Client: Virgin Islands Waste Management Landfill Authority Maguire has held the Solid Waste Services contract with the U.S. Virgin Islands Government since 1999. The current contract began in 2006 and has focused on environmental compliance improvements at the Bovoni Landfill, a 35‐acre facility that adjoins the Mangrove Lagoon in St. Thomas. Due to a long history of non‐compliance, which includes subsurface fires, leachate discharges to Mangrove Lagoon, and improper lead acid battery/vehicle disposal practices, USEPA issued a consent order during 2000. Presently, the Bovoni Landfill does not have groundwater monitoring or GCCS systems. As such, Maguire has prepared plans/specs for installation of these systems and has been in correspondence with the USEPA to finalize design of the groundwater monitoring and GCCS pursuant to 40 CFR 258 and 60 Subpart WWW. The proposed groundwater monitoring system is comprised of 11 monitoring locations, and the proposed GCCS consists of ~10,000 lf of collection piping, 50 gas collection wells, a 1,500‐cfm blower, a flare station, and a condensate storage tank. As part of future design services scheduled, Maguire will prepare plans/specs that include final build‐ out and cover design, slope stabilization, stormwater management improvements, and leachate management. Due to bedrock strike and dip configuration that accentuates hydraulic flow toward the Mangrove Lagoon, landfill leachate has been discharging from the area below the unlined landfill into the wetlands that adjoin the lagoon for the last 10 years. Additionally, leachate breakout has been exacerbated by uncontrolled stormwater flow. Maguire is also preparing/coordinating the permitting efforts associated with these compliance improvements. Permitting portions of this project will be extensive and will include the filing of a Coastal Zone Management (CZM) Major Land Permit, an environmental assessment report, and a Territory Pollution Discharge Elimination System (TPDES) permit.

Client: Virgin Islands Waste Management Authority The Anguilla Landfill is located approximately 2,000 feet east of the Alexander Hamilton Airport, on the south central portion of St. Croix. Available information indicates that the 35‐acre landfill has been in operation since ~1967 and contains waste deposited at depths up to 70 feet. The FAA owns the property and has long demanded the landfill be shut down because of the danger that birds attracted to the landfill posed to planes at nearby Rohlsen Airport. Due to a long history of violations and non‐compliance, the U.S. Environmental Protection Agency (USEPA) issued its consent order during 2001. Violations included: the creation of a large used‐tire pile in a part of the landfill that is inaccessible to emergency vehicles; the lack of inspections of incoming waste to make sure hazardous wastes are not being disposed of; the lack of groundwater monitoring under/around the landfill; the inadequacy of the fencing around the facility; and the presence of surface fires and long‐burning underground fires. In response to this, Maguire implemented an Access Restriction Plan and a Fire Suppression Plan during December 2002. Maguire has completed a draft 40 CFR 258 Compliance Work Plan and Schedule for submittal to USEPA Region 2. Examples of the evaluations that will be included as part of the draft compliance plan include the following: floodplains, wetlands, hazardous waste receipt, cover material requirements, vector control, explosive gas control, air criteria, access requirements, run‐on/run‐off control systems, surface water requirements, liquid restrictions, record keeping, closure design criteria, and groundwater. Maguire is currently under contract to complete the Final Compliance Plan. The Virgin Islands Waste Management Authority has requested that Maguire perform Landfill Volume and Non‐Methane Organic Compound (NMOC) Gas Emission calculations to comply with the USEPA New Source Performance Standards (NSPS) for Gas Emissions from a Municipal Solid Waste Landfill (40 CFR 60 Subpart Cc).

