Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-6 - STANDARDS FOR ONSITE SEWAGE TREATMENT AND DISPOSAL SYSTEMS › Part IV - Performance-based Treatment Systems › Section 62-6.025 - Definitions

Current through Reg. 50, No. 138; July 16, 2024
Definitions in Chapter 62-6, Parts I and II, F.A.C., are
					 also applicable to Chapter 62-6, Part IV, F.A.C.
(1) Composite sample - a defined mixture of
				  grab samples of wastewater or effluent taken in proportion to either time or
				  flow.
(2) Disposal component -
				  arrangement of equipment and/or materials that distributes effluent within a
				  drainfield.
(3) Effluent - the
				  recovered water product from a sampling point following the final design
				  treatment step.
(4) Failure - as in
				  subsection  62-6.002(23),
				  F.A.C., including non-compliance with applicable treatment performance
				  standards as defined in paragraph
				   62-6.025(11)(e),
				  F.A.C., unless the maintenance entity performs and documents maintenance after
				  a sampling event, undertakes a second sampling event within 30 days of the
				  first, and the results of which meet the applicable treatment performance
				  standard.
(5) Grab sample - a
				  sample which is taken from wastewater or effluent over a period of time not to
				  exceed fifteen minutes.
(6)
				  Effective storage volume - fillable volume in the drainfield material within
				  the vertical distance from the bottom of the drainfield to the invert of the
				  distribution pipe.
(7)
				  Performance-based treatment system - a specialized onsite sewage treatment and
				  disposal system designed by a professional engineer with a background in
				  wastewater engineering, licensed in the state of Florida, using appropriate
				  application of sound engineering principles to achieve specified levels of
				  CBOD5 (carbonaceous biochemical oxygen demand after five
				  days), TSS (total suspended solids), TN (total nitrogen), TP (total
				  phosphorus), or fecal coliform found in domestic or commercial sewage waste, to
				  a specific and measurable established performance standard.
(a) Treatment components which have already
				  been approved as meeting the requirements of subsection
				   62-6.012(1),
				  F.A.C., are not required to obtain an Innovative System Permit to be approved
				  as a component of a performance-based treatment system. The manufacturer must
				  request such approval from the Onsite Sewage Program in writing. When proposed
				  as part of a performance-based treatment system, the treatment component's
				  proposed performance must not exceed the following:
1. For CBOD5 and TSS, the average effluent
				  concentration as reported by the applicable NSF 40 standard testing completion
				  report, or corresponding results of an NSF 245 or NSF 350 testing completion
				  report.
2. For TN, the average
				  performance expressed as percent removal reported in the applicable NSF 245
				  standard testing completion report.
3. For fecal coliform, the performance
				  expressed as percent removal for E. coli based on average influent and effluent
				  concentrations reported in the applicable NSF 350 testing completion
				  report.
