be sure systems have hour meters, and use them diligently to record maintenance and inspection data. www.esemag.com

4. When auditing maintenance and inspection data, be sure to pay attention to amperage readings for motors. Changes in amperage can indicate the start of problems like propeller debris, or water in the housing and/or wiring. Sensors and alarm systems are not the only way to see problems arising. 5. Before a deteriorating part has a chance to do damage or interrupt service, it should be replaced. Anything that appears worn, misshapen or suspicious,

should be replaced immediately. By the careful monitoring and accurate and regular maintenance of lift stations, they should always provide reliable and safe operation. For more information, E-mail: mail@wilbert.ca

Will “arsenic-safe” wells remain safe? By Nadim R. Khandaker and Patrick V. Brady

here is lingering anxiety amongst the rural population of Bangladesh as to whether wells tested and marked safe (below the government’s maximum contaminant level of 50 ppb arsenic) can become unsafe (arsenic concentrations exceeding 50 ppb) over time. In collaboration with the Mukto Ongon Free Clinic, in Sardi Village, Bangladesh, an arsenic mitigation cell was set up to retest wells that were tested earlier and marked arsenic-safe. Sardi is a small village, located 50 kilometers north of Dhaka, the capital of Bangladesh, and lies in the Megna River flood plain. Dr. Nadim Khandaker provided assistance to the Mukto Ongon Free Clinic, with seed money from the Association of Professional Engineers of New Brunswick. As a starting initiative, the clinic established a program to provide the village of Sardi and surrounding ten villages, where they have been providing health and sanitation services for the past thirty years, with the added service of testing newly installed wells for arsenic, free of charge. As an added initiative, they decided to also retest wells in Sardi and the ten adjacent villages that were marked arsenic-safe in a prior testing program.

54 | January 2010

Figure 1.

An earlier testing program was conducted in 2002 by the United Nations Children Fund (UNICEF) and the Government of Bangladesh Department of Public Health and Engineering (DPHE), under their arsenic mitigation programs. Wells were screened for arsenic, using the same brand of field test kits as in the previous testing program. In the UNICEF/DPHE program, the snouts of the wellheads of arsenic-safe wells were marked green, and the owners of the wells were also provided with a test card. The status of the wells from the previous testing program was verified, wherever

possible, based on test result cards provided by DPHE to the well owners. In cases where owners had lost the records, the Mukto Ongon Free Clinic had to rely on the green marking of the wellhead snout, and on the testimony of the owner and citizens using the safe wells for their source of potable water. Paramedics, and student volunteers associated with the Clinic, carried out the testing program.Training on the use of the field test kit and proper sampling procedure was provided by Dr. Khandaker, who is a former lead engineer for UNICEF. Patrick Brady, Senior Scientist at the Sandia National Laboratory’s Geochemistry Department, served as technical advisor. Before the test, the owner of the well was asked the depth of the particular bore hole well. The well was then flushed for sufficient duration to ensure removal of any static water from the pump head, and from above and below the ground pipe. The collected water sample was then tested, using field test kits, and the result noted. Fifty designated arsenic-safe wells, with water tested to be below 50 ppb arsenic based on the UNICEF/DPHE 2002 program, were retested from September 2008 to January 2009. Retesting results indicated that 26 of the 50 wells

Jan2010_ES&E_ES&E 27/01/10 7:46 PM Page 55

Water Supply now had arsenic concentrations above the 50 ppb limit (see Figure 1). The retesting program also showed that the 90th percentile of the wells that became unsafe over time were below 160 ft (mean depth = 114 ft ; median depth = 102 ft; max depth = 210 ft; and min depth = 52 ft ). The depth profile of the wells that still remained arsenic-safe over time, showed that in general they were deeper (mean depth = 214 ft; median depth = 135 ft; max depth = 900 ft; and min depth = 57 ft ). Arsenic contamination in Bangladesh is triggered by subsurface reactions that mobilize arsenic associated with aquifer solids. Shallower wells appear to be more sensitive to changes in recharge chemistry that can liberate arsenic from aquifer solids. They may also be more prone to anthropogenic influences, such as the use of high velocity irrigation pumps that are used in the region to irrigate rice crops, grown in the dry season, with water from shallow wells. More importantly, results show that arsenic-safe wells can potentially be contaminated over relatively short peri-

ods of time. An immediate response is for organizations working on arsenic mitigation worldwide, and for persons living in arsenic-contaminated regions of the world, to more frequently retest their well water. In particular, the fre-

quency of testing for arsenic should be greater for shallower wells. For more information, E-mail: nadimkhandaker@hotmail.com, or pvbrady@sandia.gov

Cover Story

Treating wastewater on the world's largest cruise ship By John Leask

uilt by STX Europe for Royal Caribbean International, Oasis of the Seas is the largest cruise ship in the world. All black, grey, galley, food-waste and laundry wastewater generated onboard is treated to a higher quality than is required by the Alaska Department of Environmental Conservation (ADEC) standards, currently the most stringent in the world. The maiden voyage of this technologically groundbreaking ship took place in December 2009, and all systems were functional and ready for passengers prior to launch.

Parameter TSS BOD5 Fecal Coli Form

Oasis features a Headworks CleanSeaÂŽ advanced wastewater purification (AWP) system based on moving bed bioreactor (MBBR) technology. The system can efficiently treat all grey and black water to surpass ADEC standards for BOD, TSS, fecal coliform, free chlorine and pH. Late in the installation phase of the project, the company that started the contract, Hydroxyl Systems Inc., was acquired by Headworks Inc. The challenge for the Headworks Bio engineering team was to design a system capable of treating the wastewater generated on board by as many as 8,460

passengers and crew. This translated to a design capacity of 3,000 m3/day (0.79 MGD). Royal Caribbean Internationalâ&#x20AC;&#x2122;s policy is to produce effluent twice as clean as required by ADEC (Table 1). This allows Oasis to cruise anywhere in the world and surpass any wastewater discharge regulations. Design requirements Two of the most important design criteria for a shipboard AWP system are small footprint and excellent reliability. The system needs to be as small as possible to leave room for other equipment. AWP process tankage is of particular

Cover Story concern as it consumes space that could otherwise be used for potable water or fuel. Reliability is critical because replacement equipment is difficult to come by at sea, and downtime could quickly leave the ship in a situation where its wastewater storage capacity is used up and discharge is not possible. MBBR technology meets both of these criteria. It accomplishes BOD reduction, using biofilm carriers in a three-stage bioreactor process. The biofilm carriers provide a stable base for the growth of heterotrophic (feed on organic material) and autotrophic (feed on inorganic material) bacteria within protected cells. A high concentration of this biological growth thrives within the internally protected areas, efficiently removing contaminants with a tank volume significantly smaller than with

a comparable activated sludge system. The MBBR process is inherently reliable because the bacteria only need food and oxygen to flourish. The attached growth organisms within the carriers are resilient to toxicity and pH upsets, since only the outer layers of attached growth are affected. Typical suspended growth bacteria could be wiped out. The oxygen required for the biological growth to function is delivered by positive displacement air blowers, via fine bubble diffusers in the reactors. The aeration provides both the necessary oxygen for oxidation of contaminants, and the mixing energy required to fluidize the moving bed of carriers. The AWP system onboard Oasis is a complete process, including primary solids removal, secondary solids removal by dissolved air flotation, tertiary

solids removal by the positive barrier method, and UV disinfection, all in addition to the MBBR process. Extremely high reliability is achieved in these stages by using high-quality, marinegrade components and materials. In addition, the system utilizes two independent treatment trains, each designed to treat 100% of the shipâ&#x20AC;&#x2122;s wastewater production. If one piece of equipment fails, the system controller (PLC) automatically switches to the standby unit. This means that the ship will have minimal downtime, and will avoid having to discharge untreated water due to component failure. All system components have a duty and standby unit, with the exception of the bioreactor tanks, which are constructed of duplexed stainless steel and have a regular inspection cycle, so failure of the tanks themselves is not anticipated. The Oasis system improves on previous CleanSea installations, by having redundant control panels and uninterruptable power supplies to keep the system essentials (PLC controls, tank level indications, etc.) online in the event of an electrical blackout. At the time of writing, the system design had been conditionally certified as Det Norske Veritas (DNV) type approved, and was to be fully certified upon completion of successful compliance testing. Live monitoring The AWP system onboard Oasis also features advances in the live monitoring of process parameters. The measurement of pH, turbidity and residual chlorine at the discharge point allows the systemâ&#x20AC;&#x2122;s PLC to determine the effluent quality. If the effluent quality is out of specification, the system will automatically circulate the water to the start of the process for re-treatment, preventing the discharge of any out-of-compliance water. These live process parameters, and many others, allow critical performance data to be logged. Remote access to the control system allows the Headworks Bio team to monitor the system in real time, from anywhere in the world, with an Internet connection. Comparison with municipal applications To put the Oasis system into perspective, typical municipal applications may continued overleaf...

have an influent BOD5 concentration of 300 mg/l, or roughly one-third of the cruise ship application. If we consider this in terms of biological load, the AWP system on board Oasis would be similar

to treating 9,000 m3/day (2.4 MGD) of municipal wastewater, which could be suitable for a town of approximately 25,000 people. Although the effluent BOD5 and TSS

limits are well below most municipal discharge standards, there is currently no limit or treatment for the removal of nitrogen in this system. The MBBR process has lent itself very well to the challenging cruise ship application, and, over time, operators are seeing the benefits of lower energy demand and minimal consumables. The process is very efficient in terms of energy used per kilogram of BOD removed, compared to other shipboard treatment systems. In addition, the only chemicals used in the Headworks AWP system are polymer for dissolved air flotation, and defoamer for startup of the bioreactors. These two factors significantly benefit the overall lifecycle cost of the AWP system. As the cruise industry continues to fit its new and existing ships with advanced wastewater purification systems, we should continue to see growth in the application of MBBR technology.

