Abstract
EPA is partially approving and partially disapproving a State Implementation Plan (SIP) revision submitted by the State of Colorado regarding its Regulation 1. Regulation 1 provides certain emission controls for opacity, particulates, carbon monoxide and sulfur dioxide. The revision involves the deletion of obsolete, the adoption of new, and the clarification of ambiguous provisions within Regulation 1. The intended effect of EPA's action is to make Federally enforceable the revised portions of Colorado's Regulation 1 that EPA is approving and to disapprove portions of the regulation that EPA deems are not consistent with the Clean Air Act. This action is being taken under section 110 of the Clean Air Act.
