ESE was retained by a capital investment firm and developer to conduct a Phase II Environmental Site Assessment (ESA) on a maritime buoy manufacturing facility located in northwest Houston. The Phase II ESA confirmed the presence of chlorinated volatile organic compounds (VOCs) in shallow soils and groundwater at concentrations greater than Texas Commission on Environmental Quality (TCEQ) Protective Concentration Levels (PCLs). The release was the result of a leaking underground solvent storage tank. As a result of the Phase II ESA findings and on on behalf of the client, ESE enrolled the site into the TCEQ’s Voluntary Cleanup Program (VCP) and proceeded with site characterization activities in accordance with 30 Texas Administrative Code (TAC) §350 Texas Risk Reduction Program (TRRP). Upon completion of soil and groundwater plume delineation and characterization, ESE completed a Municipal Setting Designation (MSD) application, which was accepted by the City of Houston. The MSD effectively eliminated the groundwater ingestion pathway by means of institutional control. This allowed the Site to receive a Certificate of Completion from the TCEQ, upon approval of the Affected Property Assessment and Response Action Plan Plan.
