Air Plan Approval; Wisconsin; Particulate Matter Standard

The Environmental Protection Agency (EPA) is approving a January 4, 2018, request by the Wisconsin Department of Natural Resources (Wisconsin) to revise its state implementation plan (SIP) for fine particulate matter (PM 2.5 ). Wisconsin updated its ambient air quality standards for PM 2.5 to be consistent with EPA's 2012 revision to the PM 2.5 national ambient air quality standards (NAAQS). Wisconsin also revised its incorporation by reference rule to update references to the EPA monitoring methods.
