He said the productivity of Ontarians was ahead of both Germany and Japan and the future of the environmental industry was very bright. He presented Dr. Andrew Benedek, of Zenon Environmental, with a

While premier Rae gave an impressive performance that morning, the provincial auditor appeared underwhelmed. Later that very day, he blasted the environment min istry. While the media ignored the premier's speech,they focussed on the auditor's warn ing that scores of Ontario water and wastewater treatment plants had not been adequately tested or were not in compliance with MGEE regulations.

tal laboratory industry consists of approxi mately 100 companies with annual revenues of $100 million. Whilst the numbers ap pear small in the context of an $8 billion total environment industry, they are none theless significant. We are as important to Canada's billion dollar environmental in

dustry as gasoline is to the automotive in dustry. Without good, high quality environ mental data Canada would not have an en

vironmental industry. Our association, which represents the environmental laboratory testing industry in Canada, is not asking governments for hand outs or subsidies. It simply wants actions which recognize our sector as a player in the realization of Canada's full economic

potential. Our sector needs to be recognized and supported by governments as a signifi cant part of the "New Economy" in their pursuit of industrial policies for environ mental industries. This is simply not hap pening. The current business climate

Let me provide you with a brief tour of the economic policy climate for a business person contemplating investing in Canada's laboratory sector, or alternatively, the op portunities for a young science graduate from our universities who might be think ing of a long-term career in some labora tory specialization. â&#x20AC;˘ First, and most damaging, no comprehen sive policy exists within Canadian govern ments for the economic development of the private analytical laboratory sector. Labo ratory testing and high data quality stand ards are not properly recognized by govern ments as a fundamental component of a knowledge-based society. â&#x20AC;˘ Secondly, the economic potential of our sector is taken for granted, or even ignored by governments. The subject has not, to the best of my knowledge, been discussed by the Canadian Council of Environment Min

isters, nor by federal-provincial Ministers *MDS Environmental Services Limited and

Chairman, International Association of EnvironmentalTesting Laboratories

- Canada. Excerpted from his paper given at the Environment & Energy Conference of Ontario, November, 1994 32

of Trade and Industry. â&#x20AC;˘ Thirdly, fiscal restraint, and a lack of uni fied policy for private sector laboratory de velopment, are driving government labora tories into subsidized competition with the private sector laboratories. This inflicts commercial damage on private investments by restricting market-place access and, in many instances, by taking away their cus tomers. This phenomenon has spread from coast to coast as a substitute for efficient

management practices. The old argument that government labs somehow provide superior data is refuted by the fact that governments at all levels are losing environmental court decisions because of poor government lab data. lAETL contends that Canadian govern ments have moved too slowly in recogniz ing the need for a fundamental restructur ing of their roles, responsibilities and in vestments in laboratory capital stock. Gov ernment actions,from the perspective of the environmental testing industry, have been unfocused. The market-place oriented "in dustry" consists of both private and public sector laboratories. The absence of govern ment leadership to meet the urgent need for "industry-wide" restructuring is disturbing to those of us who manage investments in the private sector. lAETL believes that, if governments were to practice effective industrial consul tation, they would access at no cost, a rea sonable array of solutions to their fiscal and management challenges in public sector laboratories. The corollary of this is that we in the private sector would have a greater sense of assurance when we invest in ex

pensive equipment and hire and train new staff.

The recent summary report on local com munity consultation, by Dr. Jon Gerrard, Secretary of State (Science, Research and Development) is laudable in its recognition that some federal labs are competing with the private sector. IAETL supports his rec ommendation to de-emphasize data collec tion, which can be done commercially. lAETL's six-point program for CCME 1. The private laboratory sector, Canadawide, requires a higher level of govemment recognition of the economic potential of

