Leaking Oil Tanks

Selling, buying or listing an older property?

Protect against possible future liabilities. Schedule a site inspection now.

Home owners are often unaware of the presence of old underground oil tanks on their properties. A Cedar Rock site inspection will locate any underground oil or gasoline tanks, and determine whether they have leaked. Cedar Rock can then advise and assist you in meeting regulatory requirements if a tank has leaked.

Selling/Buying Properties with Soil Contamination

Leakage must be reported.

Leakage from oil or gasoline tanks must be reported to the State, and a “Notice of Residual Petroleum” (NRP) must be filed before the property is conveyed. A filed NRP is required before the State will issue a “No Further Action” (NFA) letter for a contaminated site.

The NRP and NFA letter are usually acceptable and sufficient for buyers, lenders and insurers, but in some cases they may require environmental assessment and/or cleanup of the site beyond the requirements of the State.

In many cases, current legislation does not require the removal or abandonment of a leaking residential underground oil tanks, or cleanup of the contaminated soils, but Cedar Rock recommends proper abandonment or removal of an underground oil tank, whether or not it has already leaked, to prevent the kind of expensive situation pictured below.

Aboveground Tank Leaks

Environmental assessment may be required.

Aboveground storage tank (AST) regulations require the removal of leaking ASTs, and soil cleanup or assessment. If the soils cannot be cleaned up to the required standards, further environmental assessment work may be required by the State, and a filed NRP will be required before the property is conveyed.

Aboveground oil tanks are often located in crawlspace or basement areas which makes removal of contaminated soils difficult and expensive. Vapors from oil leaks in these areas may enter the living space of the house and become a significant health issue.

Site Inspections Essential

Protect your investment!

Before you buy or list a property, schedule an inspection to locate any oil tanks, determine whether they have leaked, and assess other relevant factors that can impact the application of the regulations to the property. Cedar Rock will then explain the regulatory requirements that apply to your situation, and outline possible courses of action. This will provide the necessary information to help protect you from the problems and expense that can result from the purchase of a property with a leaking oil tank, or from the delay or loss of a sale.
