Abstract

The Environmental Protection Agency (EPA) is approving a state implementation plan (SIP) revision submitted by the State of Maryland. This revision (Maryland Submittal #24-01) pertains to the re-allocation of nitrogen oxides (NO<INF>X</INF>) ozone season emission caps for large non-electric generating units (non-EGUs, affected units). The amendment also updates a cross reference to the Cross State Air Pollution Rule (CSAPR). This action is being taken under the Clean Air Act (CAA).
