Designation of Areas for Air Quality Planning Purposes; Indiana

On March 3, 1978, the EPA published a final rule designating part of Porter County, Indiana as nonattainment for sulfur dioxide (SO<INF>2) and the remainder of Porter County as ``better than national standards'' (43 FR 8962). On October 5, 1978, the EPA designated the formerly nonattainment portion of Porter County (the area bound on the north by Lake Michigan, on the west by the Lake-Porter County line, on the south by I-80 and 90 and on the east by the LaPorte-Porter County line) as ``cannot be classified'' for SO<INF>2 (43 FR4993). Inadvertently, however, the revised Porter County status designation was not correctly printed in subsequent Codes of Federal Regulations (40 CFR 81.315). It is being corrected in this rule.
