The Secretary's Science Advisory Board on Toxic Air Pollutants (NCSAB)
The Secretary's Science Advisory Board on Toxic Air Pollutants (NCSAB) is chartered by the Secretary of the Department of Environment and Natural Resources (DENR). The Board's primary responsibility is to assess the potential human health effects associated with North Carolina toxic air pollutants and recommend a range of acceptable ambient levels (AALs) likely to safeguard against adverse health effects.
The NCSAB is composed of eight members, appointed to four-year terms, having expertise in the following disciplines:
Air pollutants evaluated by the NCSAB are identified through several mechanisms including:
The NCSAB may also conduct site-specific risk assessments, assess health risks due to exposure to chemical mixtures, and consider multi-media effects on exposure or other specific topics of importance to DENR. The NCSAB uses scientific risk assessment methods and standard practices in deriving AALs for toxic air pollutants emitted in North Carolina. The Board utilizes current, relevant, peer-reviewed toxicological literature and presentations prepared by expert scientists as the basis for all assessments.
The Division of Air Quality (DAQ) manages and coordinates the chemical evaluations and risk assessments conducted by the NCSAB. A list of chemicals to be evaluated is generated and prioritized by DAQ on a yearly basis through a combined assessment of emission levels, toxicological properties, and potential human exposures.
The NCSAB generally meets bimonthly. NCSAB meetings are open to the public and participation by interested groups is encouraged. Logistical support for NCSAB meetings is provided by DAQ.
