II. EFFECT ON EMISSIONS

Complete this section ONLY for rules that, when implemented, will result in quantifiable changes in emissions. Attach refere nce(s) for emission

factor(s) and other information. Attach calculation sheet showing how the emi ssion information provided below was determined

.

Net Effect on Emissions: Increase Decrease N/A

Emission Reduction Commitment in SIP for this Source Category: 1.14 tons/d ay

Inventory Year Used to Calculate Changes in Emissions: 200 4 Area Affected: Imperial Valley Planning Area

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

Since i t's original adoptin in 2005, Rule 804 continues to appl y to non

- agricultural rural open areas more than 3 acres

(rural) or 0.5 (urban). The original analyis based on parcel data indicate d that over 99.5 percent of the existing parcels

were greater than 3 acres in size. Because assumptions have not changed and parcels are now being mitigated all

original Emission Reduction Commitments remain the same

VI. IMPACT ON AIR QUALITY PL AN

No Impact Impacts RFP Impacts attainment

Discussion: Once adopted into the Imperial County State Implementation Plan as BACM the Air District will be able to

better demonstrate rea sonable and appropriate measures are in place when Exceptional Event demonstrations are

developed and submitted for consideration to the US EPA for concurrence. Concurrence on Exceptional Event

demonstrations allows for the demonstrat ion of attainment of the PM10 National Ambient Air Quality Standard.
