It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.

Problems/Comments

WAA No.3 is located on the southern side of the Lower Camp gravel pad. This source area is the former location of a paint and oil storage building. Waste oils and other liquids, as well as unused chemical products, have been stored at the site since the 1950s. The site was used as a WAA for drums beginning in 1977. The building, along with the rest of the Lower Camp structures, was demolished and removed in the mid-1980s. Based on the final Record of Decision (signed by ADEC on November 21, 2000), there is presently no unacceptable risk or threat to public health or the environment. The selected remedy is NFRAP. Institutional controls will be implemented for waste left in place and noted in state land records and within the Base Master Plan. Cap inspections and maintenance will be conducted and documented over a 5 year period (the first, third, and fifth years) to check that healthy vegetation exists and no erosion of the cover is occurring. After the last inspection, a 5-year review will be conducted to review the results of the inspections. If the cover material has remained in good condition, no further inspections will be required. Due to the close proximity and similar historical activities of IRP Sites SS07 and SS09, the maintenance and inspection program for IRP Site SS07 has been incorporated into the maintenance and inspection program for IRP Site SS09. ~13.5 Miles WSW of McGrath. Lower Camp Sites consist of: Hardfill No. 1 and WAA No. 1 (SS-011), POL Tank Farm (SS-003), WAA No. 3 (SS-007), Truck FIll Stand (SS-009), WAA No. 4, Old Sanitary Sewer System, Former Sewage Lagoon, and Former Paint Shop (SS-008), WAA No. 2 (Upper & Lower) and Upper Landfill No. 1 (LF-010), Lower Landfill No. 2 (LF-004), and the Airstrip (OT-006).

7/22/1988 Update or Other Action Final Technical Support Document for Record of Decision (dated February 29, 1988) received. Sites 1 (SS001), 2, 3, and 9 are spill/leak sites, sites 5, 7, 8, and 10 are previously used dumpsites or waste accumulation areas, site 6 is an area of Lower Camp road oiling, and sites 4 and 11 are the active landfill and waste accumulation area, respectively. Road Oiling {Site 6}-Road oiling at the Tatalina site occurred from the 1950's to the 1980"s. Waste oils were applied to the roads as a dust palliative and for disposal purposes. Until recently, the practice of road oiling to control dust was an accepted practice throughout the United States. Oils used in this manner do not release hazardous materlals into the environment because waste oils do not contain more than trace amounts of hazardous materials. Surface disposal of oil brings the oil into contact with organisms which readily biodegrade most petroleum hydrocarbons, leaving small amounts of weathered insoluble and immobile materials. There was no evidence of contamination found on or along the roads during the 1987 visit. No dark staining was apparent on or along the roadways. 2.3.6 Waste Accumulation Areas Nos. 3 (SS007) & 4 (SS008) - Lower Camp(Sites 7 and 8): These two waste accumulation areas are contiguous and located in the Lower Camp area. Sites 7 and 8 are areas in the old station complex used to accumulate drummed wastes from the power plant and motor pool, respectively. These areas were in operation from the 1950's to 1984 and were demolished and covered with one meter of fill material in 1987. Sites 7 and 8 were used to store drummed waste oils and motor pool wastes. Although minor leaks and spills have been reported in the past, no evidence of contamination existed during the 1987 site visit. No further action is therefore recommended for this site. Note attached to this document from ADEC project manager, Ray Burger, remarks that:USAF (David Paulsen Colonel March 7, 1988), USEPA (Jacques Gusmano February 21, 1988) and ADEC signed the ROD in 1988 (Bill Lamoreux July 22, 1988) , but the ROD was based on almost no sampling of some sites, therefore was deemed inadequate and a RI/FS was necessary.