Client: Government of the British Virgin Islands Maguire Group completed a comprehensive Environmental Impact Assessment (EIA) for the Balsam Ghut Landfill on Tortola. Under contract to the government of the British Virgin Islands, Maguire prepared the EIA for a proposed landfill that would supplement existing waste disposal capacity that includes a municipal solid waste incinerator plant on the Island of Tortola. Maguire also completed the Pre‐Design Report for the proposed Balsam Ghut Landfill that included conceptual layouts, costs and details of several wastestream scenarios for a long‐term (20 years) disposal facility. Maguire used an EIA process that was modeled after the framework of the U.S. National Environmental Policy Act (NEPA). The EIA was conducted to complement the BVI’s National Integrated Development Plan (NIDP) by taking into account socio‐economic, environmental, physical and spatial parameters. Environmental sustainability was identified in the NIDP as a primary consideration. The steep slopes and heavy vegetation of the proposed site—typical of most Caribbean islands— posed several design, construction, and environmental protection challenges. Maguire’s EIA identified a number of environmental features, such as the Balsam Ghut watershed and the location of sensitive human receptors and marine resources. The Maguire Team documented the short‐ and long‐term potential consequences of developing the proposed landfill. Importantly, the EIA also documented mitigation measures that should be implemented to reduce or eliminate any negative impacts during construction, operation and ultimate closure of the proposed landfill.

Client: Town of Berlin, CT The 9.2‐acre Berlin Town Center site is owned by the Town of Berlin and was utilized by the Berlin Department of Public Works for the storage of road salt, sand and construction materials. The site is a former clay pit that was created by the Town’s historical brick‐making industries and was then utilized by the town as a disposal site for municipal solid waste (MSW). Previous investigations indicated that environmental contamination was present in the soil, sediment, groundwater and surface water. In addition, there was a 1‐to‐2‐foot‐thick layer of incinerated municipal solid waste present at the northern extent of the site at a depth of about 2 feet below the soil surface. Maguire conducted a Phase I Environmental Site Assessment (ESA) in accordance with Connecticut Department. of Environmental Protection (CTDEP) guidelines and to ASTM standards. The Phase I ESA Report included a summary of the data and identified potential areas of environmental concern at the Site which were investigated as part of the Phase III Environmental Site Investigation (ESI). Maguire prepared a Phase III Work Plan utilizing the Conceptual Site Model (CSM) process. The Phase III ESI consisted of the collection of soil, sediment and groundwater samples. Maguire prepared a Phase III ESI Report summarizing the results of the investigation, including an evaluation of remedial alternatives to achieve compliance with the RSRs based on the proposed use of the Site as a park and walking trails. A Remedial Action Plan (RAP) was developed for the site to achieve closure of the Site and capping of the MSW in accordance with the Solid Waste Regulations. Prior to initiation of remedial activities, Maguire prepared and obtained the “Authorization for the Disruption/Closure and Post‐Closure Use of a Historic Solid Waste Disposal Area”, CTDEP Flood Management Certification, Town Inland Wetlands Permit and the CTDEP General Permit for Contaminated Soil/Sediment Management for the Project. Maguire prepared Contract Documents for the Solid Waste Closure and evaluation of contractor bids. Maguire also provided on‐site environmental oversight services and environmental management during the remediation and closure activities at the Town Center Site. The project was completed in September 2007 and Maguire will be preparing the Solid Waste Closure Documentation for the Town.

Client: City of Woburn, MA Maguire’s services for this project include engineering and design services related to the environmental monitoring and permitting, and preparation of the final closure design of the 50‐acre municipal solid waste landfill. Maguire Group has prepared and completed the Initial Site Assessment (ISA), Comprehensive Site Assessment (CSA), associated groundwater sampling and analysis, the Final Closure Design Plan, and construction documents in accordance with the requirements of the Commonwealth of Massachusetts, Solid Waste Management Regulations. Maguire prepared a comprehensive final closure design plan which: reclaimed adjacent wetland areas; consolidated the waste footprint to minimize the total cap area and reduce closure costs; and coordinates the final grades with the relocation of the existing utilities to promote drainage, improve access, and increase the potential for post‐closure use. In addition, Maguire was instrumental in assisting the City to develop a program which will potentially offset a portion of the closure costs by accepting and controlling the use of non‐hazardous fill materials from the surrounding market to reshape the existing facility in preparation for the final closure. There were two closure design challenges for this project. The first of two design challenges for this project included the removal of extensive amounts of buried waste and the construction of a capping system within the right‐of‐way of two power transmission lines which trisected the landfill. The second design challenge was to incorporate a solution to a legal action brought on by an abutter to alleviate flooding caused by the landfill.

