On February 21, 2020 at 85 FR 10064 the EPA approved a request from the Indiana Department of Environmental Management (IDEM) to revise the Indiana State Implementation Plan (SIP) to incorporate the following: A new rule concerning nitrogen oxide (NOX) emissions for the ozone season from Electric Generating Units (EGUs) and large non-EGUs; revisions concerning NOX emission rate limits for specific source categories; the repeal of the NOX Budget Trading Program; and the repeal of the Clean Air Interstate Rule (CAIR) NOX ozone season trading program. The State of Indiana submitted this revision as a modification to the SIP on August 27, 2018. In the direct final rule, EPA stated that if adverse comments were submitted by March 23, 2020, the rule would be withdrawn and not take effect. On March 23, 2020, EPA received adverse comments, and, therefore, is withdrawing the direct final rule. EPA will address the comments in a subsequent final action based upon the proposed action also published on February 21, 2020 (85 FR 10127). EPA will not institute a second comment period on this action.