Upgrading a 2,500 year old Roman sewer

he Cloaca Maxima is one of the world's earliest sewage systems. Roman Engineers built it to serve as the City of Rome’s main drainage system, late in the sixth century BC. Water from the baths and latrines, as well as runoff from local marshes, was collected via the wastewater system and discharged directly into the Tiber River, which ran beside the city. Collecting multiple effluents made it necessary to have large openings in the streets, which undoubtedly caused odor and sanitation problems. The system was later enclosed in the third century BC. Part of the current sewer network is still made up of these ancient underground structures. More than 25 centuries later, Roman engineers are continuing to improve the sewer systems. Only now, concerns of health, safety and tourist disruption are a top priority. The municipality of Rome designed a 54-inch diameter sewer bypass in one of its central quarters, Farnesina. The new line, 1,000 feet in length, connects two existing 138-inch diameter concrete sewer collectors. Farnesina, an area steeped in history, sits on the right bank of the Tiber River. The area is headquarters of the Italian Foreign Ministry, home to the ancient Milvio Bridge, first constructed in 206 BC, and two historically important, and still busy sports facilities, the Olympic stadium and the Foro Italico. Two major roadways converge in the area, the Cassia and the Flaminia. In order to minimize the effect of the sewer upgrades on this busy and densely populated area, a trenchless solution was sought. Care was taken during construction to minimize disruptions, so that the tourist area could keep up its busy flow, especially during sports events, when thousands of visitors gather. The microtunneling alternative, apart from being nondisruptive, also kept the construction site comparatively small. SAFAB Spa., an Italian contractor specializing in hydraulic applications, was awarded the contract and worked in close cooperation with La Falce Spa., a company with 50 years of experience and no-dig know-how. The tunnel was prepared with a slurry pipe and a tunneling boring machine, featuring a laser guidance control system. Driving through different layers of soil, ranging from clay, to sand and gravel, a daily advance of 20 to 50 feet could be achieved. The planned line consists of two straight runs (400 and 600 feet) that are connected with a 60-degree manhole that will be used for future access and inspection. The project’s main jacking station was erected at this intersection point. A circular jacking shaft was designed with a 30-foot diameter, to enable drives in the two required directions from one single pit. Two thrust shields were built to keep the relatively light machine in position, and it was simply rotated in place to the right position. The first stretch of 400 feet was excavated with the thrust from the main station. The longest stretch of 600 feet had to be driven with an intermediate jacking station. The 54-inch nominal diameter centrifugally cast, fiberglasswww.esemag.com

reinforced, polymer mortar (CCFRPM) jacking pipe from HOBAS had an external diameter of 59 inches and weighed 275 pounds per foot. Pipes on this project had an allowable thrust force up to 390 US tons. Thanks to the product’s smooth outer surface, it was possible to reduce the amount of slurry needed. Additionally, the comparatively small wall thickness reduced the amount of excavation material, while maintaining flow capacity. In fact, it limited the use of bentonite-based lubricant to the final sections of both drives, and sped up the installation rate considerably. For more information, E-mail: info@hobaspipe.com

Climate Change

Copenhagen and beyond – making the transition to a low-carbon economy By Ted Dhillon and Dr. Bernard Fleet

espite the fact that the Canadian government has yet to set a clear climate change policy, industry and businesses of all sizes need to put in place the models necessary to plan the transition to a low-carbon economy. The first step towards managing carbon emissions is to measure them, because, in business, what gets measured gets managed. This article sets out a basic road map for companies to use to plan for the transition to a low-carbon economy. The need for carbon disclosure While there is a sense of disappointment that the recent climate change talks in Copenhagen did not achieve a more positive result and set binding targets on limiting carbon emissions, this should not detract from the fact that the world is changing. The majority of scientists believe that the planet is already on an irreversible trajectory to dangerous warming. Only by shifting the global economy from carbon-intensive to low-carbon, and, ultimately, to zerocarbon products and processes, can environmental disaster be averted. Most Fortune 500 companies are certain that mandatory reporting on carbon emissions is coming. The European Union (EU) already requires monitoring and limiting emissions from its most energy-intensive industries, while Japan has required all companies, since 2003, to comply with an energy-reporting system, along with a plan to reduce energy consumption. In the US, despite the lethargy of the Bush administration, the states, with California in the lead, have shown the way, enacting greenhouse gas (GHG) emission caps, utility performance, and auto emission standards. In Copenhagen, Canada was widely viewed as a laggard in its commitment to the environment. Previously, the Harper government had stressed its intention of integrating our climate change policy with that of the US. It is now clear that the reverse is taking place, and there is a widening gap between President Obama’s clean energy agenda and Canada’s continued support 60 | January 2010

for the oil sands. Canada has already earned a failing grade in the GHG stakes. Failing to meet its modest reduction targets, its environmental reputation was further tarnished during the recent conference in Bangkok, a precursor to Copenhagen. Canada’s proposal to cherry pick parts of Kyoto for incorporation in the new COP15 (15th Conference of the Parties to the United Nations Framework Convention on Climate Change) agreement was greeted with outrage and a mass walkout by representatives of the Group of 77 developing nations. This group includes those impoverished nations that are most affected by climate change and stand to see their economies devastated. Canada’s conundrum In spite of its large area and vast expanse of Arctic territory, Canada is amongst the countries expected to be most impacted by climate change, both in terms of landscape and economic impact. Notwithstanding this, Canada falls woefully short of its commitments under the Kyoto Protocol. At more than 750 million tonnes of CO2e of GHG emissions annually, Canada exceeds its

