2.CAMPUS BACKGROUNDThis section provides a description of SPCC-related features and activities at UC San Diego’s maincampus. It provides essential details of the oil storage capacity, passive secondary containmentstructures, active secondary containment measures, potential discharge volumes of onsite containers, andthe discharge direction. This section forms the baseline background information for this SPCC Plan.2.1UC San Diego Main Campus Description2.1.1Location and ActivitiesUC San Diego operates under the University of California System of the State of California. TheUC San Diego main campus comprises over 500 buildings including: administrative, academic,residential, and maintenance buildings, playing fields and gymnasiums, located on approximately1,200 acres in La Jolla, California. The campus is generally bounded by Genesee Ave. to thenorth, Torrey Pines Road and La Jolla Village Drive to the south, Regents Road to the east, andTorrey Pines Road and the Pacific Ocean to the west (Figure 1). I-5 passes through the easternportion of the campus, separating the main campus from the UC San Diego Medical Center andMesa Housing. SIO is located to the southwest of the main campus and is bounded on the west bythe Pacific Ocean.The campus is primarily used for student housing, academic buildings, athletics, administrativeoffices, research, and maintenance services. UC San Diego operates on a year round basis withstudent related activities operated on a quarter basis, with the first quarter beginning in Septemberand ending in December, the second quarter beginning in January and ending in March, and thethird quarter beginning in April and ending in June. During the summer months, the campus isused for summer camps and a limited summer class schedule.Site activities related to the storage and handling of oil in containers equal to or larger than 55gallons (SPCC covered) include:2.1.2 Motor vehicles, maintenance vehicles (trucks, lawn mowers, etc.), public transportation(buses) - gasoline and diesel fuel storage and dispensing; Emergency generators - diesel fuel storage; Electrical transformers – transformer oil storage; Vehicle maintenance – storage of virgin motor oil and collection of used motor oil; Elevators and hydraulics lift systems – hydraulic oil storage; and Drum and aboveground storage tank (AST) storage of petroleum hydrocarbons.Campus Layout and Site PlanThe General Site Map (Figure 2) presents a layout of the campus. The Site Plans (Figures 3-5)present the location and contents of aboveground storage tanks (ASTs), drums, emergencygenerators, mobile generators and refuelers, and transformers. Pursuant to SPCC Rulerequirements for a facility diagram outlined in CFR 112.7(a)(3), the following items are identifiedin the Site Plan:6

2.2 ASTs and USTs (including content and capacity); Mobile portable containers (including content and capacity); Hydraulic operating systems or equipment; Oil-filled electrical transformers (including content and capacity); Oil/water separators (OWS); and Oil transfer areas and unloading areas.Campus DrainageStorm water from paved drives, parking areas, and loading docks throughout the campus is directed to aseries of catch basins which drain to a storm drain system. Depending on location, UC San Diego stormdrains discharge to the City of San Diego storm drain system flowing north towards Sorrento Valley,south towards Rose Creek, and west towards the Pacific Ocean. UC San Diego storm drains in thevicinity of SIO also discharge directly to the Pacific Ocean.Near the Central Garage and the CSC Grounds Shop two OWS separate oil from vehicle wash rack andgrounds maintenance wash rack operations prior to discharge to the sanitary sewer system.Floor drains located inside buildings connect to the sanitary sewer system. All 55-gallon drums eitherhave or are planned to have secondary containment provided by spill pallets or by the room itself whichlimits offsite drainage pathways to the drains only.There are several outdoor oil storage and oil-containing equipment areas that have secondary containmentthat require the management and discharge of accumulated storm water. These areas of secondarycontainment are subject to storm water accumulation, which must be released in accordance with CFR112.8(b)(1-2) and 112.8(c)(3), as discussed in Section 3.5.2.3Campus Storage CapacityA list of oil storage containers regulated under this SPCC plan and their locations within the UC SanDiego campus is provided in Table I and depicted on Figures 3 through 5. All containers with a capacityequal to or greater than 55 gallons are included as part of this SPCC Plan. As of the preparation date ofthis SPCC Plan, UC San Diego’s aboveground oil storage capacity is approximately 200,000 gallons.Passive and active controls implemented to prevent and contain spills of these materials are described inSection 3 of this plan. A description of the locations of oil stored at the campus is provided in thefollowing sections.2.3.1Aboveground Storage Tanks (ASTs)Diesel fuel, hydraulic oil, and waste oil are stored throughout the UC San Diego main campus,with the largest stores being located at: the Campus Services Complex (CSC), Powell StructuralLaboratory, High Bay Physics, Central Utilities Plant (CUP), East Campus Utility Plant, andScripps Institution of Oceanography (SIO) areas.7

