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

Rule 806 is one of a series of seven rules which together form Regulation VIII, Fugitive Dust Control . Specifically

Rule 806 applies to Agricultural Operation Sites located within Imperial County. Adopted revisions to Rule 80 6

address the identified rule improvements , which ensure Best Available Control Measures, by the US EPA on its

limited approval/limited disapproval issued July 2010. Rule 80 6 includes new and/ or revised definitions for clarity of

applicability and a revision to requirements affecting the development and implementation of Conservation

Management Practices Plan . Specifically two new categories "Cropland Other" and "Windblown Dust" have been

added

. Editorial changes were made through out the rule for consistency.

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: 4.16 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 ts original adoption back in 2005 Rule 806 continues to require Conservation Management Practices (CMPs) at all

Agricultural Operations o ver 40 acres allowing for an efficiency factor above 90%

. With the addition of the two new CMP

categories the analysis indicates that the original SIP Reduction Commitment need not change . The two new CMP

categories are an enhancement and strengthen the rule.CALIFORNIA AIR RESOURCES BOARD

III. SOURCES/ATTAINMENT STATUS

District is: Attainment Nonattainment Split

Approximate Total Number of Small (<100 TPY ) Sources Affected by this Amendment:

Percent in Nonattainment Area: %

Number of Large ( > 100 TPY) Sources Controlled: None Percent in Nonattainment Area: N/A %

Name(s) and Locati on(s) (city and county) of Large ( > 100 TPY) Sources Controlled by Rule (Attach additional sheets as

necessary) : N/A

IV. EMISSION REDUCTION TECHNOLOGY

Does the Rule Include Emission Limits that are Continuous? Yes No

If Yes, Those Limits are in Section(s) of the Rule.

Other Methods in the Rule for Achieving Emission Reductions are: The development and implementation of a Dust

Control Plan with CMP's which limit visible emissions to below 20% opacity and require stabilization of surfaces

.

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): Work Practice Standards in Section(s): E

Recordkeeping Requirements in Section(s): H Reporting Requirements in Section(s): HCALIFORNIA AIR RESO URCES BOARD

VI. IMPACT ON AIR QUALITY PLAN

No Impact Impacts RFP Impacts attainment

Discussion: Once adopted into the Imperial County State Implementation Plan , enhancing BACM

, the Air District will be

able to better demonstrate reasonable 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

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