Compost animal waste removed from the housing with an aerated static pile vented to a control device with at least 80% control efficiency designed, constructed, operated, and maintained in accordance with NRCS Agricultural Waste Management Field Handbook Chapter 10 Section 651.1004, or more recent NRCS guidance.

(D). Handling of Manure in Liquid Form: Owners/operators that handle manure in a liquid form shall incorpo rate at least one (1) of the following mitigation measures:

Class One Mitigation Measures 1

. Manage the facility such that only storm water and water used to wash eggs enters the lagoon. 2. a. Use phototrophic lagoons, or b. Use an anaerobic treatment lagoon designed, constructed, maintained, and operated in accordance with NRCS Agricultural Waste Management Field Handbook Chapter 10 Section 651.1004, or more recent NRCS guidance. 3. Remove solids from the waste system with a solid separator system, p rior to the waste entering the lagoon that is designed, constructed, operated, and maintained in accordance with NRCS Practice Standard 629 (Waste Treatment) , or more recent NRCS standard

. 4. Maintain lagoon at a pH between 6.5 and 7.5. 5

. Implement alt ernative mitigation measure(s), not listed above, subject to approval of the Executive Officer.

Class Two Mitigation Measures 6

. a. Use aerobic lagoons designed, constructed, maintained, and operated to the recommendations in NRCS Agricultural Waste Mana gement Field Handbook Chapter 10 Section 651.1004 or more recent NRCS guidance, or b. Use a mechanically aerated lagoon designed, constructed, maintained, and operated according to the recommendations in NRCS Agricultural Waste Management Field Handbook Ch apter 10 Section 651.1004 or more recent NRCS guidance, or c. Maintain organic loading in the lagoon that is less than 3.5 mg (dry weight)/mL, or total volatile solids is less than 3.5 mg/mL. 7

. Use additional non

- standard equipment or chemicals on the so lid separator system, such as roller or screw presses or chemical coagulants and flocculants that increase the percent of solid separation achieved by the separator and is approved by the Executive Officer

. Cover the lagoon or storage pond and vent to a biofilter or a control device with at least 80% control efficiency.

Note: 1. An owner/operator may temporarily suspend utilization of a mitigation

meas ure provided all of the following requirements are met: (a) It is determined by a certified veterinarian or nutritionist

that the mitigation measure may be detrimental to animal health or that suspension of the mitigation measure is necessary for the animal to molt

, and (b) The operator notifies the District, within forty

- eight (48) hours of the veterinarian's or nutritionist’s determination, that a measure is being temporarily suspended, and (c) If such a situation exists, or is expected to exist for longer than thirt y (30) days, the owners/operators shall, within that thirty (30) day period, submit a new mitigation measure to be implemented in lieu of the mitigation measure that was suspended.

2. An owner/operator may substitute a mitigation measure from one section in the applicable table (tables 2 through 6) for a mitigation measure in another section of the applicable table, provided it is demonstrated , to the satisfaction of the Executive Officer, that the substitution would result in equal or greater emission reduct ions. Substituted measures shall be requested by submittal of an application to modify the mitigation plan required by Rule 223(c)(4) with remittance of fees required by Rule 306, and shall be included as permit requirements. 3. For the purposes of this atta chment, the term “Executive Officer” when used for the approval of alternate mitigation measures means the Executive Officer of the SCAQMD, CARB, and U.S. EPA.