4/19/1993 CERCLA SI EPA letter to Patrick M. Coullahan (LTC), Commander U.S. Air Force, 11th CEOS. This letter is to inform you that EPA Region 10 has completed the review of the Site Inspection (SI) report for the US Air Force Tatalina Long Range Radar Site, Alaska. The SI has been evaluated in accordance with 40 CFR Part 300 Appendix A, which is EPA's Hazard Ranking System (HRS) used to evaluate federal facilities for inclusion on the National Prioritles List (NPL). From our evaluation, EPA has determined that the site does not score high enough to be proposed for inclusion on the NPL. Therefore, a recommendation of no further remedial action planned (NFRAP) on the EPA'S part will be included in our Federal Agency Hazardous Waste Compliance Docket tracking system. If new or additional information becomes available that suggests the facility may score high enough to be proposed for the NPL, EPA must reevaluate your facility accordingly. EPA's NFRAP designation will NOT relieve your facility from complying with appropriate Alaska state regulations (i.e. A.S. 46.03, 18 AAC 75, 18 AAC 78, 18 AAC 60, 18 AAC 70, 18 AAC 80, 18 AAC 62). The Superfund Amendments and Reauthorization Act (SARA) of 1986, Section 120(a) (4)* requires federal facilities to comply with state cleanup requirements and standards when not listed on the NPL. All sources of contamination should be remediated to Alaska State clean-up standards. An alternative water supply should be provided IMMEDIATELY to on site personnel, and the water gallery well should be resampled. Analytical results should be provided to both the EPA and the state of Alaska. This facility will not be removed from the Federal Agency Hazardous Waste Compliance Docket, but as noted earlier, will be listed for no further action by EPA. If you have any questions regarding EPA's evaluatlon of the site, please contact me, at (206)553-1808. *NOTE To File: CHAPTER 103--COMPREHENSIVE ENVIRONMENTAL RESPONSE, COMPENSATION, AND LIABILITY SUBCHAPTER I--HAZARDOUS SUBSTANCES RELEASES, LIABILITY, COMPENSATION Sec. 9620.

3/31/1998 Update or Other Action The Department of Environmental Conservation (DEC), DoD Oversight group, received the Draft Remedial Investigation Report (dated February 1998) on February 10, 1997. The Draft Remedial Investigation Report includes a Baseline Risk Assessment, a Human Health Risk Assessment, and Ecological Risk Assessment. We appreciate the extended review deadline of March 31, 1998. We have completed our review of Draft Remedial Investigation Report and provided comments below. Please note, the Draft Risk Assessment sections are currently under review. A separate comment letter will be forwarded shortly. Provide rationale for the selected positions of BH9/MW and BH5 (SS-007 Oil/Paint Storage Building) in the same location. The building structure is recorded as 20-feet by 2-feet, this appears to be unrealistic dimensions. Please double check the building dimensions. Include the current septic system leachfield on the appropriate site figure. Gretchen Pikul
6/2/1998 Update or Other Action ADEC participated in a facility-wide site visit. Gretchen Pikul
10/13/1998 Site Characterization Report Approved Remedial Investigation Report (draft dated February 1998, final dated and received in October 1998) includes a risk assessment; ADEC comment letter dated March 31, 1998; comment resolution meeting on May 15, 1998. The objectives of the RI were to assess the impact of historic releases from the former building, confirm the absence or presence of groundwater in the area, and if present, define the nature of groundwater contamination and flow characteristics. The sampling locations used in the 1992 SI could not be determined; therefore, the information from that sampling was used as general guidance and not directly compared to data generated during the RI. The RI analytical data indicates that very low residual levels of organic contaminants were detected in soils beneath this site; however, the levels detected were all below human health and ecological risk-based levels presented in the baseline risk assessments, and no COCs or COECs were identified in the risk assessment for this location. In addltton, levels of contaminants were below current ADEC non-UST cleanup guidance and proposed cleanup standards in draft 18 AAC 75 regulations (November 12, 1997). No further action is recommended for SS-007, WAA No. 3. Gretchen Pikul

