Glass_Heifner Mine Administrative Record


he National Park Service (NPS) wishes to inform and encourage the public to review action and information documents for the Glass-Heifner Mine Site in Kenai Fjords National Park, Kenai Peninsula Borough, Alaska. Documents are in the Administrative Record File at the repositories listed below. Although public comments are welcome at any time, a formal public comment period will occur March 25 - April 30, 2024.

The Glass-Heifner Mine Site is located in the Nuka Bay Historic Mining District within Kenai Fjords National Park (KEFJ), approximately 60 miles southwest of the town of Seward. The site is a former gold mine that was intermittently active starting in the mid-1920s, with periods of commercial mining between 1965 and the mid-1970s.

In 1994, NPS began environmental investigations to evaluate potential risks posed to human health and the environment by contaminants at the Site. From 1994-1995 NPS sampled soil and water from areas around the Site and determined that arsenic was found in the tailings at levels that exceeded cleanup levels. In 1998, NPS consolidated material from the tailings into a cement-capped impoundment on site. In 2021, NPS discovered that recent erosion at the site was threatening the integrity of the impoundment and initiated a CERCLA Time-Critical Removal Action. Next steps include resuming cleanup work next summer when conditions allow access. After Summer 2024, future steps may include additional environmental investigations. For more information on this process read Community Update.
