DEP Approves Cleanup Method Submitted by Chevron Environmental Management Company
FAYETTEVILLE, W.Va. – The Office of Environmental Remediation (OER) at the West Virginia Department of Environmental Protection (WVDEP) has approved a cleanup method submitted by Chevron USA on behalf of itself and its affiliates, including Chevron Environmental Management Company. The plan is to address environmental conditions through the DEP’s Voluntary Remediation Program at Chevron Facility #204779 in Fayette County.
The site is located at 131 South Court Street in Fayetteville and includes approximately 0.185 acres. The site was formerly used as an automotive service and gas station. Site improvements included an approximately 3,900 square feet shop with multiple repair bays, two 2,000 gallon gasoline underground storage tanks (UST) which have been removed, one 1,000-gallon gasoline UST which was closed in place, a removed dispenser island, and associated piping on an asphalt/concrete lot. The shop building remains on the site.
A series of environmental investigations beginning in 2001 indicated that soil and shallow groundwater at the site are impacted with petroleum hydrocarbon compounds. Quarterly monitoring and sampling (M&S) was initiated during the third quarter of 2002 and continued through the fourth quarter of 2005. Semiannual M&S was conducted in 2006 and 2008. In accordance with email correspondence from the WVDEP dated Aug. 27, 2008, groundwater samples were collected quarterly from monitoring well MW-4 and semiannually from monitoring well MW-6 from January 2009 through January 2010. The additional monitoring and sampling of monitoring well MW-4 was required to further establish decreasing trends of benzene concentrations compared with the varying seasonal water levels observed at the site. Additional monitoring and sampling of monitoring well MW-6 was to confirm historic non-detection trends and to ensure the plume was not migrating across Fayette Avenue.
A land use covenant has been negotiated to put the following institutional and engineering controls in place at the site: restriction on groundwater withdrawal for purposes other than monitoring or remediation and restriction of property to non-residential use only as that term is defined in 60CSR3. The land use covenant has been recorded with the property deed to ensure that the restriction remains in place in the event that the property is transferred to new ownership. Upon completion of the remediation, a final report will be submitted to OER for review and approval.
West Virginia’s Voluntary Remediation and Redevelopment Act encourages voluntary cleanups of contaminated sites, as well as redevelopment of abandoned and under-utilized properties, with an objective of counteracting the lack of development on sites with contamination or perceived contamination. The Voluntary Remediation Program identifies and addresses potential contamination at a given site; sets applicable remediation standards; and ensures that the standards are maintained at the site. By providing financial incentives to invest in brownfields, this approach protects communities and the environment while still promoting economic development in West Virginia.
