Current through Reg. 50, No. 138; July 16, 2024
Performance-based treatment systems shall be installed in
					 compliance with the following.
(1)
				  Systems shall receive the following setbacks to the listed feature. If no
				  setback is specified for a specific feature, Part I requirements shall apply
				  unless the performance-based treatment system is located in the Florida Keys.
				  If located in the Florida Keys, Part II shall be used for all setbacks.
(a) Secondary Treatment Standards. The system
				  shall be a minimum of 65 feet from any surface water bodies or wet retention or
				  detention area if the lot was platted on or after January 1, 1972.
(b) Advanced Secondary Treatment Standards.
1. Surface water bodies: The system shall be
				  a minimum of 50 feet from any surface water bodies or wet retention or
				  detention area if the lot was platted on or after January 1, 1972.
2. Groundwater interceptor drain: 10
				  feet.
3. Dry retention area and
				  swales: 10 feet.
4. Where a
				  performance-based treatment system is placed adjacent to Class II waters,
				  setbacks that are applied to secondary treatment levels shall be applicable.
				  Alternatively, where the fecal coliform complies with the following levels,
				  reduced setbacks in subparagraphs
				   62-6.028(1)(b) 
				  1. through 3., F.A.C., above, shall be allowed.
a. System operation shall result in not more
				  than 14 fecal coliform colonies per 100 ml of effluent sample. Where chlorine
				  is used for disinfection, the design shall include provisions for rapid and
				  uniform mixing and a total chlorine residual of at least 1.0 mg/l shall be
				  maintained after at least 15 minutes contact time at the peak hourly flow. To
				  determine compliance of a system, the following operational criteria (using
				  either MF or MPN methods) are applicable.
b. The arithmetic mean of the fecal coliform
				  colonies collected during the annual period shall not exceed 14 per 100 ml of
				  effluent.
c. The median value of
				  the fecal coliform colonies for a minimum number of 10 samples of effluent,
				  each collected on a separate day during a period of 30 days (monthly) shall not
				  exceed 14 per 100 ml of sample.
d.
				  No more than 10% of the samples collected during the period of 30 consecutive
				  days shall exceed 43 fecal coliform colonies per 100 ml of sample.
e. Any one sample shall not exceed 86 fecal
				  coliform colonies per 100 ml of sample.
(c) Advanced Wastewater Treatment Standards.
1. Surface water bodies: The drainfield shall
				  be a minimum of 25' feet from any surface water bodies or wet retention or
				  detention area. The treatment unit or process containers shall be a minimum of
				  50' feet from any surface water bodies or wet retention or detention
				  area.
2. Groundwater interceptor
				  drain: 10' feet.
3. Dry retention
				  area and swales: 10' feet.
4.
				  Seasonal high water table to bottom of drainfield: 12''
				  inches.
