Historical Lead-acid Battery Casing Disposal Plan. Working with a private client, Continental Placer was retained to resolve historical lead-acid battery casing disposal on property owned by a government agency. Continental Placer prepared and received agency approval for a Removal Action Work Plan, excavated and treated the lead-hazardous material and disposed of treated material off-site in a local solid-waste landfill. The excavation was backfilled with clean material and seeded to the agency’s specification. The stream-lined project was completed within five weeks of receiving Work Plan approval.
Permitted, Designed, and Constructed a Soil-Vapor Extraction System. The Continental Placer Team permitted, designed, and constructed a soil-vapor extraction system at a municipal landfill for a major solid waste disposal company. Construction and operation of the SVE system was selected as corrective action measures to remediate VOC impacts within established groundwater monitoring zones. The source of VOC was suspected to be a result of methane gas migration from former unlined portions of the landfill.
Phase I Environmental Site Assessments: Continental Placer has performed hundreds of Phase I property transfer Environmental Site Assessments (ESAs) for a variety of industrial, legal, financial, and private clients throughout the US. Phase I Environmental Assessments have been performed using the ASTM 1527 and 1528 standards or protocol streamlined for a particular client need, and our reports incorporate the USEPA “all appropriate inquiry” standards to provide comprehensive due diligence for commercial property transactions. Compliance with the “all appropriate inquiry” regulations is a requirement for insulating buyers from potential liability under the federal Comprehensive Environmental Response, Compensation, and Liability Act (“CERCLA,” also known as “Superfund”).
Phase II Environmental Investigations: Usually as a result of identifying recognized environmental concerns (RECs) through the course of performing Phase I ESAs, a soil and/or groundwater assessment is needed to define potential liabilities. Phase II ESAs includ additional reviews to clarify regulatory status or citations; confirmatory investigations of piping or structures for which use or purpose was not understood; sampling of soil gas, soil, groundwater, and/or building materials quality; and performing non-intrusive studies (geophysics) to identify the presence of sub-surface features (i.e., petroleum storage tanks). Continental Placer summarizes the findings from the Phase II ESAs into concise, confidential reports and provides recommendations to the clients for future site activities and potential remedial mitigation.
