Current through July 13, 2024
The following definitions supplement those contained in
					 W.S.
					 35-11-103 of the Wyoming Environmental

				  lands whose natural state has been or will be disturbed as a result of the
				  operations.
(b) "Campground" means
				  a parcel or tract of land under the control of a person at which sites are
				  offered for the use of the public or members of an organization either free of
				  charge or for a fee, for the establishment of temporary living quarters for two
				  or more recreational units.
(c)
				  "Commercial/industrial waste and wastewater facilities" means any facility not
				  defined as a municipal or single family residence facility.
(d) "Construction" shall encompass the
				  materials used, installation procedures and tolerances, and testing and
				  disinfection requirements.
(e)
				  "Feedlot" means the concentrated confinement of animals or poultry in pens or
				  houses for meat, milk, or egg production or the stabling of animals or poultry
				  for a period of forty-five (45) days or more in a twelve (12) month period when
				  forage or crops are not grown in the area of confinement.
(f) "Hazardous substance" means any matter of
				  any description including petroleum related products and radioactive material
				  (substance) that, when discharged into any Waters of the State, presents an
				  imminent and substantial hazard to public health or welfare. This definition
				  includes all materials (substances) so designated by the U. S. Environmental
				  Protection Agency in the Federal Register for March 13, 1978 (Part III), Water
				  Programs, Hazardous Substances.
(g)
				  "Land application/treatment" means the application of wastes or wastewater to
				  the land at a predetermined rate for the purpose of disposal or treatment by
				  any or all of the following processes: degradation, plant uptake, assimilation
				  or accumulation in the soil profile from filtration.
(h) "Maximum daily demand" means the largest
				  daily water use rate that would occur during the calendar year.
(i) "Maximum hourly or peak hourly demand"
				  means the largest water use rate that would occur during any one hour during
				  the year. The maximum hourly demand may or may not occur during the maximum
				  daily demand period.
(j) "Mobile
				  home park" means a parcel or tract of land under the control of a person upon
				  which two (2) or more mobile homes are located on a continual or seasonal
				  nonrecreational basis, regardless of whether a charge is made
				  therefore.
(k) "Off-channel" means
				  the interception of a drainage way that collects runoff only from disturbed
				  areas.
(l) "On-channel" means the
				  interception of a drainage way that collects runoff from both disturbed and
				  undisturbed areas.
(m) "Permanent
				  pool level" means the elevation in a sedimentation pond or sediment control
				  structure below which the water will not be discharged by an outlet structure
				  or by pumping.
(n) "Pond/lagoon"
				  means a manmade or natural basin that is intended for containment, treatment or
				  disposal of wastes or wastewater.
(o) "Rapid infiltration system" means a land
				  treatment system in which treatment is accomplished by the movement of large
				  quantities of wastewater through a coarse or highly permeable soil
				  profile.
(p) "Recreational unit"
				  means a tent or vehicular type structure, primarily designed as temporary
				  living quarters for recreational, camping, or travel use, that either has its
				  own motive power or is mounted on or drawn by a self-powered vehicle. A tent
				  means a collapsible shelter of canvas or other fabric stretched and sustained
				  by a rigid structure(s) and used for camping outdoors.
(q) "Seasonal high groundwater table" is the
				  highest elevation reached by the groundwater during the wet season of the year
				  (usually spring or early summer).
(r) "Sedimentation control facility" means a
				  pond or structure designed to capture runoff from disturbed areas for the
				  purpose of treating water for sediment and suspended solids removal.
(s) "Slow rate land application system" means
				  an irrigation system in which wastewater treatment is achieved due to
				  vegetative uptake and percolation of wastewater through the soil profile by low
				  application rates.
(t) "Sludge" is
				  the accumulation of solids settled from wastewater in a septic tank, aerobic
				  unit, clarifier, or equivalent.
(u)
				  "Soil" means all unconsolidated material overlaying bedrock.
(v) "Toxic characteristics (or wastes)" means
				  those characteristics (or wastes) that are due to the presence of: substances
				  or combinations of substances including disease causing agents that, after
				  discharge and upon exposure, ingestions, inhalation or assimilation into any
				  environmentally significant organism, either directly from the environment or
				  indirectly by ingestion through food chains, may cause death, disease,
				  behavioral abnormalities, cancer, genetic malfunctions, physiological
				  malfunctions (including malfunctions in reproduction) or physical deformation
				  in such organisms or their offspring. This definition shall include all
				  substances designated as toxic or hazardous by the U.S. Environmental
				  Protection Agency in the Federal Register for December 24, 1975, (Part IV),
				  Water Programs, National Interim Primary Drinking Water Regulations; Federal
				  Register for May 19, 1980, (Section 261 ), Hazardous Waste Management System:
				  Identification and Listing of Hazardous Waste; and the Federal Register for
				  July 16, 1982, Part V, National Oil and Hazardous Substances Contingency
				  Plan.
