Current through July 13, 2024
(a) The definitions
				in this Section supplement those definitions contained in W.S. §
									
										35-11-103;
(b) "Biosolids" means solid, semi-solid, or
				liquid residues 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.
(c) "Coal
				combustion residuals" means fly ash, bottom ash, boiler slag, and flue gas
				desulfurization materials generated from burning coal for the purpose of
				generating electricity by electric utilities and independent power
				producers.
(d) "Domestic septage"
				means 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. Domestic
				septage does not include grease removed from a grease trap at a
				restaurant.
(e) "Domestic sewage"
				means waste and wastewater that is primarily from human or household operations
				that is discharged to or otherwise enters a treatment works.
(f) "Groundwater" means subsurface water that
				fills available openings in rock or soil materials such that they may be
				considered water saturated under hydrostatic pressure.
(g) "Noncommercial pits and wells" means pits
				and wells that are operated by an oil and gas operator; that receive wastes
				from oil or gas wells on a lease, unit or communitized area; that are not
				operated primarily for profit; and that are owned or operated by any of the
				owners of the oil and gas wells that produce the received wastes.
(h) "Non-discharging treatment works" means
				any plant or other works used for the purpose of treating, stabilizing or
				holding wastes without any addition of any pollution or wastes to any Waters of
				the State.
(i) "Publicly owned or
				controlled facility" means a system owned or controlled by a municipality,
				county or water and sewer district.
(j) "Receiver" means any zone, interval,
				formation or unit in the subsurface into which fluids and pollutants are or may
				be discharged.
(k) "Sedimentation
				control structures" means any collection ditch, containment ditch or other
				conveyance or impoundment used to convey runoff to an impoundment or impound
				runoff for the purpose of settling out sediment or suspended solids. Non-soil
				strainer dikes, terraces, riprap and mulches primarily intended for soil
				conservation purposes and are not sedimentation control structures.
(l) "Sedimentation pond" means a primary
				sediment control structure designed, constructed, or maintained to control
				runoff to allow sediment to settle out. Dam-created impoundments, excavated
				depressions, and natural depressions are sedimentation ponds if they are
				designed, constructed, or maintained to control runoff to allow sediment to
				settle out and are larger than two acre-feet. Strainer dikes, terraces, riprap,
				check dams, mulches, or other secondary sediment control structures are not
				sedimentation ponds.
(m) "Sewage
				collection facility" means a sewerage system, including pipelines, conduits,
				storm sewers, pumping stations, force mains, and all other construction,
				devices, appurtenances, and facilities used for collection or conducting wastes
				to an ultimate point for treatment or disposal.
(n) "Treated wastewater" means domestic
				sewage discharged from a treatment works after completion of the treatment
				process.
(o) "Treatment works"
				means either a publicly or privately owned device or system used to treat
				either domestic sewage or a combination of domestic sewage and commercial or
				industrial waste of a liquid nature. Treatment works also include:
(i) Devices or systems that prepare biosolids
				or domestic septage for land application or surface disposal; and
(ii) Devices or systems that prepare treated
				wastewater for reuse.
