Definitions in Chapter 62-6, Parts I and III, F.A.C., are
also applicable to Chapter 62-6, Part II, F.A.C.
(1) Building Area - that enclosed area of a
dwelling unit, excluding the garage, carport, exterior storage shed, or open or
screened patios or decks. Calculations of building area shall be made by
measurements of the outside building dimensions. Building area of each
additional story of the structure shall be added to determine the total
building area.
(2) Cesspit - a pit,
with or without a cover, that receives untreated sewage from a building and
discharges the sewage, either untreated or improperly treated, directly to the
surrounding soil or limestone. A septic tank that functions as a cesspit shall
be considered a cesspit.
(3)
Injection well - an open vertical hole at least 90 feet in depth, fully cased
and grouted to at least 60 feet in depth which is used to dispose of onsite
sewage treatment and disposal system effluent.
(4) Minimum level of waste treatment - a
treatment which will provide a recovered water product that contains not more,
on a permitted annual average basis, than the following concentrations from a
sampling point located following the final design treatment step of the onsite
sewage treatment and disposal system:
|
(a) Biochemical Oxygen Demand
(CBOD5)
|
10 mg/1
|
|
(b) Suspended Solids
|
10 mg/1
|
|
(c) Total Nitrogen, expressed as N
|
10 mg/1
|
|
(d) Total Phosphorus, expressed as P
|
1 mg/1
|
(5)
Salt Marsh and Buttonwood Associations - two plant associations that are
sometimes collectively or individually referred to as the "transitional zone."
(a) The salt marsh community is a wetland
area subject to tidal influence wherein the dominant vegetation includes the
following:
1.
Batis maritima
Saltwort,
2.
Distichilis
spicata Salt grass,
3.
Fimbristylis castanea Chestnut sedge,
4.
Monanthochloe littoralis
Key grass,
5.
Salicornia
spp. Glasswort,
6.
Sesuvium portulacastrum Sea purslane; and,
7.
Spartina spp. Cordgrass.
The woody vegetation that may be present includes red,
white and black mangroves, as well as buttonwood (Conocarpus
erectus); the salt marsh community is distinguished by the dominance
of non-woody plants, and the woody species have a coverage of less than 40
percent. The salt marsh community may be associated and intermixed with areas
of almost bare ground on which the vegetation may be limited to mats of
algae.
(b) The
buttonwood association is an association that is usually present in the more
landward zone, and may intermix with more upland communities. The vegetation
may include, but is not limited to, the following species:
1.
Borrichia spp. Sea oxeye
daisy,
2.
Bumelia
celastrina Saffron plum,
3.
Coccoloba uvifera Sea
grape,
4.
Conocarpus
erectus Buttonwood,
5.
Erithalis fruticosa Black torch,
6.
Fimbristylis castanea
Chestnut sedge,
7.
Jacquinia keyensis Joewood,
8.
Lycium carolinianum
Christmas berry,
9.
Maytenus phyllanthoides Mayten; and,
10.
Spartina spp. Cordgrass.
The buttonwood association is distinguished from the salt
marsh association by the dominance of buttonwood trees, usually occurring as an
open stand that permits the growth of an under-story of groundcovers and
shrubs.
(6) Nutrient reducing material - material
which is used in the final treatment stage of an onsite sewage treatment and
disposal system to reduce effluent nutrient levels to the minimum level of
waste treatment.
(7) Undocumented
system - an onsite sewage treatment and disposal system that does not have a
record of installation and approval.
