Arc Environmental completed a hazardous materials survey of the Site, which identified petroleum products, ASTs, PCB containing equipment, bulk storage of regulated raw materials, flammable materials, corrosive materials, radioactive materials, and other wastes defined by the RCRA universal waste rule (fluorescent light ballasts, fluorescent light tubes, mercury and sodium vapor lamps, etc.). In addition, Arc Environmental completed an asbestos survey of the building and quantification of asbestos containing materials performed by EPA licensed asbestos inspectors. Our team worked with regulators to classify several of the identified asbestos containing materials, including galbestos coated metal sheeting and roofing materials, as non-friable, allowing them to be removed and disposed as non-regulated materials, saving the Client asbestos removal and disposal costs.
Arc Environmental completed the collection, characterization, consolidation, labeling and disposal of drums, containers, and sacks of hazardous and regulated materials and wastes. Waste streams included flammable liquids, corrosive liquids and solids, chlorinated compounds, oils and greases, aerosols, etc. Additionally, Arc Environmental removed and disposed of fluids from five transformer units with PCB concentrations ranging from 650,000 mg/kg to 990,000 mg/kg, and removed and disposed of fuel oil, waste oil, petroleum-impacted water, and sludge from eight ASTs.
Arc Environmental provided Response Action Plan implementation oversight during placement of the first phase of the required Site cap. Oversight included H&S monitoring during soil movement activities and documenting proper installation of the marker fabric and clean fill cap thickness. We completed clean fill certification sampling for clean fill to be used for cap construction at the Site. This task entailed preparation of a Sampling & Analysis Plan and negotiation of the final number and locations of samples with Maryland regulators, collection of the samples from an active off-Site construction site, and prepration of a final report documenting that sample results met the MDE residential cleanup standards for soil.
