RULE 1127. EMISSION REDUCTIO NS FROM LIVESTOCK WASTE

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

(b) Applicability This rule applies to dairy farms and rela ted operations such as heifer and calf farms 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 COMPOSTI 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) ANAEROBIC 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, which 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) ENGINEERED 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 OPERATION is a da iry farm being operated as of (the date of rule adoption). (6) GREEN MATERIAL means any plant ma terial that is separated at the point of generation and contains no greater than 1.0 percent of physical

1127-1Rule 1127 (cont.) (Adopted August 6, 2004)

contaminants by weight, and meets the requirements of the California Code of Regulations – Title 14, section 17868.5. Green materials includes, but is not lim ited to, yard trimmings, untreated wood wastes, natural fiber products, and construction and demolition wood waste.
Green material does not include food material, biosolids, mixed solid waste, material processes from co mmingled collection, wood containing lead-based paint or wood preserva tive, mixed construction or mixed
demolition debris. (6) MANURE PROCESSING 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 farm or manure processing operation subj ect to the requirements of this
rule.

(d) Best Management Practices On or after December 1, 2004, a dairy operator shall: (1) Use one of the following procedur es when removing manure from a
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 corrals 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 manure removal to reduce dust through increased surface moisture. This measure is not required for lactating cows. (2) Minimize excess water in corrals by: (A) identifying and eliminating water leaks from trough and trough piping; and (B) complying with corral drainage st andards specified in the dairy’s Engineered Waste Management Plan. (3) Pave feedlanes, where present, at least 8 feet on the corral side of the
feedlane fence.
