| Remediation Details: |
|
| Reason for Report: OTHER |
| Cause of Condition: SITE/FACILITY CLOSURE |
| Potential Receptors: Occupied structures, non-domestic well. |
| |
| HOW REMEDIATE: | As needed, site specific soil and/or groundwater remediation plans will be developed and submitted to COGCC via supplemental Form 27. |
| |
| INITIAL ACTION: | This form has been prepared to support removal of production equipment associated with this location. In accordance with COGCC Rule 911 and Rule 915, initial representative soil samples will be collected beneath the produced water vessel. Initial laboratory soil analysis will include only BTEX, 1,2,4 and 1,3,5 Trimethylbenzene, naphthalene, TPH, pH, EC, SAR and boron. Groundwater, if present, will also be collected and analyzed. Identified impacts will be reported as required for each discovery, and a Form 19 will be submitted, and remedial investigation will be conducted with excavation equipment. |
| |
| RECLAMATION PLAN: | No reclamation will be performed on the site unless the entire facility is removed from service or the activities migrate outside the original facility footprint. If these occur, the disturbance will be reclaimed in accordance with 1000 Series Rules, in collaboration with the landowner, and reported in a Form 4 (Sundry Notice) with proper documentation to demonstrate compliance with requirements for final reclamation. |
| |
| SOURCE REMOVED: | If a suspected release is identified and confirmed through soil screening and/or laboratory analysis during decommissioning of this facility, soils may be removed and transported to a licensed disposal facility. Transport and disposal records will be kept on file under usual and customary practice and are available upon request. If all source material cannot be removed during excavation activities, additional methodologies will be proposed in subsequent Form 27 supplementals. |
