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.

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 .
