MSD for South Dallas Property
W&M was contacted by the City to assist a community non-profit organization with the environmental closure of a solvent plume originating from an historic dry cleaner on the property. The Grand Plaza Shopping Center located on Grand Avenue in Dallas, Texas has been the subject of extensive investigations and testing, including Brownfields Assessment Grants and a vapor intrusion study under EPA’s Superfund Innovative Technology Evaluation (SITE) program.
The City offered technical guidance to assist ICDC with the preparation of an application for a Municipal Setting Designation (MSD) to remove the groundwater ingestion pathway associated with the groundwater plume. An MSD process involves providing technical and location information to the City of Dallas and the TCEQ to demonstrate that there is no potable use of groundwater in the Site vicinity, and therefore that cleanup of groundwater to drinking water standards or other ingestion pathways is not required. W&M completed the CIty of Dallas MSD application, public meeting/City council hearing, TCEQ application, and final closure documation for this Site.
