Laws and Rules
The federal Clean Air Act (CAA) outlines the requirements for state implementation plans (SIPs):
- States must have SIPs
- U.S. EPA must approve these SIPs
- SIPs must contain specific elements, as required by the CAA
State law at Title 13, Article 17 of the Indiana Code (IC 13-17) establishes the authority to adopt laws and rules that are necessary for the implementation of the CAA in Indiana. State law at IC 13-13-5 designates the Indiana Department of Environmental Management (IDEM) as Indiana's air pollution control agency for all purposes of the federal CAA.
State rule at Title 326, Chapter 1, Article 2, Section 78 of the Indiana Administrative Code (326 IAC 1-2-78 [PDF]) defines Indiana’s SIP.
The Code of Federal Regulations (CFR) contains Indiana's SIP at 40 CFR 52 Subpart P [PDF]. U.S. EPA provides Approved Regulations and Statutes in the Indiana SIP online.
