ENGINEERING RISK/DUE DILIGENCE
PROPERTY ASSESSMENTS
Coal Mine Feeds a 1,340 MW Electric Plant
Environmental and due diligence assessments of properties/facilities are designed to evaluate
environmental conditions and identify the legal tools available to manage, limit and allocate
environmental liability risks at a given property. EMC2
staff has completed environmental liability
assessments for manufacturing facilities, waste management facilities; active and abandoned mines,
mill and smelter sites, and petroleum retail/bulk terminal/refinery sites. Our personnel bring previous
operational experience in these industries, as well as an in-depth understanding of applicable
regulations and industry standards necessary to provide a realistic assessment of potential property
liabilities.
Coal Mine Facility – Our typical approach to an environmental assessment project is illustrated by a
recent due diligence assessment we completed for a potential purchaser of a 1,340 megawatt “mouth of
the mine” coal-fired generating facility in Western U.S. Working as part of a due diligence team that
included financial, legal, insurance and operations specialists; EMC2
evaluated existing and future
environmental liabilities associated
with the coal mine. This work
included assessing environmental
liabilities and estimating reclamation
costs and cash flow schedules under
various operating/closure scenarios,
as well as looking at innovative
contractual, technical and regulatory
strategies and insurance products
available to control or cap the
identified liabilities.
Aluminum Production Facility – Reviewed soil, groundwater, air and surface water sampling data;
hazardous material use/disposal records; permit and permit violation information; and release reports
and clean-up records at an operating aluminum production facility located in northwestern United
States. Assessment results were used to estimate environmental liabilities and related remediation costs
resulting from historic operations.
Automotive Parts Facilities – Reviewed records, interviewed employees, performed inspections
and sampled environmental media and waste streams to assess and quantify environmental liabilities at
four manufacturing facilities in Ontario, Canada.
Europe Petroleum Facilities – Reviewed records and sampled groundwater and soils at
representative petroleum retail, bulk terminal and refinery sites in Belgium and Luxembourg.
Investigation results were used to estimate environmental liabilities and remediation costs at the sites
selected for assessment. Remediation costs for non-assessed sites were predicted based on the
estimated costs for similar assessed sites. Texaco used these cost estimates in indemnification
settlement negotiations with the former owner of the facilities.
Former Mining Company Facilities – Assessed environmental liabilities and risks; determined
ownership and operational histories; and estimated closure requirements/costs for over 50 former
mining sites in the northwestern United States.
First Chemical Corp. of Mississippi Plant – Installed and sampled soil borings and groundwater
wells in order to delineate the extent of a benzene/nitrobenzene plume at this chemical manufacturing
facility in Pascagoula, Mississippi. After completing the site environmental assessment, EMC2
staff
prepared a RCRA Corrective Action Plan that included designs for lining the plant’s liquid waste pond,
excavating/disposing of VOC-impacted soils in the site’s landfill and installing a groundwater pump
and treat system.

REMEDIAL INVESTIGATIONS/FEASIBILITY STUDIES
RI/FSs are performed to characterize and evaluate remedial alternatives at sites where contaminant
releases have been identified. EMC2
personnel have been integral in completing RI/FSs at some of the
largest and most controversial sites on EPA’s National Priority List. As illustrated in the project
experience summaries provided below, EMC2
has helped our clients to identify, develop, and obtain
regulatory and public approval for cost-effective and protective solutions to site contaminant problems.
Milltown Reservoir/Clark Fork River Superfund Site, Montana - The Clark Fork River between
Butte and Missoula, MT has been impacted by nearly a century of historic mining, milling and smelting
activities in surrounding areas. Mine/mill wastes and tailings discharged into settling ponds and directly
into Clark Fork River tributaries (Silver Bow Creek, Gold Creek, etc.) during the late 1800s/early 1900s
were fluvially transported and deposited on the streambanks, channel bottom and floodplain along a 120-
mile reach of the river downstream to Milltown Reservoir. EMC2
staff has worked on investigation and
reclamation of these two operable units since 1992. This work currently involves completing Feasibility
Studies in anticipation of final remedy selection.
