Chapter 4: The Legal Requirements of Boating
Waste, Oil and Trash Disposal in Florida
and Federal Waters
It is illegal to discharge untreated waste, oil, or trash into any federally controlled or
state waters and for very good reasons.
- Sewage carries disease and is harmful to people, aquatic plants, and animals.
- Trash thrown into the water can injure swimmers and wildlife alike. It
also can plug engine cooling water intakes.
- Pollution is unsightly and takes away from your enjoyment of the water.
Vessel operators need to be aware of the following regulations for waste,
oil, and trash disposal that apply to both federally-controlled and state waters.
The Refuse Act prohibits throwing, discharging, or depositing any refuse matter
(including trash, garbage, oil, and other liquid pollutants) into the waters
of the United States.
Florida’s Clean Boater Program
Boaters sign a pledge promising to read the Clean Boating Habits booklet
and to ensure that they and their passengers will abide by its guidelines.
These boaters may display a Clean Boater sticker on their vessel.
The Clean Boater Pledge:
- Keep Florida's waters free of trash
(bring your trash back)
- Practice proper fueling
- Recycle when possible
- Use pump-out facilities
- Help prevent the spread of exotics
- Be a clean boater example
- Encourage fellow boaters to "Take the Pledge"
- Remember that a clean environment always starts with me

The Clean Marina program is a voluntary program designed to help keep Florida's
coast and waterway resources clean, which consists of Awards & Recognition,
Education Awareness, and Clean Marina/Boatyard Designation. The Program is
funded through grants from the Environmental Protection Agency and the National
Oceanographic and Atmospheric Association and is administered by the Florida
Department of Environmental Protection. The Clean Marina program provides marina
operators/owners with the means to self-assess their facilities through the
use of a checklist provided by the Department of Environmental Protection.
The checklist includes marina activities with associated Marina Environmental
Measures (MEMs); efforts to communicate effectively the standards and procedures
to all employees and agents; and procedures for prompt and appropriate correction
of any violations that may occur if corrective actions need to take place.

Discharge of Sewage and Waste
If you have a recreational vessel with installed toilet facilities, it must
have an operable marine sanitation device (MSD) on board.
There are three types of MSDs.
- Type III MSD, the simplest and most common, consists of holding tanks or
portable toilets. It requires only a small storage space and is simple to
operate. Type III MSDs have the least effect on the environment since the
waste is to be discharged on shore into a local sewage treatment facility.
- Type II MSDs are required for vessels 65 feet and longer and use a combination
of maceration, septic treatment, and chemical treatment to kill bacteria
just prior to discharge. There may be a "Y" valve that directs
untreated waste material for discharge or directs waste material for treatment
prior to discharge. The "Y" valve must be secured to direct waste
to the MSD.
- Type I MSDs are for vessels over 26 feet and under 65 feet long and use
a combination of maceration and chemical treatment to kill bacteria just
prior to discharge. There may be a "Y" valve that directs untreated
waste material for discharge or directs waste material for treatment prior
to discharge. The "Y" valve must be secured to direct waste to
the MSD.
All vessels 26 feet or more in length, which have an enclosed cabin with sleeping
facilities, must be equipped with a toilet if on Florida state waters.
- On a vessel other than a houseboat, the toilet may be portable or a permanently
installed toilet properly attached to a MSD.
- Every houseboat must be equipped with at least one permanently installed
toilet properly attached to a Type III MSD.
All installed devices must be U.S. Coast Guard-certified.

Discharge of Trash
It is illegal to dump refuse, garbage, or plastics into any state or federally-controlled
waters. Many forms of litter can kill birds, fish, and marine mammals.
- You must store trash in a container while on board and place it in a proper
receptacle after returning to shore.
- If boating on federally-controlled waters and your vessel is 26 feet or
longer, you must display a Garbage Disposal Placard in a prominent location.
The Garbage Disposal Placard is a durable sign that is at least 4 x 9 inches
and notifies passengers and crew about discharge restrictions.

