Problems/Comments

There are two areas of concern at the Bartlett Cove site, the Former Tank Farm site and the Utility Building site, located approximately 500 feet apart. The Former Tank Farm site had multiple underground storage tanks (USTs) used to store diesel and gasoline. Based on inventory control data, a loss of approximately 20,000 gallons of gasoline was reported in 1980. A quantity of diesel was also released, but the amount and date of the release is unknown. The Utility Building site included a power plant and generators. In 1991, approximately 3,000 gallons of diesel fuel spilled from a leak in the fuel return line beneath the generator floor slab. Initial site characterization activities in 1992 identified soil and groundwater contamination at both sites. The USTs at the Former Tank Farm were decommissioned in 1999, and replaced by the current UST system at the Utility Building site. Approximately 3,000 cubic yards of petroleum contaminated soil was excavated and incorporated into asphalt when the USTs were removed. Air injection/vapor extraction systems were installed at the Former Tank Farm site and the Utility Building site in 2000 and operated until 2011. Annual groundwater monitoring continues at this site.

4/4/2017 Document, Report, or Work plan Review - other DEC has approved by letter sent electronically today to the National Park Service, Alaska Region, Work Plan Bartlett Cove Former Tank Farm and Utility Building (Plan), dated March 29, 2017. Ahtna Engineering Services LLC completed the workplan for planned well installation and sample monitoring at the referenced Site in accordance with 18 AAC 78.260. In order to achieve the objectives listed in the Plan, Ahtna will perform the work at the FTF and UB sites in two phases. The first phase of well installation will occur in April 2017, and the second phase of groundwater monitoring will take place in June, 2017. Bruce Wanstall
7/13/2017 Update or Other Action Project Manager changed from Wanstell to Caudill Gretchen Caudill
11/22/2017 Document, Report, or Work plan Review - other Approved Final 2017 Monitoring Well Installation and Groundwater Sampling Report for Bartlett Cove Former Tank Farm and Utility Building. The report details the installation of two new monitoring wells coupled with soil analyses from the installation borings and the groundwater monitoring of new and established wells. The results of the soil sample collected at MW22 documented GRO,DRO, xylenes and PAHs above cleanup levels in soil at 17 feet below ground surface (within the smear zone). The groundwater monitoring documented the continued presence of DRO and PAHs above cleanup levels on the north side of both the Former Fuel Tank Farm and Utility Building. Total aromatic hydrocarbons (TAH) and total aqueous hydrocarbons (TAqH) were also documented above cleanup criteria in the monitoring well located closest to Bartlett Cove. A Mann-Kendall analysis indicates that none of the monitoring wells analyzed showed an increasing trend of contamination. DEC concurs with the recommendations to continue groundwater monitoring for DRO, PAHs, TAH, and TAqH, with the addition of volatile organic compounds (VOC) sampling. Archaeological resources in the area prevent the excavation of contaminated soils. Gretchen Caudill
4/16/2018 Document, Report, or Work plan Review - other DEC Approval - 2018 Groundwater Sampling Work Plan Bartlett Cove Former Tank Farm and Utility Building. This work plan details the continued groundwater monitoring at the Former Fuel Tank Farm and the Utility Building with the objectives of evaluating groundwater flow; monitoring and evaluating natural attenuation parameters in groundwater; assessing diesel range organics, fuel-related volatile organic compounds, and polycyclic aromatic hydrocarbons in groundwater; and evaluating the potential impacts to surface water by calculating total aromatic hydrocarbons and total aqueous hydrocarbons. Evaluation of lead is an existing data gap at the site and will need to be included in future field efforts. Gretchen Caudill
10/30/2018 Document, Report, or Work plan Review - other DEC Comments – 2018 Report for Groundwater Sampling, Bartlett Cove Former Tank Farm and Utility Building. The report documents DRO, VOC, and PAH contamination above cleanup levels still present in groundwater at the FTF site. Groundwater in two wells at the FTF also exceeded TAH and TAqH surface water quality standards in close proximity to the Bartlett Cove coastline. A Mann-Kendall analysis preformed indicates that none of the monitoring wells analyzed showed an increasing trend of contamination, however a trend was unable to be detected at two monitoring wells. DRO concentrations at the UB site remain in excess of cleanup levels at 35,000 µg/L and LNAPL is present in one well. One well showed a stable Mann-Kendall trend, however trends were not detected in all other wells at the UB site. Gretchen Caudill
1/3/2019 Document, Report, or Work plan Review - other DEC Approval - 2018 Report for Groundwater Sampling at Bartlett Cove Former Tank Farm and Utility Building Gretchen Caudill
5/3/2019 Document, Report, or Work plan Review - other DEC Comments provided on 20119 Groundwater Monitoring Work Plan. DEC requested metal analysis in groundwater to account for potential leaded gasoline release in 1980. Gretchen Caudill
1/7/2020 Meeting or Teleconference Held DEC met with NPS and Ahtna contractor to discuss site history and future plans for the site Tim Sharp
1/13/2020 Document, Report, or Work plan Review - other DEC Approved 2019 Final Report for Groundwater Monitoring. Recommended moving partially to biennial monitoring, with less stable trending wells or wells with LNAPL present continuing to be monitored annually. Lead will be sampled for at the FTF site in 2020 barring evidence of historical sampling that shows concentrations below cleanup levels. Tim Sharp
4/21/2020 Site Characterization Workplan Approved DEC Approved the Final 2020 Work Plan for groundwater sampling at the FTF and UB sites. Objectives for the project include evaluating groundwater flow direction, evaluating natural attenuation parameters, collecting samples for analysis of DRO, VOCs, PAHs, and total and dissolved lead at both sites. Surface water impacts will also be assessed by calculating TAH and TAqH concentrations from each sampled well. The work is scheduled to occur in mid July, but due to the current COVID-19 pandemic this is subject to change. Tim Sharp
10/30/2020 Document, Report, or Work plan Review - other DEC provided comments for the Draft 2020 Groundwater Sampling Report. At the FTF site, VOCs exceeding cleanup levels included naphthalene, 1,2,4-trimethylbenzene, and 1,3,5-trimethylbenzene in three wells. Two of these wells also showed DRO above cleanup levels, and one showed an additional exceedance of 1-methylnaphthalene. The report recommends that these wells be sampled annually, while others will be sampled every three years starting in 2022. At the UB site, two wells had naphthalene and DRO exceedances. Concentrations in UB-B12MW indicated potential presence of LNAPL. Three wells at the UB site will continue to be sampled annually, while others are scheduled to be sampled next in 2022. No total or dissolved lead was detected above cleanup levels in any well sampled. The report recommends ruling out lead as a COC. Comments recommended porewater sampling for DRO near UB-B16MW, as well as clarification for wells sampled. Tim Sharp
11/17/2020 Document, Report, or Work plan Review - other DEC approved the Final 2020 Groundwater Monitoring Report. All comments were incorporated and NPS has agreed with the recommendation of adding pore water sampling to next year's contract. Tim Sharp

