					 125; and as follows:
(1) "Commission"
				  means the Environmental Management Commission or its successor.
(2) "Conventional pollutants" means
				  biochemical oxygen demand (BOD(5)), Total Suspended Solids (TSS), pH, fecal
				  coliform, oil and grease, and any other pollutants the USEPA designates as
				  conventional in applicable regulations.
(3) "Director" means the Director of the
				  Division of Water Resources or Division of Energy, Mineral and Land Resources,
				  Department of Environmental Quality, whichever is the permitting authority; or
				  his or her designee.
(4) "Division"
				  means the Division of Water Resources or the Division of Energy, Mineral and
				  Land Resources, Department of Environmental Quality, whichever is the
				  permitting authority.
(5) "Effluent
				  limited" segment of a surface water means a segment that stream monitoring,
				  assessment, modeling, or other analysis indicates is meeting applicable water
				  quality standards or will meet applicable water quality standards after the
				  application of minimum treatment requirements.
(6) "Minimum treatment requirements" means
				  the minimum technology-based effluent limitations that a specific discharge
				  would be required to meet in order to satisfy applicable treatment standards,
				  including the following:
(a) "Secondary
				  treatment" is the minimum standard of treatment for POTWs, as set forth in Rule
				  .0406(a) of this Section.
(b) "Best
				  waste stabilization pond technology" is the standard of treatment for waste
				  stabilization ponds treating municipal or similar wastewaters only, as set
				  forth in Rule .0406(a) of this Section.
(c) "Best practicable waste treatment
				  technology," or "BPWTT," is an advanced standard of treatment for POTWs, as set
				  forth in Rule .0406(a) of this Section.
(d) "Best practicable pollutant control
				  technology," or "BPT," is the minimum standard of treatment for existing
				  industrial dischargers, as set forth in Rule .0406(c) of this Section and in 40
				  CFR Chapter I, Subpart N - Effluent Guidelines and Standards.
(e) "Best conventional pollutant control
				  technology," or "BCT," is a standard of treatment for existing industrial
				  dischargers and typically applies to conventional pollutants, as set forth in
				  Rule .0406(c) of this Section and in 40 CFR Chapter I, Subpart N - Effluent
				  Guidelines and Standards.
(f) "Best
				  available technology economically achievable," or "BAT" is a standard of
				  treatment for industrial dischargers and typically applies to nonconventional
				  and priority pollutants, as set forth in Rule .0406(c) of this Section and 40
				  CFR Chapter I, Subpart N - Effluent Guidelines and Standards.
(g) "New source performance standards" is the
				  standard of treatment for industrial dischargers determined to be a new source
				  pursuant to
				  15A NCAC
				  02B .0407.
Minimum treatment requirements must be met even if the
					 receiving waters affected can or are expected to be able to accept higher
					 pollutant-load levels and still meet applicable water quality standards.