2. A significant improvement is needed in the processes for public/private sector con sultation and program harmonization for environmental laboratory services. These processes should be designed to support the industry's long-term economic and scientific development and improve the availability of efficient, low-cost, high-quality labora tory services for customers in domestic and foreign markets. lAETL believes that gov emment labs have an important role -a mar ket niche - just as commercial labs do. However, we need more consultation and

cooperation, not more competition. 3. The sector needs govemment policies and programs which provide a harmonized and efficient complementary relationship be tween the private and public sector labora tory systems in Canada. For example, gov emment labs could take charge of environ mental analytical research. 4. The laboratory industry requires a sup portive legislative and regulatory framework designed to encourage its long-term eco nomic development and to ensure world class standards of quality and service. 5. Govemments at all levels should recog nize that it is in the interests of the public, the national economy and the industry that operational efficiency and lower costs be realized in public sector laboratories through alternate delivery mechanisms, including higher levels of privatization and out sourcing. 6. All levels of government should support the exclusive use of CAEAI7SCC accred ited laboratories. Accreditation should be

promoted and assured by govemment labo ratories.

At the present time, the two sectors are moving towards a situation of increased competition and the loser will be the pub lic, the taxpayers, the customers, the em ployees and the private sector shareholders. We are, therefore, recommending, strongly, that these six issues be taken up by the fed eral and provincial govemments through the Canadian Council of Environment Minis

ters. We believe that these issues will help in the federal govemment's efforts of har monization. We would like to see working groups established, with industry participa tion, that are charged with bringing recom mendations to Ministers for joint action. We would also like to see a proper monitoring and follow-up process to the decisions of Ministers in this area.

The integration of environmental and industrial policy is not a trivial issue, ft involves jobs, growth and the harmoniza tion of intergovernmental policies and pro grams. These are key issues for our times. For more information,

Consultants and Metro Toronto launch TIP

Anew consortium which combines

the expertise and resources of

consultants with that of MetroToronto was launched Oct.6 as

the Toronto International Partnership (TIP). A Gore & Storrie VP, Norm Huggins has been working as Interim Chair for the past few months. At the official launching cer emony at Metro Hall, he outlined the op portunities and latent talent in TIP. A little more than a year ago, Metro To ronto's Economic Development Division (EDD) recognized the growing demand for urban infrastructure, especially in develop ing nations. It also recognized that Cana dian firms in general and Metro-area firms in particular are missing out because, by and large,they are small by world standards,have no permanent presence in foreign markets; nor do they enjoy government support for marketing efforts, as do many foreign firms. In response, the EDD proposed to Metro Council that a joint venture be mounted that would seek to overcome these challenges. In a report to council last February, the di vision noted that Metro is "well-positioned to work with a group of qualified consult ing firms" because both EDD and several of Metro's operating departments have wide networks of intemational contacts and "the

participation and support of Metropolitan Toronto as a respected urban municipality would offer significant advantages to a re gional group of companies involved in de veloping urban infrastructure." Metro Council agreed and, after several months of development work, approved its

formal participation in TIP on June 15. It is the form of Metro's participation that makes TIP unique. Cooperation between government and industry to develop inter national trading opportunities is nothing new, but we do not know of another joint venture in which a government's operating departments are involved as full and equal partners.

ENGINEERING PROFESSOR

In marketing terms, TIP has not one but three unique selling propositions: 1. It includes a private sector that has de signed and built an impressive infrastruc ture system in an environmentally respon sible way. 2. It includes a local government that oper ates the system efficiently and effectively. 3. It comes from a community that is pre pared to do business with the world.

The University of Gueiph invites appiications for a fuii-time tenure-track position commencing July 1, 1995 in its School of Engineering. The School of Engineering has 19 faculty members, 16 staff members, and approx imately 500 undergraduate students (40% of whom are female) and about 100

graduate students.The School offers accredited undergraduate programs in engineering systems and computing, environmental engineering, biological engineering, food engineering, and water resources engineering.

Norm Huggins said,"in marketing TIP's capabilities, we will emphasize that our public and private sector partners, with their combined expertise in urban/municipal in frastructure design, construction and opera tions, can provide one-stop shopping for intemational infrastructure buyers." Specifically,there are three parts to TIP's strategic plan: I. TIP will offer internationally experienced project teams that can provide single source expertise for the project management, de sign, constmction, operation and some fi nancial elements of infrastructure facilities.

