| INITIAL ACTION: | A compromised valve resulted in approximately 10 bbls of fluid to spill to the pad surface. The spill was contained entirely on pad and a vac truck was immediately dispatched to begin cleanup activities. The impacted soil was removed and hauled for disposal. |
| |
| RECLAMATION PLAN: | The location will remain an active oil and gas facility. Reclamation will be in accordance with COGCC 1000 series rules. |
| |
| SOURCE REMOVED: | Source removal occurred and approximately 4 cubic yards of impacted soil has been removed and hauled for disposal. Confirmation soil samples were collected and submitted for the previously approved amended SAP of TPH (C6-C36), Organics, Barium, EC, SAR, and Boron. Analytical results indicated TPH, Barium, EC, and Boron to be in compliance with Table 915 RSL concentrations. Unfortunately, due to miscommunication between the lab and consultant, the samples were not run for PAH's and are out of hold time. The analytical results did indicate elevated levels of SAR in SEP-B03@6". Additional source removal will occur and confirmation soil samples will be collected and submitted for TPH (C6-C36), Organics, and SAR. The use of RSSL concentrations to show compliance with Table 915 was previously approved on Form 19 Doc #403822267. The closest water well (DWR Permit # 311804) had a reported static water level of 200' bgs. |
