Petroleum Control
Petroleum in or on
the water is harmful and, in some cases, fatal to aquatic life. Floating petroleum
is particularly bad because it reduces light penetration and the exchange
of oxygen at the water's surface, Floating oil also contaminates the micro
layer. The
micro layer refers to the uppermost portion of the water column. It is home to
thousands of species of plants, animals, and microbes. Ninety-nine percent of
the blue crab larvae feed in the micro layer, which also serves as a nursery ground
for fish. The abundance of life in the micro layer attracts predators: seabirds
from above and fish from below. Pollution in the micro layer; thus, has the potential
to poison much of the aquatic food web,
The
Law
The Federal Water Pollution Control Act (also called the Clean Water
Act) prohibits the discharge of oil or oily waste into or upon the navigable waters
of the United States or the waters of the contiguous zone if such discharge causes
a film or sheen upon, or discoloration of, the surface of the water, or causes
a sludge or emulsion beneath the surface of the water. Violators are subject to
a penalty of $5,000 from the U.S. Coast Guard. State law also prohibits the discharge
of oil. The New York Department of the Environment may impose additional fines.
Fueling
Practices
Gas or diesel may be spilled during the act of fueling: as back splash
out of the fuel intake or as overflow out of the vent fitting. Spills of this
sort harm aquatic life, waste money and can result in stains on the hull and damage
to the gel coat and striping. Follow these
tips to avoid problems:
· Fill tanks to no more than 90 percent capacity. Gas that
is drawn from cool storage tanks will expand as it warms up onboard your vessel
· To determine when the tank is 90 percent full, listen to
the filler pipe, use a sounding stick, and be aware of your tanks volume.
· Rather than filling your tank upon your return to port,
wait and fill it just before leaving on your next trip. This practice will reduce
spills due to thermal expansion because the fuel will be used before it has a
chance to warm up.
· Fill portable tanks ashore where spills are less likely
to occur and easier to clean up.
· Use oil absorbent pads to catch all drips. Slow down at
the beginning and end of fueling.
Bilge Maintenance
Engine oil
tends to accumulate in bilges. If no precautions are taken, the oil is pumped
overboard along with the bilge water Discharging oily water is illegal. To avoid
fines and to protect water quality, follow
these tips:
Keep your engine well tuned to minimize the amount of oil that is released.
Be sure there are no leaking seals, gaskets, or hoses.
· Place oil absorbent materials or a bioremediating bilge
boom in the bilge.
· Place an oil absorbent pad under the engine.
· Replace oil absorbent materials regularly.
· Do not treat oily water with detergents. Soaps pollute
and make clean up impossible. You may be fined up to S25,000 for using soaps to
dissipate oil. · Look for contractors or marinas that offer a bilge pump out service.
Disposal of Oil Absorbent Materials
The
disposal of used oil absorbent material depends on what type of product it is
and how it was used:
· Standard absorbents that are saturated with gasoline may
be air dried and reused.
· Standard absorbents saturated with oil or diesel may be
wrung out over oil recycling bins (if they are saturated with oil or diesel only!)
and reused. Alternatively, they should be double bagged with one plastic bag sealed
inside of another
and tossed in your regular trash.
· Bioremediating bilge booms may be disposed in your regular
trash as long as they are not dripping any liquid. Because the microbes need oxygen
to function, do not seal them in plastic bags.
Emissions
Control Marine engines-especially
2-stroke outboard motors-produce the highest average level of hydrocarbon exhaust
emissions after lawn and garden equipment Hydrocarbon emissions contribute to
ground level ozone, a known health risk. Follow these tips to help your engine
operate as efficiently as possible:· Use the gas to oil ratio recommended by the engine manufacturer.
Too much oil can foul spark plugs and to little can lead to increased engine wear
or even failure.
· Use premium two-cycle engine oil (TC-W3 or TCW4). Premium
oils improve engine performance and reduce pollution because they burn cleaner;
contain more detergents, and prevent formation of carbon deposits.
· Use gasoline with the octane level recommended by the engine
manufacturer.
Preventive Equipment
Products
are available commercially which can help you prevent spills and reduce emissions:
· Install a fuel/air separator along your vent line. These
devices allow air, but not fuel, to escape through a vent opening.
· Attach a safety nozzle to portable gas cans used to fill
outboard engines. These nozzles automatically stop the flow of fuel when the receiving tank
is full. To prevent oily bilge water from being discharged, install a bilge pump
switch that leaves an inch or two of water in the bilge. Alternatively connect
a bilge water filter to your vessel's bilge pump. Filters will remove oil, fuel,
and other petroleum hydrocarbons from the water. When it is time to buy a new
engine, select a fuel efficient, low emission model.
