Narrative Summary of New Rule or Rule Changes: ( ) New Rule ( X ) Amended : Revisions to these rules will change the applicability so that

boilers at 1 million BTUs or larger will be transferred from Rule 74.1 1.1 to Rule 74.15.1. In Rule 74.11.1, a new NOx limit of 20 ppm will apply to

units for sale from 400,000 BTUs to 1 million BTUs effective January 1, 2013. On January 1, 2014, all units for sale from 7 5,000 BTUs to 400,000

BTUs/hr, except pool heaters, will be subject to NOx limits of 20 ppm. In Rule 74.15.1, effective on January 1, 2013, new boilers from 1 million

BTUs/hr to 2 million BTUs/hr will subject to the 20 ppm NOx limit. Also, new annual NOx and CO screenings will be required f or all boilers

(except low

- use boilers) while the source test requirements for boilers from 1 million BTUs/hr to 2 million BTUs/hr will be required ever y 4 years

rather than 2 years. In summary, only new boilers are subject to the new 20 ppm NOx limits.

Pollutant(s) Re gulated by the Rule (Circle): ROG NOx SO2 PM10 CO TAC

II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emission. Attach referen ce(s) for emission factor(s) and other

informa tion. Attach calculation sheet showing how the emissions information provided below was determined. See staff report Appendi x A for emission calculations.

Net Effect on Emissions: ( ) Increase ( X ) Decrease ( ) N/A No impact on emissions. See attached staff report for emission reduction

calculations. The net effect of both rules is to reduce NOx emissions by 11.3 tons per year.
