Site Investigations and Closure

Site InvestigationPhase I and II ESA, Multiple Additional Investigations, Regulatory Support
Confidential Client, Texas
What began as a Phase I ESA on a seven-acre site developed into a lengthy series of investigations resulting ultimately in a No Further Action (NFA) letter from the Texas Commission on Environmental Quality (TCEQ). The Phase I ESA identified historical management of 70 acres including the site and surrounding area as a pecan orchard for more than 30 years. A Phase II ESA to assess potential impacts from this and other nearby property uses identified 1,2-dibromo-3-chloropropane (DBCP) and 1,2-dibromoethane (EDB) in groundwater from a temporary monitoring well on the southwest corner of the site.
After it was determined that closure requirements under the TCEQ Voluntary Cleanup Program would require extensive additional investigation of all areas of the property, EAE succeeded in obtaining closure under a subsequent enforcement action through a minimal groundwater investigation involving installation of three temporary monitoring wells and one permanent monitoring well in the southwest corner of the site. TCEQ provided the NFA approving the EAE Affected Property Assessment Report without comment.
