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

Class Two Mitigation Measures 5. Store all removed animal waste in an enclosure v ented to a control device with at least 80% control efficiency. 6. Send at least 51% of the animal waste removed fr om site to a digester, with a control device a control efficiency of at least 80% , within seventy two (72) hours of removal from housing. The digester shall be designe d, constructed, maintained, and operated in accordance with NRCS Agricultural Waste Management Field Handbook Chapter 10 Section 651.1006, or more recen t NRCS guidance. 7. Compost animal waste removed from the housing wi th an aerated static pile vented to a control device with at least 80% control effic iency designed, constructed, operated, and maintained in accordance with NRCS Ag ricultural Waste Management Field Handbook Chapter 10 Section 651.10 04, or more recent NRCS guidance.

Class One Mitigation Measures 1

Use an anaerobic treatment lagoon designed, con structed, maintained, and operated in accordance with NRCS Agricultural Waste Management Field Handbook Chapter 10 Section 651.1004, or more recen t NRCS guidance. 3. Remove solids from the waste system with a solid separator system, prior to the waste entering the lagoon that is designed, constru cted, operated, and maintained in accordance with NRCS Agricultural Waste Management Field Handbook Chapte r 10 Section 651.100 4 Practice Standard 629 (Waste Treatment) , or more recent NRCS guidance standard

. 4. Maintain lagoon at a pH between 6.5 and 7.5. 5. Implement alternative mitigation measure(s), not listed above, subject to approval of the Executive Officer.

Use aerobic lagoons designed, constructed, ma intained, and operated to the recommendations in NRCS Agricultural Waste Manageme nt Field Handbook Chapter 10 Section 651.1004 or more recent NRCS gui dance, or b. Use a mechanically aerated lagoon designed, cons tructed, maintained, and operated according to the recommendations in NRCS A gricultural Waste Management Field Handbook Chapter 10 Section 651.10 04 or more recent NRCS guidance, or c. Maintain organic loading in the lagoon that is l ess 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 chemica ls on the solid separator system, such as roller or screw presses or chemical coagula nts and flocculants that increase the percent of solid separation achieved by the sep arator and is approved by the Executive Officer. 8. Cover the lagoon or storage pond and vent to a b iofilter or a control device with at least 80% control efficiency.

Note: 3. 1. An owner/operator may temporarily suspend utilizati on of a mitigation

measure provided all of the following requirements are met: (a) It is determined by a certified veterinarian or nut ritionist that the mitigation measure may be detrimental to animal hea lth or that suspension of the mitigation measure is necessary f or the animal to molt, and (b) The operator notifies the District, within forty-ei ght (48) hours of the veterinarian's or nutritionist’s determination, tha t a measure is beingProposed Rule 223 Appendix A (Cont.)
