Transportation Conformity Rulemaking


ADEQ is considering amending or repealing the rules in Arizona Administrative Code Title 18, Chapter 2, Article 14 because they are inconsistent with federal transportation conformity laws. In 2008, the U.S. Environmental Protection Agency (EPA) streamlined transportation conformity state implementation plan (SIP) requirements to only address the following sections of federal rules in the code of federal regulations (CFR): 40 C.F.R. §§ 93.105, 93.122(a)(4)(ii), 93.125(c). ADEQ will submit any rule changes to EPA for approval in Arizona’s SIP.
