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?
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.
