SECTION 165:15-3-22. Equipment installation

  Fuel Specialists must ensure that tanks and ancillary equipment are installed properly and conform to Commission standards. These standards apply to all facilities. Requirements are listed in detail in OAC 165:25 and 165:26.

(1)   Unattended self-service stations.

(A)   Operating instructions must be conspicuously posted.

(B)   There must be a properly placed emergency shutoff device and conspicuously posted emergency instructions. A telephone or other approved means of communication to notify the fire department.

(2)   Emergency pressure release venting. Aboveground storage tanks must have some form of construction or device that will relieve excessive internal pressure caused by exposure to fires, and have some form of emergency pressure venting. This applies to all compartments and interstitial spaces of tanks, and any enclosed spaces around tanks that can contain liquid.

(3)   Release vent construction. An aboveground tank must have some form of pressure-relieving construction to appropriately control and direct a tank rupture. The tank owner or operator must present, upon request, evidence certifying the construction if the owner has the information.

(4)   Venting and venting specifications. The Fuel Specialist will ensure that vent piping size, height, width, placement and construction meet approved standards, vent vapors upward and do not present collision or fire hazards.

(5)   Piping requirements. The Fuel Specialist must ensure piping is appropriately constructed and protected from physical damage and corrosion where appropriate. Appropriate valves must be in place in piping to prevent leaks and fires. Aboveground storage tank piping and associated parts such as flanges and bolts must be constructed to resist fire to the appropriate extent.

(A)   All new aboveground or underground piping must be installed in accordance with requirements of either OAC 165:25 and 165:26.

(B)   Pressurized piping must have automatic line leak detectors with one sensor, float or similar mechanical device at each submersible pump, or at the lowest sump at the lowest island for each tank, whichever is at the lowest end of the piping gradient.

(6)   Equipment and materials. All pipes, valves, couplings, faucets, flexible connectors, fittings and other pressure-containing parts must meet material specifications and pressure and temperature limitations, adhering to Commission standards. Underground equipment must be cathodically protected where appropriate and aboveground equipment must resist fire to the approved extent. Impact/shear valves and breakaway valves must be in place to prevent leaks and stop their flow in an emergency.

(7)   Electrical equipment. All electrical equipment must meet the requirements NFPA 70, the National Electrical Code, as it applies to wet, damp and hazardous conditions. All electrical wiring and equipment must be suitable for the locations in which it is installed, and required emergency switches must be installed and appropriately placed.

(8)   Vault requirements. Vaults are not required, can be used above or below grade, and must meet NFPA 30 and NFPA 30A requirements. The Fuel Specialist will ensure that those standards are met.

(9)   Fill pipes. Fill pipes must be properly installed and labeled, and overfill sump lids must be color-coded or properly labeled with permanent markings.

(10)   Collision barriers. Aboveground storage tanks and all dispensers exposed to traffic must be resistant to damage from the impact of a motor vehicle or be protected by suitable collision barriers. Secondary containment may serve as a collision barrier.

(11)   Fencing requirements. All aboveground tanks must be enclosed by an appropriate security fence.

(12)   Spill Prevention Control and Countermeasure Plan. Owners or operators of aboveground storage tanks must have a Spill Prevention Control and Countermeasure Plan (SPCC Plan) completed in strict accordance with the requirements of Environmental Protection Agency 40 CFR 112, and updated every five (5) years. Each facility location must have its own plan.

(13)   Corrosion protection. Any portion of a tank or its piping system that routinely contain regulated substances or product and in contact with the soil must be protected from corrosion by a properly engineered, installed and maintained cathodic protection system in accordance with recognized standards of design listed in OAC 165:26 Subchapter 2, Part 4 of Commission rules. A tank sitting on a concrete pad will be considered in contact with the soil unless it is insulated from the concrete by some dielectric material.

(14)   Storage tank spacing and buffer distances.

(A)   Aboveground storage tanks must be appropriately spaced; the Fuel Specialist will determine whether the spacing is in accordance with OAC 165:26 Subchapter 2, Part 1, of Commission rules.

(B)   Minimum distances from aboveground storage tanks must also be maintained between tanks and the nearest important building, fuel dispensers, public ways, and property lines.

(15)   Secondary containment requirements for aboveground storage tanks. Double-walled tanks do not require additional containment if conditions listed in OAC 165:26-2-31 are satisfied.
