Florida Administrative Code › 62 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 62 - Departmental › Chapter 62-6 - STANDARDS FOR ONSITE SEWAGE TREATMENT AND DISPOSAL SYSTEMS › Part II - Florida Keys › Section 62-6.018 - System Location, Design and Maintenance Criteria

Current through Reg. 50, No. 138; July 16, 2024
Table III of Chapter 62-6, Part I, F.A.C., and other
					 subsections of Part I pertaining to soil texture, soil depth, and maximum
					 sewage loading rates for specific soils shall not apply to areas subject to the
					 provisions of this part except for Table III, Footnote 2., as it relates to the
					 falling head percolation test procedure. However, approved system design
					 criteria, system location, operation, maintenance and monitoring requirements
					 of subsections  62-6.018(1), (2), (3), and
					 (4), F.A.C., shall apply. A minimum of one
					 soil profile and one percolation test per application shall be required for
					 site evaluations performed in the Florida Keys. However, a soil profile and
					 percolation test is not required when the system design engineer chooses the
					 use of an injection well for effluent disposal. All new onsite sewage treatment
					 and disposal systems shall be performance-based treatment systems designed by
					 an engineer licensed in the State of Florida and shall meet the minimum level
					 of waste treatment as defined in Rule
					  62-6.017, F.A.C. All receptacles
					 subject to a positive buoyancy exposure shall be anchored or otherwise weighted
					 to prevent flotation during flooding periods. The receptacles shall be
					 evaluated for buoyancy while in their normal operating condition.
(1) An onsite sewage treatment and disposal
				  system which meets the location, construction, maintenance and operational
				  requirements of paragraph
				   62-6.018(1)(a) or
				  (b), F.A.C., shall be approved, provided that
				  if an aerobic treatment unit is a component of the system design, the
				  certification, construction, operational and maintenance requirements of Rule
				   62-6.012, F.A.C., shall also be
				  met.
(a) When final effluent disposal is into
				  a nutrient reducing material-lined drainfield system, the following general
				  requirements shall apply:
1. The Department
				  shall require the installer of a nutrient reducing material lined drainfield
				  system to provide certification from the installer's nutrient reducing material
				  supplier that the material supplied for such type of installations meets the
				  requirements of this subsection.
2.
				  No part of the system shall be within 25' feet of the boundaries of surface
				  water bodies or salt marsh and Buttonwood Association habitat areas where the
				  dominant vegetation species are those typical of salt marsh
				  communities.
3. The bottom surface
				  of the nutrient reducing material layer shall be at least 12'' inches above
				  mean high water.
4. Appropriate
				  shallow root vegetative cover shall be established over drainfield systems to
				  maximize the beneficial effects of evapotranspiration.
5. Nutrient reducing material has a finite
				  life span. The nutrient reducing material shall be replaced as necessary to
				  ensure that the system continues to meet the minimum level of waste
				  treatment.
