## Abstract

EPA is taking final action to correct the May 2004 approval of a version of the New Source Review (NSR) rules for the San Joaquin Valley Unified Air Pollution Control District portion of the California State Implementation Plan, consistent with the relevant provisions of state law. Specifically, EPA is taking final action to correct the May 2004 approval by limiting the approval, as it relates to agricultural sources, to apply the permitting requirements only to such sources with potential emissions at or above a major source applicability threshold and to such sources with actual emissions at or above 50 percent of a major source applicability threshold and to apply the emission offset requirement only to major agricultural sources and major modifications of such sources.
