Obtaining an N.P.D.E.S. Permit

Are you doing construction or demolition that will be disturbing 0.5 acres (21,780 square feet) or more of total land area? If so, a City of Miami N.P.D.E.S. (National Pollutant Discharge Elimination System) permit is required for compliance with Florida Statutes. All methods of construction shall comply with all applicable federal, state, and local laws as required by the City of Miami’s MS4 (Municipal Separate Storm Sewer System) and City Ordinance 13081.

NOTE: If you will be applying for a Building permit, you must get your N.P.D.E.S permit first. If the construction is taking place in the right-of-way (and is more than 0.5 acres), you must get the N.P.D.E.S permit first, before getting your right-of-way permit from iPW (the electronic plan review for right-of-way permitting). 

Steps

Collect Documents

The documents you need are determined by the total size of your project. Please see below and follow accordingly. 

A. If your project is disturbing 0.5 acres to 1.0 acres (21,780 to 43,560 square feet), you need the following:

  • Two (2) complete signed and sealed Stormwater Pollution Prevention Plans (SWPPP) that comply with the most recent versions of the FDEP/FDOT Erosion and Sediment Control Designer and Reviewer Manual and/or the Florida Stormwater, Erosion, and Sedimentation Control Inspector’s Manual, and Public Works Standards.
  • $395 permit review fee to the City of Miami.  Payment may be submitted with a check or money order payable to the City of Miami along with required documents.

B. If your project is disturbing more than one (1) acre (43,560 square feet or more), you will need the following items:

  • Two (2) complete signed and sealed Stormwater Pollution Prevention Plans (SWPPP) that comply with the most recent versions of the FDEP/FDOT Erosion and Sediment Control Designer and Reviewer Manual and/or the Florida Stormwater, Erosion, and Sedimentation Control Inspector’s Manual, and Public Works Standards.
  • $395 permit review fee to the City of Miami. You will need to pay with a check or money order payable to The City of Miami when you turn in your documents. Payment may be submitted with a check or money order payable to the City of Miami along with required documents. State fees may vary depending on total acreage.
  • FDEP Permit Letter of Permit Coverage with the corresponding FLR#. FDEP charges an additional permit fee. In order to obtain the FDEP permit, a notice of intent (NOI) must be submitted to FDEP. For more information, please contact State of Florida Department of Environmental Protection

Submit Documents & Pay Review Fee

You must submit the above documents as well as the permit review fee of $395 N.P.D.E.S Section in the Department of Resilience and Public Works located at: 

444 SW 2nd Ave, 8th Floor
Miami, FL, 33130

You will then be given your permit in-person. N.P.D.E.S section will notify the Building Department and iPW that this requirement has been satisfied, and you can now apply for your Building/iPW permit. 

Schedule N.P.D.E.S Inspection(s)

  • After receiving your Building or iPW permit, but before you begin any construction or demolition, your project contractor needs to contact the N.P.D.E.S Section at (305) 416-1295 for the initial erosion and sediment control inspection of the construction site. The initial inspection will consist of making sure that the best management practices in the approved SWPPP are in place and all the storm sewer inlets in the vicinity of the construction area are protected and free of debris.
  • The City Inspector will be conducting a thorough inspection of the construction site on a weekly basis or after ¾” rain storm event. A copy of the inspection report is available for review in the Department of Resilience and Public Works.
  • For a final inspection, you must arrange to have a vactor truck company come to the site to clean the storm sewer systems in the vicinity of the construction site in the presence of a N.P.D.E.S. Inspector. You should call to set up a final inspection with the N.P.D.E.S. Inspector or by calling 305-415-1295. Not following best management practices can place a hold on obtaining a Certificate of Occupancy and create unnecessary cost (violation fees) to the Contractor. 

Q: I have to pump water away from part or all of my site because I have standing water onsite and I need to work in a dry condition. Do I need a permit?

Yes.

Q: I already have a stormwater permit from DERM. Do I need the City approval too?

Yes. What you received from DERM was an Environmental Resource Permit (ERP) which is necessary for the construction of stormwater management and conveyance systems. The City of Miami NPDES approval is a different process. If it satisfies the City’s requirements, you may be able to submit the SWPPP developed for the ERP to the City as part of the NPDES approval

Q: I’ll be pouring concrete as part of my project. Can I use the storm drains to drain the water that is used to rinse off the concrete trucks?

NO! Excess concrete and concrete washwater can only be disposed into approved watertight concrete washout areas. These areas should be clearly shown on the SWPPP with a detail included. Concrete washwater and wet concrete are caustic and must be treated as hazardous waste. It should never be washed or placed in storm drains or on the public right-of-way.

Q: I am a contractor working on a City of Miami or School Board or FDOT or Miami-Dade County or a Ffederal funded project. I’m exempt from these requirements?

No. The NPDES approval process applies to all entities working within City of Miami limits, without exception, including public agencies and utilities.

Q: I implemented all the measures listed in my approved SWPPP but there are still erosion and sediment problems on my site. I’m still in compliance, right?

No. The State of Florida and City of Miami NPDES laws are performance-based. This means that your erosion and sediment control measures have to work in order for the site to be in compliance. If they don’t work, the Operator is responsible for strengthening or changing the practices so that they do work. All such changes must be recorded in the SWPPP kept onsite and are subject to Public Works NPDES Section approval.

Q: How can I be in compliance/what mistakes should I avoid? 

  • Dirt or other Pollution entering the City of Miami affects the Storm Sewer System. You must protect all the storm water systems as indicated in the initial inspection and the approved SWPPP.
  • Dewatering turbid excavated water (no more than > 29 NTU) in the public right of way.
  • Do not start clearing and grading, demolition, or construction without a City of Miami NPDES permit permit approval.
  • Do not remove or relocate any trees without the benefit of a tree permit.
  • Maintain all best management practices in good condition and practice good housekeeping.
  • Violations Fine for non-compliance run from $1,000 up to $5,000 per violation per day per City Ordinance 13081.
  • Oil and diesel spills must be contained and treated immediately and a report filed with the City and DERM.
  • Please call Public Works NPDES Section for additional information at (305) 416- 1295.
