## Abstract

Environmental Protection Agency (EPA) approves Oregon's Transportation conformity rules received on April 17, 1995, from the Oregon Department of Environmental Quality (ODEQ). The Clean Air Act (CAA or Act) requires the states to promulgate conformity rules to ensure that Federal actions conform to the appropriate State Implementation Plan (SIP). Conformity to a SIP is defined in the CAA, as amended in 1990, as meaning conformity to a SIP's purpose of eliminating or reducing the severity and number of violations of the national ambient air quality standards (NAAQS) and achieving expeditious attainment of such standards. The Federal agency responsible for the action is required to determine if its actions conform to the applicable SIP.
