Project Description
The project site is a commercial cardlock facility. BB&A Environmental was retained to decommission abandoned underground storage tanks (USTs) and undertake required cleanup, assessment, and reporting requirements. Following UST decommissioning activities, and based upon the results of soil and groundwater sampling, BB&A Environmental recommended undertaking a risk-based assessment of the site as the most cost effective approach leading to regulatory site closure. To this end, BB&A Environmental undertook the following investigative actions:
- Delineation of the vertical and lateral extent of soil impact through the installation of soil probes to allow collection of soil and groundwater samples
- Determination of remaining concentrations of contaminants of concern (COC) through constituent based, or compound specific, laboratory analysis
- Development of a conceptual site model (CSM) and determination of potential exposure pathways and potential receptors at the site
- Evaluation of the degree of impact from COC through a comparison of compound specific results with the risk-based concentration (RBCs) listed Risk-Based Decision-Making for Remediation of Petroleum Contaminated Sites
- Reporting all findings of the investigation in a corrective action plan (CAP) to be submitted to the Oregon Department of Environmental Quality (DEQ) for approval and issuance of a “no further action” (NFA) or site closure letter
Having completed these investigative and reporting tasks, BB&A Environmental successfully obtained on behalf of the client regulatory site closure and issuance of an NFA determination from the DEQ.
