Beaver Valley Nuclear Power Station Demolition

First Energy Corporation
Shippingport, PA – 2005-2006 – $350,000

Scope of Work:
Homeland security regulations required removal of five multi-story office buildings surrounding this nuclear power station in order to open up defensive lines of sight. The buildings were contaminated with asbestos-containing materials and electrical equipment that contained PCBs.

Neumeyer Environmental removed over 2,500 cubic yards of asbestos materials and approximately 250 cubic yards of PCB-containing electrical components. Following removal of these contaminants, Neumeyer Environmental demolished the structures and recycled 1,900 tons of steel and non-ferrous metals. One structure housed a full-scale model breeder reactor, 14′ in diameter and 50′ high, constructed during the 1950s. We constructed a shipping container and relocated the model to a storage facility. The reactor model will be displayed in a museum dedicated to the history of nuclear power.

The renovation and upgrade of the nuclear power facility is an ongoing process due to the magnitude of the work. The project is being performed with a focus on recycling and salvage in support of environmental conservation.

PennDOT Findley Connector Project

DCK Worldwide, LLC (Dick Corp)
Clinton, PA – 2004-2005 – $1,400,000

Scope of Work:
New roadway construction required crossing an abandoned landfill that had operated for fifty years, unpermitted and unregulated, in a former strip mine pit. The landfill contained both municipal and industrial wastes. The industrial waste contained heavy metals and chemical solvents.

Neumeyer Environmental excavated 300,000 cubic yards of soil and segregated it by contaminant concentration. We recycled the uncontaminated soil as roadbase material to be used on-site. We placed the minimally contaminated soil in an on-site containment cell that PA Department of Environmental Protection (PADEP) permitted specifically for the project. Neumeyer Environmental profiled the remaining soil as either residual or hazardous waste and transported it to appropriate disposal facilities.

By segregating the soils, we were able to retain on-site and reuse 270,000 of the 300,000 cubic yards originally excavated, saving millions of dollars in transportation and disposal costs.

PennDOT Bayfront Connector Highway

DCK Worldwide, LLC (Dick Corp)
Erie, PA – 2003-2004 – $1,600,000

Scope of Work:
PENNDOT encountered soil contaminated with heavy metals and industrial herbicides in the process of constructing a four-lane road connecting Interstate 90 and Interstate 79 in Erie, Pennsylvania. The contaminated soil was located within the footprint of the proposed 6 acre storm water retention basin required for the project.

Neumeyer Environmental removed 22,000 tons of soil from the site. We installed a barrier of compacted limestone across the base of the excavation overlain with plastic sheeting. This barrier system allowed construction of the retention basin to continue in an uncontaminated environment.

Neumeyer Environmental provided 40-hour HAZWOPER training for the project personnel to allow specialty crews, such as utillity and carpentry crews, to continue with the highway construction.

PennDOT 12th Street to Broad

Brayman Construction Corporation
Erie, PA – 2002-2003 – $740,000

Scope of Work:
A new highway construction project required construction of a bridge over an active main line railroad and a scrap metal processing facility. The soil at the site contained elevated levels of benzene, pesticides, and lead that required special management.

Neumeyer Environmental excavated 50,000 tons of contaminated soil for off-site disposal. We collected 220,000 gallons of contaminated groundwater and treated it on-site to reduce the contamination to levels acceptable for discharge to a publicly-owned treatment works (POTW). Neumeyer Environmental installed a protective barrier to protect workers from exposure.

Neumeyer Environmental controlled worker exposures through a variety of engineering controls so that the crews could work with only limited personal protective clothing. Eliminating this requirement and treating the contaminated groundwater on-site saved the client substantial operating and disposal costs.

North Shore Connector – Miller Printing

Brayman Construction Corporation
Pittsburgh, PA – 2008-2009 – $200,000

Scope of Work:
Neumeyer Environmental was contracted to provide environmental management and construction support services for a subway connector tunnel beneath the Allegheny River from downtown Pittsburgh to the North Shore area. The terminal end of the tunnel included a station to be constructed on a parcel that previously housed a print factory in a previously industrialized area of the city. The site is located between the Rivers Casino and Heinz Field. Neumeyer Environmental’s scope of work included performing the construction surveys, sampling and analysis of potentially impacted subsoils, and management of contaminated materials.

The parcels within the zone of influence of vibration-inducing activities included Heinz Field and several other structures currently in use. Neumeyer Environmental performed the surveys and installed multiple monitors within the structures so the prime contractor could evaluate potential structure movements during select work activities. When the construction is complete in 2010, Neumeyer Environmental will perform the post-construction surveys to provide a record of the structural condition after the work.

Neumeyer Environmental performed sampling and analysis of the excavation materials to determine if the materials classified as clean fill or required special management. Several areas of the site exhibited contamination that required off-site management. This pre-classification of the materials allowed the prime contractor to better stage the materials during the work.
