Opened in 1999, the U.S. Department of Energy's Waste Isolation Pilot Plant near Carlsbad, New Mexico is the first "deep geologic repository" in the world for radioactive wastes, specifically for disposing of plutonium-contaminated nuclear weapons complex wastes. As described on WIPP's homepage, the "Waste Isolation Pilot Plant uses a continuous miner to carve disposal rooms out of the Permian Salt Formation, nearly a half mile below the surface," as pictured at the left. Despite assurances by WIPP's "Chief Scientist" that it could never happen, carbon tetrachloride leaks to the air outside the facility located 2,150 feet below ground have now reached a "level of concern," as reported by a Concerned Citizens for Nuclear Safety (CCNS) news update based on research by the Southwest Research and Information Center (SRIC). Beyond Nuclear, CCNS, and SRIC are members of the Alliance for Nuclear Accountability. ANA's annual DC Days will be held in Washington March 14-17.