3/25/2021 Offsite Soil or Groundwater Disposal Approved DEC approved the work plan for transportation and remediation of contaminated soil in the Bartlett Cove Depot Remediation Cell. Six cubic yards of contaminated soil will be transported to Bicknell Inc. in Juneau. A TTD was submitted alongside the work plan. Tim Sharp
4/6/2021 Document, Report, or Work plan Review - other DEC Approved the Final 2021 WP for Groundwater Sampling Tim Sharp
10/8/2021 Document, Report, or Work plan Review - other DEC reviewed and sent comments on the Draft Groundwater Sampling Report. The Report discusses installation of a replacement MW, sampling of all wells indicated in the work plan, and pore water sampling. Two wells, one at the FTF and one at the UB, showed a possible increasing trend in DRO through M-K trend analysis. Further long-term monitoring and surface water sampling was recommended. Due to the increasing trend, DEC recommends further characterization to delineate the source areas. Tim Sharp
11/18/2021 Site Characterization Report Approved DEC approved the 2021 Groundwater Monitoring report. DEC still recommends further soil borings and monitoring well installation at both FTF and UB sites to further characterize the plumes, and is willing to discuss remedial options. Currently, the NPS project manager position is filled in a temporary capacity, so discussions of funding and future scheduled work are difficult to finalize at this time. DEC requested to meet with the new project manager position, if it has been filled, prior to the scheduling of further work at the site to discuss options. Tim Sharp
