This Document Constitutes Your Permit
PART 1: PERMIT
COVERAGE
Do I need this permit for my
project?
1.1 When is this permit required?
An NPDES Stormwater construction generic permit is required for any construction
activities that:
1.1.1 Disturb one or more acres of land or disturb less than one acre of land but are
part of a common plan of development or sale
; and
1.1.2 Discharge stormwater to surface waters of the state or to surface waters of the
State through a municipal separate storm sewer system (MS4
).
You, the Responsible Authority, shall apply either for an individual permit or for coverage
under this National Pollutant Discharge Elimination System (NPDES
) Construction
Generic Permit (CGP). The Responsible Authority of a construction activity is ultimately
responsible for obtaining and complying with this permit.
1.2 What does the CGP allow me to do?
The CGP allows you to discharge surface stormwater associated with large or small
construction activity to waters of the State, either directly or through an MS4.
1.3 If I obtain the CGP, do I still need an Environmental Resource Permit (ERP)
or other permit?
Obtaining coverage under the CGP does not relieve you of the requirement to obtain an
Environmental Resource Permit (ERP
). If an ERP is required then contact the
Department, the appropriate water management district, or a delegated local program for
more information. You may also need to obtain other required permits from federal,
state, or local governments.
1.4 Do I need this permit if I am one of several contractors working at a
common site?
1.4.1 If you are a contractor or subcontractor acting under the direction of an operator
or other entity who has received coverage under the CGP for your construction
activities, you do not have to obtain your own coverage under this permit, but
must be named on the operator’s SWPPP and separately sign the SWPPP
certification (see Part 4.5
).

Effective 02/2015 1 | Page
1.4.2 If you are not named in the SWPPP or are not acting under the direction of the
responsible authority who has obtained permit coverage, you must obtain your
own permit.
1.5 Are there any limitations of coverage?
The following stormwater discharges from construction sites are not authorized by this
permit. This permit specifically does not allow you to do any of the following:
1.5.1 Cause or contribute to a violation of surface water quality standards;
1.5.2 Discharges stormwater mixed with non-stormwater, except as otherwise provided
in Part 3
of this CGP;
1.5.3 Discharge stormwater that originates from the site after construction
activities have been completed and the site has undergone final
stabilization;
1.5.4 Discharges that are mixed with sources of non-stormwater;
1.5.5 Discharges stormwater associated with construction activities that are
covered under an existing generic or individual permit. Such discharges
may be authorized under this permit after the existing generic permit or
individual permit term of coverage expires or is terminated, provided the
existing permit did not establish numeric limitations for such discharges; or
1.5.6 Discharges stormwater associated with construction activity that the
Department has determined to be or may reasonably be expected to be
causing or contributing to a violation of surface water quality standards.

3.4 Can I discharge water from groundwater dewatering operations under this
permit?
3.4.1 The CGP authorizes the discharge of uncontaminated ground water.
3.4.2 If your project site is uncontaminated, in accordance with Part 3.4.3 below, you
are authorized under the CGP to discharge uncontaminated groundwater
resulting from construction-related dewatering operations. To obtain this
authorization, you must complete Part VI of the NOI. The operator is responsible
for ensuring the groundwater is uncontaminated.
3.4.3 An uncontaminated site must meet the following conditions:
The property is either (a) not identified as a contaminated site
and there is no
identified contaminated site within 500 feet, or (b) it is identified as a
contaminated site, but DEP documentation confirms that the contamination has
been remediated or the pollutants of concern from the contaminated site are not
present in groundwater at the project site at concentrations equal to or greater
than the surface water criteria in Rule 62-302.530, F.A.C.
3.4.4 Documentation that the project site is uncontaminated must be kept at the project
site with the SWPPP.
3.4.5 Appropriate dewatering BMPs
shall be implemented to ensure that
discharges from dewatering operations do not cause or contribute to
violations of water quality standards. (See
Part 5.8.) The BMPs must be
included in the Dewatering Section of the SWPPP.
3.4.6 Discharges from dewatering operations must:
a) Not include visible floating solids or foam;
b) When feasible, discharge onto vegetated upland areas of the site
where the water can infiltrate. As an alternative, the water can be
discharged into the permitted stormwater system serving the project
site.
Note: Backwash water should be managed such that it is not discharged
directly to waters of the State. Backwash water may be hauled away for
proper disposal or returned to the beginning of the treatment process.
3.5 What if I suspect the discharge from dewatering operations are from a
contaminated site?
3.5.1 If a discharge from dewatering operations causes or contributes to a water
quality violation, the permittee shall contact the Department. This permit
only authorizes the discharge of uncontaminated groundwater. A site that
does not meet the conditions of 3.4.3 may qualify for coverage under Rule
62-621.300(1), F.A.C., or under an individual wastewater permit on the
appropriate form listed in Rule 62-620.910, F.A.C.
3.5.2 Coverage under this permit may be suspended, revoked and reissued, or
terminated in accordance with Rule 62-620.345, F.A.C., if the Department
determines that there has been a violation of any of the terms or conditions
of the permit, there has been a violation of state water quality standards or
the permittee has submitted false, incomplete or inaccurate data or
information.

