4.5.1 Effluent Treatment Facilities (40 CFR 112.8(c)(9)) The facility's storm water effluent is allowed to pool on the property and general migrates to the middle of the parcel where it can be collected and/or removed. The storm water runoff does not lead to any water Treatment Facilities and is allowed to evaporate. 4.6 Visible Discharges (40 CFR 112.8(c)(10)) Visible discharges from any container or appurtenance — including seams, gaskets, piping, pumps, valves, rivets, and bolts — are quickly corrected upon discovery. Oil is promptly removed from the enclosure area and disposed of according to the waste disposal method described in Part 5 of this Plan. 4.7 Transfer Operations, Pumping, and In-Plant Processes (40 CFR 112.8(d)) Transfer operations at this facility include: The transfer of fuel from the aboveground storage tank to the vehicles and vessels via a dispenser system for retail customers. The filling of private vessels/vehicles using the appropriate dispenser. The transfer of fuel into or from tanker trucks at the loading/unloading area. All aboveground piping at this facility is raised, not in contact with the ground, and protected against corrosion and is provided with a protective wrapping and coating. When a section of pipe is exposed, it is carefully examined for deterioration. If corrosion damage is found, additional examination and corrective action must be taken as deemed appropriate considering the magnitude of the damage. Additionally, the original installer of the piping would have to have tested the piping prior to county site approval, and a certified & trained inspector/piping tester should conduct integrity and leak testing of piping at the time of installation, modification, construction, relocation, or replacement. Records of all tests are kept at the facility for at least three years. Lines that are not in service or are on standby for an extended period of time are capped or blank-flanged and marked as to their origin. All pipe supports are designed to minimize abrasion & corrosion & to allow for expansion and contraction. Pipe supports are visually inspected during the monthly inspection of the facility. All aboveground piping and valves are examined monthly to assess their condition. Inspection includes aboveground valves, piping, appurtenances, expansion joints, valve glands and bodies, catch pans, pipeline supports, locking of valves, and metal surfaces. Observations are noted on the monthly inspection checklist provided in this Plan. Warning signs are posted at appropriate locations throughout the facility to prevent vehicles from damaging aboveground piping and appurtenances. Most of the 41
