We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.
Problems/Comments
Water samples collected from standing water in the reserve pit exceeded Alaska Water Quality Standards for aluminum and barium. Based on a URS carbon dioxide soil gas survey of the gravel pad in 2001, approximately 20 percent of the resulting samples indicated the pad had elevated hydrocarbon concentrations. Light hydrocarbon sheen was observed when sediment was disturbed along the submerged northeastern margin of the pad and all around the inner reserve pit. Sheen tests produced light hydrocarbon sheen when sediment was disturbed in water bodies bordering the western half of the north margin of the pad. Spill date based on unspecified month and day in 1991, Woodward-Clyde Consultants reserve pit closure sampling. Date may be revised when more accurate information arises. Western Operating Area of the Prudhoe Bay Unit. Kuparuk River is 0.2 miles away.

|---|---|---|---|
| 6/8/2006 | Site Added to Database | Barium and hydrobarbons. | Bill Petrik |
| 6/8/2006 | Site Ranked Using the AHRM | Initial ranking. | Bill Petrik |
| 6/8/2006 | GIS Position Updated | Used TopoZone Pro in conjunction with Figure 1 and Appendix A, Historical Aerial Photos, of the Oasis Environmental "2006 Work Plan, Kuparuk 30-11-13 Phase II Site Assessment, Prudhoe Bay Unit" dated 4/11/06 and BP Exploration (Alaska) Inc. maps "Aerial Photo Mosaic, Colville to Canning River, July 1998, Prepared by AeroMap U.S., Anchorage AK" and "Kogru to Canning, October 2000". Used a 1:24,000 Scale USGS Topo Base Map, Large Map Size, at 1:24,000 Scale. Moderate confidence in the accuracy of the coordinates. Suggest taking GPS reading to improve accuracy. | Bill Petrik |
| 6/9/2006 | Update or Other Action | File number issued 300.38.246. | Aggie Blandford |
| 6/13/2006 | Site Characterization Workplan Approved | Sheen noted during previous investigation near NW corner of pad. Soil-gas study showed approximately 1/5 of pad may be contaminated with petroelum hydrocarbons, primarily near former wells. Workplan states that 31 boreholes will be drilled to characterize hydrocarbon contamination and estimate the amount of clean, restricted use, and contaminated gravel. Samples will be analyzed for DRO/RRO, with 20% of samples slao analyzed for GRO/BTEX. | Bill O'Connell |
| 11/28/2006 | Update or Other Action | Received Phase II site Assessment and Corrective Action Plan from Oasis on behalf of BPXA. Phase II found DRO concentrations highest in reserve pit, which will be excavated and taken to G&I. Gravel pad samples found DRO up to 1,740 mg/kg. Clean gravel will be excavated and used to backfill the reserve pit, excess clean gravel will be transported offsite for re-use. Commingled conditional use and restricted use gravel will be stockpiled onsite and sampled prior to transport to East Dock for landfarming or for reuse as appropriate. | Bill O'Connell |
| 1/22/2007 | Update or Other Action | Completed QA/QC of Phase II data. Data was found to be acceptable. | Bill O'Connell |
| 3/21/2007 | Exposure Tracking Model Ranking | Initial ranking. | Bill O'Connell |
| 10/23/2007 | Update or Other Action | CSM, HH CSM Scoping form, and Eco screening completed for this site by Oasis. | Linda Nuechterlein |
| 10/30/2007 | Site Characterization Report Approved | Received Kup. St 30-11-13 Corrective Action Report. The gravel pad and acces road were removed. Clean and conditional use gravel was used as on site backfill, or hauled off site for beneficial reuse at other pads. Restricted use and contaminated gravel were hauled to East Dock for landfarming. Confirmation samples were collected following removal of the gravel pad, DRO was detected ranging from 11 mg/kg to 426 mg/kg. PAH analyses detected naphthalene, fluorene, and phenanthrene at concentrations several orders of magnitude below ADEC cleanup levels. | Bill O'Connell |
| 2/28/2008 | Site Closure Approved | The Alaska Department of Environmental Conservation, Contaminated Sites Program (ADEC) reviewed the environmental records associated with exploration site Kuparuk State 30-11-13. This site had been contaminated by the release of a hazardous substance; however, based on the information provided to date, ADEC has determined that no further action is required, and that Kuparuk State 30-11-13 can be closed. The hazardous substance contamination has been adequately addressed and does not pose a risk to human health or the environment. | Bill O'Connell |
