Spill Prevention,Control,and Countermeasures Plan City of Ripon Fueling Station Page 2 o Two discharges of oil to navigable waters of the United States, each exceeding 42 gallons (within any 12-month period). The total aboveground oil storage capacity exceeds 10,000 gallons at the Facility; therefore, the Facility is not a Qualified Facility and a Professional Engineer must review and certify this SPCC Plan. 1.2.2 Facility Description and Layout [40 CFR 112.7(a)(3)] The Facility serves primarily as a fueling station and car wash for City of Ripon(City) employees and the public. Additionally, the Facility provides commercial vehicle/equipment storage for the City and is open to the public for commercial fueling. Bulk lubricants/fuels are received by tank truck, while compressed natural gas (CNG) is produced onsite. The Facility is normally unmanned and operates 24 hours a day 7 days per week. The Facility is located at 240 Doak Boulevard,Ripon,San Joaquin County,California.The map coordinates of the Facility are latitude 37.729707°,longitude-121.124075°. Surface runoff flows to central storm drains connected to the City of Ripon storm system. The Car Wash surface runoff flows to nearby drop inlets connected to an oil water separator(OWS)prior to being routed to the sanitary sewer. Surface runoff from the Vehicle/Equipment Storage area flows southwest towards an earthen area along the Facility boundary. Surface runoff ultimately discharges to Stanislaus River which is located approximately 0.33 miles south of the Facility. The approximate location of the Facility is shown in Figure 1,Vicinity Map. The Facility is bounded by agricultural parcels to the east and west, industrial parcels to the north, and sewer treatment ponds to the south. The total area of the property is approximately 1.93 acres of which approximately 84 percent is impervious (buildings, paved areas, driveways, etc.) and the remaining 16 percent area is pervious (landscaped areas). The Facility and surrounding parcels are shown in Figure 2, Site Map. Facility structures include a Fuel Dispenser Canopy, Car Wash, Storage Shed, and Vehicle/Equipment Storage Canopy. There is a total of two aboveground storage tanks (ASTs) at this Facility as detailed in Section 1.2.3. Sanitary wastes are discharged to City of Ripon Publicly Owned Treatment Works(POTW). The layout of the Facility is shown in Figure 3,Facility Diagram. 1.2.3 Facility Containers [40 CFR 112.7(a)(3)(i)through(iii)] The Facility total oil storage capacity as of January 29, 2020, was approximately 20,000 gallons and the total aboveground storage capacity of petroleum applicable to Aboveground Petroleum Storage Act (APSA)was 20,000 gallons.Portable containers of 55 gallons or greater are not stored on-site. The type of oil stored in containers, their storage capacities, identification, discharge prevention measures, and discharge/drainage controls are shown in Table 1. Secondary containment capacities, if containment is present, have also been listed in the right column. Capacity calculations are not applicable to the Facility. Secondary containment structure details are included in Appendix 1. V.44 �i� CONDOR
