Abstract
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<INF>2.5</INF>). Wisconsin updated its ambient air quality standards for PM<INF>2.5</INF> to be consistent with EPA's 2012 revision to the PM<INF>2.5</INF> national ambient air quality standards (NAAQS). Wisconsin also revised its incorporation by reference rule to update references to the EPA monitoring methods.
