Activists Urge EPA To Use Modeling In Making SO2 NAAQS Designations

摘要

Environmentalists are urging EPA to rely largely on modeling rather than monitoring when designating areas in or out of attainment with the agency's sulfur dioxide (SO2) national ambient air quality standard (NAAQS), saying it can more accurately quantify emissions and would be far less expensive than launching a major new SO2 monitoring network.