Hudson River PCB Superfund Site, New York -
EMC2
staff developed and performed the RI of PCB-
impacted soils and sediment at the Hudson River
Superfund Site in upstate New York. The work
included: preparing RI work plans; collecting over
1,300 soil samples for chemical analysis from shallow
and deep boreholes; coordinating sample analysis and
data validation; preparing technical memoranda and
reports detailing investigation activities/results and
defining the lateral/vertical extent of PCB impacts
for remediation.
Containment of PCB Impacted Sediments
Defense Depot Superfund Site, Utah - EMC2
staff completed the RI for the Defense Depot Site in
Ogden. The work included installing, testing and sampling monitoring/pumping wells and soil borings to
characterize the site aquifers and delineate a VOC plume. Subsequent to the RI, EMC2
staff oversaw
excavation and disposal of pesticide/herbicide impacted soils as part of defining and completing a
separate source removal action.
Anaconda Smelter Superfund Site, Montana - The
Anaconda Smelter Superfund Site is the largest Superfund
site by acreage in the United States. EMC2
staff was
involved in the remedial investigation, evaluation of
alternatives, remedial design and construction oversight
work on the various operable units at this site since 1991.
This work included completing an FS to evaluate
remedial alternatives for the approximately 20,000 acres
of impacted soil, tailings ponds, surface water and
groundwater included in the Regional Water, Waste and
Soils Operable Unit. Alternatives evaluated included
institutional controls, technical impracticability waivers
for groundwater quality standards, capping, cover soil
placement, source removal, storm water management and
stream habitat restoration.
Miami Mine, Arizona - EMC2
staff completed an engineering evaluation/cost analysis of cover options
for seven tailings impoundments covering 1,200 acres at this copper mine. The evaluation considered
numerous options for three basic types of covers: infiltration controlling, erosion controlling and oxygen-
consuming. Cover options were evaluated based on performance, cost, constructability, design life, future
land use, maintenance requirements and impacts from the tailings impoundments reclamation to ongoing
operations.

BROWNFIELDS/VOLUNTARY CLEAN-UP/LAND DEVELOPMENT
Brownfields are defined by the EPA as “abandoned, idled, or under-used industrial and commercial
facilities where expansion or redevelopment is complicated by real or perceived environmental
contamination.” Both government and economic drivers have created an intense interest in voluntary
clean-up and re-use of environmentally impacted land. EMC2
is well qualified to support Brownfields
projects and voluntary corrective actions from concept through completion.
National Zinc Site, Bartlesville, Oklahoma – After conducting the remedial design and overseeing the
remedial action at the site, 2-acres of metal-impacted soils remained on private property. EMC2
staff
was responsible for developing a cleanup plan that not only protected human health and the
environment, but also allowed for the redevelopment of the site into a soccer field for the Boys & Girls
Club of the City of Bartlesville. The design of the protective cap addressed the future reuse of the
property by including routing for future electric lighting, landscaping, parking lot and plans for future
institutional controls. The winning partnership between the State, the City of Bartlesville, the
Bartlesville Coalition, the PRP, and the private landowner was the key ingredient to the successful
redevelopment of the site.
Cannelton Industries – Former Tannery – EMC2
staff convinced USEPA and the Michigan
Department of Environmental Quality through the use of bioaccumulation studies and biological
monitoring to change their published $20 million Record of Decision remedy to a $5 million remedial
alternative. The site was remediated by installing a 2-mile protective rock wall along the St. Marys
River and removing 35,000 cubic yards of tannery wastes. Subsequent negotiations with the Planning
Department of the City of Sault Ste. Marie and the Eastern Upper Peninsula Planning and Development
Commission set the stage for a mixed-use redevelopment opportunity.
