Proper care and maintenance of your fuel oil tank, lines, and
furnace can reduce your chance of spilling oil and being faced
with costly environmental problems. Fuel oil spills in residential
areas can:
- contaminate drinking water wells, ground water, and soil;
- foul septic systems, requiring their replacement;
- cause odor and health problems in the home;
- contaminate stormwater drains, sewers, drainage ditches and
surface water.
Each of these problems can cost thousands of dollars to correct.
The following tips can help homeowners avoid costly repairs and
problems associated with leaks and spills from home heating oil
systems.
Inspect your tank and heating equipment before and during the
heating season
Check the condition of your tank and lines. The life of your tank
depends on many variables such as the tank construction, tank installation,
soil and ground water conditions, and maintenance of the tank.
Inspect your tank for signs of corrosion.
Make sure the fill cap and the vent cap are in place and tightly
secured.
Check the stability of the tank support and the ground underneath
aboveground tanks. Many tanks have buckled or tipped due to instabilities
and frost heaving. If you have a wooden tank stand, use only pressure
treated lumber. Pressure treated 4x4's make an excellent tank cradle.
Keep the fill pipe accessible and visible to the delivery company.
Place oil lines between tank and furnace either under concrete
or in protective tubing. Check fuel lines for crimps and replace
any damaged fuel lines. Use flexible tubing if frost heaving is
a problem.
Keep all pipe connections clean and tight. Check for drips from
the fittings and the filter.
Clear snow, ice, insect nests or other debris from the tank vent
to allow the tank to properly breathe.
Is there a danger of ice or snow sliding off a roof and damaging
the tank, tank stand, or exposed fuel lines?
Look for signs of spillage near the fill and vent pipes. Stained
soil and rock or distressed vegetation could indicate a fuel spill
has occurred.
Water can collect inside a tank from condensation and cause internal
corrosion. Trapped water can be controlled by removing the water
from a drain plug, using water absorbent socks, or periodically
using additives.
Buried tanks can corrode and leak without obvious signs on the
surface. Be alert for unexplained fuel losses that might point
to leakage.
For inside tanks, be alert for signs of oil in the sump pump pit
and floor drains, and for any oil smell in the basement or crawl
space.
All indoor tanks should have a vent alarm that alerts the fuel
deliverer before the tank is full. When you receive oil, you can
ask the deliverer to verify that the whistle is operating.
Vandalism: to reduce vandalism, break off the ears on the butterfly nut on the goldenrod filter. Recommend a metal canister over the filter instead of glass to eliminate any breakage of the glass filter. The glass filter can easily broken by any object and at any time of year. The entire contents of the tank will be lost if that occurs.
Place copper fuel line in sheathed-flexible (conduit) line.
Strongly recommend replacing fuel tank every 10 years. Corrosion both outside and inside of tank is a huge problem in this environment.
Place 275 gal tanks on side using 6” legs and on a concrete pad.
Things to consider
- Know how to properly measure your tank and calculate the volume
in the tank. Determine your tank size and know when and how much
to order from your delivery company.
- Don't leave your tank unattended during fuel transfers. Avoid
overfills!
- Measure and monitor fuel usage and compare it to past seasons.
A leaking underground fuel tank or line may cause unexplained
increases in fuel consumption.
- Avoid using the area around or under the tank as a storage
area. Heavy items can damage the fill or supply pipes.
- Protect fuel lines from damage by vehicles. Snowmobiles, heavy
equipment, or heavy vehicle loads can damage underground lines
if they are not adequately buried or protected. Aboveground fuel
lines should be encased in protective tubing.
- Consider using a locking cap on the fill pipe to help prevent
vandalism.
- Install a shutoff valve at the tank outlet to isolate the fuel
line in case it starts to leak. If you see a leak in the line,
close the valve to avoid spilling the entire tank volume.
- Do children play around the tank? Protect fuel lines so they
cannot be used as handholds for children climbing on a tank.
- Consider a secondary containment area under an aboveground
tank. A soil, sandbag, or timber berm with a fuel resistant liner
will catch spills before they can contaminate surrounding areas.
- If you take your tank out of service, empty the tank and fuel
lines completely. Abandoned tanks containing residual fuel are "accidents
waiting to happen."
- If your underground tank is taking on water, a leak may be
present. Your oil burner technician can check for water or provide
you with a water-finding paste so you can check for yourself.
If a spill does occur
Accidents can happen, despite your best efforts to prevent them.
In the event of a spill, the main priorities should be stopping
the flow of oil at its source and containing the oil that has spilled.
This will help minimize the impact to the environment and to your
property and that of your neighbors. In most cases, cleanup consists
of the removal and disposal of any contaminated soils or other
media and repair or replacement of leaking tanks and/or fuel lines.
Technical assistance is available from DEC Prevention and Emergency
Response Program staff, who may be contacted at one of the Area
Response Team Offices listed below.
Homeowners are liable under State law for the cleanup of spills
from home heating oil tanks on their property. Sometimes homeowner
insurance policies cover accidental spills from home heating oil
tanks. Many policies, however, specifically exclude such pollution
problems. Check with your agent to find out if you're covered.
Any spill of oil greater than one gallon to land or any amount
to water should be reported to DEC. Fuel deliverers who discover
an existing spill or contamination on a homeowner's property should
inform the homeowner so that he or she can take steps to correct
the situation.

requirements, consult the DEC Prevention and Emergency Response