Kyoto Protocol target of six percent below 1990 levels by over 30 percent. Canada’s lethargy in instituting a federally-mandated GHG scheme can largely be attributed to political dithering. The current Conservative government aggressively opposes any binding reductions, and blames the previous Liberal government for signing the Kyoto Protocol, but not passing an aggressive climate policy to achieve those aims. The Alberta oil sands contribute more than one-third of Canada’s emissions. Being the main Conservative political stronghold, it was convenient for the Harper government to align with the previous Bush administration and take a position that blamed developing countries like India and China for deadlocked climate talks. However, with the US moving aggressively under Obama’s leadership, Canada risks being left behind, and this could have significant economic impacts in terms of taking advantage of international carbon-trading schemes and the introduction of future carbon taxes on exports from Canada. In the absence of coherent federal di-

Climate Change rection, some Canadian provinces have taken unilateral steps to ensure that they do not miss any potential benefits from the shift to a carbon-constrained economy. The federal plan targets reductions by 2020 and 2050, and aims at channeling significant funds into still-emerging carbon capture and storage (CCS) technologies, while provincial policies, with more immediate impact, have already been introduced. British Columbia, for example, introduced a carbon tax on all fossil fuels, while Quebec and Ontario have started to phase out coal-fired generation. The writing is on the wall. Under significant international pressure and unilateral action by provinces, it is only a matter of time before a more stringent federally-mandated GHG emissionsâ&#x20AC;&#x2122; regime is introduced. While its exact nature is uncertain, it most likely will be some combination of cap and trade, incentives, taxes, and focused funding for clean technologies. The business imperative Globally, businesses are being held responsible for their carbon footprints. This is being driven by one or more of

the following reasons: government-legislated regulations, demands by shareholders to understand the carbon exposure of their investments, and brand and competitive drivers. Cap and trade schemes internalize the cost of emitting to businesses with the option of becoming more efficient and reducing GHGs (with the resultant reward of cost reductions), buying carbon credits to neutralize emissions, or paying a penalty for exceeding their emissionsâ&#x20AC;&#x2122; quotas. Carbon taxes target emissions more directly, as an entity pays a tax on the carbon it emits. While each method has its pros and cons, Canada is on track to introduce a combination of these measures in one form or other. Most carbon-related legislation includes punitive measures for non-compliance, all translatable into increased costs to businesses that are not prepared. The costs of being unprepared are significant. In the UK, the recently introduced Carbon Reduction Commitment (CRC) program will impose stiff penalties for companies that fail to accurately report CO2 emissions by July 2011. The CRC is currently considered the blue-

Climate Change derway. Canadian business needs to get ready for it. Measuring your carbon impact Companies need to take time to understand the impacts of the move to the low-carbon economy on their business, so that they can make better-informed decisions, which will enable them to survive, innovate, adapt, and grow. The first step in building an organization’s carbon management strategy is to figure out what it emits. Building a comprehensive GHG inventory allows for the identification of emission sources, benchmarking against industry/company standards, financial impact analysis, target setting, and tracking progress. This enables the organization to introduce process efficiencies for cost savings and to, potentially, benefit from (future) carbon trading schemes. The six main greenhouse gases are carbon dioxide, methane, nitrous oxide, hydro and perfluoro-hydrocarbons, and sulfur hexafluoride. Although carbon dioxide is the most abundant and the source of greatest concern, all of the other GHGs have a higher intensity than CO2.

Entity-level GHG accounting quantifies and organizes GHG emissions information, based on common standards and protocols. Measuring and tracking GHG emissions can be a complex task, depending on the depth to which the analysis is carried out. This involves several steps, including laying down organizational and operational boundaries, identifying emissions sources and activities, attributing scopes to the emissions, and calculating the emissions from each activity. There are three types of emissions that need to be addressed, referred to as Scope 1, 2 and 3. Scope 1 is generally the direct emissions that result from sources that a company owns or controls; Scope 2 emissions are indirect emissions that result from purchased electricity, heat or steam; Scope 3 includes all other indirect emissions, usually related to upstream value-added chains and downstream product usage. While most companies are concerned about Scope 1 emissions, manufacturers of consumer products, such as refrigerators, for example, will find that the vast majority of their emissions are Scope 3.

