The Environmental Protection Agencys (EPAs) Office of Enforcement and Compliance Assurance (OECA), all ten EPA Regions, the Environmental Council of States (ECOS) Compliance Committee and other state representatives have jointly developed a method to assess state performance in the enforcement and compliance assurance program. This report reflects the FY2004 review by Region 4 of the North Carolina Department of Environment and Natural Resources (NCDENR) compliance and enforcement program and the Forsyth County Environmental Affairs Department (Forsyth County) Air compliance and enforcement program utilizing the State Review Framework (SRF). This review has been a collaborative effort between the Region, State and Forsyth County and captures both successes of the State and Forsyth County programs as well as any identified areas that need improvement. As this is the first review of this type for NCDENR and Forsyth County, this report will serve as a baseline review. Future reviews will look at performance as a comparison to the level documented in this review. The purpose of the SRF assessment is to provide consistency in the level of core enforcement activity and performance thus in environmental protection across the country. It provides a consistent tool for EPA Regions to use in overseeing state enforcement program performance as well as to provide the basis for a consistent mechanism for EPA Regions to provide flexibility to states which can demonstrate an adequate core enforcement program.
