Approval and Promulgation of Implementation Plans; Carbon Monoxide Maintenance Plan, Conformity Budgets, Emissions Inventories; State of New York

The Environmental Protection Agency (EPA) is approving a State Implementation Plan (SIP) revision submitted by the New York State Department of Environmental Conservation. This revision establishes an updated ten-year carbon monoxide (CO) maintenance plan for the New York portion of the New York-Northern New Jersey-Long Island (NYCMA) CO area which includes the following seven counties: Bronx, Kings, Nassau, New York, Queens, Richmond and Westchester. In addition, EPA is approving a revision to the CO motor vehicle emissions budgets for New York and revisions to the 2007 Attainment/Base Year emissions inventory. The New York portion of the NYCMA CO area was redesignated to attainment of the CO National Ambient Air Quality Standard (NAAQS) on April 19, 2002 and maintenance plans were also approved at that time. By this action, EPA is approving the second maintenance plan for this area because it provides for continued attainment for an additional ten years of the CO NAAQS. The intended effect of this rulemaking is to approve a SIP revision that will insure continued maintenance of the CO NAAQS.
