The evaluation of the Alaska Department of Environmental Conservation (ADEC) Air Compliance and Enforcement Program was based on information from: ADECs policies, procedures, and protocols; interviews; source file reviews; the states database; EPAs national database (AFS); ADECs Compliance Monitoring Strategy (CMS) Plan; ADECs annual work plan; the EPA/ADEC Compliance Assurance Agreement; and EPAs national stationary air source policies. EPA Region 10 selected 15 sources for file reviews, divided into three groups: 5 major sources on the High Priority Violation (HPV) list; 5 non-HPV major sources; and 5 synthetic minor sources (4 of which are SM-80s and 1 is an HPV). Sources were randomly selected within each of the three groups, but were chosen to represent a variety of types and locations of the sources. The time period evaluated was federal fiscal year 2003, but because some of the enforcement actions that were taken in 2003 addressed violations that occurred in earlier years, we reviewed files with information back to 2000, 2001, or 2002, as appropriate. Appendix A lists the sources that were selected for the file reviews.
