Storage Tanks FAQ

  • To help determine tank integrity status, know the age of the tank, the type and style of the tank, the conditions of the soil (wet, well-drained…), and the usage history. Sampling surrounding soil and evaluating the site will help clarify if you should suspect a leak. Call to discuss your site situation to get specific advice about how to best predict if your tank has leaked.

  • Underground storage tanks are supposed to last 30 to 40 years. However, rate of corrosion and tank failure is completely dependent on tank type, installation, and site circumstances. In practical use in the Delaware River Basin area (eastern Pennsylvania, New York, New Jersey, and Delaware) a UST life span is typically 15 to 20 years. In recent years, the EPA and federal regulations initiated more stringent standards for leak detection and tank longevity for new UST installations. If you are worried about your UST, the most important factors to consider:

    • Age of tank

    • Quality of tank / wall thickness / protective coating

    • Quality of installation / piping / corrosion protection system

    • Depth of tank

    • Size of tank

    • Moisture content of soil or surrounding materials

    • Fill material used around tank

    • Average rainfall

    • Drainage of tank field

    Warning signs:

    • Tank is more than 15 years old

    • If you accumulate any water in your tank or lines

    • You have problems with your furnace even after servicing and maintenance

    • Your average heating oil consumption has increased

    • You see any oil film on the surface near tank field

    • Tank is out of use

  • Some are. Some are not. State and federal regulations apply to aboveground tanks and underground storage tanks (UST) with large capacity. Other tanks are regulated because of their content — hazardous chemicals for example. Most heating oil storage tanks used for onsite consumption are NOT regulated by the DEP or EPA. In addition, there are some exclusions for farm-use tanks. HOWEVER, any contamination from leaks or spills is regulated by federal and state environmental agencies— regardless of size or use. Some townships and municipalities also have rules governing the removal and installation of both USTs and ASTs (aboveground storage tank). Additional oversight comes from financial lenders who have their own criteria for approved use, removal, and closure.

  • Yes. Out-of-use tanks that have not been properly closed will have residual oil and sludge left in them. Once the tank walls begin to break down and develop pinholes, material will leach into the soil causing contamination.

  • We remove and install all types and sizes of underground and aboveground tanks. In addition, when we remove underground tanks, we provide soil sample results to confirm a clean tank, excavation, and/or back fill. Some townships and municipalities restrict where and how underground tanks can be installed. If you are unsure, give us a call. We can help you determine what options work for you.

  • It depends on available space, security issues, capacity needs, financial limitations, aesthetic requirements, and local ordinances. There are pros and cons to either installation. Call us. We can help you determine what best fits your needs.

  • Call us. We remove and install all types and sizes of underground and aboveground tanks.

  • We remove about 200 residential USTs per year all over the Delaware Valley. In our experience, most standard residential tanks can be removed for $2,000-2,500. That range covers a typical 500-gallon storage tank with reasonable site access, no contents, no contamination, and includes permits, disposal, manifests, and a closure report. You may wonder if it’s so straight forward, why is there such variation in prices and proposals? Budget problems arise from the unknown variables: additional testing, tank location, tank size and shape, excavation depth, leakage, soil and/or groundwater infiltration, residual product, foundation shoring, monitoring systems…. These variables can add tens of thousands of dollars to a project’s costs. This understandably creates tremendous uncertainty- and stress! To limit those unknown factors, EMG provides an onsite investigation prior to submitting a proposal and evaluates the site for potential complications BEFORE the work begins.
