Problems/Comments

Groundwater Zone 2 (OT28). Refueler shop, Building 149 (SS21). The site is located approximately 2,000 feet north of Runway 29 and adjacent to the KSA flight line. The area was used for the storage and maintenance of tanker trucks used to fuel aircraft. The contamination at SS021 is associated with USTs at Buildings 157/159. A Record of Decision for Final Remedial Action (signed by ADEC in December 2002, and awaiting Air Force signature) records this site as closed, with transfer to the 611th Civil Engineering Squadron Compliance Section under regulatory oversight by ADEC’s Storage Tank Program. The components of the final remedy consist of: continuation of bioventing, implementation of institutional controls, annual long-term monitoring with a 5-year review, and soil sampling to confirm that cleanup levels have been achieved. **Site double listed** LUST (2569.38.022.04)and CSP (2569.38.016.04) AF point of contact: Charley Peyton, Project Manager, 611th CES/CEV 10471 20th Street Suite 338, Elmendorf AFB, AK 99506-2270; Telephone 907-552-9765.

12/18/2002 Leaking Underground Storage Tank Corrective Action Underway The Record of Decision for Final Remedial Action at Groundwater Zone OT028 (Zone 2), Waste Accumulation Area 3 (SS017), Eskimo Creek Dump (SS022), Refueler Shop (SS021), and Old Power Plant Building (SS020) was signed by ADEC on December 18, 2002. The selected final remedies include: monitored natural attenuation of the TCE, BTEX, and GRO plumes with annual sampling, institutional controls on drinking water wells, and a 5-year review for OT028; site closure for SS017; vegetative soil cap, annual long-term monitoring (LTM), institutional controls on excavations and other subsurface activities, and 5-year review for SS022; and transfer to UST compliance section for continued operation of bioventing systems since contamination is associated with former state-regulated USTs, annual LTM, institutional controls of excavations and other subsurface activities, 5-year review, and confirmation soil samples to obtain site closure for SS021 and SS020. The 350 determination has been granted for the A-Aquifer, with application of the 10x rule for soil and groundwater. This approval has been given for similar facility sites (Zones 1 and 4) in recent years and documented in final, signed RODs. Gretchen Pikul

10/17/2016 Document, Report, or Work plan Review - other ADEC provided comments on the "Closure Report for Nine Compliance Restoration Program Sites (TU/US-C519, TU/US-C517, TU/US-C518, TU/US-C520, TU/US-C522, TU/US-C523, TU/US-C524, TU/US-C589, TU/US-C592) at the King Salmon Divert". Site TU/US-C523 is included in the CS database as two individual sites, an active LUST site (Haz ID: 23354 “King Salmon Air Station SS21 Refueler Shop”) and a closed (Cleanup Complete) CSP site (Haz ID: 506 “King Salmon Air Station SS21”). Based on our research, this site is closed with Institutional Controls (ICs) (bioventing, land use controls, annual inspections, 5-year review) and was inaccurately closed without ICs in the database. Once this report is finalized, ADEC will close (Cleanup Complete) the LUST site and update the CSP site to closed (Cleanup Complete with ICs). IC documentation will be tracked in the CS database CSP site Haz ID: 2629 “King Salmon AS OT028 GW Zone 2”. Holly Weiss-Racine
3/22/2017 Cleanup Complete Determination Issued Review of Closure Report for Nine Compliance Restoration Program Sites TU/US-C519, TU/US-C517, TU/US-C518, TU/USC520, TU/US-C522, TU/US-C523, TU/US-C524, TU/US-C589, and TU/US-C592 at King Salmon Divert received for review. Staff commented and agreed that the site warrants cleanup complete without ICs for CS DB Hazard ID 23354 which will be administratively closed out. All follow-up monitoring and necessary remediation will be assigned to CS DB Hazard ID 506 aka King Salmon Air Station SS21. Louis Howard
