Approval and Promulgation of Implementation Plans; Revision to the New York State Implementation Plan for Carbon Monoxide; Determination of Length of Control Period for New York-Northern New Jersey-Long Island Consolidated Metropolitan Statistical Area

The Environmental Protection Agency (EPA) is announcing the approval of portions of a request by the State of New York to revise its State Implementation Plan for Carbon Monoxide. EPA is approving New York's carbon monoxide plan which includes a vehicle miles travelled forecast, carbon monoxide emission inventory, multi-state coordination commitment, and Downtown Brooklyn Master Plan. EPA is also approving the State's use of the wintertime gasoline volatility program as a contingency measure. In addition, EPA is partially approving the State's oxygenated fuels rule. EPA will be taking action on New York's attainment demonstration, revised new source review program, conformity rules, and enhanced vehicle inspection and maintenance program in a separate Federal Register action. These revisions were required by the Clean Air Act as amended in 1990 and will contribute towards attaining the carbon monoxide standard. EPA is also determining that the period prone to high ambient concentrations of carbon monoxide in the New York-Northern New Jersey- Long Island Consolidated Metropolitan Statistical Area extends for the four month period from November 1 through the last day of February. This is the control period for carbon monoxide when State programs in this area must require oxygenated gasoline.
