Staff commented on the draft work plan (site investigation, sampling and analysis plan, quality assurance plan). Staff commented that 3 soil samples along a 3 mile long pipeline is insufficient to come to any conclusion regarding the contamination present or absent at the pipeline. Historically reported areas of contamination were found but the location is unknown and useless for directing current field efforts. Limited sampling (one sample) from doorways, landfills will not likely produce any data to lead to any kind of decision. Soil sample locations should be from original grade since many areas have been regarded during past remedial actions.

Staff commented on the draft site investigation report.
There are two areas that are not addressed in this section that need further investigation. During the EMCON aerial survey, conducted on October 27, 1994, drums were observed along the road which leads to Wide Bay. These need to be investigated to determine their origin and contamination threat. Also, during EMCON's interview with Abby Woodbridge, she mentioned radioactive warning signs in the composite building. Further research is warranted to ensure that any possible radioactive source was removed from the facility. |

SS002: LANDFILL NO. 1 AT THE FORMER COMPOSITE BUILDING
RECOMMENDATIONS
It is recommended that geophysics be used to better define the boundaries of the landfill. Additional analytical sampling should be performed to confirm that landfill cover soil and surface soil surrounding the landfill are uncontaminated. In addition, it is recommended that test
pits be excavated around the perimeter of the landfill so that the depth to bedrock and volume of
buried debris can be determined. The perimeter of the landfill should be re-surveyed.
To ensure the landfill is in compliance with ADEC Solid Waste Regulations 18 AAC 60, the
following recommendations are also made:
• Adequately backfill depressions and grade to promote drainage without erosion;
• Provide sufficient cover to prevent debris eroding from the landfill;
• Take proper precautions to ensure that asbestos fibers are not released to air or surface
water; and
Install asbestos warning signs. |

Meeting or Teleconference Held |
Stakeholders met for a 3-day Triad Systematic Planning meeting between July 18 and July 20, 2006 to discuss plans to address residual contamination at the former Driftwood Bay RRS facility. The primary purpose of this meeting was to reach an understanding of data quality objectives for each site at Driftwood Bay for eventual site closure and land transfer. Several sites identified as petroleum only, will be investigated in accordance with Alaska State regulations. The investigation and closure for remaining sites will comply with the Comprehensive Environmental Response, Compensation, and Liability Act. |

Document, Report, or Work plan Review - other |
DEC received a copy of a letter from EPA to the Air Force documenting EPA';s decision of No Further Remedial Action Planned under EPA's Superfund Program. This decision does
not preclude any further action at the site by another EPA program, the State or other Federal
agency.
EPA's NFRAP designation does not relieve your facility from complying with appropriate Alaska state regulations. 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.
If new or additional information becomes available suggesting that the site may warrant further evaluation, EPA will re-evaluate the site accordingly. |

Site Characterization Report Approved |
Contaminated Sites staff reviewed a site characterization report for the Driftwood Bay Radio Relay Station. The site had an upper site where the bill board antennae and composite building were located. The lower camp area contained the support facilities such as the airstrip and fuel tank farm. Several areas have contamination over method 2 cleanup levels. A risk assessment is being done to assess pathways and risk for those areas. The report had quality assurance problems with lab analytical data mostly concerning spiking errors for the surrogates in volatiles |

Meeting or Teleconference Held |
Contaminated Sites staff met with the Air Force 611 and their contractor on the Driftwood Bay Long Range Radar Site. The meeting was to discuss comments on the draft site characterization report. All issues were resolved with exception of how to flag volatile organic carbon data with surrogate quality control errors. The contractor made a good argument that the data shouldn’t be rejected; however the state is bound by the National Functional Guidelines for data criteria. We will continue discussion whether the Air Force can use a modified flag so the data can still be used as a screening tool |

Meeting or Teleconference Held |
Contaminated Sites staff participated in a comment meeting on the draft risk assessment for the former Driftwood Bay Radio Relay Station. There is ecological risk for various species at three sites from lead and Polycyclic Aromatic Hydrocarbons (PAHs) well over acceptable state risk levels. One site is a landfill where ash was sampled from a test pit. One site is a former POL tank farm near the coast and another site is an electronic debris area with elemental lead from battery carcasses on the ground surface |

