Pebble Mine is the common name of a proposed copper-gold-molybdenum mining project in the Bristol Bay region of Southwest Alaska, near Lake Iliamna and Lake Clark. As of November 2020 the mine developer, Northern Dynasty Minerals, was seeking federal permits from the United States Coast Guard and the Bureau of Safety and Environmental Enforcement. State permitting would then follow, which the developer expected to take up to three years. In November 2020, the developer was denied a U.S. Army Corps of Engineers (USACE) permit for its proposed mine discharge plan. On September 9, 2021, it was reported that the EPA had "asked a federal court to allow for Clean Water Act protections for parts of the bay."
