Redesignation and Approval and Promulgation of Indiana Implementation Plans

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to redesignate Lake County, Indiana, to attainment for particulate matter with a nominal aerodynamic diameter of 10 microns or less (PM

10

). EPA also proposes to approve Indiana's plan for continuing to attain the PM

10

standards.

DATES:

Written comments on this proposed rule must arrive on or before February 10, 2003.

ADDRESSES:

You should mail written comments to: J. Elmer Bortzer, Chief, Regulation Development Section, Air Programs Branch (AR-18J), U.S. Environmental Protection Agency, Region 5, 77 West Jackson Boulevard, Chicago, Illinois 60604.

SUPPLEMENTARY INFORMATION:

On September 25, 2002, Indiana requested that EPA redesignate Lake County from nonattainment to attainment for PM

10

. The criteria for redesignations from nonattainment to attainment are in section 107(d)(3)(E) of the Clean Air Act. EPA proposes to conclude that (i) Lake County has attained the PM

10

air quality standards, (ii) EPA has fully approved the applicable State Implementation Plan (SIP) under section 110(k) of the Act, (iii) the improvement in air quality in the area is due to permanent and enforceable emission reductions, (iv) the maintenance plan for the area satisfies section 175A of the Act, and (v) the state has met all requirements applicable to the area under section 110 and part D of the Act. Based on these findings, EPA proposes to approve Indiana's maintenance plan and redesignate Lake County, Indiana, to attainment for PM

10

.
