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

This Rule 414 amendment establishes NOx emission limit s for water heaters, boilers, and process heaters with

rated heat input capacities ranging fr om 75,000 to 1,000,000 Btu/hr, and sets more stringent NOx limits for units

rated below 75,000 Btu per hour. The emission limits are based on those contained in SCAQMD Rule 1146.2

(Emissions of Oxides of Nitrogen from Large Water Heaters and Small Boilers and Process Heaters) and

SCAQMD Rule 1121 (Control of Nitrogen Oxides from Re sidential- Type, Natural Gas-Fired Water Heaters).

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

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, w ill result in quantifiable changes in emissions. Attach referenc e(s) for emission factor(s)

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

.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Ca tegory: The 2009 8-hour ozone attainment plan includes a

commitment to reduce NOx emissions from water heater s, boilers and process heaters rated less than 1,000,000

Btu/hr by 0.71 tpd in the Sacramento district in 2018. This amendment achi eves a NOx reduction of 0.71 tpd in 2018

and therefore satisfies the plan commitment.
