Problems/Comments
The Point Whitshed Naval Station is located 8 miles southwest of Cordova. The Native Village of Eyak conducted a Preliminary Site Assessment of this site as part of the 2007 – 2008 Cooperative Agreement under the Native American Lands Environmental Mitigation Program (NALEMP). This is the first PA conducted since its deactivation by the Navy in 1917. A 200 foot steel tower and a large, water-filled cistern are the most prominent features. Both represent safety hazards to individuals, including children either from falling or drowning. They will be mitigated as part of the on-going CA. The soils and ground around the 6,500-gallon tank farm may be contaminated with petroleum products. There may also be the presence of drum or hazardous waste dumps yet to be discovered. Diesel Range Organics were found in soil up to 9230 mg/kg, lead 2060 mg/kg and Residual Range Organics at 10100 mg/kg at the fuel tank farm.

| 7/19/2012 | Document, Report, or Work plan Review - other | Feasibility Study for Point Whitshed and Mile 14 Sites, Cordova, July 2012. The final Feasibility Study (FS) prepared for the Native Village of Eyak under the Native American Lands Environmental Mitigation Program. This report also contains the laboratory data and data quality assurance for the previous characterization samples obtained at the Point Whitshed and Mile 14 Sites. The contaminants of concern at both sites are lead and diesel range organics. The report suggests additional soil sampling to complete the delineation of the volume of soil that will need remediation and the installation of monitoring wells to determine if there is impact to the groundwater. If this is pursued, please submit a work plan to ADEC for the proposed work (18 AAC 75.335). I would also suggest that groundwater samples at Point Whitshed be analyzed for salinity to determine if the water could be used as a drinking water source. | Debra Caillouet |

| 12/28/2015 | Site Characterization Report Approved | DEC Approved the 2015 Site Characterization Report, Point Whitshed Naval Transmitter Station, Cordova Vicinity, Alaska. The data compiled in this report consisted of three phases- seven sampling events from 2008-2010, soil and surface water sampling in July 2013, and shallow groundwater sampling in 2015. Analytical data from the investigation indicated that approximately 750 bank cubic yards of soil is contaminated by diesel-range organics (DRO) and lead at concentrations that exceed DEC human health cleanup levels. The actual volume may be greater if contamination extends deeper than 2 feet. The report suggests that excavation and offsite disposal appears to be the viable and recommended remedial alternative for the lead-contaminated soil. Analytical data from a single sampling event indicate that the shallow groundwater at the site is not impacted by petroleum hydrocarbon at concentrations exceeding applicable cleanup levels. However, given that soil contains residual concentrations that exceed the applicable cleanup levels, per 18 AAC 75.345(h), the department will require long-term monitoring to definitively conclude that groundwater has not been impacted and will not be impacted in the future. | Monte Garroutte |
| 8/2/2018 | Document, Report, or Work plan Review - other | DEC approved the Soil Remediation at the Mile 14 & Point Whitshed Naval Radio Station Sites Work Plan, dated July 2018. The Work Plan describes proposed activities to delineate the extent of contaminated soil at the Mile 14 Naval Radio Station Site and remove soil from both the Mile 14 and Point Whitshed Naval Radio Station sites. The work is expected to begin in 2018, and continue into 2019. Contaminants of concern (COCs) at both sites are diesel range organics (DRO) and lead. On July 27, 2018, DEC provided a conditional approval so the contractor could begin the fieldwork scheduled to begin during the week of July 30, 2018. | Erica Blake |
| 6/17/2019 | Update or Other Action | Site location was updated on this date. Coordinates for this site are used to determine the presence and position of the site on BLM’s ANCSA Conveyed Land web map. | Rebekah Reams |
| 1/17/2024 | Site Characterization Report Approved | DEC reviewed and approved the Lead-and Petroleum Contaminated Soil Removal Action Completion Report for the Mile 14 Naval Radio Station Site 3. This report was drafted and submitted on behalf of the Native Village of Eyak. This report documented the removal of lead and petroleum contaminated soils during the 2023 field season at the location of the former Powerhouse area. Approximately 266 cubic yards of contaminated soils were excavated and removed. Additional site characterization and remedial action are needed at this site. Additional investigation and soil removal is planned for the 2024 field season. | Kelly Walker |
