Narrative Summary of New Rule or Rule Changes: New Rule Amended Rule 

The adopted amendments will implement RACT for the Miscellaneous Metal Parts and Products Coating source 

category, as required by Section 182(b)(2)(A) of the federal Clean Air Act. The rule amendments make the rule at 

least as stringent as the applicable metal coating requirements of the Control Techniques Guidelines for 

Miscellaneous Metal and Plastic Parts Coatings (EPA-453/R-08-003). The adopted amendments lowered the 

VOC limits for three coating categories: aluminum coatings for window frames and door frames, extreme 

performance coatings, and non-skid coatings. The adopted amendments also added a new coating category for 

etching filler and added an exemption for automobile and light-duty truck assembly coating operations. 

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2

VI. IMPACT ON AIR QUALITY PLAN 

 No Impact Impacts RFP Impacts attainment 

Discussion: No sources subject to Rule 451 in Sacramento County will be required to change their operations as a result 

of the amendments to Rule 451. Therefore, there are no impacts on the air quality plan.