Client: Rhode Island Waste Management Corp. Johnston, RI The Central Landfill in Johnston, Rhode Island is the largest active landfill in New England. Owned and operated by the Rhode Island Solid Waste Management Corporation on over 600 acres, it accepts 3,000 tons of municipal solid waste each day. The R.I. Solid Waste Management Corporation selected Maguire Group Inc. to provide on‐call engineering, design and environmental services for the operation and expansion of the landfill. Projects included design and construction of two 12 acre landfill phases, each with double composite liners, dual leachate collection systems, and an interface liner between the existing, unlined portion of the landfill and the new phases. Maguire also prepared an analysis for landfill expansion alternatives, which resulted in a proposed 40 acre expansion to the 154 acre licensed landfill. Extensive hydrogeologic studies were conducted to characterize the groundwater and the effects of leachate from the existing landfill. Preparation of licensing documents and design for this expansion is currently underway, and involves relocating and restoration of a brook presently bisecting the proposed expansion area. Other projects include evaluation of reservoir sediments caused by landfill erosion and design of a dredging program to remove those sediments in accordance with the state regulatory requirements.

Landfill Permitting Design and Construction Johnston, Rhode Island
Client: City of North Haven, Connecticut The North Haven Landfill operated for over 30 years, providing municipal solid waste disposal for the City. Maguire Group has been working with the City of North Haven for the past 10 years performing all phases of landfill permitting, design, operations planning, construction, and closure of this 15‐acre municipal landfill. The engineering and design of the expansion and closure of the landfill were successfully performed by overcoming challenges incurred as a result of its location. The landfill straddles the 36‐inch sewer outfall for the City’s Sewage Treatment Plant, and is in the Coastal Zone. As a result, two landforms were ultimately developed to minimize the load on the outfall pipe, and a Hydrogeologic Assessment was performed to assess the impact of leachate on the adjacent Quinnipiac River. Maguire’s innovative landfill closure design included the use of bottom and fly ash residue from the local utility as a soil amendment in the landfill capping system. Maguire also performed resident inspection and construction administration services for this project. Closure of the landforms was performed in sequence with the southern portion closed in 1992, and the northern portion closed in 1994. Maguire also developed a conceptual Recreational Plan for use of the site following closure to meet the requirements of the Office of Long Island Sound Programs (OLISP).

Client: Town of Rehoboth, MA Rehoboth entered into a Consent Order with MADEP for closure of its 13‐acre unlined sanitary landfill. Maguire performed all engineering and hydrogeological services necessary to meet the requirements of the Consent Order, including site assessments, closure alternatives analysis, closure plan design, construction drawings and specs, construction administration, and resident inspection. Maguire also performed the permitting efforts required for construction under NPDES for stormwater, and under the Wetlands Protection Act for wetlands. Because the transfer station adjacent to the landfill would be active following closure, the project included a quantitative risk assessment. The closure plan included an evaluation of landfill reclamation as an alternative to capping in place. The Town chose the capping alternative based on economics; however, several abutters became concerned with the possibility of contamination of their drinking‐well water if the landfill was not completely removed. This prompted an extensive monitoring effort of water supply wells for several homes within 1,000 feet of the landfill. The monitoring results indicated the landfill was not impacting the residential water supply wells, and limited monitoring of these homes continued. The landfill capping design incorporated a flexible membrane liner as the barrier layer, and a composite geosynthetic drainage net to direct drainage off this shallow sloped landfill. Maguire designed an alternative cover over approximately one acre of the cap to allow the adjacent transfer station to remain in service after closure. A paved surface was constructed to allow traffic to be routed over the closed landfill to access the transfer station.

