addition, it sets forth more stringent thresholds and mitigation measures. 

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 implemented, will result in quantifiable changes in emissions. Attach reference(s) for emission 

factor(s) and other information. Attach calculation sheet showing 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: NONE

Inventory Year Used to Calculate Changes in Emissions: 2014 Area Affected: Salton Sea Air Basin

Future Year Control Profile Estimate (Provide information on as many years as possible):

Research by the Imperial County Air Pollution Control District found that there ae 26 Beef Feedlots and 1 Dairy which will 

be directly impacted by Rule 217. It is estimated that the total reduction of VOC's will be 234.8 tons per year and in addition 

future ammonia reductions will be estimated.

VI. IMPACT ON AIR QUALITY PLAN

 No Impact Impacts RFP Impacts attainment

Discussion: Based on the data, this Rule should generate a reduction of approximately 234.8 ton of VOC's per year. 

Ammonia reductions will be estimated at a future date.
