Rule No(s): 352 Date Amended: October 20, 2011

Rule Title(s): Natural Gas-Fired Fan-Type Central Furnaces and Small Water Heaters

Date Submitted to ARB: October 25, 2011

If an Amended Rule, Date Last Amended (or Adopted): April 17, 1997 

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

The primary objective of this rule revision project was to reduce the small water heater NOx emissions limit from 

55 ppmv to 15 ppmv. The revision also added a sell-through provision that enable distributors to see exiting water 

heaters that do not meet the 15 ppmv limit until July 1, 2012. Additionally, the rule title was revised: "Natural GasFired Fan-Type Central Furnaces and Residential Small Water Heaters", the definition for "Natural gas" was 

amended and the ASTM Methods were updated. Lastly, the NOx emissions limit for natural gas-fired fan-type 

central furnaces was not revised and remains unchanged at 55 ppmv.

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