MacGillis & Gibbs NPL Site Remedial Action, New Brighton MN. Located in a Minneapolis suburb, wood pole preserving and treatment operations began at the 26-acre facility in the 1920s and fell into disrepair in the mid-1980s. As a DBE subcontractor, MARLEY provided the Contractor with environmental engineering services during the remediation of soils and groundwater contaminated with pentachlorophenol (PCP), creosote, and copper arsenate. MARLEY also prepared the project’s Erosion & Sediment Control Plan, Groundwater and Surface Water Protection Plan, Ambient Air Protection Plan, Noise & Dust Control Plan, as well as the groundwater treatment system’s Operation and Maintenance Plan.
Li Tungsten NPL Site – Interim Remedial Action, Glen Cove NY. Once a smelting and refining operation (1940 to mid-1980s) for processing ore and scrap tungsten to produce tungsten carbide powder, tungsten wire, and welding rods, the owners abandoned the 26-acre parcel located on the Long Island Sound. Primary hazards identified during this fast-track cleanup included unmarked and severely corroded drums of hazardous chemicals, heavy metals, PCB waste, and low-level radiation from slag and ore residues containing thorium, uranium and radium. As a DBE subcontractor, MARLEY prepared and implemented the Site Safety and Health Plan needed to safely identify, screen, sample, segregate and stockpile 8,000 CY of radioactive debris, slag, and ore residue. Field responsibilities included storm water inspections, as well as performing, maintaining and calibrating air and radiation monitoring equipment, daily health and safety meetings, site-specific and hazard communication training, fit testing, maintaining field health and safety files, enforcing personnel and equipment decontamination activities, and issuing hot work permits.
CERCLA Property Remediation and Restoration Project, Salem Acres NPL Site, Salem MA. This project involved the excavation, material handling, blending/mixing, transportation and off-site disposal of an estimated 37,000 CY of high-BTU grit and scum waste (sludge) contaminated with metals, polynuclear aromatic hydrocarbons, dioxins/furans, PCBs, and volatile organics. As a subcontractor, MARLEY’s remedial planning responsibilities included the preparation and implementation of a Stormwater Erosion and Sediment Control Plan, Health and Safety Plan, Excavation & Material Handling Plan, and Chemical Data Acquisition Plan (CDAP) intended to follow the hazardous waste’s disposition from cradle-to-grave.
