Is Your Oil Tank Leaking?
What's underneath your flower bed a tank
Yesterday I had the opportunity I did my 375th inspection and interviewed an environmental company while they were testing the soil of a tank on one of my listings.
A steel pike was used to find edge and depth of tank.Two soil samples were taken within 6 inches of the center of each end of the tank, at a depth range of 0″-24″ below the bottom of the tank. This was done with Hand Auger and a Direct Push Core Sampler.
I asked the inspector about the durability of tanks and what parts of the city had the most failures.
It is totally dependent upon the type of tank , its placement , location and the porosity of the soils. The West hills are mostly clay and hold water. Other locations like Lake Oswego and West Linn are l and rocky and porous.
This 1955 tank was installed between a faucet and gutter drain creating additional water exposure. The inspector guessed this tank was 6 feet long and 500 gallon tank. Most tanks like this from between 1920 and 1950 are 10 gage metal and hold up better than the newer tanks that are harder steel and lighter gage.
Does Your Oil Tank look Like This
I had previously believed any soil readings over 50 parts per million diesel hydrocarbons was reportable and needed additional decontamination. Determining remediation appropriate proceedures is quite complex and it is not only based on levels of hydrocarbons, but the kind of chemicals found. Benzine and or tph total petroleum hydrocarbons trigger a higher concern than normal diesel oil findings. A reportable release for DEQ is over 50 parts per million.

I had always thought finding water in the tank was a bad omen. The inspector demonstrated how they check for remaining oil and water in the tank. The tank is tilted slight at the oil deliver pipe end. Making it easier to determine fluid levels. He coated the end of a tape measure with a detector paste to read the amount of water. This tank had only about 1/2 an inch of oil and 1/4 of water.

4. The most contaminated soil remaining on site contains less than 10,000 ppm TPH and less than 0.0083 ppm benzene
5. No PAH analysis is required
6. If the most contaminated soil samples shows petroleum concentrations below 2500ppm no BTEX analysis is required.
There are numerous factors determining whether removal of a tank is necessary. Your environmental company will assess those factors and appraise you of the options.
OIL TANK INSURANCE DO YOU HAVE IT?
We discussed TANK INSURANCE . Evidently standard insurance primarily covers exposure that affects a neighbors property. Not the homeowners decommissioning process. Many of my clients also have paid a premium for peace of mind protection to their Oil delivery companies for years. However, those long term payments offer little or no protection for future tank soil contamination issues.