What to Do in Case of Discharge
If your vessel discharges oil or hazardous substances in the water, notify
the U.S. Coast Guard by calling 1-800-424-8802. Also notify the State Warning
Point by calling 1-800-320-0519.
Discharge of Oil and Other Hazardous Substances
Regulations issued under the Federal Water Pollution Control Act require all
vessels with propulsion machinery to be able to retain oil mixtures on board.
- You are not allowed to discharge oil or hazardous substances. The penalty
for illegal discharge may be a fine of up to $10,000.
- You are not allowed to dump oil into the bilge of the vessel without means
for proper disposal. Fuel spills can be removed using absorbent bilge pads.
- You must dispose of oil waste at an approved reception facility. On recreational
vessels, a bucket or bailer is adequate for temporary storage prior to disposing
of the oil waste at an approved facility.
- You must notify the U.S. Coast Guard immediately if your vessel discharges
oil or hazardous substances in the water. Call toll-free 1-800-424-8802.
Report the discharge's location, color, source, substances, size, and time
observed. You also must call the State Warning Point and report the discharge.
Discharge of Oil Prohibited
The Federal Water Pollution Control Act prohibits the discharge of oil or
oily waste upon or into any navigable waters of the U.S. The prohibition includes
any discharge which causes a film or discoloration of the surface of the water
or causes a sludge or emulsion beneath the surface of the water. Violators
are subject to substantial civil and/or criminal sanctions including fines
and imprisonment.p

Waste Management Plan
- Ocean-going vessels that are 40 feet or more in length with cooking and
sleeping facilities must have a written Waste Management Plan.
- The captain of the vessel is responsible for implementing the Waste Management
Plan.
- The Waste Management Plan, identifying the vessel's name and home port,
should be posted and should include directives to all persons on board about:
- Discharging sewage and hazardous substances
- Discharging garbage and other food waste
- Disposing of plastics, bottles, and cans
- Reading applicable placards for additional information
- Advising the captain in case of oily discharges or diesel spill
Protect Florida’s Waterways from Invasive
Aquatic Plants
Managing non-native aquatic plants that have been introduced into Florida's
waterways costs millions of dollars each year. These invasive aquatic plants
can:
- Shade out beneficial native submersed plants and lower oxygen levels resulting
in fish kills.
- Hamper the feeding of sport fish producing stunted fish populations.
- Negatively impact local economies.
- Threaten human health by creating ideal mosquito breeding habitats.
- Restrict water flow, resulting in flooding.
- Reduce lakefront esthetics and property values.
- Increase the sedimentation of waterbodies.
Non-native aquatic plants such as hydrilla, water lettuce, and water hyacinth
are invasive weeds that can cause significant environmental harm. Help slow
the spread of these species and prevent additional invasive aquatic species
from becoming established.
Clean all aquatic plants (even small fragments) and mud from your boat and
trailer before leaving a waterway.

Protect Florida’s Seagrasses
Seagrasses are plants totally adapted to living underwater. Their canopy of
leaves that rise into the water and their net of roots that penetrate into
the sediments below create a calm, stable, and protected habitat for a wide
variety of marine life.
- Seagrass
benefits the environment by providing habitat or nursery areas for young
stages of fish, crustaceans, and shellfish, which are important to commercial
and recreational industries. Seagrass also maintains water quality by stabilizing
bottom sediments and removing nutrients from the water column, aiding the
growth of other marine life.
- Seagrass loss in watersheds of estuarine and marine systems is caused by
human activities such as dredge and fill activities, coastal development,
nutrient pollution, degraded water quality, propeller scarring, and interruption
of natural hydrology.
- If boating in shallow areas or seagrass beds, you could see a mud trail
in your wake where your propeller has churned up the bottom, clouded the
water, and likely cut seagrass roots. If you see this trail, you should:
- Stop your vessel.
- Tilt your motor out of the water.
- Pole or walk your vessel out of the shallow area or seagrass bed.