EST MANAGEMENT
PRACTICES (BMPs)
What BMPs apply to my
project?
5.1 What BMPs am I required to use on my project?
Construction activities must not cause or contribute to a water quality violation or offsite
sedimentation. You are encouraged to phase your construction activities to avoid
potential water quality violations. BMPs must be installed before the commencement of
your construction activities.
All BMPs must be consistent with the guidelines contained in the State of Florida Erosion
and Sediment Control Designer and Reviewer Manual, FDOT and FDEP (2013)
http://www.stormwater.ucf.edu/publications/2013RevisedDesignerManual.pdf, or from
http://www.flrules.org/Gateway/reference.asp?No=Ref-04227

controls, erosion and sediment controls, stabilization practices, and structural
controls. All BMPs must be described in your SWPPP.
5.1.8 Dewatering BMPs must be maintained throughout the duration of dewatering
operations.
5.1.9 Temporary perimeter controls must be removed after final stabilization.
5.2 What pollution prevention control BMPs must be implemented?
You must, at a minimum, install, implement, and maintain pollution prevention control
BMPs that accomplish all of the following:
5.2.1 Minimize the discharge of pollutants from equipment and vehicle washing, wheel
wash water, and other wash waters that are covered under this permit so as to
not cause a violation of water quality standards or offsite sedimentation.
5.2.2 Minimize the exposure of building materials, building products, construction
wastes, trash, landscape materials, fertilizers, pesticides, herbicides, detergents,
sanitary waste, toxic substances, and other materials present on the site to rain
and to stormwater that may run onto or across your site so as to not cause or
contribute to a violation of water quality standards.
5.2.3 Minimize the discharge of pollutants from spills and leaks. Your SWPPP must
include and you must implement chemical spill and leak prevention and response
procedures.
5.3 What erosion and sediment control BMPs apply?
You must, at a minimum, install, implement, and maintain appropriate erosion and
sediment controls that accomplish all of the following so as to not cause or contribute to
a violation of water quality standards and minimize offsite sedimentation:
5.3.1 Control stormwater volume and velocity within the site to minimize soil erosion
and offsite sedimentation.
5.3.2 Control stormwater peak discharge rates and volume to minimize erosion at
discharge outfalls and to minimize downstream channel and stream bank
erosion.
5.3.3 Minimize the amount of soil exposed during the construction activity.
5.3.4 Minimize the disturbance of steep slopes.
5.3.5 Minimize sediment discharges from the site.
5.3.6 Minimize off-site vehicle tracking of sediments onto paved surfaces and the
generation of dust so as to prevent the potential for water quality violations and
offsite sedimentation. If sediment escapes the construction site, remove off-site
accumulations of sediment at a frequency sufficient to minimize off-site impacts.
5.3.7 In selecting your sediment and erosion controls, you must consider factors such
as the amount, frequency, intensity, and duration of precipitation; the
characteristics of the resulting stormwater; and the site’s soil characteristics,
including the range of soil particle sizes expected to be present on the site.
5.4 Do I have to use Stabilization Measures?
You must initiate stabilization measures within 7 calendar days after construction
activities have temporarily or permanently ceased for any portion of the site.
Stabilization
measures include:
Temporary seeding.
Permanent seeding.
Mulching.

