Chapter 4: The Legal Requirements of Boating
Waste, Oil, and Trash Disposal in Alabama State and Federal Waters
It is illegal to discharge waste, oil, or trash into any Alabama
state or federally-controlled
waters. This is for very good reasons.
- Sewage carries disease and other pollutants that are 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 of any kind (including trash, garbage,
oil, and other liquid pollutants) into the waters of the United
States.
Discharge of
Sewage and Waste
The Marine Sanitation Act 2002-59 or Clean Boating Bill was signed
into law in Alabama on January 31, 2002, and became effective on
October 1, 2003. The new law makes the Department of Conservation
and Natural Resources responsible for enforcing the Act related
to regulating vessel sewage discharges. When the Act is fully implemented,
the Department of Conservation and Natural Resources will inspect
marine sanitation devices on both recreational and residence vessels
and issue yearly MSD inspection decals.

Signs like these are posted at pump-out stations in Alabama.

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.
- Types I and II MSDs are usually found on large
vessels. Waste is treated with special
chemicals to kill bacteria before the waste is discharged.
Types I and II MSDs with "Y" valves that
would direct the waste overboard must be secured
so that the valve cannot be opened. This can be done
by placing a lock or non-reusable seal on the "Y" valve
or by taking the handle off the "Y" valve.
- Type III MSDs provide no treatment and are either
holding tanks or portable toilets.
Collected waste should be taken ashore and disposed of
in a pump-out station or onshore toilet.
Vessels 65 feet or less in length may use a Type I, II,
or III MSD. Vessels over 65 feet in length must install
a Type II or III MSD.
All installed devices must be U.S. Coast Guard–certified.
Vessels with a Type III MSD are prohibited (except in
an emergency) from docking, storing, anchoring or mooring
at a marina unless the marina has a pump-out or waste disposal
system.

Discharge Of Trash
The Act to Prevent Pollution from Ships places limitations on
the discharge of garbage from vessels. 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. The Alabama Code of Law states that discharging trash
into public waters is criminal littering with a minimum fine of
$250.
- 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.

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. Federal law states that you are not allowed
to discharge oil or hazardous substances into the water. The Alabama
Code of Law states that it is a crime for a vessel of more than
25 feet in length to discharge oil products into public waters
of Alabama or within 3 miles of the Alabama shoreline.
- 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 must also call the Alabama Department
of Environmental Management at 334-271-7700 and
report the discharge.
- If boating on federally-controlled
waters and your vessel is 26 feet or longer, you must display
a 5 x 8-inch placard made of durable material, fixed in a conspicuous
place in the machinery spaces or at the bilge pump control
station, stating the following:
Oil Discharge Placard
A 5 x 8-inch sign that states the law pertaining to oil discharge |
 |
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 spills
Stop
the Spread of Nuisance Species
Introducing non-native species into Alabama waters can upset the
balance of the ecosystem, hurting the environment. Aquatic nuisance
species such as zebra mussels, hydrilla, and mitten crabs most
often spread between waterways by hitching a ride on vessels and
trailers. When transplanted into new waters, these organisms proliferate,
displacing native species and damaging the water resource.
To prevent spreading aquatic nuisance species:
- Inspect your vessel and trailer, and remove any plants and
animals you see before leaving the area.
- Drain your motor, live well, and bilge on land before leaving
the area.
- Empty your bait bucket on land. Never release live bait into
a body of water or release aquatic animals from one body of water
into another.
- Rinse your vessel, propeller, trailer, and equipment.
- Air dry your vessel and equipment for as long as possible.