It is also sometimes easier for companies to target their Scope 3 emissions for reduction purposes, since these usually do not impact their core business activities. Accounting for carbon offsets and carbon neutrality relates to carbon projects and not to entity level accounting. The World Resources Institute and the World Business Council for Sustainable Development (WRI/WBCSD) were the first to propose specific protocols for GHG measurement at the organizational and project level. This also formed the basis for the evolution of the ISO 14064 standard, which has three parts: • ISO 14064-1 Part 1 specifies principles and requirements at the organization level for the design, development, management, maintenance and verification procedures used to establish and document an organization's GHG inventory. • ISO 14064-2 Part 2 is targeted at the project level and specifies principles and requirements and provides guidance for quantifying and reporting activities intended to achieve GHG emission reductions. • ISO 14064-3 Part 3 specifies prin-

Climate Change ciples and requirements and provides guidance for those conducting or managing the validation and/or verification of GHG assertions, such as the validation or verification of an organization's GHG inventory emissions claim or a project's GHG emission reduction claim. Several carbon programs have their own requirements for both entity and project level accounting and verification. Examples include the Chicago Climate Exchange, Voluntary Carbon Standard (VCS), Gold Standard, California Climate Action Registry, and Regional GHG Initiative (RGGI). While it is important to follow one of the several protocols to build a credible carbon footprint that is acceptable by regulatory authorities and/or reporting programs, the company’s rationale for measuring GHGs can also decide the methodology. For absolute measurement, tonnes per CO 2 equivalent (tCO2e) are required, whereas, for internal tracking and monitoring performance, a company may record tonnes of CO2 per unit of product or per $ of revenue. The Carbon Disclosure Project

(www.cdproject.net), an independent, not-for-profit organization, now holds one of the largest databases of primary corporate climate change information in the world. Thousands of organizations have made the first step towards measuring and disclosing their greenhouse gas emissions and climate change strategies. The way ahead It is becoming abundantly clear that it makes good business sense for Canadian industry to put in place strategies that may include modifications to products, processes and investment patterns to prepare for the low-carbon economy. Several provinces are already following the global trend and making plans to introduce mandatory emissions’ reporting. While the steps involved in developing an effective and credible carbon improvement plan do not generally involve major investment, given the complex nature of the task, GHG assessments require qualified personnel to quantify and verify GHG reports. Further, it is important to have third-party involvement to ensure the credibility of a GHG footprint. The benefits incurred - for example,

competitive differentiation and retention of market share - more than offset any costs incurred. It is also worth noting that, in 2008, clean-tech investments attracted more capital than communications or life sciences. Canadian industry has the capability to respond to these new markets and to be sellers of technology instead of resources. Because Copenhagen has largely been seen as a failure, leadership by companies will be more important than ever. Canada’s Environment Minister has already stated that Canada’s climate policy will be to wait for the US to move and then fall in step. This is hardly the leadership role we would expect. Canada can and must take a more proactive role. Dr. Bernard Fleet is President of Fleetec Inc., and an Adjunct Professor at Ryerson University.

Stormwater Management

The evolution of sustainable stormwater management By Jeff Walker

tormwater management has become an increasingly challenging issue for urban communities. In many cases, rainwater can no longer follow its natural patterns, which increases the volume of runoff, causing many problems. In a natural environment, runoff is minimized since rainfall, for the most part, is dealt with naturally through infiltration, evaporation or plant transpiration. Urbanization, however, increases the amount of impervious surfaces and this in turn increases the percentage of rainfall that becomes runoff. As a result, we are seeing added stress on natural watercourses and related environments, simply because the increased imperviousness reduces the ability for rainfall to be absorbed into the soil, detained or treated. And this is changing the natural water balance. Water balance is an expression of the flow of water in and out of the system, and represents the proportion of precipitation that infiltrates, evapotranspirates, or runs off. If one or more of these elements goes out of its pre-development balance, it generates consequences to the natural system such as increases in volumes, peak flows and durations, temperatures and sediment. Excessive runoff, in particular, can lead to flooding and altered stream flow, erosion, algae growth, compromised water quality, threats to aquatic habitat, and changes to groundwater resources. Managing the water balance is important for flood protection, sustaining water quality, erosion control, and improving infiltration. Today, there is a growing need to implement stormwater management systems that control the volume and quality of runoff by other than traditional pipebased means. A low impact approach, using landscaping and other onsite techniques to mimic pre-development conditions, will be especially critical. Evolution of stormwater practices In order to understand what is needed today, it is important to look at the evolution of stormwater practices over the years. Prior to the 1990s, the major focus 64 | January 2010

was simply on controlling quantity. This prompted widespread installation of piped drainage systems that were designed to convey the runoff to downstream watercourses as quickly as possible. In the early 1990s, the focus expanded to include water quality and erosion. At this juncture, we saw the early iterations of ponds as a stormwater measure. Today, it is the treatment of stormwater that has come under the spotlight, as concern grows about protecting fisheries, preserving stream morphology, and protecting groundwater resources. Stormwater management objectives are now being accomplished through a variety of source and conveyance control measures that more closely simulate conditions prior to development. There are a number of these measures in use today, including: • Attenuation techniques that slow the release rate of stored water. • Infiltration processes for recharging groundwater. • Filtration systems for improving water quality. • Phyto-remediation to remove contaminants using plant material processes. These source and conveyance measures do not preclude the use of traditional end-of-pipe approaches, which continue

