KANG Drainage Study received.
Recommendations
A new storm sewer should be constructed. The drainage ditch should be regraded between Nodes
H and L in Basin IV. We recommend that steam thaw pipes be installed in culverts in major drainage ways. As a general drainage scheme, large ditches (such as extend around the flight line) are very effective in that they provide an area for winter snow disposal which readily drains during break-up. We recommend that the culvert inlet at Node R be modified such that the large drainage ditch around the perimeter of the flight line in Sub-basin IV-E could serve as a surge basin.
Low areas and swamps which exist in undeveloped areas of the study area provide a natural solution
to runoff water quantity and quality problems. New facilities should provide 515 cf runoff storage
at Node A in Sub-basin IV-A. In sidehill areas, ditches constructed in kiess silt should be lined with gravel or rock to protect the invert from erosion. At the outlet of Basin V a cutoff ditch should be constructed to capture future overland flow. A culvert should be installed in the perimeter road at the outfall of Basin II.

Base Master Plan received.
The major goal of the Kulis Air National Guard (ANG) Base Master Plan is to identify opportunities for improving the mission capabilities, readiness, and environment of Kulis ANG Base and the 176th Group. Results of these initiatives are expected to enhance the base's image as an excellent installation to support airlift, rescue, and training requirements into the next century. This plan looks forward 20 years and provides a framework for daily decision making in regard to facility needs and sitings. This plan is a tool used to achieve the base objectives and goals that have been established as necessary to mission fulfillment. As a tool, this plan must be reviewed and updated on an annual basis to keep the plan abreast of changing needs and goals.
Outlined in this plan is the mission expansion from the existing 16 aircraft to a long-range mission of 30 aircraft. To fulfill this mission, short- and long-range installation plans have been developed in a manner that will maximize mission accomplishment, optimize existing facilities, and provide the most efficient and professional environment possible.
The existing total land area of 129.47 acres is leased from the AlA. Significant potential still exists for future development within the existing installation boundary.

EA for Proposed short term construction projects at KANGB.
This environmental assessment (EA) evaluates potential environmental impacts associated with proposed short-term construction projects at Kulis Air National Guard Base (ANGB). The purpose of the proposed action is to implement eleven short-term construction projects that are critical for maintaining efficient base operations and enhancing the orderly development of Kulis ANGB. These projects are needed to consolidate common or compatible organizational and facility uses to maximize land use compatibility and facility efficiency. Implementation of the proposed action would help accomplish this by providing enhanced development, thereby reducing existing facility utilization inefficiencies and circulation problems at Kulis ANGB.
The primary goal of the proposed short-term construction projects at Kulis ANGB is to improve the unit's mission capabilities and readiness in order to support airlift, rescue, and training requirements. In order to meet these requirements, eleven construction projects, including the expansion of the existing apron/taxiway and the demolition of four facilities would be implemented and completed within the next 5 years. Proposed demolition is necessary in order to replace outdated facilities or to facilitate new construction. New facilities would be located in areas more compatible from a land-use efficiency perspective.

Environmental Baseline Study received.
The majority of the 129-acre property of Kulis ANGB proposed for transfer is classified as a Category 1 site (i.e., areas with no releases of hazardous substances) and will be referred to as one site. Smaller areas within the property boundaries have been separated from this classification as follows: eight (8) Category 2 sites (i.e., areas with only petroleum releases), no Category 3 sites (i.e., areas with releases that do not require remediation), four (4) Category 4 sites (i.e., areas where releases have occurred and all remedial actions have been completed), one (1) Category 5 site (i.e., areas where releases have occurred and all remedial actions are underway), no Category 6 sites (i.e., areas where releases have occurred, but remedial actions have not been implemented), and no Category 7 sites (i.e., areas requiring further investigation). These specific sites are listed as follows:
• Category 1 Sites—The 129- acres of Kulis ANGB property (except as noted below).
• Category 2 Sites—Buildings 00002 (Helicopter Maintenance); 00014 (Refueler Parking Canopy); 00023 (Supply & Equipment Warehouse - parking lot); 00046 (Corrosion Control Facility); 00047
(Aerospace Ground Equipment); east of 00050 (Civil Engineer Squadron); and Former Refueling Station (year 2000 location); Roundabout Road (southern intersection with Denali View
Drive).
• Category 3 Sites—None identified.
• Category 4 Sites—Site 00117, A.K.A. Site 1; Site 00012, A.K.A. Site 2; POL Yard (specifically footprint of former ASTs 1, 2 and 3; Aircraft Parking Apron.
• Category 5 Sites—Building 00042 (Fire Rescue Station).
• Category 6 Sites—None identified.
• Category 7 Sites—None identified.
Corrective actions are recommended as follows to eliminate items of concern:
• Base personnel have indicated that the closure report has been submitted to ADEC, however, the site is not officially closed until approval is received from the state. Once the site has been closed by the state, this will no longer be an item of concern.
• Based on the assumed use of the buildings (airport administration), corrective actions are not needed at this time. Future owners/occupants should be aware that the older buildings might contain lead-based paint. If the paint begins to deteriorate or if children will frequent a building, the paint should be tested.
No further study or assessment of the surveyed parcels is recommended at this time. Therefore, it is recommended that the planned property transfer proceed as proposed.

