RULE 10 

LARGE CONFINED ANIMAL FACILITIES 

(Adopted July 19, 2006) 

2-10-100 GENERAL 

2-10-101 Description: The purpose of this Rule is to reduce emissions of air contaminants 

from large confined animal facilities through control measures established during 

permit review. 

2-10-200 DEFINITIONS 

2-10-201 Confined Animal Facility includes, but is not limited to, any structure, building, 

installation, barn, corral, coop, feed storage area, milking parlor, or system for the 

collection, storage, treatment, and distribution of liquid and solid manure, if 

domesticated animals, including, but not limited to, cattle, calves, horses, sheep, 

goats, swine, rabbits, chickens, turkeys, or ducks are corralled, penned, or otherwise 

caused to remain in restricted areas for commercial agricultural purposes and 

feeding is by means other than grazing. 

2-10-202 Large Confined Animal Facility: A confined animal facility that maintains on any 

one day: 1,000 or more milk-producing dairy cows; 3,500 or more beef cattle; 7,500 

or more calves, heifers, or other cattle; 100,000 or more turkeys; 650,000 or more 

chickens other than laying hens; 650,000 or more laying hens; 3,000 or more swine; 

15,000 or more sheep, lambs, or goats; 2,500 or more horses; 650,000 or more 

ducks; or 30,000 or more rabbits or other animals. 

2-10-300 STANDARDS 

2-10-301 Emissions Mitigation Measures: The APCO shall include in any permit to operate 

a large confined animal facility required under Regulation 2, Rule 1 permit conditions 

to implement control measures that represent reasonably available control 

technology to reduce emissions of POC, NOx, and PM10 from the facility. The APCO 

shall establish a reasonable compliance schedule for facilities to implement these 

control measures within one year of the date on which the permit is issued. 

2-10-302 Update of Emissions Mitigation Measures: The APCO shall review each permit to 

operate issued to a large confined animal facility within three years of the date of 

original permit issuance, and every three years thereafter, and update the permit 

conditions to meet the requirements of Section 301 based on changes in the 

operation, or the feasibility of mitigation measures. 

2-10-400 ADMINISTRATIVE REQUIREMENTS 

2-10-401 Content of Permit Application: The owner or operator of a large confined animal 

facility shall include in any permit application required under Regulation 2, Rule 1: 

401.1 Emissions Inventory: All information necessary to prepare an emissions 

inventory of all regulated air pollutants emitted from the facility, including but 

not limited to, POC, NOx, and PM10 and fugitive emissions, using emission 

factors approved by the California Air Resources Board. 

401.2 Emissions Mitigation Plan: An emissions mitigation plan that demonstrates 

that the facility will implement control measures that represent reasonably 

available control technology to reduce emissions of POC, NOx, and PM10, 

including a reasonable compliance schedule to implement these control 

measures within one year of initial permit issuance.

2-10-402 Public Notice and Comment: Prior to approving the initial permit to operate for a 

large confined animal facility the APCO shall, within 10 days of notification of the 

applicant, cause to have published in at least one newspaper of general circulation 

within the District, and on the District’s website, a notice inviting written public 

comment on the draft permit for a 30 day period following the date of publication. A 

copy of this notice shall be provided to any person who requests such specific 

notification in writing. A copy of the draft permit shall be sent to the ARB and each 

adjacent air district. 

2-10-403 Public Inspection: The APCO shall make available for public inspection, at the 

District headquarters, the information submitted by the applicant, and the draft permit 

including any applicable conditions. In making information available for inspection, 

the confidentiality of trade secrets, as designated by the applicant prior to completion 

of the application, shall be handled in accordance with Section 6254.7 of the

decision to the applicant and to the ARB. 

2-10-500 MONITORING AND RECORDS 

2-10-501 Recordkeeping: The owner or operator of a large confined animal facility shall keep 

records that specify the numbers of animals maintained daily and such other 

information as may be required by the APCO. Such records shall be maintained at a 

central place of business for a period of not less than three years and shall be made 

available upon request to the APCO.
