BUSTR Tier 1 Evaluation and No Further Action Achieved in Record Time

An Ohio municipality received a Notice of Violation (NOV) from Ohio’s Bureau of Underground Storage Tank Regulation (BUSTR) requiring that assessment be completed for a site where two underground storage tanks (USTs) had been removed decades ago. Township trustees were aware of the lingering problem; however, they had no idea how to resolve the issue. Desiring to genuinely address the problem, a trustee contacted Cox-Colvin & Associates for assistance based upon a professional referral.

Cox-Colvin gathered the available information from the Township and then contacted BUSTR on behalf of the municipality. BUSTR provided perspective on the history of the site, the issues at hand and provided available records for the site. Although the two USTs were removed in 1992, sampling that had been conducted over the subsequent 20+ years was inconclusive in determining whether remediation or other action was still necessary at one of the UST locations. BUSTR required that a Tier 1 Source Investigation be performed to determine whether contaminants were present above action levels. After reviewing the history and explaining the agency’s requirements to the trustee, Cox-Colvin personnel developed a statement of work and proposed a project budget.

Cox-Colvin’s site investigation included the completion of soil borings and the installation of three monitor wells to collect groundwater samples from within and near the former tank pit. Samples were submitted for analysis, and results demonstrated that contamination levels were below action levels. As a result, no remediation was necessary and our client was saved additional frustration and expense. Within days of Cox-Colvin submitting a Tier 1 Evaluation Report, our client received a No Further Action letter from BUSTR and the project was closed out. Cox-Colvin personnel returned to the site to permanently abandon the groundwater monitor wells and restore the site. The project, including a regulatory review and No Further Action (NFA) determination, was completed in less than 90 days and under budget, much to the delight of the Township trustees.
