| Remediation Details: |
|
| Reason for Report: SPILL |
| Cause of Condition: SPILL OR RELEASE |
| Potential Receptors: Nearest Well: Domestic - 440' WSW; Surface Water: Brantner Ditch - 530' W; Occupied Building: 640' N |
| |
| FURTHER SITE INV: | Up to twelve (12) soil borings will be advanced to 6 feet bgs to vertically and horizontally delineate impacts within and adjacent to the former excavation extent to evaluate COC concentrations in native soil. Confirmation sampling will be completed by the end of the fourth quarter 2022. The proposed soil boring locations are illustrated on Figure 2. |
| |
| HOW REMEDIATE: | A remediation strategy will be selected following the evaluation of soil analytical results. |
| |
| INITIAL ACTION: | On May 28, 2022, a release was discovered at the Brant HZ Pad (Figure 1). A water treater gasket failure resulted in the release of approximately forty (40) BBLS of production fluid were released from the water treater outside of containment. Following the discovery, mitigation activities were immediately initiated and approximately twenty (20) BBLS of spilled production fluid were recovered via hydro-vacuum and returned to on-site production tanks. In addition, approximately 30 cubic yards (CY) of impacted material were transported to the Waste Management Erie location and disposed of under PDC waste manifests. |
| |
| MONITORING PLAN: | Groundwater was not encountered during mitigation activities conducted between June 2 and 8, 2022, at the Brant HZ Pad. |
| |
| RECLAMATION PLAN: | The Brant HZ Pad is an active facility and there are no current plans for decommissioning or reclamation activities. This stated, following excavation activities, the location was backfilled, compacted and re-contoured for the tank battery operations to continue. |
| |
| SOURCE REMOVED: | Between June 2 and 8, 2022, approximately 30 cubic yards of impacted material were excavated adjacent to the water treater and transported to the Waste Management Erie Facility for disposal under PDC waste manifests. |
