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

The U.S Environmental Protection Agency (EPA) issue d a formal limited approval and limited disapproval of the Rule 233, Biomass Boilers, in the Federal Registry, Volume 77, Number 12, on January 10, 2012. The l imited disapproval indicated that the nitrogen oxide (NOx) emission limit in Section 301 of 115 ppmv correcte d to 12% CO2 three-hour rolling average did not represent cu rrent Reasonably Available Control Technology (RACT ) and

should be lowered.

In response to the limited disapproval, the Distric t amended the Rule to add a NOx limitation of 68 pp mv corrected to 12% CO2 twenty-four hour block average. This is equivalent to the NOx limit of 90 ppmv correct to 3% O2 adopted by Yolo-Solano Air Quality Management Distr ict and San Joaquin Valley Unitified Air Pollution Control

District.

The Rule is applicable to two existing biomass boil ers in Placer County. Ammonia injection is used to control

NOx emissions. The NOx limit is considered achieva ble. Continuous emissions monitors (CEMS) measure N Ox,

CO and CO2 and will be utilized to enforce the new NOx limit.

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 imp lemented, will result in quantifiable changes in em issions. Attach reference(s) for emission factor(s )

and other information. Attach calculation sheet sh owing how the emission information provided below w as determined

.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Sourc e Category: Adoption of this rule was was original ly required by the Federal Clean Air Act, as amended in 1990, required adoption of source specific regulations for major sources of nitrogen oxides (NOx) pursuant to Sections 182(b)(2 )(C) and 182 (f) and subsequently adopted into the SIP in 1996,

When the rule was amended in 2009 to address startu p and shutdown issues the EPA declined to approve i t into the

SIP unless the NOx limit met current RACT. This am endment was adopted to satisfy the limited disappro val by EPA of Rule 233 and obtain approval into the State Impl ementation Plan (SIP).
