Approval and Promulgation of Air Quality Implementation Plans; Colorado; Regulation 7

EPA is approving revisions to the Colorado Ozone State Implementation Plan (SIP) submitted by the Governor on September 27, 1989, and August 30, 1990. The revisions consisted of amendments to Regulation No. 7, ``Regulation To Control Emissions of Volatile Organic Compounds.'' In its review of the September 27, 1989 State submittal, EPA identified several areas where the regulation still did not meet EPA requirements. On August 30, 1990, the State submitted additional revisions to Regulation No. 7 to address these deficiencies. This Federal Register action applies to both of these submittals. The amendments were made to conform Regulation No. 7 to federal requirements, and to improve the clarity and enforceability of the regulation. EPA's approval will serve to make the revisions federally enforceable and was requested by the State of Colorado.
