| A release was discovered during construction and tank anchoring at the Wirkner-Vance 3C-36HZ production facility. Of the approximately 3 barrels of crude oil released into secondary containment, approximately 2.75 bbls were recovered using a vacuum truck and then transfered to a licensed injection facility for disposal. Although a liner was present on location, it was temporarily breached to allow for anchor installation. Groundwater was encountered beneath the liner in a temporary anchor pothole at approximately 6 feet below ground surface (bgs). A groundwater sample (GW01) was collected and submitted for laboratory analysis of benzene, toluene, ethylbenzene, and total xylenes (BTEX). Laboratory analytical results received on June 11, 2014 indicate benzene, toluene, and total xylenes concentrations are in exceedance of applicable COGCC Table 910-1 regulatory standards, causing this release to be reportable. A topographic site map is included as Figure 1. |
