Terms used in this chapter shall have the meanings
					 specified below.
(1) "Ammonia nitrogen
				  (NH3-N)" means the quantity of elemental nitrogen present in water or
				  wastewater as ammonia (NH3), expressed as elemental
				  nitrogen, N, as determined using approved methods.
(2) "Annual average daily flow (AADF)" means
				  the arithmetic mean of the 12 monthly average daily flows calculated during any
				  consecutive 12-month period, expressed in units of mgd.
(3) "Aquifer" means a geologic formation,
				  group of formations, or part of a formation capable of yielding a significant
				  amount of ground water to wells, springs, or surface water.
(4) "Approved methods" means sampling and
				  laboratory testing methods conducted in accordance with Rule
				   62-4.246, Part IV of this
				  chapter; Chapter 62-160, and paragraph
				   62-620.100(3)(j),
				  F.A.C., as appropriate.
(5)
				  "Arithmetic mean" means the value computed by dividing the sum of a set of
				  terms by the number of terms.
(6)
				  "Average daily flow (ADF)" means the total volume of wastewater flowing into a
				  wastewater facility during some defined period of time, divided by the number
				  of days in that period of time, expressed in units of mgd.
(7) "Biosolids" means the solid, semisolid,
				  or liquid residue generated during the treatment of domestic wastewater as
				  defined in Chapter 62-640, F.A.C. Not included is the treated effluent or
				  reclaimed water from a domestic wastewater treatment plant.
(8) "Carbonaceous biochemical oxygen demand
				  (CBOD5)" means the quantity of oxygen utilized in the carbonaceous biochemical
				  oxidation of organic matter present in water or wastewater, reported as a
				  five-day value determined using approved methods.
(9) "Chloride" means the negatively charged
				  chloride ion (Cl
-
) in water or wastewater, as determined using
				  approved methods.
(10) "Coastal
				  recreation waters" means those waters defined in
				  40 C.F.R.
				  131.41(b).
(11) "Coastal waters" means all estuarine,
				  gulf, or ocean waters which are not classified as open ocean waters.
(12) "Collection/transmission systems" means
				  sewers, pipelines, conduits, pumping stations, force mains, and all other
				  facilities used for collection and transmission of wastewater from individual
				  service connections to facilities intended for the purpose of providing
				  treatment prior to release to the environment.
(13) "Composite sample" means a single sample
				  that is a combination of individual sub-samples of wastewater, effluent, or
				  reclaimed water taken at selected intervals, usually based on time or flow
				  volumes, to minimize the effect of the variability of the individual
				  sub-samples.
(14) "Department"
				  means the State of Florida Department of Environmental Protection.
(15) "DOH" means the State of Florida
				  Department of Health.
(16) "Design
				  capacity" means the average daily flow projected for the design year which
				  serves as the basis for the sizing and design of the wastewater facilities. The
				  design capacity is established by the permit applicant. The time frame
				  associated with the design capacity (e.g., annual average daily flow, monthly
				  average daily flow, three-month average daily flow) shall be specified by the
				  permit applicant.
(17) "Developed
				  areas" means areas in or adjacent to residential, commercial, or residentially
				  or commercially-zoned areas.
(18)
				  "Disinfection" means the selective destruction of pathogens in wastewater
				  effluents, reclaimed water, and biosolids.
(19) "Disposal system" means injection wells,
				  effluent outfalls, land application systems, and other facilities utilized for
				  the release of effluents into the environment.
(20) "District office" means the regional
				  district offices of the Department.
(21) "Domestic wastewater" means wastewater
				  derived principally from dwellings, business buildings, institutions, and the
				  like, commonly referred to as sanitary wastewater or sewage. Where industrial
				  wastewater is combined with domestic wastewater for treatment, the
				  determination of whether or not the wastewater treatment plant is designated as
				  "domestic" shall be made by the Department considering any or all of the
				  following: biosolids classification; whether wastewaters have been pretreated
				  or contain constituents within 50-150%, by concentration, of typical domestic
				  wastewater; and whether the permittee, when not required to provide more
				  stringent or otherwise specific levels of treatment, can provide assurance of
				  facility compliance with domestic wastewater treatment standards contained in
				  this chapter.
(22) "Effluent, "
				  unless specifically stated otherwise, means water that is not reused after
				  flowing out of any plant or other works used for the purpose of treating,
				  stabilizing, or holding wastes.
(23) "Effluent limitation" means the same as
				  defined in Section  403.031(3),
				  F.S.
(24) "Fecal coliforms" means
				  members of the coliform group capable of producing gas from lactose at
				  44.5º C, as determined using approved methods.
(25) "Flow" shall mean the following:
(a) For wastewater facilities having a
				  permitted capacity of 100, 000 gallons per day or greater, flow values obtained
				  from recording flow meters and totalizers, calibrated at least once every 12
				  months; and,
(b) For wastewater
				  facilities having a permitted capacity of less than 100, 000 gallons per day,
				  flow values obtained by one of the following methods:
1. Elapsed time measurements on pumps where
				  pumps are responsible for the flow and where the pumping rate is calibrated at
				  least once every 12 months,
2.
				  Consumptive water use measurements based upon written approval by the
				  Department where elapsed time measurement on pumps cannot be made,
3. Flow meters and weirs, calibrated at least
				  once every 12 months, or
4. Other
				  means using established engineering techniques.
