How are toxic air pollutants regulated in North Carolina?
In addition to being the implementing authority for the federally established MACT standards, North Carolina also has a health-based toxic air pollutant control program, in effect since May 1, 1990, that regulates 105 toxic air pollutants (TAPs). Most of the TAPs are also considered HAPs by the EPA. To date the focus of the program has been on stationary sources of emissions and human health effects of air toxics. In North Carolina’s program, once evaluated a facility must limit its emissions so that the resulting modeled ambient levels of TAPs at the property boundary remain below health-based acceptable ambient levels (AALs). The AALs are recommended by a Scientific Advisory Board (SAB) and are established in the state Rules by the North Carolina Environmental Commission. The Rules containing the TAP AALs and associated compliance demonstration and permitting procedures are found in 15A NCAC 2D.1100, Control of Toxic Air Pollutants and 15A NCAC 2Q.0700, Toxic Air Pollutant Procedures
