## Abstract

The Environmental Protection Agency (EPA) approves new sections to the Idaho State Implementation Plan (SIP) that contain the State's transportation conformity rule and an interim transportation conformity rule for the Northern Ada County former nonattainment area for particulate matter under ten microns (PM-10). These new sections to Rules for the Control of Air Pollution in Idaho (IDAPA) include IDAPA sections 58.01.01.563 through IDAPA 58.01.01.574, and IDAPA 58.01.01.582. These sections were submitted as part of a series of revisions to the SIP to EPA on December 6, 2000 and February 9, 2001.
