Secretary's Science Advisory Board on Toxic Air Pollutants
The Science Advisory Board (SAB) was convened to aid DENR in making assessments of potential health hazards resulting from exposures to toxic air pollutants. The Board is comprised of seven individuals with expertise in the fields of Exposure Assessment, Occupational Medicine, Toxicology, Risk Assessment, and Biostatistics. The SAB meets regularly to perform risk assessments on toxic air pollutants emitted in North Carolina. Their final recommendations are considered by DENR in drafting proposals for acceptable ambient air level (AAL) concentrations for toxic air pollutants in North Carolina.

Site Assessments
Other risk-based activities of the Toxics Protection Branch include providing input into the development of monitoring plans for site assessments. It is critically important to generate relevant exposure information in site investigations. Input from the risk group might include suggestions for monitoring placement and/or times, depending on the nature of the potential human exposures. Exposure assessment and characterization is a critical component of the risk assessment process and the ability to characterize real-life scenarios will aid in establishing project priorities. The Toxics Protection Branch is committed to maintaining comprehensive and effective efforts in this area.

Exposure Assessment Guidance for Site-Specific/Inhabitability Demonstrations
This document is intended to provide guidance for facilities subject to the North Carolina Air Toxics Program seeking to pursue a site-specific/inhabitability demonstration in accordance with 15A NCAC 2H.0610(c)(2)(A). The level of documentation needed for an inhabitability demonstration will vary, depending on the situation being considered. Potential exposures should be defined through consideration of activity patterns and ambient air impacts in the area of concern. As a rule of thumb, the burden of proof will be higher in those cases where cumulative exposures in "uninhabitable" areas may approach or exceed cumulative exposures expected at AAL concentrations. DAQ staff should be contacted for further guidance on this matter.