to be a factor in stormwater planning. Rather, the objective of these measures is to minimize and treat runoff before it reaches the end-of-pipe elements. The “treatment train” None of the sustainable stormwater measures working independently will address all the runoff issues we face today. Rather, the ideal way is the implementation of a series of solutions, often called the “treatment train” approach (Figure 1). Selecting the right combination of solutions for a specific application is very much dependent on location, project parameters, and costs. When assessing choices, one of the first things to look at is site conditions, such as soil, topography, and proximity to fisheries habitats, wells, and hazardous land uses. Climatic conditions, including rainfall and winter conditions, must be considered as well. The Water Balance Model powered by QUALHYMO provides a decision support tool that can assist the analysis process. (www.waterbalance.ca) It is also important to understand the pre- and post-development conditions and the relative change to the imperviousness or characteristics of the runoff. For instance, not all runoff is the same; runoff from different sources can experience different levels of contamination.

Stormwater Management Techniques for stormwater management Some techniques that can be used in stormwater systems include bioretention, green roofs, soakaway pits, swales, filter strips, and permeable pavement. While this is by no means a complete list of all available alternatives, it provides an indication of the various options that can be used to address specific objectives. There are many good sources of information about these techniques, such as the Low Impact Development Stormwater Management Manual from Credit Valley Conservation Authority and Toronto and Region Conservation Authority. Another good source is the Metro Vancouver Stormwater Source Design Guidelines. Collaboration needed While the low impact stormwater approach appears to be an effective solution, implementation to date in Canada has been slow and sporadic. This is, in large part, because those in charge of water management services tend to adhere to more familiar and entrenched practices. Adding to the challenge is the fact that low impact measures require an integrated decentralized approach, where sustainable techniques may have to be installed in a combination of residential properties, parking lots, roads, parks, etc., under both public and private ownership and/or control. This is unlike traditional stormwater management which is primarily a single system, owned and maintained by the municipality. Even within municipalities, solutions need to cross organizational boundaries. For example, a set of measures may require the approval or involvement of multiple departments, including planning, water services, building, environmental, transportation, parks, and communications – not to mention external agencies. Each plays a role, and each requires a level of knowledge, expertise and commitment. Despite the challenges, studies have proven that costs can be lower with a properly designed and constructed system. By closing the knowledge gap in terms of understanding the available techniques and applications, as well as individual roles and job functions, we can expect to gain real and sustainable benefits from working towards common goals. www.esemag.com

Figure 1 – Examples of the Treatment Train Approach to Stormwater Management.

The Canadian Standards Association has actively consulted with leading stormwater management experts, representing municipalities, consultants, developers and researchers. As part of this initiative, it has now developed a series of stormwater management courses that are designed to close the knowledge gap and provide greater insight into the is-

sues, options and application of appropriate stormwater solutions. For information on course dates, locations and descriptions, visit www. csa.ca/infrastructure. Jeff Walker is with the Canadian Standards Association. E-mail: michael.loreto@csagroup.org

PCBs and Groundwater

Removing PCBs from groundwater with activated carbon By Jeff Marmarelli and John Sherbondy

or about 50 years, polychlorinated biphenyls (PCBs) were commonly used in industrial materials, including caulking, cutting oils, inks, paints, and as dielectric fluids in electrical equipment such as transformers and capacitors. Concerns over health effects led to a North American ban on manufacturing PCBs in 1977. By the mid-1980s, an initiative was under way to clean up contaminated areas and phase out PCB-containing equipment and products that were still in use. This clean-up effort continues today. Careless disposal practices and accidental discharges in the past contribute to the current level of PCBs in groundwater and in sediments of rivers and lakes. Growing public and government concern about health hazards has led to new practices for safely removing and disposing of PCBs. Residual contamination has been effectively treated with systems utilizing activated carbon adsorption media. Activated carbon is widely used for the adsorption of many contaminants in liquid and air streams. It is produced from carbonaceous organic substances, including bituminous coal, coconut shell, lignite, bone, wood and other materials. Its many applications include the production of foods, decolorization of liquids, as for the recycling of glycol, and trace contamination removal from air. Adsorption results from a physical process in which layers of atoms or molecules of one substance are attracted onto the surface structure of another substance. The extensive pore structure of activated carbon provides an extremely high surface area, which makes it an ideal adsorbent. One pound of activated carbon has a surface area equivalent to six football fields. Activated carbon exhibits a graphitic plate structure, and the formation of adsorption surfaces can be likened to a box of peanut brittle, with the highest-energy adsorption sites formed at the intersections of the plates (Figure 1). The iodine number is used as a general measurement of the surface area of the activated car66 | January 2010

