Approval and Promulgation of Implementation Plans; Indiana

摘要

On November 24, 1993, the United States Environmental Protection Agency (USEPA) proposed to approve a State Implementation Plan (SIP) request for Vermillion County, Indiana. The request was submitted by the State of Indiana for the purpose of attaining the National Ambient Air Quality Standards (NAAQS) for particulate matter with an aerodynamic diameter less than or equal to a nominal 10 micrometers (PM), and to satisfy Clean Air Act (Act) requirements for an approvable nonattainment area PM SIP for Vermillion County, Indiana. Public comments were solicited on the proposed SIP revision, and on USEPA's proposed rulemaking action. No public comments were received. This rulemaking action approves in final the Vermillion County, Indiana SIP revision as requested by Indiana.
