Approval and Promulgation of Implementation Plan; Michigan
Traducción automática local · Idioma original de la fuente
Resumen
The United States Environmental Protection Agency is approving Michigan's 1990 base year ozone (O 3) emission inventory for the Grand Rapids and Muskegon nonattainment areas (NAAs) submitted as a revision to the Michigan State Implementation Plan (SIP) for O 3. Michigan's O 3 NAAs are the counties of Muskegon, and the two county Grand Rapids area (which are the counties of Kent and Ottawa). The inventory was submitted by the State of Michigan to satisfy a requirement that those States containing O 3 nonattainment areas (NAAs) classified as marginal to extreme to submit inventories of actual O 3 season and emissions from all sources in accordance with USEPA guidance. The rationale for the approval is set forth in this final rule; additional information is available at the address indicated below in the supporting Technical Support Document (TSD).
