Problems/Comments

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.

11/15/2005 Meeting or Teleconference Held Staff held a meeting with CIRI to discuss the additional areas of concern on the Camp Lonely pad. Emily Youcha
11/28/2005 Site Ranked Using the AHRM 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

2/16/2006 Site Ranked Using the AHRM Initial site ranking. 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 Meeting or Teleconference Held Staff met w/ CIRI and Husky Energy to discuss the AOCs on the Camp Lonely pad. Staff agreed that additional sampling is not required this summer and that that soil can just be removed and/or treated during the 2008 Landfill removal. Confirmation samples will be needed after removal of the contaminated soil. Additional samples are recommended for volume estimates for treatment purposes, but CIRI thought they had a good estimate of volume. DEC recommended 2000 ppm cleanup levels if they have control of the pad and can maintain restrictions on the use of the gravel. Emily Youcha

4/13/2011 Report or Workplan Review - Other Contaminated sites staff reviewed and sent comments on the Camp Lonely draft Record of Decision for Camp Lonely Landfill and Associated Pad. Tamar Stephens
7/7/2011 Meeting or Teleconference Held Contaminated sites staff participated in a comment resolution meeting on July 7, for a decision document for the Camp Lonely Landfill and pad. Major concerns with the draft decision document were satisfactorily resolved. Major issues included a clearer understanding of: the scope of the proposed work; how previously undetected contaminants would be identified and managed during removal of the landfill; cleanup levels for confirmation sampling at the landfill and for treatment of petroleum-contaminated soil; cleanup of underlying native soil; and management of additional volumes of waste or contaminants if found. Representatives from the Bureau of Land Management Arctic Field Office were present, and options for obtaining a permit or right of entry to conduct the work were discussed. Tamar Stephens
6/18/2013 Meeting or Teleconference Held Participated in first teleconference of the field season. Planned work includes excavation of the Western and Northeast Landfills, excavation of petroleum contaminated soil at 6 areas within the gravel pad, shipping solid waste and hazardous substances not suitable for landfarming off-site, and landfarming petroleum contaminated soil on-site. DEC will receive weekly field work status reports and participate in teleconferences every other week. Melody Debenham
9/24/2013 Meeting or Teleconference Held Participated in last teleconference of the field season. Removal activities are complete at the Western Landfill and the Northeast Landfill, and excavation activities are complete at the petroleum contamination areas within the gravel pad. 599 tons of solid waste and contaminated soil was shipped off-site this field season, including 213 tons of solid waste, 47 tons of asbestos containing materials, and 339 tons of lead, chromium, and PCB contaminated soil. Scrap metal for recycling is baled and staged for off-site transport next year. Petroleum contaminated soil is stockpiled on-site for landfarming next year. Melody Debenham
