CERCLA Remediation and Construction Management—Boodle Mill Facility
GEMG personnel prepared remedial design and remedial action documents for the Boodle Mill mine tailings site for the client that was part of the Clear Creek/Central City Superfund Site. The remediation documents were approved by the United State Environmental Protection Agency and construction began in the fall of 1999.
The remediation consisted of excavating impacted soils and disposal at an onsite disposal cell. Remediation activities also consist of drainage improvements to reduce the surface water run-on at the site. A French drain system will also be installed to capture groundwater from the disposal cell area. The disposal cell will be seeded with vegetation for stability. Also located on the site is a wetlands are that will be enhanced. Construction was completed in summer 2000. The final report was submitted to and approved by the EPA in August 2000.
Fuel Blending Facility Audit
GEMG personnel conducted an environmental records review of files at various sites as part of a financial transaction with a lending institution. GEMG personnel reviewed environmental records, existing environmental assessments, and interviewed staff from the environmental department. The purpose of GEMG
personnel’s review was to evaluate whether any major liabilities were present at the facilities that could affect the company financially.
Industrial Manufacturing Facility Audits
GEMG personnel conducted Environmental Compliance Audits at various sites as part of an overall compliance review by corporate staff. The audits were used to evaluate compliance of each plant, identify areas of deficiencies for correction, and assess overall environmental status. GEMG personnel conducted site interviews with employees; reviewed the manufacturing process; reviewed records on site; and reviewed local, state and federal records for compliance with applicable regulations.
UST Remediation—Folding Carton Facility
GEMG personnel provides technical consulting to this folding carton plant. GEMG personnel were assigned the project of evaluating the potential contamination resulting from inactive underground storage tanks containing RCRA-regulated materials. Other inactive tanks at the site had been used for the storage of heating oil.
GEMG personnel performed a series of initial studies including workplan development, interfacing with the State of Iowa, Department of Natural Resources, and prepared a site characterization report. Site characterization activities have included multi-media sampling including soils, ground water, stream sediments, and surface water.
GEMG personnel evaluated human health exposures in a baseline risk assessment for the chemicals occurring in the local soils and ground water. GEMG personnel designed the remediation program under a combination of the state underground storage tank regulations and federal RCRA regulations. GEMG personnel provided oversight of the tank removal contractor and confirmation sampling of both soils and ground water. Materials have been profiled for either recycling or disposal under applicable regulations.
Ongoing groundwater monitoring has occurred on a semi-annual basis since 1995. Constituent levels in ground water are now below the state water quality standards. Closure status was received in October 1999 by the IDNR. The monitoring wells were abandoned in December 1999.
LUST Site Investigation, Corrective Action Plan-Former Gasoline Station
GEMG personnel prepared the Site Summary Form (SSF) for the client at a motel site that was formerly a gasoline station. Leaking Underground Storage Tanks (LUSTs) had been present on the site and removed prior to the current property ownership. Contamination was left on site as well as piping associated with the gasoline station.