"During that time," said Mr. Huggins," we have discovered there is a great interna tional interest in what we are doing, and, in

ro's creation, the success of its urban infra

structure projects, and the large scale of its operations are powerful tools in showcasing tip's ability to solve similar problems in other parts of the world. 3. TIP will assemble project teams or con sortia that meet the specific requirements of each potential client. There are some 3,000 engineering staff employed by TIP member companies, plus the human re sources of Metro Toronto's operating depart ments. This Is an impressive pool of exper tise from which to draw.

Once a decision is made to

Groundwater remediation ous acid forms few salts, which makes it

difficult to remove by precipitation or fil tration. However, many salts are formed

by arsenic acid (H.AsO^), which is the form in which As(V) is present. The oxidation of arsenious acid to ar

senic acid can be represented by several reactions, depending on pH. At typical groundwater pH of 6.5-8.5, the only reac tions of concern include:

Based on previous experience with similar technology for manganese and iron removal, the performance of Filtronics Electromedia does not change over time, and pilot performance is an accurate predictor of full scale performance.

Research, 32 of 36 target VOCs were ob served in at least one off-gas sample from the plants studied. Chlorinated VOCs tended to be stripped to a greater extent than nonchlorinated compounds. The data ob tained by J. Bell and coworkers suggest that VOC stripping can be reduced by reducing aeration rates, and that operating and de sign parameters have an impact on the loss of VOCs.

The results, reported in Environmental Technology, indicate that the percentage utilization of carbohydrates, pro teins and lipids in primary sludge is signifi cantly affected by variations in HRT and pH. Changes in SRT influence only protein dis similation.

A primary treatment process was recom mended with chemical addition of alum or

ferric chloride to enhance settling. Some 22 kilometres of gravity collector sewer have been completed and the final two kilometres are under construction. All

wastewater flows by gravity to the Main Pumping Station in Riverview, which was completed in 1989. The 272,000 mVd pumping station is 21 metres in diameter and 39 metres deep, said Project Director, Boyd Touchie. Below grade, the depth is equivalent to the height of a nine-storey building, he said, adding the total capital cost for the collector sys tem will be $40 million.

He said the first phase of the 1 15,000 cubic metres per day Wastewater Treatment Facility was completed in 1991. This phase included a forcemain to the Inlet Building where pre-treatment (screening and grit re moval) is carried out. A primary settling tank, 39 metres in diameter, was completed and also an un derground tunnel system including a Sludge Pumping Gallery. He said this system was used to complete pilot studies to finalize the most "efficient and economical" treatment process.

Touchie said the Commission purchased three sludge dewatering centrifuges which were installed by the general contractor. Dewatered sludge is stabilized by mix ing it with lime to produce biosolids. The

Electrolytic chlorination for zebra mussels

Greenwood Environmental Inc. is the co-developer and

licensee of an electrolytic system for the eradication of zebra mussels in fresh water. The system utilizes elec trolysis of chloride ions, which are naturally present in fresh wa ter, to chlorine gas byproducts which are toxic to zebra mussels. Greenwood says its electrolytic chlorination system advances the practical application of electrolysis in fresh water by generat ing sufficient chlorine at its needed location, without the addition of chemicals, and at a competitive cost, to achieve the effective

not around it. Direct current power is supplied from a rectifier. A timed polarity reversing switch is integrated with the power circuit to provide intermittent polarity reversal which prevents deposition of scale on the electrolytic cell. The electrolytic cell is tapped into the intake pipe at a location convenient to a power supply and easily accessible for inspection and maintenance. Natural water, containing chloride ions, passes through the elec trode configuration. Electrolysis occurs at the electrode surfaces, producing chlorine gas, hydrogen, and oxygen. A significant por

