2. Rule Set Information  
MOAHR assigned rule set number:  
2023-13 EQ  
Title of proposed rule set:  
Part 8. Emission Limitations and Prohibitions-Oxides of Nitrogen  
3. Purpose for the proposed rules and background:  
Part 8. Emission Limitations and Prohibitions – Oxides of Nitrogen of the Michigan Air Pollution  
Control Rules (MAPCR) contains rules developed to fulfill federal Clean Air Act, 42 U.S.C. 7401 et  
seq (CAA) requirements for sources of oxides of nitrogen (NOx). Michigan must create new rules to  
address a change to a moderate classification in nonattainment areas under provisions of the National  
Ambient Air Quality Standards (NAAQS). These rules are often referred to as NOx “Reasonably  
Available Control Technologies” (RACT). For past NAAQS, the Department of Environment, Great  
Lakes, and Energy (EGLE) was not required to promulgate RACT rules for NOx sources in the  
nonattainment areas established under those standards. With the establishment of a new standard and  
a new classification, Michigan must create RACT rules to align with requirements of Section 182(b)  
(2) of the CAA. EGLE must promulgate new rules setting emission standards and operational  
requirements for certain types of NOx emission sources for the nonattainment areas.  
Additionally, existing Part 8 Rules addressing the “NOx State Implementation Plan (SIP) Call”  
federal program will be modified to address minor improvements suggested by representatives of the  
United States Environmental Protection Agency (EPA).  
4. Summary of proposed rules:
