Problems/Comments
The site was used to operate a lighthouse and associated navigational aide support between 1903 and the 1970s. The original Scotch Cap light station was destroyed by a Tsunami wave in 1946 and rebuilt in 1950. The facilities include a radio tower, hoist-house, lighthouse, three two-story dwellings, a boathouse, barracks and a shed. Six USTs (one 1,000-gallon, one 3,000 gallon, and two 10,000 gallon, and two unknown) and four ASTs (two 3,000 gallon and two 10,000 gallon) remain; petroleum contaminated soil; landfills (architectural plans and drawings suggest that a landfill was maintained for the disposal of solid waste while the facility was operational); building debris. The U.S, Coast Guard and the Corps of Engineers have investigated the site in the past. Corps determined no-further-action is needed under the FUDS Program. USCG removed some batteries, transformers, drums of used oils, paints, ect. in 1997. The Corps of Engineers conducted a preliminary assessment in 1989. It documented two sumps on the east side of the old barracks which contained petroleum product and emitted strong odors; a landfill; a ravine north of the lighthouse which contained drums, debris and an oily sheen on the creek.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 6/15/1989 | Preliminary Assessment Approved | "Field Investigation Report Phase I Preliminary Assessment" by E&E, Inc. 12 soil, 2 POL and 9 building material samples taken. Stained ground observed but no analyses results in this report. | Former Staff |
| 12/1/1989 | Update or Other Action | (Old R:Base Action Code = SI - Site Investigation). Hazardous and Toxic Waste report Phase I PA by E and E Inc. Surface samples showed up to 14,000 ppm TPH and Several BNA compounds, lead and .5 ppm Aroclor 1254(below 10 ppm threshold action value). Subsurface soil showed up to 6000 ppm TPH and several VOC (including PCE) and BNA compounds. One sample contained 110 ppm lead. A sample from sewer manhole showed elevated metals which may be the result of waste oil discharge to the sewer. POL samples identified as gas and/or diesel fuel. Asbestos was found in building materials. | Former Staff |
| 1/1/1990 | Update or Other Action | (Old R:Base Action Code = RAPR - Remedial Action Plan Review (CS)). Pre-design report Phase I Preliminary Assessment by E&E, Inc. discussed alternatives and requirements for cleanup and disposal. | Former Staff |
| 5/7/1990 | Site Added to Database | Petroleum, asbestos, solvents and paints. | Former Staff |
| 1/22/1993 | Site Ranked Using the AHRM | DOD staff ranked site and score = 45. Site = Lighthouse, barracks area, landfill, ASTs. | Former Staff |
| 1/15/1998 | Update or Other Action | USCG Environmental Site Assessment Report completed. No formal ADEC approval. It states that transformers, drums, batteries etc were removed in 1997. No report provided on the removal. | John Halverson |
| 12/31/1998 | Update or Other Action | Woodward-Clyde completed three investigative reports characterizing environmental concerns at the LORAN Station Cape Sarichef and Light Station Scotch Cap. The reports indicate the presence of asbestos-containing materials and lead-based paint at both locations. The asbestos and LBP were found to be in poor condition throughout these two facilities. | Linda (Qi) Liu |
| 9/15/1999 | Site Ranked Using the AHRM | Site re-ranked using existing data from the Corps of Engineers and USCG. DRO is primary contaminant of concern found to date. | John Halverson |
| 8/16/2005 | Update or Other Action | PGDC submitted a Site Survey Investigation report on behalf of USCG. It covers USCG Cape Sarichef LORAN station, USAF Cape Sarichef White Alice site and Scotch Cap LORAN station. It summarized the spatial survey results at the three sites with the purpose of potential future improvements including new towers and buildings, as well as retrofit of existing building. The investigation also included an examination of existing facilities, soil inspection, and suitability for proposed construction evaluation. The recommendation was to either install three new pre-fabricated fiberglass shelters at each sites or install these infrastructures at only two LORAN stations. | Linda (Qi) Liu |
| 5/10/2006 | Update or Other Action | File number issued 2527.38.003 | Hannah Lager |
| 7/11/2006 | Update or Other Action | Staff provided comments on a draft removal/site characterization workplan for Scotch Cap and Cape Sarichef. The USCG effort will dovetail on the USACE FUDS work that will take place in August. | Anne Marie Palmieri |
| 7/12/2006 | Update or Other Action | All past site reports were received electronically and placed in the site file (2527.38.003) on the Juneau server. | Anne Marie Palmieri |
| 5/22/2007 | Exposure Tracking Model Ranking | ETM ranking | Anne Marie Palmieri |
| 9/24/2007 | Site Characterization Report Approved | Environmental Due Diligence Audit report (8-07) approved this date. DRO contamination found at 2 ASTs and 2 USTs. 4 ASTs and 4 USTs contain product or product + water which should be removed before it spills. A battery was noted on the surface of the landfill, but no contamination associated with the landfill samples. | Anne Marie Palmieri |
