Progress Report

Affected Units

Under the Acid Rain Program (ARP) and Clean Air Interstate Rule (CAIR) sulfur dioxide (SO₂) and nitrogen oxides (NOₓ) annual programs, emission reductions generally apply to large electricity generating units (EGUs)—boilers, turbines, and combined cycle units—that burn fossil fuels to generate electricity for sale. The CAIR NOₓ ozone season program included EGUs and, in some states, large industrial units that burn fossil fuels and have been carried over from the NOₓ Budget Trading Program (NBP). This section covers units affected in 2014, and does not include programs not being implemented in 2014 (NBP and Cross-State Air Pollution Rule [CSAPR]).
