Narrative Summary of New Rule or Rule Changes: New Rule (X) Amended Rule ( ) 

The purpose of Rule 11.2, Confined Animal Facilities Permit Program, is to implement the requirements of Section

40724.6 of the California Health and Saftey Code (CH&SC). This section of the CH&SC contains new requirements for

districts and the confined animal facility (CAF) industry (i.e. dairies, beef feedlots, chicken layer/broiler operations). Rule

11.2 is a permit program that includes permitting, application, and emission mitigation requirements, program fees, and

all other regulatory components needed to establish this new District permit program. The rule requires the use of Best

Available Retrofit Control Technology (BARCT), for existing CAF operations, and Best Available Control Technology

(BACT), for new or modified CAF operations, to reduce emissions from pollutants that contribute to the nonattainment of

any ambient air quality standard.

Pollutant(s) Regulated by the Rule (Check): ROG (X) NOx ( ) SO2 ( )

Approximate Total Number of Small (<100 TPY) Sources Affected by this Amendment: 2 

Percent in Nonattainment Area: 100 %

Number of Large (> 100 TPY) Sources Controlled: 0 Percent in Nonattainment Area: N/A %

Name(s) and Location(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 (X)

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

Other Methods in the Rule for Achieving Emission Reductions are: Rule 11.2 requires the use of Best Available Retrofit

Control Technology (BARCT), for existing CAF operations, and Best Available Control Technology (BACT), for new and

modified CAF operations, to reduce emissions from pollutants that contribute to the nonattainment of any ambient air

quality standard.

V. OTHER REQUIREMENTS

The Rule Contains:

Emission Limits in Section(s): N/A Work Practice Standards in Section(s): N/A 

Recordkeeping Requirements in Section(s): 500 Reporting Requirements in Section(s): 500

VI. IMPACT ON AIR QUALITY PLAN

No Impact (X) Impacts RFP ( ) Impacts attainment ( )

Discussion: As a result of the previous air quality permit exemption for confined animal facilities (CAFs), there is little

information regarding emissions from their operation. Currently, state-wide research projects are being conducted on CAF

emissions and emission controls. As new research data becomes available for District review, this may change the District's

methodology (i.e. emission factors and emission control efficiencies) in quantifying emissions and emission reductions from

CAFs. Therefore, although Rule 11.2 is expected to reduce emissions from CAF operations, the District will not claim

emission reductions at this time.