Landfill Gas Collection System Chicopee Sanitary Landfill South Hadley, MA
Client: Phillips Energy, Waitsfield, VT The Bondi’s Island Landfill is a 68 acre facility with an active gas collection systems. The gas is transported to the Springfield Resource Recovery (SRRI) facility where it is used as boiler fuel to produce approximately 20,000 lbs/hr of steam. In 1995 Phillips Energy, the owner of the landfill gas rights, contracted with Maguire Group Inc. to permit, design and provide construction inspection and administration services for a new LFG transmission line to also supply gas to the Springfield Wastewater Treatment Plant for use as fuel for their regenerative thermal oxidizer (RTO). The SRRI facility will continue to be the primary user of the gas with the excess directed to the RTO. The RTO was constructed in 1994 to destroy odorous emissions from the sludge compost reactor vessels and exhaust from the various sludge processing systems. Natural gas is used as fuel to combust the gases. Once the temperature in the RTO reaches 1500 degrees, landfill gas is introduced into the RTO along with the source air. This will enrich the Btu content of the source air and can become t he sole source of fuel for the ongoing operation. This arrangement will conserve up to 40 million CF/YR of natural gas. Maguire designed safety controls into the system to limit the flow of LFG into the RTO bases on combustion chamber temperature, and cause shut off of the LFG gas when the temperature within the RTO exceeds the recommended operating temperature of 1900 degrees, or it the RTO shuts down. Maguire also designed a flow control station to limit LFG flow to the RTO in the event that line pressure to the SRRI facility drops below a 2 psig minimum pressure setpoint necessary for the operation of the boiler. The project also includes a new insertion type mass flow meter and provisions to install a glycol filter to remove hydrogen sulfide from the gas. The new 2,300 foot underground transmission line is constructed of 8” high‐density polyethylene and is designed to carry 500 SCFM of gas at 2 to 3 psig. Two sumps with level indication serve to collect the condensate in the transmission line for subsequent manual discharge into the nearby aeration tanks.

Client: Prince George’s County Prince George’s County, Maryland Prince George’s County, Maryland, considered to one of the most progressive county governments in the nation, conceived plans to develop, own and operate a landfill methane gas recovery facility. The County selected Maguire Group Inc. to provide full engineering, and architectural services associated with the feasibility assessment, project design and construction administration for this facility. What resulted is the largest publicly‐owned landfill methane gas recovery and treatment project of its kind in the country. At the County’s Brown Station Road Landfill, 29 extraction wells consisting of perforated pipe collect 1.4 million SCF/D of methane gas. The gas is compressed, cooled, filtered, dried and transported via a two‐mile underground pipeline to the Prince George’s County Detention Center. There the gas is burned as primary fuel to provide heat, domestic hot water and electricity for the Center. Electricity is produced by combustion of the gas in the three Waukesha twelve cylinder, turbo‐charged spark ignition, reciprocating engines and three 850‐kilowatt generators. A total of 25.3 million KWHR/YR is generated and surplus electricity is sold to the local utility company. Revenues from the sale of this excess energy, along with the savings realized by not having to purchase fuel for heat and electricity has resulted in a revenue to the County for over $1 million annually. Future expansion plans include installing 23 additional wells and three additional engine generators. This has the potential to increase the gas production to 2.9 million SCF/D, bringing the total power generation capacity to 37 million KWHR/YR. The Prince George’s County Project provides an environmentally sounds and economically attractive solution to the utilization of landfill methane gas as an alternative energy resource.

Client: Combustion Engineering ABB, Windsor, CT Maguire’s services for this project included engineering and design services related to environmental permitting, site development and balance‐of‐plant for the municipal solid waste receiving and processing portion of the facility. Maguire Group Inc. completed the design and construction administration of two major projects on behalf of Combustion Engineering at the Mid‐Connecticut Resource Recovery Facility. The initial project was for the design of a 2,200 TPD facility utilizing refuse‐derived fuel (RDF) technology. The process systems include heavy duty metal pan feed conveyors, primary and secondary shredders, rotary electro‐magnetic separators, primary and secondary trummels, pneumatic conveyance and separation system and refuse derived fuel hydraulic conveyance system. The architectural design challenges of the project were two‐fold: to enclose the various processing operations and equipment within the building and to create human scale in an otherwise very large building. By carefully organizing the various elements of the building and utilizing different colors and textured metal panels, an interesting "human scale facade was achieved. Maguire provided full service architectural/engineering design and construction contract administration services on the project. In 1990, Maguire Group Inc. was retained by ASEA Brown Boveri, the parent of Combustion Engineering, to design an addition to the facility. The addition was constructed in phases to allow operations to continue in the existing facility. Maguire’s services included architectural, structural foundation, mechanical, HVAC, fire protection, plumbing and electrical design services, permitting and site design for the receiving and processing portions of the facility.

