Third proposal for wool insulation manufacturers

摘要

The EPA has issued its third proposal in 3 years to amend the Agency's original 1999 National Emissions Standards for Hazardous Air Pollutants (NESHAP) for the mineral wool production and wool fiberglass manufacturing sectors. The current proposal addresses comments made on the previous proposals, explains changes to previously proposed limits for sources in these industries, and clarifies EPA's use of the upper prediction limit (UPL) in setting maximum achievable control technology (MACT) floors.
