Current through July 13, 2024
The following definitions supplement those definitions
					 contained in Section
											35-11-103 of the Wyoming
					 Environmental Quality Act.
(a) "Apply
				  biosolids or biosolids applied to the land" means land application of
				  biosolids.
(b) "Base flood" is a
				  flood that has a one percent (1%) chance of occurring in any given year (i.e.,
				  a flood with a magnitude equaled once in 100 years).
(c) "Biosolids" are solid, semi-solid, or
				  liquid residue generated during the treatment of domestic sewage in a treatment
				  works. Biosolids include, but are not limited to, domestic septage; scum or
				  solids removed in primary, secondary, or advanced wastewater treatment
				  processes; and a material derived from biosolids. Biosolids do not include ash
				  generated during the firing of biosolids in a biosolids incinerator or grit and
				  screenings generated during preliminary treatment of domestic sewage in a
				  treatment works.
(d) "Biosolids
				  management facility" is any treatment works, land application system or person
				  who prepares or applies biosolids to the land and the owner/operator of a
				  surface disposal site.
(e) "Cover
				  crop" is a small grain crop, such as oats, wheat, or barley, not grown for
				  harvest.
(f) "CWA" means the Clean
				  Water Act , 333 U.S.C.
				  1251 et seq.
(g) "Domestic septage" is either liquid or
				  solid material removed from a septic tank, cesspool, portable toilet, Type III
				  marine sanitation device, or similar treatment works that receives only
				  domestic sewage. Domestic septage does not include liquid or solid material
				  removed from a septic tank, cesspool, or similar treatment works that receives
				  either commercial wastewater or industrial wastewater and does not include
				  grease removed from a grease trap at a restaurant.
(h) "Domestic sewage" is waste and wastewater
				  from humans or household operations that is discharged to or otherwise enters a
				  treatment works.
(i) "Dry weight
				  basis" means calculated on the basis of having been dried at 105 degrees
				  Celsius until reaching a constant mass (i.e., essentially 100 % solids
				  content).
(j) "EPA" means the
				  United States Environmental Protection Agency.
(k) "Feed crops" are crops produced primarily
				  for consumption by animals.
(l)
				  "Fiber crops" are crops, such as flax and cotton, that are not produced for
				  consumption.
(m) "Food crops" are
				  crops consumed by humans. These include, but are not limited to, fruits,
				  vegetables, and tobacco.
(n)
				  "Ground water" is subsurface water that fills available openings in rock or
				  soil material such that they may be considered water saturated under
				  hydrostatic pressure.
(o)
				  "Industrial wastewater" is wastewater generated in a commercial or industrial
				  process.
(p) "Municipality" means a
				  city, town, borough, county, parish, district, association, or other public
				  body (including an intermunicipal agency of two or more of the foregoing
				  entities) created by or under state law; or a designated and approved
				  management agency under section 208 of the CWA, as amended. The definition
				  includes a special district created under state law, such as a water district,
				  sewer district, sanitary district, utility district, drainage district, or
				  similar entity, or an integrated waste management facility as defined in
				  section 201(e) of the CWA, as amended, that has as one of its principal
				  responsibilities the treatment, transport, use, or surface disposal of
				  biosolids.
(q) "Permitting
				  authority" is the EPA and/or the Department of Environmental Quality, Water
				  Quality Division.
(r) "Person who
				  prepares biosolids" is either the person who generates biosolids during the
				  treatment of domestic sewage in a treatment works or the person who derives a
				  material from biosolids.
(s) "Place
				  biosolids or biosolids placed" means disposal of biosolids on a surface
				  disposal site.
(t) "Pollutant" is
				  an organic substance, an inorganic substance, a combination of organic and
				  inorganic substances, or a pathogenic organism that, after discharge and upon
				  exposure, inges-tion, inhalation, or assimilation into an organism either
				  directly from the environment or indirectly by ingestion through the food
				  chain, could, on the basis of information available to the administrator of
				  EPA, cause death, disease, behavioral abnormalities, cancer, genetic mutations,
				  physiological malfunctions (including malfunction in reproduction), or physical
				  deformations in either organisms or offspring of the organisms.
(u) "Pollutant limit" is a numerical value
				  that describes the amount of a pollutant allowed per unit amount of biosolids
				  (e. g., milligrams per kilogram of total solids); the amount of a pollutant
				  that can be applied to a unit area of land (e. g., kilograms per hectare); or
				  the volume of a material that can be applied to a unit area of land (e.g.,
				  gallons per acre).
(v) "Runoff" is
				  rainwater, leachate, or other liquid that drains overland on any part of a land
				  surface and runs off of the land surface.
(w) "Store or storage of biosolids" is the
				  placement of biosolids on land on which the biosolids remains for two years or
				  less. This does not include the placement of biosolids on land for
				  treatment.
(x) "Treat or treatment
				  of biosolids" is the preparation of biosolids for final use or disposal. This
				  includes, but is not limited to, thickening, stabilization, and dewatering of
				  biosolids. This does not include storage of biosolids.
(y) "Treatment works" is either a federally
				  owned, publicly owned, or privately owned device or system used to treat
				  (including recycle and reclaim) either domestic sewage or a combination of
				  domestic sewage and industrial waste of a liquid nature. This definition is
				  applicable to this chapter only and has a more limited application than the
				  same term as defined in W.S. W.S.
