Air Quality
Rules & Planning

What is a State Implementation Plan?
The State Implementation Plan (SIP) lays out goals and procedures to protect the state's air quality. The federal Clean Air Act (CAA), which became law in 1971 and was amended in 1990, provides the national framework for efforts to protect air quality. The US EPA has delegated most of the available programs for implementing and enforcing the act to the Air Quality Division of DEQ.  Regulation at the state level means that local needs and conditions are better understood, responded to, and managed.

Oklahoma's EPA-approved SIP lays out the goals and procedures for the daily operations of AQD.  It includes the Oklahoma Air Quality Rules and other strategies developed at the state level for implementing the various federal air quality programs. The core focus of the air quality program is to implement, maintain, and enforce the National Ambient Air Quality Standards (NAAQS). The SIP is regularly reviewed and amended as necessary. In addition, EPA requires the state to demonstrate that the SIP meets the "infrastructure" requirements of CAA Section 110(a)(2) (A)-(M) each time a NAAQS is issued or revised. These "infrastructure SIPs", or I-SIPs, are posted for public comment on this page when proposed, and are then archived on the I-SIP page once they are finalized and submitted to EPA.

How are Oklahoma's Air Quality Rules Made?
The AQD Rules and Planning Section proposes rule updates to the Air Quality Advisory Council, which consists of nine members appointed by the Governor to represent various Oklahoma stakeholders.  After proposed rule changes have been open for public review and comment, public hearings are held.  If a rule change is approved by the Council, it is recommended to the Oklahoma Environmental Quality Board. Once adopted by the Board, the new rules proceed to the State Legislature and the Governor for final approval.
