Comments on EPA's Reconsideration of the National Ambient Air Quality Standards (NAAQS) for Particulate Matter
The National Stone, Sand & Gravel Association (NSSGA) appreciates the opportunity to comment on the U.S. Environmental Protection Agency (EPA) reconsideration proposal for the National Ambient Air Quality Standards (NAAQS) for Particulate Matter (PM). NSSGA is a member of both the Coarse Particulate Matter Coalition (CMPC) and the NAAQS Regulatory Review & Rulemaking (NR3) Coalition, and incorporates their comments by reference. NSSGA supports the proposal for retention of the current standard for PM10, but opposes the reduction of the PM2.5 standard.
