Miami River: the yard permit owns the bilge

You are at a commercial facility on the Miami River, not asking for a Miami city tour.

The marine operating permit bans bilge cleaners at the dock and any oily sheen.

A house, Tampa, Jacksonville, or a boat outside Florida stops on this page.

Figure — Seal oil that reaches a bilge. At a river yard, pumping that bilge is the permit problem.

Call me back

Two questions. A house, another state, or a city-only request stops here.

Is the work at a commercial marine facility on the Miami River, not a house and not a Tampa or Jacksonville request?
Is the vessel outside Florida — Georgia, Alabama, the Bahamas, or another state?

The answer on the river

A blown stabilizer seal matters here when the oil can reach the bilge and someone is tempted to pump or to “degrease” it at the dock. Miami-Dade requires an annual marine facilities operating permit for the facility types listed under Ordinance 89-104 and Section 24-18. Permit conditions prohibit bilge cleaners or degreasers while a vessel is docked at the facility, and they prohibit bilge wastewater or gray water that causes iridescence or is contaminated by oil, fuel, or other regulated contaminants.

  • The permit is the yard’s, renewed annually. Your actuator is not a substitute for it.
  • Oily bilge water and transmission fluid are named wastes on the county application.
  • Broward’s 10-gallon BMP line is a different county’s sheet. Do not import it.

The rule on this river

The county’s marine facilities annual operating permit page, accessed 8 October 2026, states that Ordinance 89-104 and Section 24-18 require the permit, and that conditions cover hazardous materials, solid waste, and liquid waste including sewage and gray water. The application asks the facility to check oily bilge water and transmission fluid and to name the hauler, the address, and the pickup frequency for liquid waste. That is the paperwork a refit yard on a tight river slip actually lives with. A vacuum-only gyro fault does not fill those boxes. A seal that has oiled the bilge does.

Chapter 24 is the code the permit is issued under. Published permit conditions quote the chapter’s penalty provisions: civil judicial penalties up to $25,000 per day per offense, with criminal penalties the same text also states. Read the permit in the file at the yard before you repeat the number in a letter. The code’s definition of a de minimis quantity expressly includes hydraulic fluids, at a gallon in a closed container or the volume inside a hydraulic reservoir, and it strips de minimis status when the aggregated volume at the facility exceeds 5 gallons. A stabilizer reservoir is not an invisible exemption.

If you skip the permit condition

Pump a sheen because the slip is narrow and the tide is turning, and the permit condition you skipped is the discharge itself. Spray a bilge cleaner to hide the oil and you violate the cleaner ban while the boat is docked. The county’s penalty language is a per-day exposure on the permittee, which is the facility, and the captain who ordered the pump does not become invisible because the permit is in the yard’s name. The diagnostic does not proceed on a boat that is still pumping oil.

Who signs, who pays, how long

The permit names a facility and a cycle. It does not name a diagnostic price.

Checklist for a river-yard seal

  1. Confirm the facility’s marine operating permit is the instrument, not a city slogan.
  2. Do not add bilge cleaner while the boat is docked.
  3. Do not pump wastewater that would sheen.
  4. Match the waste to the hauler listed for oily bilge or transmission fluid.
  5. Treat a gyro vacuum alarm as a second fault unless oil came from that unit’s cooler.

Fee or timeline the document prints

The permit page describes an annual operating permit. It does not, on the page we cite, publish a dollar fee for stabilizer diagnosis. The number that is printed in permit conditions is the Chapter 24 penalty exposure, up to $25,000 per day per offense in the civil judicial clause those permits recite. That is not your invoice. If you need the current application fee, read the county fee schedule or the permit packet. This note will not invent one.

Questions from the wheelhouse

Can I use a bilge cleaner while the boat is at a river yard?

Marine facilities operating permits issued under Chapter 24 tell the facility that bilge cleaners or degreasers are prohibited while vessels are docked there. The same conditions say bilge wastewater or gray water must not cause iridescence or carry oil, fuel, or other regulated contaminants. A stabilizer seal that has already reached the bilge is that wastewater if you pump it.

Does the City of Miami have its own page here?

No. A request that is only “Miami,” with no river facility, stops. The page exists because a commercial yard on the river holds, or should hold, the annual marine facilities operating permit. A house dock does not become that permit by using the city name.

Is transmission fluid on the permit application the same as stabilizer oil?

The county application lists oily bilge water and transmission fluid among the wastes the facility must account for, with the hauler’s name and frequency. Stabilizer hydraulic oil that reaches the bilge is oily bilge water on that form. Do not rename it “cooling water” to skip the line.

What is the penalty language in the permit?

Permit text issued under Chapter 24 states that failure to comply can bring the penalty provisions of that chapter, including civil judicial penalties up to $25,000 per day per offense, and separate criminal amounts the permit also recites. That is a compliance exposure for the permittee. It is not a price for diagnosis, and it is not a quote.