opment has determined that intermittent dosages of chlorine at concentrations as low as 0.5 parts per million, measured as total residual chlorine (TRC), will perform this task. Greenwood says its system generates 5.0 to 7.0 ppm TRC from fresh Great Lakes water with a chloride concentration of 14-17 ppm. A TRC con centration of 7 ppm is similar to concentrations found in munici pal drinking water. The electrolytic eel 1 uniquely improves upon prior electrolytic technology in its ability to use natural chloride ions present in the fresh intake water. Prior electrolytic technology was limited to tlow-through aqueous chlorination from naturally saline or artifi cially salinated water because the systems available needed the corresponding minimum levels of electrolyte conductivity to op erate at an economical rate of electric power consumption. The Greenwood system is said to provide improved power utilization efficiency with much lower conductivity fresh water. The electrolytic cell is contained within a housing between

environment as natural intake chloride is converted to chlorine,

then eventually reverts back to chloride, producing effluent not appreciably different in chlorine or chloride concentration than the original intake water. Sulphur based dechlorination methods are applied where residence time is insufficient for the chlorine to revert to chloride.

The electrolytic cell is designed to substantially improve upon the safety of operation and the capital costs of competing proc esses. To overcome the disadvantage of processing fresh water with low conductivity (<300 uMHOS/cm) and incurring exces sive use of electrical power, with safety and cost penalties, sev eral proprietary elements of invention are utilized which, in com bination, provide the result of cost effective performance in fresh water. In a preferred embodiment, the cell anodes and cathodes are fabricated from material that enables rapid pole reversal switching to reduce cathodic depositions from fresh water miner als (such as calcium) and, by using dimensionally stable mate rial, the invention allows no cathodic metallic ions, which are

generally found to be pollutants, to discharge into the fresh wa

Another interesting variation with the Australian system is the concept of "Type Testing".

In the City of Melboume in the State of Victoria, the Melbourne Water Board has

recently changed its method of conducting plumbing inspections. More emphasis is being placed on the contractor completing a "Certificate of Compliance", verifying that he has installed the piping system within the requirements set down by Australian Standards and Melboume Water. This sys tem has now reduced the number of plumb ing inspections required to be completed on a project. Intermediate inspections are no longer required for: Under slab wastes and drains; wastes, soil and vent pipes; above ground drains; pressure lines; hot or cold water installations; and below ground wa ter services.

Once work has been completed, licensed persons must complete a "Certificate of Compliance" which acts as a guarantee for the work carried out. A Certification of

Compliance is very comprehensive and will place great accountability on the licensed person for the quality of work undertaken. It will set aside the quality and accuracy of "as completed" diagrams.

EUROPE

In Europe,several countries have already written some standards for backflow pre vention devices. France and Italy have ex isting, and very similar, performance stand ards for the reduced pressure principle de vice. As part of the European Unification Program, there is a system of establishing European standards or CEN documents to cover standardized requirements for backflow preventers and other plumbing items for all countries in Europe. It should be stressed, however,that even though there is a written agreement to write these stand ards, they still have to be accepted by each individual country once written. There are currently a number of committees working

Site remediation

The impact of soil toxiclty testing on bioremediation technoiogy carbons can be achieved by the addition of solid-phase, biodegradable, organic amend ments that have been prepared to have soilspecific properties including particle size distribution, nutrient profile, and nutrient release kinetics (Seech et ai, 1993). The technology is known as Daramendâ&#x201E;˘ bioremediation.

Extensive laboratory studies and fieldscale demonstrations have indicated that this

Measuresare being taken by En

vironment Canada and the

Ontario Ministry of Environ ment and Energy (MGEE) to establish soil toxiclty testing protocols that will be used in ecological risk assessments of sites contaminated with toxic organic compounds (Wren, et ai, 1993). The ulti mate goal is the establishment of environ mental regulations that will govern soil remediation criteria on the basis of site-spe cific ecological risk. At present, remediation criteria are based mainly on concentrations of specific chemicals in soil. The biologi cal availability of those chemical contami nants is, for the most part, not considered. Reducing concentrations of toxic organic compounds in soil to below established cri teria does not ensure that the soil will be

non-toxic to organisms(plants, animals, and microorganisms) that inhabit the soil.

