<br /> Chapter 3.1 Composting Operations Regulatory Requirements
<br /> • Article 1.General
<br /> Section 17850.Authority and Scope.
<br /> (a)This Chapter is adopted pursuant to and for the purpose of implementing the California Integrated Waste Management Act
<br /> of 1989(Act)commencing with Section 40000 of the Public Resources Code,as amended.These regulations should be read
<br /> together with the Act.
<br /> (b)This Chapter implements those provisions of the Act relating to composting.Nothing in this Chapter is intended to limit the
<br /> power of any federal, state,or local agency to enforce any provision of law that it is authorized or required to enforce or
<br /> administer.
<br /> (c)Biological decomposition of organic material can be both a naturally occurring or artificially controlled process.This
<br /> Chapter establishes standards and regulatory requirements for intentional and inadvertent composting resulting from the
<br /> storage or handling of feedstock,compost,or chipped and ground materials.
<br /> (d)Nothing in these standards shall be construed as relieving any owner,operator,or designee from the obligation of obtaining
<br /> all required permits,licenses,or other clearances and complying with all orders,laws,regulations,or reports,or other
<br /> requirements of other regulatory or enforcement agencies,including but not limited to, local health entities,regional water
<br /> quality control boards,air quality management districts or air pollution control districts,local land use authorities,and fire
<br /> authorities.
<br /> Section 17852.Definitions.
<br /> For the purposes of this Chapter:
<br /> (a)"Active Compost"means compost feedstock that is in the process of being rapidly decomposed and is unstable.Active
<br /> compost is generating temperatures of at least 50 degrees Celsius(122 degrees Fahrenheit)during decomposition;and is
<br /> releasing carbon dioxide at a rate of at least 15 milligrams per gram of compost per day,or the equivalent of oxygen uptake.
<br /> (b)"Additives"means material mixed with feedstock or active compost in order to adjust the moisture level,carbon to nitrogen
<br /> ratio,or porosity to create a favorable condition.Additives include,but are not limited to,fertilizers and urea.Additives do not
<br /> include septage,sewage,or compost feedstock.
<br /> (c)"Aerated Static Pile"means a composting process that uses an air distribution system to either blow or draw air through the
<br /> • pile.Little or no pile agitation or turning is performed.
<br /> (d)"Aerobic Decomposition"means the biological decomposition of organic substances in the presence of oxygen.
<br /> (e)"Agricultural Commodities"or"Agricultural Materials"means the products of farms and ranches and items processed from
<br /> these products,as defined in Division 21,Part 2,Chapter 1, Section 58619 of the Food and Agricultural Code,including any
<br /> agricultural,horticultural,aquacultural,silvicultural,floricultural,vermicultural,or viticultu1 product. �C-4,k P%kVW -9
<br /> -491(f)"Agricultural Material Composting Operation'_'means an operation that processes green and animal materials derived from
<br /> agricultural com odities.`additives,and/or amendments into compost. "Agricultural Material Composting Operation"does not
<br /> includer activities excluded from regulation in Section 17855. "Agricultural Material Composting Operations"include
<br /> operations that use clean green material,as defined in Subdivision(k)of this Section,if the clean green material portion does
<br /> not exceed the agricultural commodities portion of active compost on-site annually.
<br /> (g)"Amendments"means materials added to stabilized or cured compost to provide attributes for certain compost products,
<br /> such as product bulk,product nutrient value,product pH,and soils blend.Amendments do not include septage,sewage,or
<br /> compost feedstock.
<br /> (h)"Anaerobic Decomposition"means the biological decomposition of organic substances in the absence of oxygen.
<br /> (i)"Animal Material"means any material derived from animal products that are for consumption by humans or animals.,The:
<br /> sources of these products include,but are not limited to,agriculture,food manufacturing and processing industries,zestaurants,
<br /> hospitals,and food distributors. "Animal Material"is either separated at the point of generation,or separated at a centralized
<br /> facility that employs methods to minimize contamination.The composting of mammalian flesh,organs,unprocessed,hide,
<br /> blood,bone and marrow is prohibited,except when from the food service industry.Animal material does not include manure.
<br /> 0)"Animal Material Composting Facility" is a facility that processes animal material and additives and amendments into
<br /> compost.A facility that composts green material in addition to animal material shall be considered an animal material
<br /> composting facility. "Animal Material Composting Facility"does not include activities excluded from regulation in Section
<br /> 17855,and operations that constitute"Agricultural Material Composting Operations."
<br /> (k)"Chipping and Grinding"means an activity that mechanically reduces the size of organic matter.
<br /> P (1)"Clean Green Material"or"Clean Green"means green material that is processed by apermittg"Qlid wastef ili in order
<br /> to reduce contamination to the greatest extent possible as set forth in Section 17868.4.Tree and landscape trimming materials
<br /> that have never been combined with other waste materials are considered"Clean Green Materials."
<br /> (m)"Composting Facility"means a facility that is operated for the purpose of producing compost,as defined in Division 3.0,
<br /> Part 1,Chapter 2,Section 40116 of the Public Resources Code.A"Composting Facility" includes:
