The New Hampshire Petroleum Fund Program is a financial assistance program for owners of petroleum storage facilities, and owners of public or private water supplies. The program provides "excess insurance" for cleaning up contamination at storage tank facilities and provides funding to cleanup contaminated water supplies due to MtBE and other gasoline ethers.

The program is comprised of four separate funds authorized by state statute. These funds are the Oil Discharge & Disposal Cleanup Fund under authority of RSA 146-D, the Fuel Oil Discharge Cleanup Fund under authority of RSA 146-E, the Motor Oil Discharge Cleanup Fund under authority of RSA 146-F, and the Gasoline Remediation & Elimination of Ethers Fund under authority of RSA 146-G. The RSA 146-D, E & F funds provide "excess insurance" coverage for owners of underground storage tank (UST) facilities, owners of above ground storage tank (AST) facilities, and owners of on-premise-use heating oil facilities (including residential properties). The RSA 146-G fund is available to remedy contamination due to MtBE or other gasoline ethers, and is not an excess insurance program.

Owners of petroleum storage facilities may request reimbursement for corrective action costs incurred due to a facility release. Owners of water supplies may request reimbursement for remedy costs incurred due to MtBE or other gasoline ethers.

In addition to providing financial assistance, the Petroleum Fund Section provides notification of contamination to well owners. Notification covers groundwater contamination discovered on or after July 1, 2002. It applies to contamination that resulted from human activities and, except for MtBE, was detected at concentrations exceeding state drinking water standards. NHDES does not notify for naturally occurring contamination. For the gasoline additive MtBE, the notification action level is 5.0 parts per billion (ppb), below the state standard of 13.0 ppb. ; Notification takes place after NHDES receives information that contamination was detected in a groundwater sample and after we determine that the contamination is eligible for notification. Groundwater samples can be collected from various sampling points, such as: monitoring wells - small wells installed to sample non-potable groundwater; drinking water wells; or, groundwater seepage in an open tank removal excavation. Notifications consist of a one page notice sent by certified mail.

The distance criterion for notifying private property well owners is 500 feet from the contaminated sampling point. The distance criterion is met if any part of a property, even a small corner, intercepts the 500-foot distance. Public water systems are notified when contamination is found within the wellhead protection area of a public water supply well. Wellhead protection areas have been delineated for all public supply wells and are representations of the recharge zone of a well. Local health officers are also notified.