In addition to the ecologically undesir able consequences that it may cause, high soil toxicity can also limit the effectiveness

of soil remediation technologies, such as bioremediation. Toxicity attributable to some soil contaminants can be high enough to hinder microbiological activity, thereby

technology is applicable to a wide range of soils, including those containing high con centrations of chlorophenols (e.g. 2170 mg PCP/kg) and PAHs (e.g. 18,500 mg/kg). Using the bioremediation technology, the chlorophenol concentration in soil at an in dustrial wood preserving site in Canada was reduced from 702 mg/kg to 4 mg/kg. This is below the current Canadian Council of

Ministers of the Environment (CCME, 1991) interim criteria for industrial soil (5 mg chlorophenols/kg). The total PAH con centration in the same soil was reduced from

1442 mg/kg to 36 mg/kg. Concentrations

of all regulated PAH isomers, including those of high molecular weight, were re duced to below the current CCME criteria for industrial soil. The influence of the bioremediation tech

nology on the toxicity of the soil at the wood

preserving site was evaluated using three separate bioassays (Microtox'"; earthworm mortality; and seed germination). These toxicological bioassays measure the effect of the biologically available fraction of the

position, binding characteristics, and mois ture content, make comparisons of the ac tual sample toxicity results with those of some type of"standard" or "reference" soil difficult. "Standard" soils are used in earth

worm mortality and seed germination bioassays mainly to test the viability of the organisms involved. TheMicrotox bioassay uses a standard liquid media for the same purpose, as is later explained. The impor tance of the toxicity result, therefore, is not the value of the result itself, but the rela

tive difference in magnitude between the initial result (i.e. before remediation) and the final result (i.e. after remediation). A relative increase in the value of the result

will represent an effective reduction in soil

toxicity as measured by a particular bioassay. Comparisons to "standard" soils are valuable in that they ensure that organ ism viability is not a factor in the determi nation of toxicity. A high degree of similar ity between the sample result and the "standard" soil result is a good indication that the sample is non-toxic, as measured by a particular bioassay. Microtox'" (Bulich, 1984) is a bacterial bioassay that measures the toxic effect of a sample on a population of bioluminescent photobacteria. They emit light as a result of respiration. A co-substrate in the enzymatic reaction responsible for the lu minescence is linked to the electron trans

port chain of the bacteria. As such, light emission by the bacteria is directly linked

As is the case with most soil toxicity bioassays, the high degree of variability between soils with respect to such factors as particle size distribution, particle com

have indicated that some soils containing more than approximately 300-400 mg pentachlorophenol/kg, which is used in the wood preserving industry, may be too toxic for direct bioremediation.

Toxic metabolic products, resulting from the partial biodegradation of soil contami

nants, are also of concern as they can accu mulate and detrimentally affect the bioremediation process. The successful remediation of a contaminated site using bioremediation technology may very well depend on the ability of the technology to reduce soil toxicity.

The earthworm mortality bioassay was conducted according to the OECD (1990) test method. It involved exposing common Night Crawlers or Dew Worms (L. terrestris), which are prevalent in the Ca nadian environment, to soil and monitoring their survival over time. Exposure was ex tended to a period of 28 days as it is the prevailing opinion of the scientific commu nity that the recommended period of 14 days is inadequate. A standard Brookston Clay soil was used as a reference because of its

similarity to the soil being tested. Results (Figure 1) indicate complete survival of earthworms in the bioremediated

soil. No mortality (0%), or obvious signs of stress were visible after 7, 14, 21 or 28 days of exposure. Complete earthworm mortality (100%) was observed within four days ofexposure to the untreated soil. There was no significant difference found between "Grace Dearborn Inc.,

The world's need for wood, cont'd. The world's wood supply still conies mostly from the world's remaining natural forest resources. These forests may, or may not, have been utilized before. They may also be regenerated after harvest (maybe many times),or they may be sites which have returned to forest cover after being cleared and used for agriculture for many years. The remaining, mostly undisturbed, natural forests of the world are under in

creasing pressures: First, as a source for wood to supply to an ever increasing demand (the result of the population explosion), and secondly, for conservation as the natural habitat for the world's remaining, but often vulnerable bio-diversity. Tbe conflict be tween these two competing, and possibly in compatible, pressures is certain to intensify. PLANTATIONS ARE ONLY A PARTIAL SOLUTION

Planted forests (plantations) now cover about 100 million ha and currently supply about 10% of the world's industrial wood

supply (about 120 million m- per year). However, most(85%)of the ptanted forests are slow growing - that is growing on aver age less than a third as fast as plantation radiata pine in New Zealand. Where fast growing species have been planted, two thirds have been established as pulpwood crops. It is, therefore, not surprising that plantations currently supply less than 5% of the world's saw and peeler logs (about 45 million m' per year).

