1 SECTION FUEL-OIL DISTRIBUTION (APPLIES TO FUEL TANKS FOR GENERATORS) 1.1 SUMMARY A. Storage tanks, fuel oil, tank accessories, piping, valves, and specialties for fuel-oil distribution inside and outside any building must meet all applicable codes. B. General note: Any contiguous facility that has tanks and/or other vessels that can hold 55 gallons or more of oil (including oil in equipment or cooking oils) in an aggregate amount equal to or exceeding 1,320 gallons must have a Spill Prevention Control and Countermeasures (SPCC) Plan. It is important to note that additional tanks or oil-filled equipment at a site currently not subject to the SPCC rule may cause a facility to be subject. This may necessitate possible upgrades of existing equipment to comply. It is a Best Management Practice to install all oil-filled equipment with oil spill prevention and containment, even if not currently subject to the rule, in order to avoid having to upgrade storage areas during a subsequent project and to avoid spills. All petroleum storage tanks at the Medical Center, LLE/COI, River Campus, CVRI, and Data Center are currently subject to the SPCC requirement. The site s SPCC Plan must be updated to reflect any changes in the handling of oil in containers, tanks or equipment capable of holding 55 gallons or more within 6 months of installation. Projects must anticipate a professional engineering fee to upgrade the plan. Contact the Environmental Compliance Manager at prior to tank or oil-filled equipment installation. Designers of tank and other oil-containing systems subject to the SPCC rules found in 40 CFR Part 112 must incorporate these requirements into the design in addition to any other state and federal requirements. 1.2 QUALITY ASSURANCE The designer and installer both are responsible to ensure tank installations meet the requirements: EPA and State and Local Authorities. These include, but may not be limited to: A. 6NYCRR Parts B. Standards: Petroleum Equipment Institute Publications P100 and RP300, NFPA 30, 30A, and 31, requirements of University Insurance carriers such as Factory Mutual. C. 40 CFR Part 112 will apply to a facility subject to the federal SPCC rule. Contact the Manager of Environmental Compliance for a determination of applicability of the SPCC rules before any particular installation. D. NYSDEC SPOTS Memos 10 & 17 E. NYSDEC Underground Non-metallic Piping Policy. F. Any UL requirements or any other applicable standard. 1.3 WARRANTY A. Structural and Corrosion Failure: 30 years. 1.4 UNDERGROUND TANKS A.

Time and date e. Tank identification f. Temperature g. Fuel identification h. Programmable automatic report times i. Programmable alarm limits to warn of: 1) Oil or water in interstice 2) Low level 3) High level 4) High water 5) Theft j. Automatic Inventory Increase (Delivery) report consisting of: 1) Delivery start time and date 2) Beginning inventory 3) Fuel temperature 4) Delivery end time and date 5) Ending inventory 6) Ending fuel temperature 7) Net and gross increase 5. High level enunciator in close proximity to each fill station with integral horn and flasher. Enunciator shall automatically silence in ten (10) seconds without the need to access the control panel. Provide warning sign adjacent to enunciator that reads Warning Tank Overfill Alarm DO NOT OVERFILL. The enunciator shall be equipped with a self-test button and indicator so that its efficacy can be checked on a monthly basis. D. Fill Port Spill Container: A 7 gallon integrally mounted fill port spill catchment basin with full drain, lockable hinged lid, and brass non-sparking padlock. E. Automatic delivery shut-off device capable of 100% delivery shut-off without human intervention if located within 500 feet of a storm drain. No ball-float shut-off valves located within delivery drop tube are to be specified for this purpose. Section Fuel-Oil Distribution Page 3 of 5