CERCLA PA |
Preliminary Assessment received.
This Perfluorinated Compounds (PFCs) Preliminary Assessment (PA) provides findings from research conducted to determine whether and where aqueous film forming foam (AFFF), containing PFCs, was stored, handled, used or released at the former Kulis Air National Guard Base (ANGB), located in Anchorage, Alaska. Research was conducted for the years 1970 through the installation closure in 2011 using: 1) personnel interviews; 2) online research; and, 3) archival research at the Air Force Historical Research Agency (AFHRA) and the Air Force Safety Center (AFSEC).
AFFF, containing PFCs, was used at the former Kulis ANGB for extinguishing petroleum fires and in fire suppression systems at several of the installation buildings. Based on the research conducted, ten potential AFFF areas were identified 1 at former Kulis ANGB and may potentially require further action.
Building 2 (Helicopter Maintenance), Building 3 (Aerial Port and Hangar), Building 9 (Former Vehicle Maintenance/Fire Station), Building 42 (Fire Rescue Station), Building 45 (Fuel Systems Hangar), Roundabout Road, Building 1005 (Fire Rescue Storage), T-1003 or T-1004, North Aircraft Apron, West Aircraft Apron.

Draft Installation-Specific Uniform Federal Policy – Quality Assurance Project Plan Addendum
Site Inspection of PFC Release Areas at Multiple BRAC Installations: Former Kulis Air National Guard Base received for review and comment.
The primary objective of the SI at the former Kulis ANGB is to conduct an investigation of AFFF Areas 1 through 10 (Figures 2, 3, and 4), previously identified as part of the PA (AMEC Foster Wheeler Environment and Infrastructure, Inc. [AMEC], 2016) to
determine if PFCs are present in groundwater, soil, and/or surface water, determine if concentrations of PFOS, PFOA or a sum of both in groundwater, exceed 0.07 micrograms per liter (µg/L).
identify potential human health pathways and receptors, and
where there is a reasonable expectation that PFCs may be present, determine if drinking water wells are impacted.
While not listed on the NPL, Kulis ANGB must follow CERCLA process per E.O. 12580 [e.g. CERCLA Sections 104(a), (b), and (c)(4), 113(k), 117(a), and (c), 119, and 121) with respect to releases or threatened releases where either the release is on or the sole source of the release is from any facility or vessel under the jurisdiction, custody, or control of their departments.

Final Quality Program Plan for Site Inspection of Potential Perfluorinated Compound Release
Areas at Multiple BRAC Installations Contract No. FA8903-08-D-8785 Task Order No. 0017 received along with site-specific UFP QAPP Addendum for field work on PFCs at the former facility.
Perfluorinated Compound (PFC) Release Areas at Multiple Base Realignment and Closure (BRAC) Installations. This is a general QPP designed to provide program-level information for investigation and release determination activities at Aqueous Film Forming Foam (AFFF) areas that will be conducted at 17 United States Air Force (USAF) BRAC installations including Kulis ANGB.
The primary objective of the SI is to conduct investigations of potential AFFF areas previously identified in the PA conducted across 17 BRAC installations to
1. determine if PFCs are present in groundwater, soil, surface water, sediment, and/or other
environmental media as necessary,
2. determine if concentrations of PFOS, PFOA or the sum of both exceed 0.07 µg/L in groundwater,
3. identify potential human health receptors and pathways, and
4. where there is a reasonable expectation that PFCs are present, determine if drinking water wells are impacted.
State-specific screening criteria or action levels for PFCs will be included in the Installation-Specific UFP QAPP Addenda as appropriate. Background samples are not proposed to be collected during SI activities. However, if results of the field sampling program indicate that additional investigation is warranted, then background sampling will be conducted during the remedial investigation as appropriate. Inhalation has not been identified as a potential exposure pathway for PFCs; therefore air sampling will not be conducted.
The SI field investigations will be documented in Installation-Specific SI Reports, which will include revised conceptual site models (CSMs), exposure pathways and potential receptors, and an evaluation of data at each AFFF area and recommendations for
• no further action,
• remedial investigation, or
• implementation of mitigation measures (time critical or non-time critical removal action).

