RETAIL PETROLEUM / TRUCKING Company SITE
Zanesville, Ohio
CPEG provided environmental consulting and engineering services to prepare a work plan for closure of two oil/water separators and a Class V injection well system closure at truck maintenance facility. The work plan was prepared in accordance with the American Petroleum Institute (API) Recommended Practice 1604, "Removal and Disposal of Used Underground Storage Tanks", CFR 280.70-74, Region 5 Guidelines on Conducting Site Assessments at Class IV and Class V Injection Well Facilities, and Class V Well Closure Requirements. CPEG negotiations with the Ohio EPA were successful in eliminating excavation and removal of underground piping which saved significant costs on the project.
The project included CPEG oversight and coordination during closure activities. Closure activities included removal of existing fluids and demolition of the two oil/water separators; scour jetting of the influent and effluent piping, Class V injection well distribution box and associated injection lines; and capping each of the lines at each of the ends. Distribution injection lines were excavated and removed. Impacted soils encountered during excavation activities were stockpiled, sampled and transported to an off-site facility for treatment. Soil samples were collected from beneath each oil/water separator and from beneath the excavated distribution lines to verify impacted soils had been removed. A rinsate sample was collected from the scour jetting wash water to verify the lines had been cleaned. Excavated soils which appeared non-impacted were stockpiled, sampled for verification, and then returned to the excavations as fill material.
A Class V and Injection Well Oil/water Separator Removal Report documenting the aforementioned activities was prepared and submitted to Region 5 of the Ohio EPA. As a result, a “No Further Action” status was received for the site. This status was considered a significant asset for the sale of the property.
Total cost of project: $12,670