Sod stabilization.
Vegetative buffer strips.
Protection of trees.
Preservation of mature vegetation.
Other appropriate measures.
DEP Document No. 62-621.300(4)(a)
Effective 02/2015 11 | Page
5.4.1 You must include in your SWPPP, and update when necessary, the dates when
major grading activities occur, when construction activities temporarily or
permanently cease on a portion of the site, and when stabilization measures are
initiated.
5.4.2 You must achieve Final Stabilization prior to filing a Notice of Termination in
accordance with Part 7.1
or the expiration of coverage under this, or a
subsequent, generic permit.
5.5 Do I have to use Structural Practices?
You must use controls to accomplish the following:
5.5.1 As necessary to prevent violations of water quality or offsite sedimentation, you
must divert flows from exposed soils, store flows, retain sediment on site, or
otherwise limit runoff and the discharge of pollutants from exposed areas of the
site.
5.5.2 Structural practices to prevent violations of water quality or offsite sedimentation,
which may include the following: silt fences, earth dikes, diversions, swales,
sediment traps, check dams, subsurface drains, pipe slope drains, level
spreaders, storm drain inlet protection, rock outlet protection, reinforced soil
retaining systems, gabions, coagulating agents, and temporary or permanent
sediment basins.
5.5.3 Silt fences or equivalent structural controls are required for all side slope and
down slope boundaries of the construction area.
5.5.4 Structural best management practices must be placed on upland soils unless a
State of Florida environmental resource permit
issued pursuant to Chapter 373,
F.S., or applicable regulations of the DEP or WMD otherwise authorize.
5.6 What requirements apply to sediment basins?
If you have 10 or more disturbed acres on your site, the following design requirements
shall be met:
For drainage basins with 10 or more disturbed acres at one time, a
temporary (or permanent) sediment or wet detention basin providing
3,600 cubic feet of storage per acre drained must be provided until final
stabilization of the site. The 3,600 cubic feet of storage area per acre
drained does not apply to flows from off-site areas and flows from on-
site areas that are either undisturbed or have undergone final
stabilization where such flows are diverted around both the disturbed
area and the sediment basin.
For drainage basins with 10 or more disturbed acres at one time and
where a temporary sediment basin providing 3,600 cubic feet of storage
per acre drained is not attainable, a combination of smaller sediment
basins, sediment traps, wet detention systems, or other best
management practices must be used.
5.6.1 For drainage basins of less than 10 disturbed acres, sediment basins and
sediment traps are recommended but not required.
5.6.2 Areas that will be used for permanent stormwater infiltration treatment (e.g.,
stormwater retention basins) should not be used for temporary sediment basins
unless appropriate measures are taken to assure removal of accumulated fine
sediments, to avoid excessive compaction of soils by construction machinery or
equipment, and to assure that the design infiltration capacity is met.
5.7 What requirements apply to permanent stormwater management controls?
Your SWPPP must include a description of stormwater management controls or BMPs
(e.g., stormwater detention or retention systems, vegetated swales, or velocity
dissipation devices at discharge points) that will be installed during the construction
process to control pollutants in stormwater discharges that will occur during construction
and after construction operations have been completed.
Under this CGP, you are only responsible for the installation and maintenance of
stormwater management controls until the construction activities have been completed
and the site has undergone final stabilization. However, all stormwater management
systems and BMPs must be operated and maintained in perpetuity after final
stabilization in accordance with requirements set forth in the State of Florida
environmental resource permit
issued under Part IV, Chapter 373, F.S.
5.8 What Dewatering BMPs can I use?
The operator shall develop and implement site specific control measures or BMPs to
minimize or eliminate pollutant discharges resulting from dewatering operations to
surface waters of the state. Appropriate BMPs shall have been developed and
implemented upon commencement of the discharge. The most common BMPs for
treating dewatering discharges include sediment traps and basins, weir and dewatering
tanks, filters, and chemical treatment. These technologies and approaches provide a
number of options to achieve sediment removal. The sizes of the particle that make up
the sediments are a key consideration in selecting sediment control options.
