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).

DEP Document No. 62-621.300(4)(a) Effective 02/2015 1 | P a g e

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.

http://www.flrules.org/Gateway/reference.asp?No=Ref-04227

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.

• Geotextiles.

• Sod stabilization.

• Vegetative buffer strips.

• Protection of trees.

• Preservation of mature vegetation.

• Other appropriate measures.

Effective 02/2015 11 | P a g e

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.

PART 6: INSPECTIONS

How should I inspect my project?

6.1 When must I inspect my site? By whom?

Your site must be inspected at least once every seven calendar days and within 24 hours of the end of a storm event that is 0.50 inches or greater (even if it rains on the weekend or a holiday). Your site must be inspected by a qualified inspector that you must provide.

6.2 What must your inspection cover?

Your qualified inspector must:

6.2.1 Inspect all stormwater discharges from the site to ensure BMPs are not causing or contributing to violations of water quality standards or resulting in offsite sedimentation. http://www.dep.state.fl.us/water/wqssp/classes.htm

6.2.2 Inspect the BMPs identified in the SWPPP to ensure that they are installed, maintained, and operating correctly and effectively.

6.2.3 Inspect all areas used for storage of materials that are exposed to rainfall and runoff to ensure all BMPs are being used and maintained properly.

6.2.4 Inspect all locations where vehicles enter or exit the site for evidence of offsite sediment tracking and inform operator of all actions needing to be taken to remove sediments on the road and prevent it in the future.

6.2.5 Inspect all distributed areas and discharge points for signs of visible erosion and sedimentation.

6.3 What information must be included in the inspection report?

The report must contain all of the following:

6.3.1 Scope of the inspection.

6.3.2 Name(s) and qualifications of personnel making the inspection.

6.3.3 Date(s) of the inspection.

6.3.4 Rainfall data.

6.3.5 Major observations relating to the implementation of the SWPPP.

6.3.6 Corrective actions taken since last inspection in accordance with Part 6.4.

6.3.7 Any incidents of non-compliance. (Where an inspection does not identify any incidents of non-compliance, the report must certify that the facility is in compliance with the SWPPP and the CGP.)

6.3.8 Signature of the qualified inspector that prepared the report. (See Part 9.1, below.)

6.3.9 Signature of a responsible authority. (See Part 9.1, below.)

6.4 If the inspection identifies needed corrective actions, when must they be accomplished?

Based on the results of the inspection, all corrective actions needed to assure proper operation of all controls identified in your SWPPP or to ensure that the requirements of the permit are met must be done in a timely manner, but in no case later than 7 calendar days following the inspection or identification of the issue. If needed, you must revise your SWPPP and modify your controls in a timely manner, but in no case later than 7 calendar days following the inspection or identification of the issue. (See Part 4.4)

6.5 Can I temporarily suspend the weekly/0.5 inch inspections?

6.5.1 Once you have achieved final stabilization, you may suspend inspections.

6.5.2 You may reduce the frequency of inspections to once per month on your site if you:

6.5.2.1 Have achieved temporary stabilization that is successful at stabilizing the site for the duration of your suspended construction activities; and

6.5.2.2 Have your SWPPP updated as to why you are suspending construction activities at your site and have met the conditions of 6.5.1. The SWPPP must include:

a. The status and type of stabilization implemented,

b. The date the activities were suspended, and

c. The anticipated date activities will resume.

6.5.3 If construction activity resumes in this portion of the site at a later date, the inspection frequency immediately returns to the frequency required by this permit under Part 6.1. You are at all times responsible for ensuring that your temporary stabilization methods are in compliance with permit conditions.

6.5.4 If at any time after you suspend construction activities you determine the site will not resume activities during the term of your permit coverage, you must achieve Final Stabilization and file a Notice of Termination. During that intermediate period of time all terms of this permit will apply.

Effective 02/2015 15 | P a g e

PART 7: COMPLETION =

NOTICE OF TERMINATION

(NOT)

What should I do when my project is complete?

7.1 What must I do when my project is complete or I no longer need the permit coverage?

Within 14 calendar days after your site has achieved final stabilization and all discharges authorized by this permit are eliminated or are authorized under a separate NPDES permit, you must submit a completed Notice of Termination (NOT) form.

7.1.1 All dewatering discharges authorized by this permit have ceased.

7.1.2 All construction activity discharges authorized by this permit have ceased.

Elimination of stormwater discharges associated with construction activity means that all disturbed soils at the site have been final stabilized, that temporary erosion and sediment control measures have been removed or will be removed at an appropriate time, and that all stormwater discharges associated with construction activity from the site that are authorized by the CGP have been eliminated.

7.2 Can I transfer the CGP following a sale or transfer of project operation?

Coverage under the CGP is not transferable. The new owner/operator will need to complete a SWPPP and submit a new NOI and processing fee. You need to end the current permit coverage by submitting a Notice of Termination (NOT) within 14 calendar days of relinquishing control of the project to a new owner/operator. It is the responsibility of the new owner/operator to obtain coverage before the NOT is submitted.

7.3 How do I submit my NOT?

7.3.1 You can submit the form electronically: To file your NOT online go to:

http://www.fldepportal.com/go/

7.3.2 Alternatively you can submit a NOT by email to the Notices Center: To download the NOT go to:

http://www.dep.state.fl.us/water/stormwater/npdes/permits_forms.htm

For additional assistance please contact the Notice Center at: (866) 336-6312 (toll-free).

7.4 Who can sign the NOT?

The responsible authority must sign the NOI unless the responsible authority designates a duly authorized representative who may sign on the responsible authority’s behalf.

7.5 What happens after I submit my NOT?

The Department will send you an acknowledgment letter by email. If your project discharged stormwater to a permitted MS4, you must send a copy of the NOT or the acknowledgement letter within 7 calendar days of receipt to the operator of the MS4.