UC San Diego also has mobile fuel bowsers which are used to refuel emergency generators andprovide emergency fueling, as necessary. The mobile fuel bowsers are trailer-mounted tankswhich are parked at the CSC, when not in operation.2.3.255-Gallon DrumsFifty-five gallon drums store petroleum hydrocarbons, diesel fuel, and waste oil at variouslocations across the campus. Most of these drums are stored inside buildings. The total capacityof 55-gallon storage is based on a combination of observed conditions and maximum storagecapacity given existing secondary containment pads.2.3.3Elevators and TransformersThe UC San Diego’s main campus has passenger elevators with hydraulic storage capacitiesranging from 80 to 150 gallons.The UC San Diego main campus has electrical transformers with oil storage capacities rangingfrom 100 to 5,160 gallons.2.3.4Emergency Generators (EGs)The UC San Diego main campus currently owns and operates stationary and mobile EGs. MostEGs have double-walled belly tanks ranging from 55 gallons to 7,500 gallons. Others havedouble-walled day tanks ranging from 250 to 1,000 gallons.2.3.5Oil Water SeparatorsBoth OWS are exempt from all SPCC requirements in accordance with Section 112.1(d)(6) anddo not count toward facility storage capacity. Two OWSs are located at the CSC near the PPSGrounds and the Central Garage buildings. One OWS captures oil associated with washing thestreet sweeper and the other captures car/bus wash water.2.3.6Underground Storage TanksAll USTs are exempt from all SPCC requirements in accordance with Section 112.1(d)(4) and donot count toward facility storage capacity. These USTs are regulated under 40 CFR 280 and Title23 California Code of Regulations (CCR) Sections 2632(d)(2), 2632(e)(2) and 2641(h). UC SanDiego monitors USTs according to its UST Monitoring Plan.2.3.7Motive Power ContainersThe fuel stored by motive power containers will not be added to the cumulative campus storagecapacity because of exemption under 40 CFR 112.1(d). Fleet vehicles are considered by the EPAto be motive power containers because the fuel they carry is for self-propulsion (EPA 2008).2.3.8Cooking Oil ASTsAll aboveground cooking oil/grease tanks located at UC San Diego store less than 55-gallonstherefore are not covered as part of this SPCC Plan.8

2.4Oil Handling Activities2.4.1PipingPiping transfers of oil at the UC San Diego campus include: Diesel or gasoline transfer to various sites across campus using the fueling truck; CSC Fueling Island; Central Utilities Plant; Thornton Hospital; EGs with day tanks: –Pacific Hall–EBU-1–EBU-2–ECUP (two EGs)–Geisel Library–CUP (four EGs)–Natural Sciences–Recreation, Intramural, and Athletics Complex (RIMAC)–Sanford Consortium for Regenerative Medicine–SIO T-43;–Stein;–Thornton Hospital;–Warren College Canyon Vista; checkPowell Complex – transfer of hydraulic oil to Powell Composites Laboratory andbetween buildings at High Bay Physics Lab.The piping used for all these transfers is properly supported to minimize abrasion and corrosionand allow for expansion and contraction in accordance with CFR 112.8(d)(3).2.4.2Fuel Loading/UnloadingFuel loading (adding fuel or oil to ASTs, USTs, mobile generators, mobile fuel bowsers, or fleetvehicle) occurs at the following locations: CSC Fueling Island; EGs (belly tanks); CUP; Thornton Hospital; Re-used 55-gallon drums or 330-gallon totes; and9

