Problems/Comments
Preliminary investigation conducted in 2001 indicated potential hydrocarbon contamination in portions of the gravel pad.

| 4/9/2008 | Site Characterization Workplan Approved | Received Phase II work plan for Getty State 1. 30 boreholes are planned for the gravel pad. Following field screening, selected samples will be analyzed for DRO/RRO with 25% of samples also analyzed for GRO/BTEX. An additional 5 boreholes are planned for the surrounding tundra. Additional characterization will be performed in summer 2008 in accordance with a supplemental work plan on an as-needed basis. | Bill O'Connell |
| 10/30/2009 | Document, Report, or Work plan Review - other | Reviewed Phase II Site Assessment Report and Corrective Action Plan. 35 boreholes were advanced on the gravel pad, with soil samples collected from the surface to approximately 5 feet bgs, with some deeper samples also collected. DRO concentrations ranged from ND to 10,300 mg/kg in a sample from borehole GP30 from 4-4.5 feet bgs. GRO was also detected up to 9,580 mg/kg in borehole GP17 at 3.5 to 4 feet bgs. Hydrocarbon impacts are also likely around borehole GP14, though no sample was collected. Five boreholes advanced and sampled in the surrounding tundra but did not indicate any impacts. It is estimated that approximately 1,900 cy of restricted use and 2,700 cy of contaminated gravel are present at the site. Please see the next action for CAP information. | Bill O'Connell |
| 10/30/2009 | Document, Report, or Work plan Review - other | Reviewed Phase II Site Assessment Report and Corrective Action Plan. Please see previous action for Phase II results. The CAP plan for this site calls for removal of the entire gravel pad, excavation and capping of the reserve pit, plugging and abandoning the well and regrading the excavated areas with overburden in preparation for site rehabilitation. Approximately 24,200 cy of clean gravel will be excavated, with some gravel used on site to backfill the reserve pit and the remainder, estimated at 18,000 cy, transported to an off site staging area for reuse. The approximately 1,900 cy of restricted use gravel will be stopckpiled on site, resampled, and if it meets the criteria for conditional use, will be used to backfill the reserve pit. Approximately 2,700 cy of contaminated gravel will be transported to the East Dock Landfarm for Treatment. Following removal of the gravel pad, confirmation samples will be collected from the surface where overlying gravel was contaminated and from sidewalls 2 feet high or greater. Composite samples will be collected from areas where hydrocarbon contaminated gravel was removed (6 areas) and discrete samples will be collected from areas where Phase II data indicated DRO concentrations greater than 2,000 mg/kg. Composite samples will be collected at a minmum frequency of one per 5,000 square feet, with composite sidewall samples collected at a frequency of one per every 100 linear fet of sidewall, if necessary. | Bill O'Connell |

| 1/19/2011 | Final Cleanup Report Reviewed | Reviewed Getty State #1 Corrective Action Report. The gravel pad was removed entirely. Approximately 23,365 cy of clean gravel were excavated and used as onsite backfill, transported to Santa Fe pad for reuse, or used as backfill at SE Eileen. Approximately 2,200 cy of gravel identified as restricted use during Phase II sampling was transported to Pad 3, stockpiled, and sampled. Following receipt of sample results, approximately 700 cy was transported to East Dock for treatment and 1,500 cy were used as reserve pit backfill at MPU D Pad. Approximately 2,175 cy of contaminated gravel were removed and hauled to East Dock for treatment. Confirmation samples collected from the bottom and sidewalls of the gravel pad excavation did not contain contaminants above cleanup levels. | Bill O'Connell |

| 2/8/2011 | Cleanup Complete Determination Issued | The Alaska Department of Environmental Conservation, Contaminated Sites Program (ADEC) has completed a review of the environmental records associated with BPX Getty State 1 located in Prudhoe Bay, Alaska. Based on the information provided to date, it has been determined that the contaminant concentrations remaining on site do not pose an unacceptable risk to human health or the environment and this site will be closed. | Bill O'Connell |
