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

Proposed Rule 1127 implements 2003 AQMP Control measure WST-01 and certain Senate Bill (SB) 700 requirements for dairy operations. Its purpose is to reduce VOC, ammonia and PM10 emissions from dairy manure. Rule 1127 affects dairy and related operations such as heifer and calf ranches, as well as manure processing operations such as composters and digesters. It establishes on-farm best management practices, manure disposal require ments, and approval requirements for manure

processors.

Pollutant(s) Regulated by the Rule (Check): ROG (NOx) SO2 (Administrative and Protocol Only) (CO) PM TAC (name): Ammonia

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 Category: 4.2 tons per day VOC & 8.7 tons per day Ammonia in 2006; 4.8 tons per day VOC & 8.7 tons per da y Ammonia in 2010 (2003 AQMP Control Measure WST-01)

Inventory Year Used to Calc ulate Changes in Emissions: 2006 & 2010 Area Affected: SCAQMD

Baseline Inventory in the SIP for the Control Measure: 12.1 tons per day VOC & 21.2 tons per day Ammonia in 1997; 11.0 tons per day VOC & 19.3 tons per day Ammonia in 2006 & 2010

Emissions Reduction Commitment in the SIP for the Control Measure: 4.2 tons per day VOC & 8.7 tons per day Ammonia in 2006; 4.8 tons per day VOC & 8.7 tons pe r day Ammonia in 2010 (2003 AQMP Control Measure WST01)

Revised Baseline Inventory (if any): 6.35 tons per day VOC & 18.0 tons per day Ammonia in 2006; 5.8 tons per day VOC & 16.43 tons per day Ammonia in 2010 (see discussion below)

Revised Emission Reduction Estimate (if developed): 2.56 tons per day VOC & 7.26 tons per day Ammonia in 2006; 2.47 tons per day VOC & 6.99 tons per day Ammonia in 2010 (see discussion below)

The baseline emissions were adjusted using the lat est emission factors and emission methodologies. In addition, emission reductions account for reductions resulting from dairy relocations and water quality regulations enacted in 1999. Emission reductions due to Rule 1127 alone are 1.19 tons per day VOC & 3.37 tons per day Ammonia in 2006; 1.16 tons per day VOC & 3.27 tons per day Ammonia in 2010.

III. SOURCES/ATTAINMENT STATUS

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No If Yes, Those Limits are in Section(s)

Other Methods in the Rule for Ac hieving Emission Reductions are: Rule 1127 achieves reductions by implementation of best management practices (subdivision (d)) a nd manure disposal requirements (subdivision (d)).

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: The rule best management practices to reduce emissions of VOC and ammonia from this source category. Secondary emissions of PM10 (ammonia as precursor) will also be reduced.