ASTs (day tanks for EGs).Fuel delivery schedules vary, depending on usage, and all deliveries of fuel are not overseen byUSCD personnel. When USCD personnel are not available to oversee the fueling activities, spillprevention activities are the responsibility of the fueling contractor, pursuant to conditions of theircontract with UC San Diego. UC San Diego-approved fueling procedures, at a minimum, mustbe implemented by all USCD personnel when undergoing fueling activities and by all UC SanDiego contractors during fuel loading or unloading. Complete fueling procedures are provided inAppendix D and are summarize as:2.51.Check the level in the receiving tank for adequate capacity. Chock the wheels of the truckbefore transfer lines are connected.2.Check the transfer hose(s) for leaks, wear, or potentially faulty valves.3.Open the storage tank fill pipe and connect the transfer hose from the tank truck.4.Monitor the level in the tank during fuel transfer.5.After completion of fuel transfer, disconnect the hose from the fill pipe and secure the fillpipe cover. Place the transfer hose(s) back onto the tank truck in its normal storageposition.6.Remove the wheel chocks.7.Inspect the fueling area for any minor or major leaks. If a leak has occurred, followappropriate reporting and notification procedures. Clean-up minor spilled amounts (lessthan one gallon) with appropriate equipment (absorbent pads, speedy dry, etc.)Spill Containment MeasuresThe material and construction of oil storage containers present at the campus are compatible with thematerial stored and conditions of storage such as pressure and temperature.Secondary containment can be provided through passive or active measures. Passive measures arepermanent installations that do not require deployment or action by the owner/operator. Conversely,active measures are those that require deployment or other specific action by the owner/operator. Bothpassive and active secondary containment measures are implemented at UC San Diego’s main campus.2.5.1Passive Secondary ContainmentThe following are passive secondary containment methods that are implemented for bulk storagecontainers at UC San Diego. They provide a means of containment for the largest singlecontainer and sufficient freeboard to contain precipitation.DikingDikes provide secondary containment, or tertiary containment, for many AST and generators asidentified on Table I. In order to provide adequate secondary containment, diked areas must beable to hold 110% capacity of the storage container including calculations for precipitation(standard calculations include precipitation values for a 24-hour, 25-year storm event).55- Gallon Drums10

All 55-gallon drums have, or are planned to have, secondary containment provided by spill palletsor covered spill pallets.Secondary Containment Provided by Building/RoomAll elevator hydraulic reservoirs are located in buildings with equipment rooms, which providesecondary containment.The majority of 55-gallon drums located at UC San Diego’s main campus have secondarycontainment provide by spill pallets but otherwise all indoor drums have secondary containmentprovided through the room in which they are stored.The hydraulic oil tank (7,500-gallon), the “junior” shaker table tank, and each of the three 500gallon pump tanks in the High Bay Physics facility are single-walled steel tanks. The two 330gallon totes are polyethylene and the 2-inch diameter transfer piping is a fiber composite suitablefor high pressure liquid transfer. All are within secondary sized containment structures.2.5.2Active Secondary ContainmentThe SPCC rule allows for the use of sorbent materials and drip pans to function as activesecondary containment measures for other than bulk storage containers (Section 112.7 [c]).These measures may be deployed either before an activity involving the handling of oil starts, orin reaction to a discharge. Spill kits can be used as an active measure during oil transferoperations.Active Measures in Unloading, Loading, and Mobile Refueling AreasLoading/unloading of petroleum products occurs at UC San Diego’s main campus as discussed inSection 2.4.2 (adding fuel or oil to ASTs, USTs, mobile generators, mobile fuel bowsers, or fleetvehicle).The CSC Fueling Island piping consists of two dispensers with flexible hoses and metal nozzles.The nozzles and rubber hose materials are compatible with both gasoline and diesel fuels. Theoperating system, associated with the dispensing nozzles, disconnects the pump power if thedispenser is not activated within 5 seconds of its removal from the cradle. This system must bereset before fuel can be pumped at that dispenser. The hose and nozzle dispensers are alsoequipped with standard break-away fittings to prevent damage to the dispenser and island if avehicle drives away with the nozzle attached to the fuel tank.Fuel delivery trucks and mobile refuelers use a single hose connection to unload fuel to ASTs,USTs, EGs, or vehicles at fueling areas designated on the Site Plan (Figures 3 through 6).Active measures during unloading operations include, but are not limited to, using spill kits tocontain a discharge, placing a drain cover over a sewer drain prior to or in response to adischarge, and placing drip pans under mechanical piping connections to contain small leaks andspills.11