12/24/1998 Update or Other Action The Department of Environmental Conservation (DEC), DoD Oversight group, received the Draft Proposed Plan for No Further Action (dated December 1998) on December 8, 1998. The Draft Proposed Plan for No Further Action covers IRP Sites DP-005, OT-012, SS-001, SS-007, SS-009, LF-010, and OT-006, Tatalina LRRS, Alaska ADEC has completed our review and provided comments below. A State of Alaska Memorandum dated December 9, 1998 has also been submitted in response to this draft Proposed Plan; similar comments were noted but not reiterated in this comment letter. Within this Proposed Plan and the upcoming Record of Decision (ROD), a deed notice/land record (and dissemination of this information to current and future site workers), documentation of adequate cover, and an annual cover maintenances chedule (for 2-3 years following the final ROD) will be necessary at several sites. Theses ites include SS-009,LF-010, DP-005, and SS-007. In addition, site SS-001 will require a deed notice, as well as a mechanism to distribute this information to current and future site workers. The design and setup of the Recommended actions section stands out nicely and is easily read. While reviewing this Proposed Plan, several RI figures present "-" within the petroleum hydrocarbon analyses (GRO, DRO, and RRO). On the figures, the "-" indicates that the sample was not analyzed or reported for this parameter. However the laboratory data indicates that many of these sample data is "R" flagged; this information is not clearly discussed within the RI text. For example, SS-00 the MAR site, presents extremely limited data on the petroleum hydrocarbon compounds which was the potential contaminant of concern within this area. This flagged data and the rationale for no conclusive petroleum hydrocarbon data needs to be discussed during the comment resolution meetings on the Proposed Plan and the upcoming ROD. The site descriptions do not adequately capture the actual site description and site activities to sufficiently inform the intended readers (community members). For example, LF-004 is an active landfill, and WAA No. 3 had drum storage. Truck Fill Stand (SS-009): The distinction between sites SS-008 and SS-009 needs to be more clearly defined within this plan. The reference to the petroleum hydrocarbon contamination (23,900 mg/kg in BH8) exceeding ADEC cleanup levels within SS-008 (Waste Accumulation Area No.4, Old Sanitary Sewer System, Former Sewage Lagoon, and Former Paint Shop) needs to be removed from this proposed plan. As agreed upon in a meeting on December 2nd, further subsurface investigation will be conducted within this exceedence area. The NFA decision needs to incorporate site SS-009 only. Gretchen Pikul
2/18/1999 CERCLA Proposed Plan Proposed Plan for No Further Action: IRP Sites DP05, OT12, SS01, SS07, SS09, LF10, and OT06 (draft dated December 1998, final dated February 1999); ADEC internal briefings on December 10 and 21; ADEC comment letter dated December 24, 1998; comment resolution meeting dated January 11, 1999; public meeting on February 18, 1999. Lower Camp and Airstrip WAA No. 3 (SS-007). The human health and ecological risks at this site were below ADEC risk-management standards, indicating the site does not pose a risk. All detected contaminants were also below the ADEC-recommended cleanup levels. Recommended action: No Further Remedial Action Planned. Gretchen Pikul

1/17/2001 CERCLA ROD Approved 7 Decision Documents signed by ADEC on November 21, 2000, and by Air Force on January 17, 2001. Sites include OT012, SS001, SS007, LF010, OT006, SS009, and DP005. SS007 Decision Document has a no further action status. Institutional control in the form of notice in land records will be developed by the Air Force, with ADEC concurrence, for waste left in place and within a base master plan. Visual inspections of cover material will be conducted and documented over a 5 year period (the first, third, and fifth years) to check that no erosion of the cover is occurring. After the last inspection, a 5-year review will be conducted to review the results of the inspections. If the cover material has remained in good condition, no further inspections will be required. Due to the close proximity and similar historical activities of IRP Sites SS-007 and SS-009, the maintenance and inspection program for IRP Site SS-007 has been incorporated into the maintenance and inspection program for IRP Site SS-009. The selected remedy is protective of human health and the environment, complies with federal and state requirements that are legally applicable or relevant and appropriate, 'and is cost-effective. The statutory preference for treatment is not satisfied because treatment was not found to be necessary. Contaminant levels at the site have been determined to present no unacceptable threat to human health or the environment; thus, no treatment is necessary. This decision may be reviewed and modified in the future if new information becomes available which indicates the presence of previously undiscovered contamination or exposure routes that may cause a risk to human health or the environment. Jennifer Roberts