Document, Report, or Work plan Review - other |
Staff reviewed the Draft Installation-Specific UFP-QAPP Addendum SI of PFCs releases.
Main comments were regarding the need to complete ecoscoping forms on the seven areas being investigated for PFCs and that ADEC has calculated cleanup levels for PFOS and PFOA that are lower than the AFCEE/TDV soil screening levels being proposed for use. Finally, staff requested that soil borings be sampled at 0-2' bgs and 13'-15' bgs instead of 0-2' and 10-12' bgs and that well surveys include researching of information from ADEC's Drinking Water Program, Municipality of Anchorage's On-Site Water & Wastewater Program as well as Alaska Department of Natural Resources Well Log Tracking System (WELTS).

Site Characterization Workplan Approved |
On July 28, 2016, ADEC received the response to comments for the “Installation-Specific UFP-QAPP Addendum Site Inspection of PFC Release Areas” work plan. ADEC conditionally approves the responses to comments and the UFP-QAPP may be finalized. The PFOS/PFOA cleanup levels (included in the Draft work plan) used by AFCEC, to determine presence or absence, are greater than what ADEC will be adopting into 18 AAC 75 this fall/winter 2016 [actually on 11/06/2016].
The PFOS and PFOA cleanup levels in the draft 18 AAC 75 regulations will be used by ADEC staff when reviewing the report for the PFC inspection at the Former KANGB. If the levels of PFOS and PFOA detected at the site exceed ADEC cleanup levels listed in 18 AAC 75 (as revised), then ADEC will require additional work delineating the nature and extent of contamination. Proceeding with the work using the higher screening levels or presence/absence thresholds than ADEC’s draft cleanup levels is at AFCEC’s risk. |

Letter work plan addendum received and approved by ADEC for implementation
The proposed supplemental investigation activities include the following:
1) Installation of five groundwater monitoring wells to better define groundwater flow directions
and concentrations of PFCs that may be migrating on or off-site. The attached Figure 1 illustrates the proposed well locations. Well depths will correspond to first water encountered,
historically 75-85 feet below ground surface (bgs). Boreholes for each well will be advanced
to penetrate up to five feet into the top of the reported confining clay layer beneath the former
ANGB or determine if the confining unit is absent. The borehole will be backfilled with
bentonite to the top of the clay and the monitoring well set above the confining clay layer.
Based on lithologic observations from new monitoring wells KULPMW 0l0, -11, -13, and 14, if the confining clay unit is absent along the former eastern boundary, monitoring well KULPMWO 12 will be advanced and installed to depths up to 140 ft bgs. All well screens will be 10 feet long. Each new monitoring well will be surveyed by a professional land surveyor to determine top of casing elevation to support potentiometric mapping.
2) Groundwater samples will be collected from each of the nine monitoring wells installed in
2016 to confirm previous results as well as the five newly installed wells. Samples will be
analyzed for PFCs on an expedited turnaround time. One of the duplicate samples will be
collected from well KULPMW007.
3) Collect a complete round of water levels from the 14 wells (nine existing and five new) to
determine groundwater flow direction.
4) The drainage ditch along the south side of Tug Road (Figure 1) will be visually investigated to
determine potential contributions and discharge points. |

Document, Report, or Work plan Review - other |
A letter was sent regarding the 2018 ADEC tech memo which establishes drinking water action levels for six PFAS when detected in groundwater or surface water used for drinking at Former Kulis Air National Guard Site. The tech memo establishes drinking water action levels for six PFAS when detected in groundwater or surface water used for drinking. These compounds, selected in accordance with the U.S. Environmental Protection Agency’s third Unregulated Contaminant Monitoring Rule (UCMR3) under the Safe Drinking Water Act, include: perfluorooctane sulfonate, also known as perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid, also known as perfluorooctanoate (PFOA), perfluorononanoic acid (PFNA), Perfluorohexanesulfonic acid (PFHxS), Perfluoroheptanoic acid (PFHpA), and perfluorobutane sulfonate (PFBS). Based on review of available information, DEC considers these six UCMR3 compounds to be hazardous substances under state law.

