NESHAP Subpart W is a radon emission standard for operating uranium mill tailings. In accordance with the Clean Air Act Amendments of 1990, this proposed rule would require the use of generally available control technology (GACT) to limit radon emissions from tailings at all uranium recovery facilities. Specific control technologies would be required at conventional tailings impoundments, evaporation ponds and heap leach piles.
