摘要

State environmental agencies are split over how best to demonstrate that control of precursor emissions is not necessary for an area to attain the current national ambient air quality standards for fine particulate matter, comments submitted to the Environmental Protection Agency show. While several state and local agencies recommended that the EPA codify all three proposed precursor demonstration methods in order to provide states with maximum flexibility, other state agencies expressed a preference for the EPA to establish a single test for assessing the regulation of sulfur dioxide, nitrogen oxides, volatile organic compounds and ammonia under the fine particulate standards.
