Problems/Comments
The Bartlett Cove Firing Range is located at the National Park Service Depot site, about 1 mile from the dock facilities at Bartlett Cove. It has been used for firearms training and certification since 1996, and will continue to be used as a firing range for the foreseeable future. In 2009 the Park converted to green ammunition for training, but still uses service ammunition for certifications. The firing range consists of a soil berm that is approximately 8 feet high by 50 feet wide. Firing is completed at distances of 9, 21, 45, 75, and 150 feet from the face of the target near the berm. In 2012 the NPS contractor performed a lead asessment at the site. Sample results indicate that areas with elevated lead, arsenic, antimony, and copper are present. Contaminated soil was removed in 2014. Confirmation sample results are below cleanup levels for antimony, copper, and lead. Arsenic results are above the cleanup level, but within background concentrations.
Action Information
| Action Date | Action | Description | DEC Staff |
|---|---|---|---|
| 5/18/2012 | Site Added to Database | A new site has been added to the database | Mitzi Read |
| 5/30/2012 | Site Characterization Workplan Approved | Approved the final work plan for the Firing Range lead assessment. The firing range floor and berm will be divided into grids, and a five-point composite sample will be collected from each square. Samples will be analyzed for lead, with a limited number of samples also analyzed for arsenic, antimony, barium, copper, nickel, and zinc. | Melody Debenham |
| 3/15/2013 | Site Characterization Report Approved | Approved the final lead assessment report. The firing range consists of a soil berm approximately 12 feet high by 50 feet wide. Firing is completed at distances of 9, 21, 45, 75, and 150 feet from the face of the target near the berm. The range has been used for firearms training and certification since 1996, and will continue to be used as a firing range for the foreseeable future.

| 8/14/2014 | Document, Report, or Work plan Review - other | Approved final cleanup and site assessment work plan describing the removal of lead impacted soil identified in 2012. Additional work includes sampling to determine the background concentrations of arsenic at the site and collecting a groundwater from the existing montitoring well for metals analysis. | Melody Debenham |
| 9/30/2014 | Potentially Responsible Party/State Interest Letter | Potentially responsible party letter sent to the National Park Service. | Melody Debenham |
| 12/17/2014 | Document, Report, or Work plan Review - other | Approved final Glacier Bay Firing Range Lead Cleanup and Additional Site Assessment 2014 report documenting the removal and proper disposal of 32 cubic yards of lead, antimony, copper, and arsenic contaminated soil. Confirmation samples show the only contaminant remaining above cleanup levels is arsenic, however arsenic concentrations are within the sampled background concentrations at the site. One groundwater sample was collected and analyzed for metals. No metals were detected in the groundwater. | Melody Debenham |
| 4/18/2016 | Exposure Tracking Model Ranking | A new updated ranking with ETM has been completed for source area 79430 Depot Firing Range. | Melody Debenham |
| 5/4/2016 | Cleanup Complete Determination Issued | Cleanup Complete determination issued. No further remedial action is required, subject to the following Standard Conditions: 1. Any proposal to transport soil or groundwater off-site requires ADEC approval in accordance with 18 AAC 75.325.
