Oklahoma Administrative Code › Title 252 - Department of Environmental Quality › Chapter 515 - Management of Solid Waste › Subchapter 43 - Composting Facilities › Part 1 - GENERAL PROVISIONS › Section 252:515-43-2 - Definitions

Current through Vol. 41, No. 20, July 1, 2024
The following words and terms, when used in this
					 Subchapter, shall have the following meaning, unless the context clearly
					 indicates otherwise.
"Additives"
means any material that is mixed
					 with or added to feedstocks and bulking agents to create a favorable condition
					 for the composting process and includes urea, crushed egg shells, earthworms,
					 and bacterial or fungal inoculum.
"Aerated static pile composting"
means a
					 process in which decomposing organic material is placed in piles over an air
					 supply system that can be used to supply oxygen and control temperature for the
					 purpose of producing compost.
"Agricultural residuals"
means materials
					 generated by the customary and generally accepted activities, practices, and
					 procedures that farmers engage in during:
(A) the production and preparation for market of poultry,
					 livestock and associated farm products;
(B) the production and harvesting of agricultural crops
					 which include agronomic, horticultural, and silvicultural crops; and
(C) the production and cultivation of freshwater and
					 saltwater populations in the aqua cultural industry. Agricultural residuals do
					 not include manures managed as part of a Concentrated Animal Feeding Operation
					 (CAFO) license
"Biofilter"
means a material consisting of
					 bulking agents, shredded yard waste, or compost that is applied over the
					 composting mixture to control odors, dust, or vectors.
"Biosolids"
means primarily organically
					 treated wastewater materials from municipal wastewater treatment plants that
					 are suitable for recycling as amendments. This term is within the meaning
					 "sludge" referenced in 27A O.S. § 2-6-101(7). Biosolids are divided into
					 the following classes:
(A) Class A Biosolid meets the pathogen reduction
					 requirements of
					 40 CFR
					 §
											503.32(a);
(B) Class B Biosolid meets the pathogen reduction
					 requirements of
					 40 CFR
					 §
											503.32(b).
"Bulking agents"
means a material added to the
					 composting process to provide structural support, improve aeration, or absorb
					 moisture and includes wood chips, straw, clean untreated wood, shredded
					 newspaper, shredded cardboard, sawdust, shredded brush, and compostable
					 containers.
"Commercial composting facility"
means the
					 definition found at 27A O.S. § 2-10-103.
"Composting pad"
means the ground on which
					 composting activities take place. This may be subdivided by function, such as
					 "mixing pad", "composting pad", "curing pad" or "storage pad". An "all weather
					 composting pad" is one of sufficient construction, firmness and grading so that
					 composting equipment can manage the process during normal inclement weather,
					 including expected rain, snow and freezing temperatures.
"Contact water"
means water that has come in
					 contact with raw feedstocks or active composting piles. It does not include
					 water from curing piles, finished compost, or product storage piles.
"Curing"
means a continuation of the
					 composting process after the high heat stage during which stability and
					 maturity continues to increase. Compost enters the curing stage after
					 completing the high heat stage to further reduce pathogens and the requirements
					 for vector attraction reduction.
"Feedstock"
means material to be converted
					 under thermophilic conditions to a product with a high humus content classified
					 into different types for purposes of regulation under this Subchapter.
"Food processing residuals"
means organic
					 materials generated as a by-product of the industrial food processing sector
					 that are non-toxic, non-hazardous, and contain no sanitary wastewater. The term
					 does not include fats, oil, grease and Dissolved Air Flotation (DAF)
					 skimmings.
"Food residuals"
means pre- and post-consumer
					 food discards from households and the commercial/institutional sector including
					 but not limited to vegetables, fruits, grains, dairy products, meats, and
					 compostable foodservice ware/packaging that may be comingled.
"Household or backyard composting"
means any
					 person composting household waste that is located and utilized exclusively on
					 the owner's property.
"Industrial by-product"
means organic
					 materials generated by manufacturing or industrial processes that are
					 non-toxic, non-hazardous, contain no domestic wastewater, and pass the
					 PFLT.
"In-vessel composting"
means process in which
					 decomposing organic material is enclosed in a drum, silo, bin, tunnel, or other
					 container for the purpose of producing compost; and in which temperature,
					 moisture and air-borne emissions are controlled, vectors are excluded and
					 nuisance and odor generation minimized.
"Neighborhood composting"
means any person,
					 group of persons or geographically localized community within a town, city or
					 incorporated area composting feedstock that is composted and utilized
					 exclusively on property owned by the neighborhood or members of the
					 neighborhood.
"Nurseries, greenhouses, and garden stores
					 composting"
means any private or commercial nursery, greenhouse, or
					 garden store composting feedstock that is located and utilized exclusively on
					 property owned by the facility.
"Source separated organics"
means organic
					 material that has been separated from non-compostable material at the point of
					 generation, including but not limited to yard trimmings, food residuals,
					 vegetative materials, woody materials, and compostable products.
"Vermicomposting"
means the controlled and
					 managed process by which live worms convert organic materials into dark,
					 fertile, granular excrement or casting.
"Windrow composting"
means the processes in
					 which decomposing organic materials are placed in long piles for the purpose of
					 producing compost. The piles are periodically turned or agitated to assure all
					 parts of the decomposing material reach the desired stability.
"Woody materials"
means the residuals and
					 by-products of cutting trees, including but not limited to tree stumps,
					 sawdust, pallets, and dimensional lumber that has not been treated chemically
					 or with adhesives and coatings such as paint, glue, or any other visible
					 contaminant.
"Yard trimmings"
means leaves, grass
					 clippings, brush, garden materials, tree trunks, tree stumps, holiday trees,
					 and cuttings from trees or shrubs. Can also include vegetative materials
					 resulting from the use of commercial products, including but not limited to
					 discarded flowers, potted flowers, or grave blankets that do not include
					 plastic, metal, polystyrene foam, or other non-biodegradable
					 materials.
