Last Update: 11/21/2017 In 2013-2014, excavation of petroleum-contaminated soil was completed at five of the six pad areas identified for action in the Cleanup Plan (Pump House, Vehicle Maintenance Shop [VMS], Incinerator Building, Western Landfill, and Northeast Landfill). A total of 8,900 cubic yards of petroleum-contaminated gravel was excavated and staged on the pad for landfarming the following season. Excavations were guided by existing data, soil odors, visual observations, and the results of qualitative screening of the soil with a photoionization detector (PID). At most locations, the gravel was removed down to the native soil (peat and silt), which was five to six feet below the original pad surface. Confirmation sampling was conducted for benzene, toluene, ethylbenzene, and xylenes (BTEX), polynuclear aromatic hydrocarbons (PAH) and GRO, DRO, and RRO. The concentrations were either non-detectable or well below ADEC Method Two cleanup levels at all locations. Petroleum hydrocarbon concentrations were also below the site specific-cleanup levels established for the gravel pad, with a few minor exceedances at the Pump House, VMS, and Incinerator Building. The remaining contamination (located five to six feet below the original pad surface) is limited in extent, relatively low in concentration and does not pose a risk to surface water. Furthermore, at least some of the DRO and RRO detected in the floor samples has been attributed to natural organics (peat) in the sample matrix. Almost all of the excavated areas, including the sample points with exceedances, were backfilled with clean fill.

6/24/2005	Site Characterization Workplan Approved	Staff reviewed the site characterization workplan submitted by Husky Energy on behalf of the PRPs. Samples will be collected from the landfill soil, and adjacent surface water bodies during the July sampling event. Samples will be collected for DRO/GRO/RRO, BTEX, PAHs, VOCs, PCBs, and metals. If persistant organic pollutants or metals are found to be a problem, a second round of sampling will occur during mid-August to evaluate migration of contaminants to the lagoon sediments. A magnetic survey will be conducted to delineate the extent of the landfill. Sorbent pads will be used to abate the existing oil seeps during the first fieldwork effort and will be checked on the second trip.	Emily Youcha
7/15/2005	Interim Removal Action Approved	During site characterization efforts, two drums containing product were intercepted during test pit trenching. One spill, of 0.2 gallons of product impacted surface water and PERP was notified.

Approximately 1 quart of product was immediately cleaned up.	Emily Youcha
7/29/2005	GIS Position Updated	GIS Position provided by Husky Energy.	Emily Youcha
11/7/2005	Update or Other Action	Contaminated Sites staff reviewed a preliminary data report for the Camp Lonely Landfill. The lateral extents of the landfill were defined with a geophysical survey and four distinct burial areas were found. It was estimated that approximately 17,000 cubic yards of material is present in the landfill, of which 70% is soil. On two occasions during characterization efforts, buried drums were intercepted causing petroleum product in the drums to spill. The drums and impacted contaminated soil and water were removed. Results of the site characterization indicate diesel-range organics (DRO) exceed Method One soil cleanup levels but do not exceed Method Two soil cleanup levels for the Arctic Zone. Residual range organics (RRO), total xylenes, chromium, and arsenic exceed Method Two soil cleanup levels. The elevated concentrations of RRO and chromium are associated with surface staining. Background sampling locations indicate background DRO concentrations in soil may be above Method One soil cleanup levels and background arsenic concentrations may be above Method Two soil cleanup levels. Benzene, mercury, total aromatic hydrocarbons, and total aqueous hydrocarbons were detected above water quality standards during one sampling event at a nearby isolated pond, but during a sampling event one month later, all concentrations were below water quality standards. Polychlorinated biphenyls were not detected.	Emily Youcha
11/14/2005	Meeting or Teleconference Held	Staff spoke with CIRI to request additional sampling data when CIRI was conducting the Camp Lonely demolition. A meeting is scheduled for 11/15 to discuss the results.	Emily Youcha
11/28/2005	Meeting or Teleconference Held	Staff held a meeting with Husky Energy and their consultant to discuss the Interim Characterization Report. Staff had some concerns about the chromium hot spot and requested analysis to determine the form of chromium. Staff inquired about surface water sample CLSW01 and suggested follow-up sampling. It was determined that the current risk to human health is low due to the current land use and the type of contamination (mostly low-level petroleum) and erosional impacts are lower due to the distance from the beach. The proposed cleanup levels were briefly discussed and it was agreed that Method Two soil cleanup levels would be too high because surface water may be impacted in the future due to erosional processes. A lower cleanup level was desired to limit DRO mobility in the pad and 2,000-3,000 mg/kg was proposed. It is estimated that about 80% of the contaminated soil is under 3,000 mg/kg and the rest above 3,000 mg/kg. The final report is due Jan. 31, 2006 and a followup meeting with the PRPs should be held in early February. Staff will submit initial comments on the interim report to Husky Energy.	Emily Youcha
11/29/2005	Update or Other Action	Staff recieved a copy of the Draft Camp Lonely Decommissioning Environmental Assessment Summary Report from CIRI dated Nov. 18, 2005. 7 Areas of concern were discovered: Bulk Fuel Storage Area with 1-65,000 and 1-120,000 gal AST and Pumphouse; 3,500 gallon portable fuel tank; Incinerator/Utility Building area (Incinerator Bldg, Generator Room, and associated ASTs); and Vehicle Maintenance Shop Area (Vehicle Maintenance Shop, communication Shop, Loading Dock area, and associated ASTs). Field screening was used and analytical samples for DRO/GRO/RRO and BTEX were collected. Concentrations exceeded Method One cleanup levels and at the 1300 gallon AST at the Vehicle Maintenance Shop, one sample exceeded Method Two cleanup levels for DRO.	Emily Youcha
12/8/2005	Meeting or Teleconference Held	Staff attended the Restoration Advisory Board meeting in Barrow and provided a summary of the current activites at the site. BLM Realty indicated that CIRI may be staging equipment on the pad this spring. DEC and BLM HazMat indicated the equipment should not be placed on the landfill or other areas of contamination due to upcoming remedial efforts.	Emily Youcha
2/15/2006	Meeting or Teleconference Held	Staff met with the PRPs on Feb 10 for an update meeting. Staff discussed the site characterization report which was recieved on Jan 31, 2006. Staff discussed the proposed cleanup levels for the DRO contamination found in the landfill. A representative from DEC Solid Waste Program was present to answer solid waste related questions and landfill permitting. Staff requested a feasibility study from the PRPs and it is anticipated the feasibility study will begin sometime this summer.	Emily Youcha
2/15/2006	Site Characterization Report Approved	Staff reviewed the site characterization report for Camp Lonely. Four burial areas were found based on the results of a geophysical survey. The landfill was thought to be constructed around 1975 and was later expanded at the southwest corner based on aerial photography. On average, the landfill material is estimated to be 70% soil and 30% debris. The estimated total volume of debris is 5800 cu. yds and 16000 cu. yd of soil (excluding the cap). Contaminants of concern include DRO, GRO, RRO, xylenes, arsenic, chromium, and ethylene glycol. Approximately 80 samples were collected from testpits, soil, water, and soil vapor in the northwest, west-central, and southwest burial areas. The northeast burial area was not characterized.	Emily Youcha
5/25/2006	Meeting or Teleconference Held	Contaminated Sites staff participated in a meeting with the Camp Lonely potentially responsible parties (PRPs). The proposed petroleum cleanup levels were discussed and DEC recommended Method One cleanup levels because the site is in an eroding environment. A new settlement agreement will be completed to include a feasibility study. The settlement agreement should be finalized within a month and the feasibility study will probably be completed by early fall. The other areas of concern on the Camp Lonely pad may be included into the feasibility study.	Emily Youcha
6/29/2006	Update or Other Action	Staff received an update from CIRI. The PRPs are working to reach an updated settlement agreement to include the feasibility study. A feasibility study will likely occur this summer. Additional sampling may also occur this summer to follow up on data gaps from the site characterization in 2005.	Emily Youcha
8/11/2006	Update or Other Action	Staff received a 2006 workplan to collect addtional data at the landfill. A few soil samples will be collected from the landfill to fill in data gaps. Additional samples will be collected from the adjacent surface water. A sheen test will be conducted, to get a better understanding of the concentrations of DRO that will produce a sheen in water. The work will occur in late August.	Emily Youcha
8/17/2006	Meeting or Teleconference Held	Contaminated Sites staff met with the potentially responsible parties (PRPs) for the Camp Lonely Landfill to discuss their updated settlement agreement. The PRPs would like to continue negotiation of the petroleum cleanup levels next month. Additionally, staff outlined the process required to reach a Record of Decision for the site. A feasibility study will be completed by December 2006, Proposed Plans in summer 2007 and a Record of Decision to follow. It is expected that a cleanup will occur in summer 2008.	Emily Youcha
10/12/2006	Update or Other Action	Staff received the preliminary data from the 2006 investigation. Benzene exceeded the water quality standards (TAH) in the adjacent surface water and pore water concentrations were 1000 ug/L or more.	Emily Youcha
10/12/2006	Meeting or Teleconference Held	Staff met with the PRPs to discuss cleanup levels for the site. Staff informed that that DEC would like MEthod One cleanup levels (200 ppm) due to the recent discovery of benzene in the surface water (exceeding TAH standards) and pore water (pore water concentrations up to 1000 ug/L and higher). There is likely a point source in the landfill contributing to the high concentrations. It may be possible to negotiate the cleanup level higher (500 ppm) in areas that are not along the edge of the pad or if point sources are removed.	Emily Youcha

Update or Other Action

Contaminated Sites staff reviewed a preliminary data report for the Camp Lonely Landfill. The lateral extents of the landfill were defined with a geophysical survey and four distinct burial areas were found. It was estimated that approximately 17,000 cubic yards of material is present in the landfill, of which 70% is soil. On two occasions during characterization efforts, buried drums were intercepted causing petroleum product in the drums to spill. The drums and impacted contaminated soil and water were removed. Results of the site characterization indicate diesel-range organics (DRO) exceed Method One soil cleanup levels but do not exceed Method Two soil cleanup levels for the Arctic Zone. Residual range organics (RRO), total xylenes, chromium, and arsenic exceed Method Two soil cleanup levels. The elevated concentrations of RRO and chromium are associated with surface staining. Background sampling locations indicate background DRO concentrations in soil may be above Method One soil cleanup levels and background arsenic concentrations may be above Method Two soil cleanup levels. Benzene, mercury, total aromatic hydrocarbons, and total aqueous hydrocarbons were detected above water quality standards during one sampling event at a nearby isolated pond, but during a sampling event one month later, all concentrations were below water quality standards. Polychlorinated biphenyls were not detected.

Meeting or Teleconference Held

Staff held a meeting with Husky Energy and their consultant to discuss the Interim Characterization Report. Staff had some concerns about the chromium hot spot and requested analysis to determine the form of chromium. Staff inquired about surface water sample CLSW01 and suggested follow-up sampling. It was determined that the current risk to human health is low due to the current land use and the type of contamination (mostly low-level petroleum) and erosional impacts are lower due to the distance from the beach. The proposed cleanup levels were briefly discussed and it was agreed that Method Two soil cleanup levels would be too high because surface water may be impacted in the future due to erosional processes. A lower cleanup level was desired to limit DRO mobility in the pad and 2,000-3,000 mg/kg was proposed. It is estimated that about 80% of the contaminated soil is under 3,000 mg/kg and the rest above 3,000 mg/kg. The final report is due Jan. 31, 2006 and a followup meeting with the PRPs should be held in early February. Staff will submit initial comments on the interim report to Husky Energy.

Meeting or Teleconference Held

Staff met with the PRPs on Feb 10 for an update meeting. Staff discussed the site characterization report which was recieved on Jan 31, 2006. Staff discussed the proposed cleanup levels for the DRO contamination found in the landfill. A representative from DEC Solid Waste Program was present to answer solid waste related questions and landfill permitting. Staff requested a feasibility study from the PRPs and it is anticipated the feasibility study will begin sometime this summer.

Site Characterization Report Approved

Staff reviewed the site characterization report for Camp Lonely. Four burial areas were found based on the results of a geophysical survey. The landfill was thought to be constructed around 1975 and was later expanded at the southwest corner based on aerial photography. On average, the landfill material is estimated to be 70% soil and 30% debris. The estimated total volume of debris is 5800 cu. yds and 16000 cu. yd of soil (excluding the cap). Contaminants of concern include DRO, GRO, RRO, xylenes, arsenic, chromium, and ethylene glycol. Approximately 80 samples were collected from testpits, soil, water, and soil vapor in the northwest, west-central, and southwest burial areas. The northeast burial area was not characterized.

5/25/2006

Meeting or Teleconference Held

Contaminated Sites staff participated in a meeting with the Camp Lonely potentially responsible parties (PRPs). The proposed petroleum cleanup levels were discussed and DEC recommended Method One cleanup levels because the site is in an eroding environment. A new settlement agreement will be completed to include a feasibility study. The settlement agreement should be finalized within a month and the feasibility study will probably be completed by early fall. The other areas of concern on the Camp Lonely pad may be included into the feasibility study.

Emily Youcha

6/29/2006

Update or Other Action

Staff received an update from CIRI. The PRPs are working to reach an updated settlement agreement to include the feasibility study. A feasibility study will likely occur this summer. Additional sampling may also occur this summer to follow up on data gaps from the site characterization in 2005.

Emily Youcha

8/11/2006

Update or Other Action

Staff received a 2006 workplan to collect addtional data at the landfill. A few soil samples will be collected from the landfill to fill in data gaps. Additional samples will be collected from the adjacent surface water. A sheen test will be conducted, to get a better understanding of the concentrations of DRO that will produce a sheen in water. The work will occur in late August.

A feasibility study will be completed by December 2006, Proposed Plans in summer 2007 and a Record of Decision to follow. It is expected that a cleanup will occur in summer 2008.

Emily Youcha

10/12/2006

Update or Other Action

Staff received the preliminary data from the 2006 investigation. Benzene exceeded the water quality standards (TAH) in the adjacent surface water and pore water concentrations were 1000 ug/L or more.

Emily Youcha

10/12/2006

Meeting or Teleconference Held

Staff met with the PRPs to discuss cleanup levels for the site. Staff informed that that DEC would like MEthod One cleanup levels (200 ppm) due to the recent discovery of benzene in the surface water (exceeding TAH standards) and pore water (pore water concentrations up to 1000 ug/L and higher). There is likely a point source in the landfill contributing to the high concentrations. It may be possible to negotiate the cleanup level higher (500 ppm) in areas that are not along the edge of the pad or if point sources are removed.