Client: R. H. White Construction Group and University of New Hampshire The University of New Hampshire (UNH), in cooperation with Waste Management of New Hampshire, has launched “EcoLine,” a landfill gas project that will pipe enriched and purified gas from Waste Management’s Rochester landfill to the Durham campus. UNH is the first university in the nation to undertake a project of this magnitude, and it is doing it with the help of Maguire Group, which has been providing planning and design services to connect the school’s new combined heat‐and‐power plant (COGEN) with the landfill. Methane is a by‐product of decomposing garbage and can also be a powerful energy source. In an innovative plan, UNH will use the landfill’s excess methane gas as the primary fuel for its new COGEN plant, once the 12.7‐mile pipeline is completed. Maguire Group, as a subcontractor to R.H. White Construction for this design‐build project, has been assisting with the permitting and easement application process that is involved to run the pipeline under land along the Spaulding Turnpike, Pan Am/B&M Railroad right‐of‐way, and University property within several towns. To avoid wetland impacts and other environmental concerns, the pipeline is being installed by directional drilling beneath valuable wetland resources and the Cocheco River. Once online, it is projected that the COGEN plant will provide 80‐85 percent of total energy requirements for the campus for 25 years. UNH’s reduced dependence on fossil fuels would make the campus one of the greenest in the nation. Construction began in August 2007, and UNH is expected to fuel its COGEN plant with landfill gas by the fall of 2008. When combined with the COGEN plant, this innovative landfill gas project will lower energy costs, provide energy security, and reduce the UNH Durham campus's greenhouse gas emissions an estimated 67% below 2005 levels and 57% below 1990 levels.

Waste‐To‐Energy On‐Call Technical Services U.S. Virgin Islands Client: Virgin Islands Waste Management Authority
Maguire Group and their subconsultant Gershman, Brickner & Bratton, Inc. (GBB) were selected by the United States Virgin Islands Waste Management Authority (VIWMA) to assist the Authority in negotiating Solid Waste Management Service Contracts (Service Contracts) with a waste‐to‐energy developer. The United States Virgin Islands Water and Power Authority (WAPA) issued a Request for Proposals (RFP) in December of 2007. The RFP solicited proposals from developers to propose alternative energy projects to reduce the Territories dependence on fuel oil to generate electricity and to reduce costs to ratepayers. In October of 2008, WAPA selected a proposal from Alpine Energy Group to construct waste‐to‐energy facilities on St. Thomas and St. Croix. WAPA invited VIWMA to collaborate on the project, with WAPA negotiating a Power Purchase Agreement (PPA) with Alpine and VIWMA negotiating municipal solid waste (MSW) Service Contracts with Alpine. The Alpine proposal included a facility on St. Thomas to handle waste from St. Thomas and the waste from St. John and Water Island that is currently disposed on St. Thomas, and a facility on St. Croix to handle that islands waste. Each island generates approximately 300 tons per day of municipal solid waste. The proposed facilities will use Refuse Derived Fuel (RDF) technology to convert the MSW into fuel for the power generating plants which are projected to produce approximately 16 MWs of electricity on St. Croix and 33 MWs on St. Thomas. Maguire evaluated the projects and provided due diligence review of the waste‐to‐energy proposal and assisted in negotiations for the Service Contracts for St. Thomas and St. Croix. As part of this task, we attended meetings and conference calls with the developer, and provided technical review, due diligence, and comment of the Waste Management Services Contract, and the Power Purchase Agreement, assisted in preparing all relevant technical appendices, and reviewed all associated equipment, facility, site, and operations parameters. On August 10, 2009, WAPA signed a 20‐year Power Purchase Agreement and VIWMA signed 20‐year Solid Waste Management Contracts with Alpine Energy Group.
