Designation of Areas for Air Quality Planning Purposes; Wisconsin; Redesignation of Oshkosh, WI, to Attainment for Carbon Monoxide

Özet

The USEPA redesignates Oshkosh, Wisconsin from unclassifiable to attainment status for carbon monoxide. The State of Wisconsin requested this redesignation and provided the necessary monitoring data for USEPA to approve the change. The redesignation has no substantive effect because unclassifiable areas are subject to the same requirements as attainment areas. Elsewhere in this Federal Register, USEPA is proposing approval of and soliciting public comment on this redesignation. If adverse comments are received in the time period specified below, USEPA will withdraw this final rule and address the comments in a subsequent final rule.
