Approval and Promulgation of Implementation Plans; Indiana

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA proposes to approve revisions to Particulate Matter (PM) control requirements for certain natural gas combustion sources in Indiana. EPA also proposes to approve various cleanup revisions to Indiana's PM rules and contingency measures for the Lake County, Indiana PM nonattainment area. The Indiana Department of Environmental Management (IDEM) submitted these revisions to Title 326 of the Indiana Administrative Code, Section 6-1 (326 IAC 6-1) as a requested revision to the Indiana State Implementation Plan (SIP) on December 19, 2001. The requested SIP revision eliminates PM emissions limits on certain natural gas combustion sources in specified counties, and replaces the limits with a requirement that such sources may only burn natural gas. The requested SIP revision also contains many cleanup provisions such as eliminating limits for sources which have shut down and updating names of sources. Third, the requested SIP revision adds PM contingency measures for the Lake County, Indiana PM nonattainment area.

DATES:

EPA must receive written comments on this proposed rule by November 12, 2002.
