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 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.