Active Measures for TransformersWith few exceptions, oil-filled transformers have singled-walled steel tanks and do not have sizedsecondary containment provided by dikes. As a result, spill kits will be made available duringmaintenance activities and during inspections to provide an active form of spill countermeasure.The transformer inspection schedule is discussed in Section 3.1.2.2.6SPILL/RELEASE POTENTIAL AND DIRECTION OF FLOWThe sources of potential oil releases at the UC San Diego campus are listed below. This section isintended to provide the information required in section 112.7 (b) of the SPCC Regulations. Controls andcountermeasures implemented by UC San Diego to mitigate or respond to potential releases to theenvironment are described in Sections 3 and 4, respectively. Potential release volumes, direction of flow,and ultimate discharge locations are presented in Table I.2.6.1Fuel Loading/UnloadingA release could occur at the AST or UST locations if the delivery truck’s hoses are not properlyconnected, if hoses or valves fail, if disconnection is not properly performed (i.e., still pumpingwhen hose is disconnected), or if the tank is overfilled.2.6.2Leaky Valves or PipingValves may leak if they are not entirely closed or may leak if they are old and/or corroded.Piping may leak due to corrosion or through fittings. Generally, leaks of these types are slow andwill likely be mitigated through regular monthly inspections conducted for the associatedcontainer, as discussed in Section 3.1.1.As discussed in Section 2.6.5, the only underground piping at UC San Diego’s main campus isthe hydraulic system at the Powell Complex.2.6.3Tank Failure, Rupture or PunctureA release from an AST (including EGs and transformers) may occur if the tank integrity is weak(e.g., slow leak through a weld seam in a tank), or if the tank ruptures due to an outside force(e.g., vehicle hitting a tank). These scenarios are unlikely, but deserve attention due to theproximity of the tanks to vehicular traffic and the Pacific Ocean.2.6.4Mishandling of DrumsDrums are located at various locations across the campus. A release of oil could occur if a drumis knocked over during transport, or inadvertently drained or punctured. If a release occurredmany drums are located in buildings and all drum storage locations have spill kits located nearby.2.6.5Hydraulic Systems at Powell ComplexIt is possible that a release of hydraulic oil from the pumps or the piping at the Powell Complexcould occur if a transfer hose failed. The hydraulic oil from pumps or piping would flow in theconcrete-lined trenches until it reached the closed sump in the Powell Composites building. Fromthere it would be pumped out and disposed of off-site.12

A release to the environment from the hydraulic oil AST (7,500-gallon) in the High Bay Physicsbuilding is unlikely because the tank is located inside the building with adequate epoxy-coatedconcrete secondary containment.A release from the two 330-gallon totes or the “junior” shaker table tank would be contained bythe building, therefore a release to the environment is unlikely. A third tote located outside istypically empty and adequate sized temporary secondary containment is provided when in use.2.7SecurityThe following is a list of site security measures used to mitigate potential releases of oil: A dedicated staff of security personnel monitors the general security for the UC San Diego maincampus 24-hours per day. Campus security personnel are cognizant of oil storage locations; Adequate lighting is provided at areas where oil is stored; Many oil storage and oil-containing equipment locations are fenced and locked or are located inrestricted access areas; and The fueling equipment can be powered off when the campus is closed.2.8Spill HistoryThere have been no reportable releases of oil or oil-containing materials at UC San Diego in the last fiveyears. In the event a reportable release of such materials occurs in the future, this plan will be amended todescribe the incident(s), the clean-up procedures, and the structural and/or non-structural controlssubsequently implemented to minimize the potential for additional releases. Copies of all spill reportsmust be appended to this plan (Appendix F).2.9Equipment Not Yet Fully OperationalThis SPCC Plan meets the requirements of the SPCC Rules. Any compliance issues and their subsequentcorrective actions are listed in Appendix G.13
