Approval and Limited Approval and Limited Disapproval of California State Implementation Plan Revisions; Butte County Air Quality Management District; Stationary Source Permits

The Environmental Protection Agency (EPA) is finalizing action on three permitting rules submitted as a revision to the Butte County Air Quality Management District (BCAQMD) portion of the California State Implementation Plan (SIP). We are finalizing a limited approval and limited disapproval of one rule; we are finalizing approval of two permitting rules; and we are deleting ten rules from the SIP. These revisions concern the District's New Source Review (NSR) permitting program for new and modified sources of air pollution. This limited disapproval will trigger sanctions under CAA section 179 and 40 CFR 52.31 unless the EPA approves subsequent SIP revisions that correct the rule deficiencies within 18 months of the effective date of the final action.