4 F. Vent/Vapor Systems Atmospheric Vent: Upward flow vent cap with flame retardant 40-mesh screen extending a minimum of twelve feet (12') above grade. New York Fire Code G. Fuel Oil: Diesel very low sulfur diesel (required by University air permit) if for an emergency generator. H. The fill-port area should be located in a poured concrete pad to both protect the fill ports should equipment be inadvertently driven over them and to help prevent fuel spills from entering the ground. The top of the concrete pad shall be sloped in such a way as to help direct water from accumulating in the fill port and other access ways to the tank. I. As-built drawings of the tank/piping installation reduced to no larger than legal paper size suitable for filing and written certification by the installer that the system has been installed in compliance with the New York Standards for New and Substantially Modified Petroleum Storage Facilities, 6NYCRR Part 614 shall be given to the Manager of Environmental Compliance at the point of time the tanks system is turned over to the University. J. In the case of underground tanks, each component must be inspected by the owner designated representative prior to its being buried. 1.5 ABOVE GROUND TANKS A. Above ground tank systems shall be constructed and installed per the specifications found in 6NYCRR Parts , NFPA as well as other applicable state and local regulations including 40 CFR Part 112. B. Color Code all fill ports to identify product inside tank in a manner consistent with the color and symbol code of the American Petroleum Institute, as follows: 1. Fuel Oil #1: Purple with yellow bar 2. Fuel Oil #2: Green (note: this is oil used in external combustion boilers) 3. Diesel Fuel #2: Yellow (note that NYSDEC has determined that oil used to power internal combustion engines such as emergency generators is number 2 diesel). This coding is independent of whether it is taxed or not. Generator tank fill ports are to be painted yellow. 4. In addition, the marking must be hexagonal in shape for distillate fuels. As required in Part 613.3(3). C. Signage near Fill Port: The tank must be clearly marked near the fill port with the following markings on either a permanent sign or stencil that is clearly visible to the delivery person: 1. Tank ID (assigned by UR as used to register with NYSDEC) 2. Fuel type (typically diesel) 3. Design Capacity of tank 4. Working Capacity of tank (typically 90% of design) D. Spill Prevention and Containment: Refer to NYSDEC SPOTS Memo's 10 &17 regarding the need for secondary containment. Note that most University storm drains discharge directly into the Genesee River. NYSDEC SPOTS Memo #10 determines that a tank located within 500 feet of a storm drain is presumptive evidence of the likelihood of a potential for a release into the waters of the state. All of the likely scenarios for a release in Spots 10 &17 must be addressed including secondary containment configuration of the tank, filling operations and plausible generator system failures that might cause a release such as a hose breaking.

5 Protection must not rely on an operator or other person's response. Automatic delivery shut-off devices, adequate dikes/beams or other approved means to prevent a release must be incorporated into the tank system's design. The best means is to avoid placing generator/tank systems nears storm drains or other potential routes to the waters of the state. E. Operating valve in place on every line with a gravity head. F. Security and Structural Protection: The tank must be protected and secured from traffic and other hazards including unauthorized tampering as required in both the applicable NYSDEC regulations and Part 112 federal SPCC regulations. G. All above ground tanks installed at the University shall be double walled tanks with interstitial monitors that have a self-test circuit. H. Fill Spill Container: A 7 gallon integrally mounted fill spill catchment basin with full drain, lockable hinged lid, and brass nonsparking padlock. I. Automatic Delivery Shut-off Device: Capable of 100% delivery shut-off without human intervention if located within 500 feet of a storm drain. No ball-float valves located within delivery drop tube are to be specified for this purpose. J. Vent/Vapor Systems Atmospheric Vent: Upward flow vent cap with flame retardant 40-mesh screen extending a minimum of twelve feet (12') above grade. New York Fire Code K. Fuel Oil: Diesel very low sulfur diesel (required by University air permit) if for an emergency generator. L. All above ground tank installations at the University shall be installed so that they can be inspected per Part M. Fire protection and signage required by State and local code must be supplied and installed. This includes a NO SMOKING sign. N. At the time a tank is turned over to the University the tank shall be inspected by a qualified third party selected by the University for independent verification that the tank has been installed per the applicable codes, regulations and University requirements. This may be by the same independent inspector that will update the SPCC. END OF SECTION Section Fuel-Oil Distribution Page 5 of 5