Very few tree species which demonstrate potential in nature, or in limited stand man agement, prove, in practice, to be suitable for large scale plantation forestry. Most of those that are successful, especially the pines and eucalypts, are often vigorously opposed by some environmental groups be cause they are considered unnatural and environmentally unacceptable. But without suitable forests planted pri marily for wood production where else will the wortd be able to obtain its wood supplies? PLANTATIONS REQUIRE BOTH TIME AND MONEY Planted forests are not a short term so

lution. Even with radiata pine (one of the few tree species of the world capable of sus taining growth rates of 20 mVhectare/year) it stitl takes 25 to 30 years to grow sawlogs. Many promising plantation tree species take twice as long, or longer, to mature. A ma jor planting effort now,even with fast grow ing species, would not be available for sawlog harvest until the year 2020 or be yond. Plantation forests require a huge capital investment.

alternative may be to use waste wood prod ucts either directly for energy production or for the manufacture of alternative products (e.g. insulation). Another solution is to greatly increase the substitution of wood by metal, cement or plastics. Such a move would certainly reduce the pressure on the world's forests but it may have a much greater impact on the global environment. All wood substitutes are massive energy demanders, e.g. a product in aluminum requires 50 times as much energy as the same product made in wood.

major environmental groups are opposed to plantations of the few successful pine or eucalypt species. Unless there is a major breakthrough in the provision of an alternative and environ mentally acceptable energy source, large scale substitution of wood is not an option. Reducing the world population growth by democratic means is most likely to be achieved by improving general standards of living. But that is only achievable by in creasing the supply of wood products or

ergy demand. In the short term, the only way of increasing the supply of energy is by the greater consumption of fossil fuels. CONCLUSIONS

The existing world forest resource is, in all probability, not capable of sustaining an increased demand for wood without major compromise of the need to protect all the remaining biodiversity on Earth. The plantation resource is too small, too young and mostly too slow growing to do anything more than provide minimal sup plies, especially for the saw and peeler log

wood substitutes. Such moves would re

quire some environmental compromises.

Although it is probably already too late, the plantation solution will require an ur gent and massive investment on a global scale. It will also require a rethink by some influential and global environmental groups. The dilemmas are obvious. Most of the solutions involve some environmental com

promise. Urgent and major financing by the north (the wealthier countries) of plantations in suitable southern countries (the poorer economies) is probably the only practical and feasible solution.

to comply with the Occupational Health and Safety Act and its regulations.

The Occupational Health and Safety Act and regulations do not attempt to tell any

whether or not the downsizing and corpo

organization how it ought to be structured to comply. There is no requirement for a

certain number of managers in any particu lar department. There is no restriction on placing additional obligations and duties on workers in the legislation. Therefore, no

legal restriction exists on a company's abil ity to downsize and re-structure its organi zational make-up that would be in direct conflict with O.H. & S. compliance. The second consideration is that of a

compliance effectiveness analysis. In other words, will effective compliance be met such that reasonable precautions or due di I igence defence will be available in the con text of downsizing and re-structuring? With this approach, the answer is less clear. On the one hand, the caselaw interpreting the meaning of "corporate due diligence" does not, again, specifically require the presence of a full-time O.H. & S. compliance man ager. On the other hand, due diligence is much more easily established where there is a full-time O.H. & S. compliance man ager and line supervisors who have, as a significant part of their responsibility, to ensure the occupational health and safety of workers. Where workers are left on their own, even under current theories of worker

"empowerment", the Courts have been less willing to accept that the corporation and senior executives have taken "every reason able precaution for the health and safety of workers in the circumstances". Therefore, there is some risk to companies and senior executives, when they downsize and re structure, of O.H. & S. violations and li

Finland has gone through a transition from a rural base society to an urban base.

