RULE 1127. EMISSION REDUCTIO NS FROM LIVESTOCK WASTE

(a) Purpose The purpose of this rule is to reduce ammonia, VOC, and PM10 emissions from
lives tock waste.

(b) Applicability This rule applies to dairy farms and rela ted operations such as heifer and calf
far ms and the manure produced on them. It also applies to manure processing operations, such as composting ope rations and anaer obic digesters.

(c) Definitions For the purpose of this rule, the following definitions shall apply: (1) ALTERNATIVE MANURE COM POSTI NG OPERATION means an invessel composting operation that does not meet the requirements of subdivision (d) of Rule 1133.2 and that composts either livestock manure only, or manure and green material am endments only. Biosolids and food
waste cannot be used as feedstocks. (2) ANAE ROBIC DIGESTER is a tank or vessel system that excludes oxygen and in which a sludge or liquid effl uent is modified by the action of anaerobic bacteria. The remaining solids from the process can be used as a soil amendment or further composted or otherwise processed. (3) DAIRY FARM is an operation on a prope rty, or set of properties that are contiguous or separated only by a public right-of-way, whi ch is directly related to raising cows or producing milk from cows for the purpose of making a profit or for a livelihood. Heifer and calf farms are included in this definition of dairy farms. (4) ENGINEE RED WASTE MANAGEME NT PLAN is a plan for a wastewater management system that is designed, constructed, operated and maintained to comply with the wastewater containment requirements of the Santa Ana Regional Water Quality Control Board. (5) EXISTING DAIRY OP ERATION is a da iry farm being operated as of (the date of rule adoption). (6) GREEN MATERIAL means any plant ma terial th at is separated at the point of generation and contains no greater than 1.0 percent of physical

demolition debris. (6) MANURE PROC ESSING OPERATION is an operation that receives manure from livestock operations a nd processes it for use. Such processing includes, but is not limited to, composting operations producing fertilizer and/or soil amendments, and an aerobic digesters. (7) OPERATOR is any person, people, or enti ty that owns or operates a dairy
far m or manure processing operation subj ect to the requirements of this

corral: (A) Scrape or harrow before 9 am onl y unless the moisture content of the manure is greater than 20% throughout the corral, as determined by an moisture meter in accordance with paragraph (h)(1); OR (B) Clear co rrals such that an ev en surface of compacted manure remains on top of the soil and do not scrape down to soil level; OR (C) Water corral before m anure removal to reduce dust through increased surface moisture. This measure is not required for lactating cows. (2) Minim ize excess water in corrals by: (A) identifying and elim inating water leaks from trough and trough piping; and (B) com plying with corral drainage st andards specified in the dairy’s Engineered Waste Management Plan.
