Site Remediation Program

Storage tanks containing home heating oil – whether they’re located underground, above ground or in the basement – can rust and leak over time, posing a number of environmental and health risks. In the event of a storage tank discharge – where heating oil comes into contact with soil or ground water – New Jersey requires homeowners to take prompt action to minimize those risks.

The minimum work requirements for cleaning up affected properties are defined in the regulation entitled Technical Requirements for Site Remediation (N.J.A.C. 7:26E et seq.). The environmental contractor you hire for your cleanup should be familiar with and follow this rule. This guide is provided as a supplement to help you better understand the cleanup requirements. It should not, however, be used in place of the Technical Requirements.

How Can I Tell If There Is a Problem?

The following could be signs of a leak in your home heating oil tank:.

  1. . Any unexpected/unexplained fuel oil consumption increase that doesn’t appear to be caused by additional use of your heating system (such as during prolonged periods of cold weather).
  2. Water in your underground storage tank.
  3. Consistent problems with your oil burner.
  4. Changes in or loss of vegetation in the area over and around the tank.
  5. Oil odors in areas other than around the oil burner.
  6. Tastes, odors or other problems with your drinking water, if obtained from a well.
  7. Staining on basement walls or floors adjacent to the tank.
  8. Presence of oil or a sheen in the basement sump or French drain.
  9. Oil or sheen in any nearby culverts, drainage ditches, storm drains, streams, or ponds.

    For 1, 2 and 3, first contact the company that services your heating system to rule out a maintenance problem. To determine whether any of the above problems are caused by a leaking fuel oil storage tank, contact an environmental contractor. Your local health department also may be able to provide you with guidance in determining the source of the problem.

What Do I Do If There Is a Leak?

If some type of heating oil discharge has occurred at your home, regardless of the quantity, you must report it to the N.J. Department of Environmental Protection (DEP). Call the DEP’s toll free 24 hour Environmental Action Hot Line at 1-877-WARN DEP (1-877-927-6337) as soon as a discharge is detected.

Next, if the source of your discharge is a leaking tank, contact your fuel oil company and ask that all residual fuel oil be pumped out from the tank. Be sure to ask if any of the oil is reusable.

You also should contact a qualified environmental contractor to perform the cleanup.

A claim should be filed with your insurance company as soon as evidence of a leak is discovered.

What Are the Steps for Cleanup?

The following are some of the steps a contractor will take to clean up fuel oil contamination. All cleanups will differ depending on individual circumstances. These steps are described here to help you better understand the general cleanup process.

  • If the storage tank is underground and must be removed, it will be removed according to local codes and the American Petroleum Institute’s recommended practices. Local construction permits will be required from your municipality.
  • The tank will be thoroughly cleaned and properly disposed of or recycled at a scrap metal facility.
  • Once the tank has been removed, the contractor will excavate any soils believed to be contaminated above the DEP’s cleanup criteria. Soils over the tank may be separated from the contaminated soil and used as fill material, which will save on disposal and fill costs.
  • Once contaminated soil has been removed, soil remaining in the excavation site will be sampled to document the effectiveness of the cleanup. A certified laboratory will analyze the soil samples, and the results will be compared to the DEP’s soil cleanup criteria to determine whether additional cleanup is needed. Soil disposal may represent the largest part of cleanup costs. Therefore, it is important that your contractor accurately determine which soils are suitable for reuse.

It should be noted that if Total Petroleum Hydrocarbon Compounds (TPHC) concentrations are detected in excess of 1,000 parts per million (ppm) in the excavation, the soils must also be tested for Volatile Organic Compounds (VOC) using the appropriate DEP or USEPA test method. The VOC test will be required on 25 percent of the samples with the highest TPHC concentrations exceeding 1,000 ppm of TPHC. Concentrations of TPHC in excess of 10,000 ppm must be remediated. Concentrations below the 10,000 ppm of TPHC may be below DEP soil cleanup criteria, and may not need to be excavated. However, the potential impacts to ground water or other receptors must be evaluated by your contractor and reviewed by DEP to make this determination.

What occurs during the tank removal will determine what additional work, if any, will be needed. If ground water is encountered during the excavation a ground water investigation will be necessary. If there is fuel oil or a sheen floating on the water, the floating fuel oil should be recovered and a ground water cleanup will be required. A ground water investigation will also be required if Bedrock is encountered while excavating. If these situations arise, the cleanup may become more complex.

If you have questions about any aspect of the cleanup, contact your assigned case manager or the duty officer at the Bureau of Southern Field Operations at (609) 584-4150; or the Bureau of Northern Field Operations at (973) 631-6401; Monday through Friday, from 8 a.m. to 5 p.m.

Insurance

You should file a claim with your insurance company as soon as evidence of a leak is discovered. Most policies require at least “prompt” notice of a claim, as well as your assistance in pro-viding information to the insurer. Insurance coverage for cleanup of contamination from leaking residential tanks depends on the language of the individual policy and its interpretation.

You also may want to consider underground storage tank protection programs that may be available from your oil company or fuel oil distributor to insure yourself against future problems.

Financial Assistance

Grant and loan programs are available from the State to provide financial assistance for cleanup costs. To find out if you are eligible, go to www.nj.gov/dep/srp/finance/ustfund/, or contact the Division of Remediation Support, Bureau of Contract and Fund Management, at (609) 777-0101.

Effective Aug. 2, 2006, the Petroleum Underground Storage Tank Remediation, Upgrade and Closure Program provides loans and grants to eligible applicants to help finance project costs for the closure and replacement of a non-leaking residential underground storage tank. This funding assistance is available through the EDA. If you have additional questions, contact EDA Customer Support at (609) 777-4898 or go to the Economic Development Authority’s Web site.

For Additional Information

The DEP maintains a web site offering a wide variety of information and forms concerning the Voluntary Cleanup Program.

To better serve you please have the following information available when calling:

  1. Does a water company supply water to your home, or do you have a potable well?
  2. Is your oil tank above ground or buried underground?
  3. Does your basement have any water collection devices (i.e. sump or french drain)?
  4. If you are unsure if you have a storage tank, how is your home heated?
  5. Are you required to carry flood insurance?

Remember to call the DEP’s toll free 24 hour Environmental Action Hot Line at 1-877-WARN DEP (1-877-927-6337) as soon as a discharge is detected.
