Amends GS 143-215.107(a)(5) (concerning air quality standards) to require the Department of Environment and Natural Resources (DENR) to review permit applications for new or modified sources or facilities that would increase emission of toxic air pollutants; if DENR finds, through modeling, epidemiological studies, monitoring data, or other information, that the emission would pose an unacceptable risk to human health, the operator must submit a permit application that eliminates the risk. Exempts from rules controlling emission of toxic air pollutants any source that is subject to specified federal rules. Makes conforming changes.
Directs the Environmental Management Commission and the Division of Air Quality (Division) of DENR to review and amend their adopted rules, as detailed. Sets out Division reporting requirements.