Update or Other Action |
In 1991, the US Army Corps of Engineers, under the Formerly Used Defense Site (FUDS) Program, contracted with Anderson Excavating and Wrecking Company to demolish buildings and cleanup solid wastes at the site. The composite building, POL pump building, airport storage building, ammunition building, water pump house, lighting vault, four billboard antennas and other wastes were demolished and buried in an on-site landfill south of the former composite building. Concrete foundations were left in place. The Corps hired Environmental Management to remove the above and underground fuel storage tanks and pipelines, which were cut up and disposed in the on-site landfill. A total of 350 55-gallon drums were removed. Fuel contaminated soil was excavated, thermally treated and disposed of in the landfill. A 55-gallon drum of PCB and a drum containing lead acid batteries were removed from the site for proper disposal. Subsequently, it was determined that the Air Force still controls the site as the public land withdrawl has not been relinquished. Further cleanup work on the site is not eligible under the FUDS Program.
DEC and the Corps have signed a Containerized / Hazardous, Toxic or Radiologiacl Waste (CON/HTRW) Project Closeout Report (Aug. 2009) documenting no additional CON/HTRW work is eligible under the FUDS Program. The USAF is responsible for remaining environmental restoration work at the site. |

Meeting or Teleconference Held |
Contaminated sites staff participated in an update meeting with project managers from the USAF 611th and their contractor. Discussion included the proposed timeline and scope of work for the 2010 and 2011 field seasons for installing monitoring wells and institutional controls at 4 POL sites and the status of 8 other sites (5 are proposed to be DEC-determined as cleanup complete with no further action; 3 sites are being addressed under CERCLA). |

CERCLA Remedial Design/Remedial Action Plan Approved |
Final Remedial Action Work Plan received.
Activities at SS002 in 2015 are limited to institutional controls (ICs) and inspection to ensure ICs have been implemented, per the final USAF scope of work. ICs at SS002 will include grading of the landfill cover with additional material placed, as necessary, to ensure proper landfill cell
coverage (minimum of 2 feet) and to promote runoff while minimizing erosion and infiltration, as well as ensuring that ACM are sufficiently covered to prevent the release of fibers to the air or surface water.
The ICs will also include LUCs which will be incorporated into the 611th CES LUC Management Plan, as needed, to indicate the presence of a closed and permitted landfill with ACM cell, as well as compliance with 18 AAC 60 maintenance and inspection requirements. A Notice of Environmental Contamination will be placed in the Alaska Department of Natural Resources’ land records by the USAF. ICs will also consist of warning signs posted at SS002, in compliance with Title 40 Code of Federal Regulations (CFR) Section 61.154(b), at the extent defined in the 1991 Landfill Closure Report (USACE, 1996) of the landfill boundaries to implement this LUC. Four signs will be placed at the site. |
Debra Caillouet |
| 4/12/2016 |
Update or Other Action |
Draft ICs report received for review and comment. ICs at Site SS002, SS007, and Site SS010 consists of the following:
1. Land Use Controls for each site are incorporated into the 611th Civil Engineering Squadron Land Use Control Management Plan.
2. A Notice of Environmental Contamination will be placed in the Alaska Department of Natural Resources’ (ADNR’s) land records.
3. Warning signs placed at the boundary of each site will provide contact information for Land Use Control Management.
No issues were found during the 2015 IC inspections at Driftwood Bay RRS Sites SS007 or SS010 that would require additional corrective action or changes to the IC Plan for the sites.
Maintenance to the cover of the landfill at Site SS002 should be pursued to correct cover
subsidence and address debris protruding through the cover to limit the hazard to recreational
land users and wildlife. |

Institutional controls report received for review and comment.
ICs at Site SS007 (Petroleum, Oil, and Lubricants [POL] Tank Farm) and Site SS010 (Water Supply Pump House) are part of the selected remedy for Driftwood Bay RRS for each of the respective sites. Final remedies were presented for SS007 and SS010 in the 2009 Site Characterization Report for Driftwood Bay RRS (USAF, 2009). Site SS002 (Composite Building Landfill) consists of a permitted and closed demolition debris landfill. ICs for SS002 are part of the long-term post-closure management strategy for the site.
On 11 June 2016, seven monuments were located that demarcate the extent of the demolition debris
land fill (SS002). Site personnel collected photographs from each monument to depict the
condition of the landfill cover. The landfill monuments were in good condition. The asbestos cell
was located based on the maps provided in the 1996 Preliminary Assessment and Site Investigation
(PA/SI – USAF, 1996). No asbestos warning sign was present at the location.
Additionally, the subsidence reported in the 1996 PA/SI at the location of a buried water cistern remains present at SS002. The holes could potentially pose a hazard to land users. Recreational land users (all-terrain vehicle users) were observed at the site in 2015, as well as wildlife (fox). Several areas of erosion relating to overland ephemeral channels were observed in several areas.
Debris, presumably sourced from the landfill, were photographed in several areas either protruding the landfill cover or deposited surficially. The majority of the landfill cover is free of vegetation. Warning signs, installed in four locations at the extents of the landfill in 2015, remain in good condition.

Staff commented on the Draft RA – O/LTM WP Addendum for Driftwood Bay RRS, Alaska dated August 2017. Photos will be taken at each of the source areas to demonstrate compliance with institutional controls and document site conditions. This will be in addition to filling out the Land Use Control form. Not only should photographs be taken of ineffective LUC measure, landfill cap failures or potential contaminant releases, but photographs should also be taken to show effective LUC measurers, landfill cap conditions, and no contaminant releases surrounding the landfill. |

Update or Other Action |
This is the first Five-Year Review (FYR) for Sites SS002, SS007, and SS010 at Driftwood Bay Radio Relay Station (RRS), Alaska. The USAF has determined that the remedy at Site SS002 is not protective of human health & the environment due to noted deficiencies in the landfill cover. Debris is protruding through the cap, & subsidence & erosion have been documented. The landfill cover requires corrective action in order to restore the protectiveness of the SS002 remedy. However, ICs are in place to minimize exposures to onsite contaminants & warning signs are present at the site. In order for the remedy to be protective in the long-term after correction of these deficiencies, a NEC must be filed in the ADNR’s land records to ensure protectiveness. Milestone Date: 12/29/2017.

Update or Other Action |
Draft Remedial Action Operations/LTM report received for review & comment. The landfill cap at SS002 was observed to be in fair condition. One of the LUC signs was missing from its post & appears to have blown away after the hardware (nuts, bolts, & washers) holding the sign on the post rusted through. The other signs were standing & visible, however the hardware (nuts, bolts, & washers) are deteriorating & not made of stainless material & would warrant replacement before the signs fall off. All of the sign posts are heavily rusted but the posts are made of heavy gauge steel & do not warrant immediate replacement.
There was no standing water observed at the site, & vegetation was relatively sparse in comparison to the surrounding area. Exposed portions of liner material were not observed, however various metal debris remains scattered around with some of the pieces protruding from within the landfill. Site observations during past inspections have indicated the presence of occasional recreational land users, & wildlife. It is recommended that the metal debris be removed & that the pieces protruding from within the landfill be cut-off below the grounds surface.

DEC received and reviewed the Draft Final UFP-QAPP for Long Term Management Activities, Driftwood Bay Radio Relay Station, Alaska, dated March 2021. Comments send by ADEC on June 14th, and RTC and redline received on August 9th. The work plan describes the USAFs intent to collect groundwater samples from six wells at SS007 to determine whether trends indicate continued natural attenuation is occurring; conduct a review of institutional controls (ICs) at all sites (LF006, SS002, SS007, SS010, and WP003), and conduct a landfill cap inspection to ensure land use controls (LUCs) currently in place are effectively reducing potential exposure. SS010, SS002, and SS007 have NECs recorded at the sites documenting that cleanup have been performed to the maximum extent practicable even though residual fuel contaminated soil and/or solvent contaminated groundwater exists on site, however the 2021 sampling of SS007 is intended to demonstrate the site has reached UU/UE and can be closed without ICs. The report and RTC was approved on this date. |

Institutional Control Update |
The 1991 Landfill has no monitoring components and is only subject to annual LTM inspections to document on-site LUCs/ICs (landfill cover and warning signs) remain in place and are effective to prevent exposure to landfill debris, including asbestos containing material. Site SS002 has not had a formal decision document, therefore no IC details are added to the site. |

On this date, DEC reviewed and approved the Final 2022 Five-Year Review for Sites SS002, SS007, SS010, and WP003 at Driftwood Bay Radio Relay Station, Alaska. This is the 2nd FYR for SS002, SS007, and SS010, and the first FYR for WP003. During this FYR period, LF006 was closed without institutional controls and is no longer subject to FYRs. An Environmental Covenant or Notice of Activity and Use Limitations (NAUL) is required to be placed on the WP003 site to maintain the institutional controls (ICs) identified in the 2018 IC Plan, with a milestone date of this year (2023). The ICs will need to document restrictions to groundwater and soil use.
Additionally, because none of the sites included in this FYR have an official Decision Document, DEC recommended a Decision Document(s) be drafted to document the official ICs and remedies in place at the four sites. Currently, ICs are functioning as intended and there is no current exposure.
