OSHA's Notice of Proposed Rulemaking (NPRM) for Occupational Exposure to Respirable Crystalline Silica has been submitted for publication in the Federal Register. The NPRM is OSHA's formal notice of regulatory action related to Occupational Exposure to Crystalline Silica. This is a proposal, not a final rule.
The proposed rulemaking would reduce the amount of silica exposure allowed in general industry and the maritime industry by 50 percent. The exposure limit in the construction industry would be cut by 80 percent.
