Supplemental Attach 3-ADEC Site Report Eldred Rock 1508.38.008 - 2699.pdf

This is a site report for the USCG Eldred Rock Light Station located in Lynn Canal, 20 Miles SSE of Haines, Alaska. The site, which began operation in 1906 and has been automated since 1973, has a history of environmental contamination. Investigations in 1997 and subsequent years revealed contamination from diesel fuel, with soil samples showing high concentrations of lead (up to 1,600 mg/kg), diesel-range organics (DRO), and other hazardous substances near the paint shop and former fuel storage areas.

Key actions include the USCG removing approximately 1,000 pounds of miscellaneous waste and debris in 2004, multiple site investigations, and ongoing discussions between the U.S. Coast Guard, the Eldred Rock Lighthouse Preservation Association (ERLPA), and the Alaska Department of Environmental Conservation (DEC). Recent activities focus on lease negotiations for the lighthouse property, site contamination assessments, and planned future teleconferences in 2024 and 2025 to discuss the Memorandum of Agreement (MOA) renewal for active USCG contaminated sites.