12/28/2005 Update or Other Action Five Year Review for IRP Sites DP-005, LF-010, OT-012, SS-001, SS-007, and SS-009. This is the first five-year review conducted at Site SS-007. The triggering action for the review is the signing of the Record of Decision (ROD) document for Site SS-007 on January 17, 2001. The five-year review is required because potentially hazardous debris or substances may remain buried at the site above levels that allow for unlimidted use and unrestricted exposure. Site SS-007 is the former location of a paint and oil storage building. Waste oils and other liquids, as well as, unused chemrical products have been stored at the site since the 1950s. Analytical results from the 1992 SI and the 1997 RI indicate that very low residual levels of organic contaminants were detected in soils beneath this site. The levels detected were all below human health and ecological risk-based levels presented in the Baseline Risk Assessments; however, no contaminants of concern or contaminants of ecological concernI were identified in the risk assessment for this location. In addition, levels of contaminants were below Alaska Department of Environmental Conservation (ADEC) cleanup standards in 18 AAC 75 regulations. Because no contam-inants of concern were found to exist at Site SS-007, it was determined that no further remedial action was required. This determination was found to be protective of human health and the environment and complied with applicable or relevant and appropriate requirements (ARARs) established for Site SS-007. To ensure the existing cover material remained intact, visual inspections were scheduled to be conducted and documented at Site SS-007 every other year for 5 years. The inspections3 were to verify that healthy vegetation existed and no erosion of the cover was occurring. If at the end of five years the cover material remained in good shape at Site SS-007, no further inspections would be required. Land use controls (also known as institutional controls) were evaluated by verifying their existence within the Tatalina Base General Plan and their location presented on the Tatalina Base Map. The institutional controls that are in place include restrictions on excavating and surface grading at the site. No activities were observed during the SI that would have violated the land use controls. The soil material cover covering the buried debris was intact, undisturbed, and has revegetated naturally. With the successful completion of this five-year review, no further five-year reviews are required for Site SS-007. If future land use changes or physical impacts to the landfill soil material covers have occurred, future five-year reviews may be required. Jeff Norberg
1/30/2006 CERCLA ROD Periodic Review Five-Year Review – Installation Restoration Sites DP-005, LF-010, OT-012, SS-001, SS-007, and SS-009; Final dated November 2005 received December 28, 2005; ADEC issued approval letter on January 30, 2006. The Alaska Department of Environmental Conservation (ADEC), Federal Facilities Oversight group, received the Five-Year Review of Installation Restoration Program Sites DP-005; LF-010; OT-012; SS-001; SS-007; and SS-009 Tatalina LRRS, Alaska (dated November 2005) on December 28, 2005. ADEC have completed our review and concur with the contents of this document, with the following exception. The Protectiveness Statement within Section 5.8 indicates that “no contaminants of concern exist at SS-001” and “there is no need for further remedial action.” As stipulated in the ROD for Site SS-001, “petroleum contaminated soil adjacent to the MAR facility has not been fully delineated due to the risk of compromising the structural integrity of the MAR facility. When the current MAR facility is decommissioned and removed in the future, the extent of subsurface contamination remaining beneath the building will be assessed to determine if remedial action is necessary.” Although summarized in Section 5.3, this information should also be emphasized in Section 5.8. Please note that the ADEC review and concurrence on this document is to ensure that the work is done in accordance with State of Alaska environmental conservation laws and regulations. While the ADEC may comment on other state and federal laws and regulations, our concurrence on this document does not relieve responsible persons from the need to comply with other applicable laws and regulations.

3/18/2015 Institutional Control Update One of several sites with Land Use Controls in effect (LUC Mgt Plan 2015 Pacific Air Forces Regional Support Center Installations, JBER, AK) March 13, 2015. In addition to ICs established as part of LUCs of the ERP for landfill sites with LUCs in effect, both ERP landfill & non-ERP landfill sites in Alaska under the management of PRSC must also comply with regulations set forth by the ADEC solid waste regulations in 18 AAC 60. Furthermore, landfill sites under the management of PRSC but not categorized as an ERP site must also comply with ADEC 18 AAC 60. Table 1-3 describes PRSC non-ERP landfill sites. Landfills are defined in 18 AAC 60 as “an area of land, or an excavation in which solid wastes are placed for permanent disposal, & that is not an application site, injection well, reserve pit, or waste pile.” This definition applies to most PRSC ERP & non-ERP sites in Alaska designated as landfills, dumps, or caches. Small PRSC ERP & non-ERP landfill sites at remote installations, such as the long-range radar stations, are regulated as Class III landfills as defined by ADEC. General requirements to manage landfills in place are established by ADEC & included in Table 2-2. However, alternative criteria can & often are adopted through negotiation with ADEC (see 18 AAC 60.900, Waivers). Post-closure notification requirements for Class III landfills, including notifications to ADEC & to potential future landowners, are summarized in Table 2-3. Tables 2-2 & 2-3 both generally assume the subject landfill is closed, has been reasonably well characterized, & a monitoring program for media of concern has been established & approved by ADEC.

The State of Alaska supports and concurs with the selected remedy of no further action. Visual inspections of cover material will be conducted and documented over a 5 year period (the first, third, and fifth years) to check that healthy vegetation exists and no erosion of the cover is occurring. After the last inspection, a 5-year review will be conducted to review the results of the inspections. If the cover material has remained in good condition, no further inspections will be required. The institutional controls that are in place include restrictions on excavating and surface grading at the site. Louis Howard
