  2. Why are Heating Oil Tanks an issue? Tank Deommissioning properly takes a Tank out of service. Leak Fill with Water Weaken and Collapse Float in High Water Table

  3. Floating Gas Tanks

  4. What’s left of 50 year old Tanks

  5. Why are we called? 1.) Real Estate Transactions(More than all other reasons combined). 2.) Refinancing3.) Failing Heating System (Water coming through a hole in the Tank or fuel is rapidly leaking out).4.) Conversion to another Heat source. 5.) Due Diligence(Almost never) FOR SALE

  6. Do I have a Heating Oil Tank? Signs to look for… 1. Vent Pipe 2. Fill Pipe 3. Fuel Lines in Basement Sometimes well hidden…

  7. Do I have a Heating Oil Tank? Signs to look for… New lines… Indicates a past problem with the Heating System. Their remedy was to install new cooper lines. We know lines are new because original lines were iron and there is a patch in the floor. That didn’t solve the problem so they converted to Gas and disconnected the lines. No Decommissioning paper trail. High probability that there is an abandoned leaking Tank on site.

  8. Once the Tank is located… Soil Samples are acquired. TWO (2) soil samples taken at… No more than 6 inches from the opposite ends of the Tank & At ONE to TWO (2) feet below the Tank bottom.

  9. Soil samples are reported as Total Petroleum Hydrocarbons (TPH) measurements of parts per million (ppm). RESULTS: ND means-No Detection of TPH. 0 – 49ppm No DEQ reporting required.50ppm and higher-requires reporting to the DEQ within 72 hours of discovery by either the Tank Owner or service provider. Soil Sample Results 50ppm – 500ppm will require a written DEQ report, but generally no physical cleanup action. Above 500ppm will require a cleanup action beyond a Decommissioning.

  10. Oil Tank Decommissioning is still a voluntary process. March 2000, the DEQ standardized the Decommissioning process by writing a set of procedures to follow, in order for the Decommissioning to be considered “Certified.” Prior to March 2000: Decommissionings did not always include Soil Samples. It was the customers option. Conversions in the past did not always include Decommissionings. Often, customers were advised to fill Tanks with water to ballast them in place. A lot of “out of service” or abandoned Tanks remain with un-resolved issues.

  11. Oil Tank Decommissioning is still a voluntary process. March 2000, the DEQ standardized the Decommissioning process by writing a set of procedures to follow in order, for the Decommissioning to be considered “Certified.” Residential Tank Decommissioning rules are similar to Commercial Tank rules.

  12. Decommissioning Why a pump-out is not enough. Oily Sludge buildup over the years. Tank is cleaned. Backfilled Site Restored The Process of a standard Decommissioning

  13. Decommissioning by Slurry-alternativeMethod

  14. Are basement Tanks Decommissioned? Yes… But don’t forget to remove the vent and fill pipes… This + Automatic Fill = Basement Spill

  15. Soil samples are reported as Total Petroleum Hydrocarbons (TPH) measurements of parts per million (ppm). RESULTS: ND means-No Detection of TPH. 0 – 49ppm No DEQ reporting required.50ppm and higher-requires reporting to the DEQ within 72 hours of discovery by either the Tank Owner or service provider. Soil Sample Results Back to Sample Results 50ppm – 500ppm will require a written DEQ report, but generally no physical cleanup action. Above 500ppm will require a cleanup action beyond a Decommissioning.

  16. The DEQ rules/goal is to protect the Ground Water. SAMPLE RESULTS 500 ppm cleanup level is typical for an Oregon Site.

  17. Cleanup Action Options Matrix Cleanup Involves removal and transport of Contaminated Soil.

  18. Risk Based Corrective Action (RBCA) or Generic Remedy These methods allow Contaminated Soil to be “left in place,” if tested Carcinogen levels are sufficiently low. But… Depending on Soil Test Levels: Effects of nearby Residence may be required, Pathways for vapor intrusion must be noted-Air samples may be required. EXAMPLE OF PATHWAYS: Utility trenches & plumbing. What if Contamination excavation threatens a Structure?

  19. Risk Based Corrective Action (RBCA) or Generic Remedy These methods allow Contaminated Soil to be “left in place” if tested Carcinogen levels are sufficiently low. But… At a later time… old contamination may be mistaken for a new leak.

  20. Ground Water changes the method of Cleanup DEQ will over see the Cleanup.

  21. When the Cleanup is Complete. The final Process is to produce a Environmental Report on the Cleanup Activities. This report ranges from 30 to 40 pages. Copies are sent to: The DEQ with filing fee.2- Copies to the Home Owner.Contractor retains a File Copy for 10 years.

  22. The DEQ DOES NOT oversee most RESIDENTIAL cleanups. THE DEQ does not issue a “No further Action Letter.”The DEQ performs random audits on Contractors to check for Cleanup procedure compliance. YOU SHOULD KNOW… If it is discovered (from an audit) that the contractor did not complete the work to DEQ specifications, the contractor must complete the work at their cost. THE HOME OWNER WILL REMAIN “THE RESPONSIBLE PERSON.”

  27. Tank Replacement Which is better? Above Ground Tanks (AST)What I like:They are easy to monitor. What I don’t Like:Permitting, placement and Seismic Requirements make them expensive to install.They take up space.They are eye sores.They are physically exposed. Underground Steel Tanks (UST)-with AnodesWhat I like:They are inexpensive to put back into the excavation of the old Tank.They save space.They are visually unseen.Cathodic Protection (Anodes) can add up to 30 years of life to the Tank. What I don’t Like:Anodes should be tested and occasionally replaced (inexpensive), Underground Fiberglass TanksAll the advantages of a UST without requiring Cathodic Protection.But it is more expensive than a steel Tank.

  28. Why we prefer underground Tanks
