W&M Finalizes MSD, VCP, Waste Management Unit Closure and Site Decommissioning

As part of the decommissioning of a 100+ acre former manufacturing facility, W&M completed an environmental assessment of this Site which included multiple Partial Response Action Areas (PRAAs).  This approach allowed for the identification of specific source areas which expedited the closure of large tracts of land at varying times as they reached completion. After data compilation and review of regulatory closure strategies, the use of a Municipal Setting Designation (MSD) was determined to provide the most cost-effective and efficient manner of risk-based remediation for the Site groundwater.  The property borders an active shipping lane, which required additional scrutiny by the City of Houston and additional investigation by W&M for completion of the MSD.  The Site received an MSD Ordinance from the City of Houston and is the largest land area MSD ever performed in the city of Houston.  It is the 8th largest land area MSD state-wide. Affected Property Assessment

VCP Closure in Lubbock using MSD process

The property contained a fabrication plant that had experienced a release of chlorinated solvents into soil that migrated into the underlying groundwater in the 1990s. The site was entered into the Texas Voluntary Cleanup Program (VCP) in 1999 and extensive groundwater investigations were undertaken. The groundwater plume was defined to be located entirely on the Site and its stability had been established by over a decade of groundwater monitoring. Although no impacts to area water wells were identified, the concentrations exceeded default cleanup criteria established by TCEQ for Class 1 groundwater. Since all other exposure pathways had been addressed, a restriction on groundwater use was sought using the MSD process. W&M coordinated with the City of Lubbock’s environmental staff, and attended a public meeting and City Council hearing to describe the MSD process and demonstrate that the approval of an MSD on the property would be fully protective of environmental

VCP Closure in Grapevine Using MSD Process

A private client of W&M received certification from the Texas Commission on Environmental Quality (TCEQ) for a Municipal Setting Designation (MSD) to restrict groundwater use at a retail property located in Grapevine, TX. W&M worked with a local real estate developer, John T. Evans and attorney, C. Bishop Law to cleanup and close a contaminated property in Grapevine, Texas. The Site was contaminated with volatile organic compounds (VOCs) including several chlorinated compounds in the groundwater and to a lesser extent soil. The Site was entered into the Texas Commission on Environmental Quality’s (TCEQ) Voluntary Cleanup Program (VCP) and the remedy for the chemicals of concern (COCs) above the Texas Risk Reduction Program (TRRP) Protective Concentration Levels (PCLs) was a Municipal Setting Designation (MSD) from the City of Grapevine. W&M worked with the City of Grapevine to obtain the MSD certification and then submitted the MSD to the TCEQ. Following approval of the
