Rule No(s): 3.21 Date adopted/Amended/Rescinded: Adopted June 5, 2006 

Rule Title(s): Industrial, Institutional, and Commercial Boilers, Steam Generators, and Process Heaters 

Date Submitted to ARB: April 18, 2013 

If an Amended Rule, Date Last Amended (or Adopted): N/A 

Is the Rule Intended to be Sent to the U.S. EPA as a SIP Revision? Yes No (If No, do not complete remainder of form)

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

Rule 3.21 requires various boilers, steam generators, and process heaters that have a rating greater than 1 

million BTU per hour to employ a compliance strategy. Small boilers, those rated between 1 to 5 MMBTU/hr, will 

generally either limit their permitted operations to less than 90,000 therms per year or be tuned-up once a year by 

a qualified technician. Larger boilers, those rated above 5 MMBTU/hr, will generally have to be source tested 

using EPA/CARB approved test methods to show compliance with the Rule emission limits. 

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

 (CO) PM TAC (name): 

II. EFFECT ON EMISSIONS 

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission factor(s) 

and other information. Attach calculation sheet showing how the emission information provided below was determined. 

Net Effect on Emissions: Increase Decrease N/A 

Emission Reduction Commitment in SIP for this Source Category: none 

Inventory Year Used to Calculate Changes in Emissions: 2008 Area Affected: Yuba and Sutter Counties 

Future Year Control Profile Estimate (Provide information on as many years as possible): 

The District identified 9 boilers with a capacity of 5 MMBTU/hr and 57 boilers with a capacity between 1-5 MMBTU/hr. 

NOx emission reductions from the larger boilers are estimated to be around 5.47 tons/yr in North FRAQMD and 0 tons/yr 

in the SFNA portion of the District. The smaller boilers will be tuned-up once a year, which will demonstrate that the CO 

emissions won't rise above 400 ppm.