Cyprus Foote Mineral – Former Mineral Processing – EMC2
staff successfully negotiated and sold a
CERCLA Superfund site to a joint venture land development company in Pennsylvania, thereby
removing a $17 million liability from the client’s balance sheet. The agreement included negotiations
for an environmental insurance policy that provided two components: cleanup guarantee insurance and
remediation warranty insurance. The first covered the developer if cleanup costs exceed initial
calculations and the second provided up to 10 years of excess cost protection if further cleanup is
required. Both components also provided protection to the seller in the event that a bankruptcy would
return the liability to them. The USEPA National Brownfields Coordinator and the Region III Remedial
Project Manager supported the redevelopment of this site. Project approach involved the demolition
and hot spot removal combined with a groundwater pump and treat with long-term monitoring. The site
is to be developed into an office park.
Blackwell Zinc Site – Former Zinc Smelter - The City of Blackwell wanted a land-use plan developed
for the 188-acre former zinc smelter property that would be compatible with remediation and reuse of
the contaminated sites in the existing Blackwell Industrial Park. The Park is part of the Blackwell Pilot
Deferral Project, a site managed by the Oklahoma Department of Environmental Quality. EMC2
performed final design and construction management for the remediation of the property that ensured
that the remedy would remain protected during and after redevelopment.
Rico, Colorado – Former Mining Community – EMC2
staff is assisting the landowners, community
and the PRP to solve water quality and related issues. By working with the regulatory and community
stakeholders to develop a Brownfields-type remedial program that would best serve all stakeholders
high legal transaction costs and detailed investigations that are typical of CERCLA type actions will be
avoided. The plan will also be supplemented by applying to all applicable state and federal grant and
incentive programs.

economic analysis experience necessary to develop accurate estimates and to identify areas and degree
of uncertainty within these estimates. We follow a consistent approach that includes a rigorous quality
control checking process whether we are preparing budgetary estimates to help our clients select
between project alternatives or preparing detailed hard construction bid estimates for bonding or
project financing purposes.
Copper Mine Closure Cost Estimate, Michigan - EMC2
staff developed a detailed facility
closure cost estimate to provide reclamation cost and cash flow projections for surface reclamation of
an underground copper mine. Cost estimating work included: developing take-offs from construction
drawings of each facility to develop a focused building demolition cost estimate that included salvage
and scrap estimates, site reconnaissance to determine extent of environmental impacts, and regrading
and capping cost estimates for closure of approximately 5,000 acres of tailings ponds and several on-
site landfills.
Airport Expansion Fill Cost and Schedule Evaluation, Western U.S. - EMC2
developed cost
and schedule estimates for alternative methods of supplying and delivering approximately 23 million
cubic yards of fill material required for expansion of an international airport located in the western
United States. The work included evaluating the availability, suitability, cost, and permitting
requirements for various fill supply options including: development of on-site borrow pits;
development of new, or use of existing, marine-accessible borrow pits; use of existing overland truck-
accessible pits; or use of surplus material from other local construction projects. The evaluation also
included estimating the cost and schedule differences between various delivery options including
conveyor only, barge/conveyor, barge/trucking and trucking only.
Vat Leach Demolition Cost Estimate,
Arizona - EMC2
staff developed a demolition plan
identifying phased costs and schedules for a $1M
demolition of 10 concrete storage vats and
associated pipeline, conveyors and excavator
assembly used to leach high grade ore at this
copper mining facility. The vats were replaced by
a heap leach operation.
Leach Vats Demolition Cost Estimate
Coal Mine Closure Cost Estimate, Western U.S. - EMC2
developed detailed facility closure
cost and schedule estimates to provide cost and cash flow projections for reclamation of a large coal
mine in the western United States. The work included evaluating the technical/regulatory issues
associated with various pit reclamation options including recontouring to approximate original contour
and closure as shallow or deep lakes to minimize regrade quantities. Present value cost and cash flow
schedule estimates were developed for immediate closure and for continued mining/phased closure
scenarios. EMC2
’s scope also included evaluating various contracting options for completing the
reclamation work including using the mine’s existing equipment fleet and labor force, using an outside
reclamation contractor, or using a combination of both.
Miami Mine, Arizona - EMC2
staff completed an engineering evaluation/cost analysis of cover
options for seven tailings impoundments covering 1,200 acres at this copper mine. The evaluation
considered numerous options for three basic types of covers: infiltration controlling, erosion controlling
and oxygen-consuming. Cover options were evaluated based on performance, cost, constructability,
design life, future land use, maintenance requirements and impacts from the tailings impoundments
reclamation to ongoing operations.

RADIOACTIVE WASTE SITE CLOSURE
As demonstrated in the following representative project descriptions, EMC2
staff is experienced in
preparing and implementing mine and tailings reclamation plans and mill decommissioning plans for
Title II UMTRCA sites, as well as for radioactive contaminated sites located throughout the United
States. EMC2
’s staff has the knowledge and in-house capability to offer site investigations, remedial
design and construction, waste minimization, pollution prevention engineering and site closure
planning. EMC2
has experience in conducting environmental regulatory audits to assist clients in
meeting NRC and State regulations and offer program management for radioactive waste sites.
Split Rock Uranium Mill Site, Wyoming – EMC2
staff has managed the closure of this uranium
facility near Jeffrey City, Wyoming in a cost-effective and timely manner. Prepared a mill
decommissioning plan which entailed burial of the dismantled mill in the tailings impoundment.
Assisted with the development of a tailings reclamation plan involving three tailings impoundments
storing 8 million tons of tailings spread over 260 acres. Staff was instrumental in receiving NRC
approval of the reclamation plan and successfully implementing the construction over a 5-year (1994 –
1998) period. Long-term tailing stabilization was achieved by regrading and placing a multi-layered
cover system including a conventional clay radon barrier layer. The site received NRC acceptance of
surface reclamation work in 2001.
Sherwood Project, Washington - EMC2
staff has provided management services for all phases of the
regulatory process from developing a tailings impoundment closure plan to license termination for this
uranium mine and mill facility, located on the Spokane Tribe of Indians land near Wellpinit,
Washington. The site comprised of a mill, a lined tailings impoundment storing 2 million tons of
tailings spread over 100 acres and a solution holding pond. Staff was involved in the design of a
radiological soils cleanup plan, QA/QC program, internal technical audits and post reclamation
performance. The radon barrier cover system was very unique in that a thick, flexible loose sand cover
that promoted bio-intrusion was developed and approved by the Washington Department of Health.
This is the first unconventional cover of its type to be approved for an UMTRCA Title II site. A major
part of this project was on-going interaction with the various stakeholders, including WDOH, BIA,
BLM, Spokane Tribe of Indians, USNRC and the USDOE. In March 2001, the site successfully
terminated its license with the WDOH and became the first Title II uranium mill tailings site in an

cover/waste materials were transported/regraded to promote drainage. Fifty acres of geosynthetic clay
liner and a lateral sand drainage layer were placed over the four regraded remnant deposits to minimize
infiltration. Over 4,000 linear feet of geotextile and riprap were placed for erosion control along the
riverbanks of the remnant deposits. Over 2,000 linear feet of HDPE lined transfer channels were
constructed to route storm water around and across the capped areas to the river. Three separate borrow
areas were developed/reclaimed and over 200 acres were topsoiled and revegetated.
Pecos Mine, New Mexico – EMC2
staff designed and provided construction oversight for the
restoration of a tributary to the Pecos River, located in northern New Mexico, which was impacted by
metals and sediment loading from historic lead/zinc mining operations. Restoration included
temporarily diverting stream flow so that waste rock and metals-impacted soils could be removed from
the floodplain. This was followed by reconstruction 1,000 feet of the stream channel, banks, and
floodplain and revegetating the banks and floodplain with native species. Drop structures were installed
to approximate natural step/pool conditions. Buried grade control structures were installed to provide
long term channel stability, while maintaining a natural appearance.
