Current through June 24, 2024
In addition to the definitions and abbreviations in ss.
					 NR
					 205.03 and
					 205.04, the following definitions are
					 applicable to terms used in this subchapter:
(1) "Baseline load" means the reference load
				  used in distributing all or part of the total maximum load among multiple point
				  source dischargers to a water quality limited segment.
(2) "Categorical effluent limitation" means a
				  point source effluent limitation for categories and classes of point sources
				  other than publicly-owned treatment works achieved by application of the best
				  practicable control technology currently available, the best conventional
				  pollutant control technology, or the best available technology economically
				  achievable as required by s.
				  283.13(2),
				  Stats.; or means a point source effluent limitation for a publicly-owned
				  treatment works achieved by application of secondary treatment as required by
				  s.
				  283.13(4),
				  Stats.
(3) "Conventional pollutant"
				  means those pollutants identified in section 304 (a) (4) of the federal clean
				  water act amendments of 1977. These pollutants are: biochemical oxygen demand
				  (BOD), total suspended solids (TSS), pH, fecal coliform, and oil and
				  grease.
(4) "Cost-effective
				  analysis" means a systematic comparison of alternative means of meeting state
				  water quality standards, effluent limitations or other treatment standards in
				  order to identify the alternative which will minimize the total resources costs
				  over the appropriate planning period. These resources costs include monetary
				  costs and environmental as well as other nonmonetary costs.
(5) "Critical water quality conditions" means
				  those water conditions upon which are based the most stringent water quality
				  effluent limitations.
(5m)
				  "Designated management agency" means any agency designated in an areawide water
				  quality management plan having responsibility for implementing specific plan
				  recommendations.
(6) "Effluent
				  limitation" whenever used without qualification means any restriction including
				  schedules of compliance, established by the department, on quantities, rates
				  and concentrations of chemical, physical, biological, and other constituents
				  which are discharged from point sources into waters of this state.
(7) "Flow reregulation" means any practice
				  with respect to the available surface waters in a basin that would alter the
				  stream flows from those which would occur under existing regimes.
(8) "Infiltration" means water other than
				  waste water that enters a sewerage system, including sewer service connections,
				  from the ground through such sources as defective pipes, pipe joints,
				  connections, or manholes. Infiltration does not include, and is distinguished
				  from, inflow.
(9) "Inflow" means
				  water other than waste water that enters a sewerage system, including sewer
				  service connections, from sources such as roof leaders, cellar drains, yard
				  drains, area drains, foundation drains, drains from springs and swampy areas,
				  manhole covers, cross connections between storm sewers and sanitary sewers,
				  catch basins, cooling towers, storm waters, surface runoff, street wash waters,
				  or drainage. Inflow does not include, and is distinguished from,
				  infiltration.
(10) "Instream
				  aeration" means techniques which increase the dissolved oxygen content of a
				  receiving water. Those techniques include, but are not limited to, mechanical
				  aeration devices, diffuser systems, and turbine venting.
(11) "Margin of safety" means a portion of
				  the total maximum load which accounts for the uncertainties concerning the
				  relationship between effluent limitations and water quality or provide a
				  greater assurance that the water quality standards will be met. This portion of
				  the total maximum load is not available for allocation to point
				  sources.
(12) "New point source",
				  for the purposes of this subchapter, means a point source which commenced
				  operation after January 1, 1980.
(13) "Nonpoint source" means a source of
				  pollution resulting from a land management activity which contributes to
				  runoff, seepage or percolation; and which is not defined as a point
				  source.
(14) "Nonpoint source
				  allocation" means that portion of the total maximum load distributed or
				  apportioned to nonpoint sources and unavailable for allocation to point
				  sources.
(14e) "Off-machine
				  production" means that quantity of paper or paperboard taken from a paper
				  machine for further processing, conversion or sale exclusive of coating
				  material applied after the paper machine.
(14q) "Projected population change" means an
				  increment of projected population change for a sewer service area pursuant to
				  the appropriate areawide water quality management plan.
(15) "Point source allocation" means that
				  portion of the total maximum load distributed or apportioned to point
				  sources.
(16) "Publicly-owned point
				  source" means any point source which is owned by a municipality.
(17) "Public sector growth" means an increase
				  in waste water discharge from any person except industrial establishments,
				  whose waste water is treated by a publicly-owned point source.
(18) "Reserve capacity" means that portion of
				  the total maximum load reserved for allocation to new or expanding point
				  sources.
(19) "Residential growth"
				  means an increase in population.
(20) "Stream segment" means a portion of a
				  stream including natural and artificial flowages.
(21) "Total maximum load" means the maximum
				  quantity of a pollutant or pollutants that can be discharged into a water
				  quality limited segment over a specified period of time to maintain the
				  applicable water quality standards. The total maximum load is the sum of the
				  point source allocation, the nonpoint source allocation, the reserve capacity
				  and the margin of safety.
(22)
				  "Wasteload allocation" means the allocation resulting from the process of
				  distributing or apportioning the total maximum load to each individual point
				  source discharge.
(23) "Water
				  quality limited segment" means any area or portion of a stream which will not
				  meet the established water quality standard with application of only
				  categorical effluent limitations to all point sources.
(24) "Water quality related effluent
				  limitation" means a point source effluent limitation designed to meet
				  applicable water quality standards and which is more restrictive than the
				  categorical effluent limitations. For the purposes of this subchapter, water
				  quality related effluent limitations refer to those determined as a result of a
				  wasteload allocation.
(25) "Water
				  quality standards" means administrative rules adopted as chs.
				  NR 102,
				  103 and
				  104, under authority of s.
				  281.15,
				  Stats.
(26) "WPDES permit" means a
				  Wisconsin pollutant discharge elimination system permit for the discharge of
				  pollutants issued by the department under ch. 283, Stats.