Document, Report, or Work plan Review - other |
Staff sent a letter notifying Air Force of Action Levels for PFAS in Water and Guidance on Sampling Groundwater and Drinking Water Technical Memorandum dated August 20, 2018. Action levels for UCMR3 PFAS compounds in groundwater and surface water used as drinking water are as follows: Where one or more of the PFAS compounds, PFOS, PFOA, PFNA, PFHxS, or PFHpA are detected in a water sample analytical result, the sum of the concentrations for all detected compounds will be compared to an action level of 0.07 µg/L. Where PFBS is present in a water sample analytical result, the detected concentration will be compared to an action level of 2.0 µg/L. Please note that all future sampling results for PFAS-impacted groundwater, surface water, and pore water must include results for all six UCMR3 PFAS compounds.

Meeting or Teleconference Held |
Teleconference held with Air Force project manager regarding sampling of drinking water wells adjacent to former KANGB site. Upper level management review of the site was conducted and the result was not to continue with adding additional monitoring wells at the site, but instead to concentrate on the drinking water well sampling in the easterly direction within a one mile radius of the site.
A contractor will be chosen by Fall 2019 timeframe and coordination with ADEC staff will be forthcoming on the sampling design issues and public outreach before, during and after of the proposed drinking water wells.

Workplan Requested |
Staff requested the U.S. Air Force sample potable water wells potentially impacted by contamination from KANGB that were identified in the “Final Site Inspection for Aqueous Film Forming Foam Areas at Former Kulis Air National Guard Base” dated March 2019 (the SI). ADEC is concerned the sampling of the wells identified in the SI has not yet occurred, and receptors are potentially exposed to unacceptable levels of PFOA/PFOS. As of August 6, 2019, the U.S Air Force indicated it plans to sample the wells for PFOA/PFOS in April 2020. ADEC requests the U.S. Air Force sample the wells for PFOA/PFOS as soon as possible. |

Update or Other Action |
[Drinking] Water Well Survey to Supplement the Site Inspection of Per-& Polyfluoroalkyl Substance (PFAS) Release Areas received for review & comment. The well survey will focus on the eastern residential area adjacent to the former Kulis Air National Guard Base (ANGB) base boundary. Although this area appears to be upgradient of the contaminated AFFF Areas identified in the NE corner of the former ANGB in the SI, there is uncertainty regarding groundwater flow direction & properties are less than 100 feet from the base boundary. The well survey & sampling drinking activities will determine if active water wells are located on these properties & if PFOS & PFOA are present in drinking water.
The Air Force will provide ADEC with updates on the responses to well survey forms, door to door survey, & sampling as necessary. If sampling is performed, drinking water sample results will be supplied to the well owners in individual letters after data have been validated. The results will also be provided to ADEC with recommendations for additional sampling as necessary.

Document, Report, or Work plan Review - other |
Staff provided comments on the water well survey at the former Kulis Air National Guard Base (FKANGB). Main comments were to request further sampling of water wells to the south as well as the proposed east side of the FKANGB boundaries. ADEC will require that future sampling of drinking water wells will encompass a one mile radius of the site for PFAS contamination. Sampling, analysis and reporting of PFAS contamination will be required for all analytes of the Method 537.1 rev. 1.1/537.1 and not just the 14 proposed in the letter work plan. Finally, ADEC will require the use of updated regulations, updated or new guidance documents that are now in effect since the UFP-QAPP work plan was finalized in 2016.

Meeting or Teleconference Held |
DEC staff met with the U.S. Air Forces' (USAF's) representative to discuss the draft "Relative Risk Site Evaluation" (RRSE) completed by the USAF for CAT56P, due to the presence of PFOA and PFOS. The RRSE is used by the USAF to help prioritize its sites for work, based on risk. Kulis has an "overall site category" of "high" because there is unrestricted access to contamination in soil, and there are drinking water wells within four miles downgradient of known groundwater contamination. Sampling to date has not located any drinking water wells are impacted. |