Figure 1. The formation of adsorption surfaces can be likened to a box of peanut brittle, with the highest-energy adsorption sites formed at the intersections of the plates.

bon. These numbers generally range from 900 to 1,100 for higher-quality carbons. Activated carbons tend to adsorb organic compounds with increasing affinity as the molecular weight, boiling point and refractive index of the adsorbate (the material being adsorbed) increase, and as solubility decreases. Thus, activated carbon has a high affinity for PCBs due to their high molecular weight, high indices of refraction, and very low solubilities. PCBs have a very large molecular structure and, for effective adsorption, will require an activated carbon with a compatible pore size. Different base materials will yield different pore structures. For example, coal-based carbon has a pore structure that will better accommodate these types of molecules than coconut-based carbon. Coconutbased carbons are more suited to smaller molecular weight compounds with low boiling points, and, therefore, are not as

effective in this application as a goodquality coal-based carbon. The surface loading of adsorbate on activated carbon varies with the concentration and conditions in the fluid stream. In order to evaluate the economic potential of an application, the activated carbon isotherms can be developed for the particular compound at a given set of conditions. Many isotherms are already available for various compounds, including PCBs. They can be obtained from carbon manufacturers, purification companies and EPA literature, and can also be developed in the lab using simple procedures. Figure 2 illustrates an isotherm for a PCB molecule with one chlorine atom on TIGG 5D 1240 coal-based activated carbon. As with any testing, these isotherms are performed under controlled laboratory conditions. Actual performance in the field can be affected by continued on page 114...

Instrumentation

Improving wastewater treatment with air flow instrumentation By Steve Craig

n wastewater treatment plants, various processes are used to eliminate organic pollutants. One of the most common processes is the activated sludge method, which biologically treats wastewater in large aeration basins. This process requires compressed air to be pumped into the aeration basins, where a diffuser system ensures the air is distributed evenly, for optimum treatment. Large amounts of compressed air are required to ensure this process operates effectively to treat wastewater adequately, before it can be moved along to clarifying basins, filtering, disinfection, and other treatment processes. Controlling the proper amount of air released into the aeration basins is essential because the air flow controls the growth of microorganisms. Flow meters are typically installed in the aeration system piping to measure the amount of air flow and the metersâ&#x20AC;&#x2122; analog or digital outputs run to the plantâ&#x20AC;&#x2122;s control system.

In wastewater facilities, as well as industrial plants, air compressor operation is one of the largest energy expenses. The cost of energy to produce compressed air continues to rise, along with fuel costs, so optimizing the aeration process by measuring and controlling the aeration systemâ&#x20AC;&#x2122;s air flow with a suitable flow meter also reduces energy costs. In most plants, each of several aeration basins is configured with numerous diffuser systems. Individual air flow monitoring and independent control is generally required for each diffuser system. The compressor system must run 24/7 to maintain the optimum amount of air flowing to the diffuser systems and the aeration basins. However, the demand for air changes throughout the day to accommodate a variety of climatic and other factors. In evaluating and selecting flow meters, there are five important factors to consider:

1. Flow sensor technology. 2. Range and accuracy. 3. Operating environment. 4. Ease of installation. 5. Maintenance and lifecycle. 1. Flow sensor technology - Three flow sensor technologies have typically been in use in aeration air flow monitoring applications in wastewater treatment plants: differential pressure (orifice plates), vortex shedding, and thermal dispersion (mass flow). Differential pressure and, to a limited degree, vortex shedding technologies have an installed base. While orifice plates have been in use for many decades in water treatment plants, and vortex shedding is recognized for its high accuracy, thermal dispersion flow measurement now has the largest installed base for this application. It offers direct mass flow measurement and a wider turndown ratio, has no holes or moving parts to foul or clog, is an insertion-style meter

Instrumentation that installs in a single tap, and is costeffective. 2. Accuracy and flow range - At a typical large urban municipal wastewater treatment plant, one of the more common specifications for the aeration flow meter is to measure over a wide flow range from 1.5 to 150 standard feet per second (0.46 to 46 normal metre per second), with an accuracy of +2% of reading, +0.5% of full scale, with a repeatability of +0.5% of reading. Most aeration systems will operate with excellent efficiency at this level of accuracy. Flow meter manufacturers can provide products for higher accuracy specifications, but these products typically include extra features and functions that are unused in aeration applications, and they carry a price premium. It is also critically important to look at a flow meter’s repeatability specification, which tells the user how reliably the device will maintain its specified accuracy level. 3. Operating environment - The amount of air required to maintain the treatment process varies throughout the day and de-

pends on environmental and climate conditions. Flow meters for such applications must be able to tolerate significant drops in pressure throughout the system, from 0.8 to 17.6 psig (0.6 to 1.2 bar [g]). This means that the flow meter must have a wide turndown range, which can be a problem for mechanical devices with moving parts that wear over time.

