Be sure to read Part I of this series to learn about emissions requirements in the SCAQMD.
In the last edition of Boiler Blog 101, we discussed air permitting rules and regulations in the South Coast Air Quality Management District (SCAQMD). In part II, we will cover the basics of air permitting for boilers in another California district that leads the country in air pollution control; the San Joaquin Valley Air Pollution Control District (SJVAPCD).
The SJVAPCD was founded in 1991 with a mission to improve the health and quality of life for all Valley residents through efficient, effective and entrepreneurial air quality management strategies. The SJVAPCD is made up of eight counties in the Central Valley of California; San Joaquin, Stanislaus, Merced, Madera, Fresno, Kings, Tulare, and Kern.
The rules that have been set forth specifically for boilers, steam generators, and process heaters are outlined below:
| QUALIFYING UNITS | NOx LIMIT | |
| Rule 4306 | Units Greater Than 5 MMBtu/hr Units Greater Than 20 MMBtu/hr | 15 ppm 9 ppm |
| Rule 4307 | Units 2.0 MMBtu/hr to 5.0 MMBtu/hr | 30 ppm |
| Rule 4308 | Units 0.075 MMBtu/hr to Less Than 2.0 MMBtu/hr | 20 ppm |
