Subject: Closure of the St. George Island, Alaska Operable Unit.

Dear Ms. Roberts:

In accordance with paragraph S9 of the PribilofIslands Environmental Restoration Agreement (Two-Party Agreement or TPA) signed in January 1996 by designated officials of the State of Alaska and the National Oceanic and Atmospheric Administration (NOAA), NOAA requests Alaska Department of Envirorunental Conservation (ADEC), as the duly authorized representative of the State of Alaska, celiification of NOAA's completion of corrective action for the St. George Island Operable Unit (OU).

NOAA and the ADEC identified a total ofthiliy-six (36) sites at St. George Island (Table 1). This number (36) exceeded the twenty-five (2S) source areas identified in the TPA (Attaclunent A, St. George Island) due to agreed upon changes in the manner of site designation and the finding of new sites during various phases of site investigation. NOAA notes that one site, TPA 11 Cottage C UST is not subject to the TPA, and will be evaluated under NOAA's envirorunental safety compliance program in coordination with ADEC. However, NOAA remediated contamination at Cottage C to the maximum extent practicable. NOAA also notes that Oceanfront Site 36 (Table I) free-phase product (refer to: 18 AAC 7S.990 (43» expressed itself as a light sheen on the water table following removal of the

overlying vadose zone. In the Corrective Action Report and Conditional Closure Request for St. George Island TPA Site II Former Diesel Tank Farm, and the Former Drum Storage Area, TPA Site 2, NOAA determined that it (NOAA) had met its obligation to recover the free-phase product to the maximum extent practicable (refer to: 18 AAC 75.325 (f) (l )). Consequently, NOAA in its closure request for TPA I and 2 requested that the contaminated groundwater at the site be considered not to have recoverable free phase product. Subsequently, on November 2,2007, ADEC approved NOAA's request and granted a no further action planned (NFRAP) determination for TPA Sites I and 2, which included a determination on the contaminated groundwater that NOAA designated as its Site 36. Also, in a letter dated August 8, 2005. ADEC approved NOAA's Drafi Long-term Groundwater Monitoring Plan, St. George Island, Alaska, (Plan). NOAA issued its Plan on August 19,2005. The Plan included NOAA's long-term commitment to monitor groundwater at the aforementioned sites in addition to other sites on the island.

NOAA asserts that it has completed in accordance with the TPA all investigations and corrective actions approved by ADEC to the maximum extent practicable by:

• removing drums and debris • removing underground storage tanks (USTs) and above ground storage tanks

(ASTs) • removing fuel pipelines • removing contaminated soil • closing solid waste sites, • characterizing surface water, and • characterizing and monitoring groundwater.

Table I summarizes specific environmental quality parameters at each site. Parameters in Table 1 include type of contamination (drums, surface debris and solid wastes), media contaminated (soil, surface water, and groundwater), presence or absence of residual contamination with succinct comments regards land use (aka institutional) controls, as appropriate, the date ADEC signed the NFRAP determination per TPA paragraph 59, and the current property owner.

Appendix I includes copies of all deed notices recorded with the Alaska Recorder's Office, Aleutian District, for twenty-seven (27) properties affected by residual contamination, and/or buried debris remaining in-situ at three (3) sites listed in Table I. In addition, notice of residual contamination and/or buried debris will be identified in quitclaim deeds NOAA is drafting as it continues to transfer real property to St. George Island entities in accordance with the Transfer of Propel1y Agreement signed by NOAA and various PribilofIslands' entities in 1984.

Appendix II includes photocopies of the following three document types. (I) NFRAPs including signatures of both the ADEC and NOAA project managers (TPA paragraphs 42-47) for each site listed in Table 1; the photocopies are sorted in the same order as the site listing in Table I, excepting NOAA Sites II (Cottage C) and 36, which

do not have NFRAPs as discussed above. TPA paragraph 59 states: "A DEC shall not deny certification that corrective action is complete at any site(s) solely on the basis that post-remedial measures, such as monitoring, shall remain in place for a period of months or years." The NFRAP photocopies generally exclude report appendices containing items such as quantitative laboratory data and daily logs that are available to ADEC with NOAA's initial site submittals. (2) A St. George Village long-term groundwater monitoring plan. (3) A summary document describing in-situ residual soil and groundwater contamination.

In addition, pursuant to TPA paragraph 57, NOAA maintains an administrative record (AR) for the St. George Island OU at the following four locations: St. George Island Tribal Government Center; ARLlS, Anchorage, AK; NOAA Sand Point, Seattle, W A; and the National Archives and Records Administration, Seattle, W A. Currently, the AR is complete through fiscal year 2007. Fiscal year 2008 documents will be added to the AR by the end of November 2008 .

Per this submission, including Appendices I and II, NOAA requests ADEC concurrence that all corrective actions pursuant to the TPA between ADEC and NOAA signed in 1996 for the St. George Island Operable Unit are complete. Enclosed are two copies of a signature page attesting to the fact that no further remedial action is planned ("conditional closure status") for the St. George Island Operable Unit. I have signed both copies as NOAA's project manager pursuant to TPA paragraph 42.

If you concur, please sign both copies on behalf of ADEC, returning one signed copy to me and retaining the other copy for ADEC's records.

If you have any questions, please do not hesitate to contact me either in writing, or at (206) 526-4560.