Temperatures can vary widely from –68°F to 150°F (–20°C to +65°C). This is also a rugged, dirty environment that can be a maintenance issue with devices with holes that may plug or foul. 4.

straight-run needed to ensure the flow meter is measuring accurately. Tabbed-type flow conditioners have proved successful in these applications. Other flow conditioning technology choices, including tube bundles, honeycombs and perforated plates, may also be considered, depending upon the specifics of the application and obstructions. 5. Maintenance and lifecycle - Be sure to ask about the maintenance requirements for your flow meter. Some flow meters need more frequent recalibration and/or cleaning, which can be time-consuming or, worse, require you to remove the meter from service. For wastewater aeration applications, the ideal flow meter will have no moving parts to wear out and no routine cleaning requirements, to minimize maintenance cost and provide many years of service. When calculating the cost of a new flow meter, be sure to look beyond the purchase price to determine what it will cost to maintain and how long it will provide service.

Instrumentation wastewater treatment operations depends on a number of major variables. These include the plant’s physical climate, the layout, the volume of waste, the equipment in use (including the diffuser, compressor and control system), the piping configuration, the flow instrumentation, and the energy supplier. In a perfect world, all of these variable factors would work together to promote the optimum microorganism growth rate needed to treat the wastewater in the shortest amount of time. While perfection is beyond most of us, improvement is possible and valuable. If your energy costs seem high, consider all the variables, including the type of flow meters, where they are placed in the pipeline, and their calibration for your application. Selecting the wrong type of flow meter, or improper calibration or installation, can all result in less than optimum compressor efficiency and higher energy costs. To determine the potential savings, consider the amount of compressed air consumed daily, and then look at what a small percentage improvement in com-

pressor efficiency is worth. Then ask your flow meter supplier to help you review the performance of the instrument in the actual application.

Outfitting wastewater treatment aeration systems with the proper flow meter will result in improved process effectiveness and reduced energy consumption. Choosing the right flow meter Outfitting wastewater treatment aeration systems with the proper flow meter will result in improved process effectiveness and reduced energy consumption. Looking carefully at measuring accuracy and range needs, installation conditions

and complexity, and maintenance requirements, will result in selecting the most cost-effective flow metering solution. Over the past three years, a number of flow meters from multiple manufacturers have been developed for use in wastewater treatment facilities. When you are evaluating flow meters for your next project, be sure to look beyond accuracy, which, while important, can be misleading in terms of overall performance, reliability and low lifecycle costs. You can also avoid a lot of headaches if you ask about how well the flow meter will operate within your specific environment. Don’t forget to consider the ease of installation and think ahead about maintenance. To evaluate your true total investment cost, look beyond the initial cash outlay to include the cost of operating your next flow meter over its lifecycle.

PCBs and Groundwater

Removing PCBs from groundwater with activated carbon ... con’t from page 66 any number of factors associated with the treatment system. When dealing with PCB-contaminated groundwater, the solubility of the PCB isomer molecules in the water can typically range from 20 to 60 ppb, with solubilities generally below 1 ppm. Above these levels, the PCBs will be found as free product. As illustrated by the isotherm, PCBs are readily adsorbed by activated carbon, with the example of the PCB isomer with only one chlorine atom (the lowest affinity for all PCB isomers) showing excellent loading on the carbon, even at 1 ppb levels. The result is that effluent levels below 1 ppb are achievable. Designing the carbon bed Treatment of PCB-contaminated water is dependent not only on keeping the carbon “clean” for proper kinetic transference of the molecules, but also on the contact time allowed for adsorption to take place. Field experience has shown that, often under turbid conditions, PCB levels in the effluent after the carbon adsorbers can be as high as 3 - 5 ppb. The reason for these higher-than-expected levels in the effluent is that the PCBs will attach themselves to colloidal material in the water, or any carbon fines, and pass through the bed without being adsorbed. In order to decrease these residual levels upstream and 114 | January 2010

downstream, filtration is required. Typically a 5 - 10 micron bag filter is installed prior to the carbon bed, and a 0.5 micron bag filter is installed after the carbon bed, prior to discharge. These processes remove most suspended solids that may be entering the carbon and essentially “plugging” the bed of the carbon, thus limiting adsorption. Also, any solids that may be making their way through to the effluent are captured. In addition to the pre- and post-filtration, the carbon bed needs to be properly sized. Both the bed surface area and the carbon-bed depth affect removal efficiency. About seven to eight minutes empty-bed contact time (EBCT, or time to pass fluid through a given actual volume of carbon present as a theoretically open volume) is optimal for proper adsorption. Typically, a minimum of three feet of carbon-bed depth is required and the

surface area is designed to promote a superficial velocity of four to six gallons per minute per square foot. Slower velocities can be used, but very low velocities should be avoided as this may promote the occurrence of channeling, or the liquid seeking a path of least resistance through the carbon bed, resulting in poor distribution (Figure 3). Overall, activated carbon adsorption is an effective way of reducing PCB contamination in groundwater. Successful results can be achieved with a properly designed system that addresses both pre-filtration and post-filtration, along with proper carbon selection and bed design parameters, including bed surface area, depth, and contact time.