The projects are financed by TEKES, FIMET, research institutes and the partici pating companies. When TEKES was set up in 1983, it was given responsibility for twelve broad-based govemment-led programs covering a range of technology areas as diverse as biotechnology and information technology.

Finland has also developed a strong position in the design of components for HVAC systems for commer cial use.

D projects within industry. In 1992, nearly two-thirds of TEKES's budget was spent on supporting industrial research development projects. The goal of the projects is to develop new equipment and systems for: • air pollution control of both outside and inside air

• achieving the optimum inside air condi tions for workers by taking into account health and working capacity and economic consideration

• process ventilation.

• Minor areas like heat recovery, manage ment of the systems, corrosion, spaces with high air quality, etc. During the 5 year period about 70 projects will be carried out. The total budget of the projects will exceed $20 million Ca nadian.

Finnish companies in the field of indus trial ventilation participate in both the plan ning and implementation of the program. Evaluation of the INVENT Program TEKES requires mid-course evaluation of all their technical programs by an out side consultant in the field. For the INVENT

program, a list of more than 100 names of candidates on a worldwide basis was de

The new increased emphasis on improved market place environment and energy conservation suggested on opportunity to develop inno vative products and services in the indus trial ventilation field.

The projects are based on a bottoms-up approach. Once the needs are identified by an end-user, a team is formed including re searchers, industry, and end users. The projects are coordinated by FIMET which is the Federation of Finnish Metal, Engi neering, and Electrotechnical industries. 92

base projects are: •Coordination. Carried out by FIMET(Fed eration of Finnish Metal-Engineering and Electrotechnical industries). • Target level. The aim is to evaluate opti mum air quality and thermal conditions (air velocity, temperature and air humidity) on industrial premises. • Design criteria. The aim is to evaluate the design criteria and to further develop them to serve the company projects.

This was cosponsored by University of Toronto, GHAG,and AWMA. The evaluation included a recommenda

This led to the INVENT Seminar in Toronto on Septem ber 20, 1994 where 12 Finnish speakers outlined the latest technology in industrial ventilation. Based on this meeting, busi ness opportunities and networks are being developed which will result in the import ing of this Clean Air Technology from Fin land to North America. The objective of the program is to help Canadian companies become more competitive and to build up two-way trade between Finland and Canada.

Investors and the law

Liabilities on contaminated sites

Arecently released decision of the

Ontario Environmental Appeal Board(EAB)has provided some important guidance in the deter

"As none of the other persons subject to this order has any financial capacity to com ply, this means that the entire clean-up cost falls on their shoulders. The Director's de

cision to attach personal liability to these individuals is based primarily on three fac-

investors paying for a clean-up and the Min istry of Environment and Energy doing so, then participation in management requires the investors to pay, regardless of degree or kind of involvement and even in the absence of fault".

In deciding the case, the EAB consid ered the responsibility of not only the prin cipal investors, but also the responsibility of the business' institutional lenders, the

two businessmen, Messrs. Bell and Harris,

The second factor is what might be called the "negligent investment" theory of liability: that any investor who fails to determine the

potential negative environmental impacts of a business before investing in it and who fails to ensure as a condition of investing that the company has an adequate environ mental protection system in place and funds to carry it out must suffer the consequences of this failure. The third factor is that once

was all that the EAB felt the government could expect from these individuals. However, the EAB also indicated that it was of the view that each case must be de

... IN THE SEARCH FOR THE ULTIMATE IN MOISTURE PROTECTION FOR OUR ARB V AND PROREAD ENCODER REGISTERS.

So, to provide the best reliability for our encoders, we decided to make oil-filled registers our standard. And, to guarantee your investment in our products, the New ARB V and ProRead still carry the same guarantee of compatibility with any system we manufacture today or may develop in the future.
