support pad-floor. Stockton is a(groundshaking) seismic region, These anchors are intended to secure the tank and the steel berm during a seismic event. There are two scenarios which would create loads upon them. The first scenario is an empty tank. With an empty tank,the expansion anchors resist the overturning moment through their tensile(pull-out)capacity. Since the anchor straps are installed at the perimeter of the tank,the distance between anchors(in either direction)provides a sufficient lever arm for the strap anchors to not exceed their allowable pull-out capacity. The second load case is with a partially full or full tank. In this scenario,because the liquid fills the bottom of the tank and increases its weight,the governing load case becomes the shear capacity of the concrete expansion anchors In the shear loading,all anchors resist the loads and their allowable capacity is not exceeded. This load case is conservative in its analysis since it neglects the friction force created by the weight of the partially full or full tank. This tank's rear is braced against the steel support structure at the wall,which further acts as a barrier to movement in the event of an earthquake.AST is situated in secured lubricants room,at the basement South side of the Service area. The tanks are unlikely to move outside the berm in a seismic event or a flooding event, as are the berms unlikely to move in a seismic or a flooding event. 9. AST will withstand frost-heave XX Yes No AST is anchored with nylon cargo straps over top of AST,set within anchored steel berm,located in secured covered lubricants removal area, not generally subiect to weather conditions 10. AST previously relocated? Yes XX No 11. AST Corrosion Protection Tank is a poly tank,not subiect to normal corrosion events. The tanks are set within a steel berm for secondary containment. The steel berm covered in paint,with no evidence of external corrosion. Tank has no specific corrosion protection beyond the paint. No part of the AST touches the ground. The base of the AST is poly,raised 4 inches from the floor of the steel berm and the steel berm is raised approximately 1 inch above the concrete pad. There is no evidence of internal corrosion taking place. Tank's construction material is carbon poly and the berm construction material is plate steel. 12. AST Spill Prevention Equipment Tank has secondary containment via steel berm. The only spill Prevention equipment is that the piping fills directly into the tank from the top of the tank and thus is not exposed generally to any spills. Should a spill occur,then the steel berm would contain the liquids spilled for eventual clean up. There is no evidence that any spilling has occurred. Filling operations are achieved by gravity feed into the tanks directly via connecting pipe from the temporary containment drip pans. 13. Overfill Protection: Product is not normally handled outside of intended containers. Filling operations are achieved by gravity feed from the articulating drip pans via pipe directly into the tank via the connected opening on the top of the tank. There is no equipment for overfill protection,but the semi-transparent nature of the tank allows easy visual inspection for product levels within the tank to avoid overfills. Should an overfill occur, the amount would be relatively small and contained within the steel berm. Daily visual inspections should be undertaken at this site. A copy of a Daily Inspection Log is attached hereto(but is not the exclusive form for daily inspections.) 14. Toxic Considerations: Ethylene and propylene glycol are toxic by ingestion.Many of the corrosion and antifoaming inhibitors added to antifreeze are also toxic. Propylene glycol is also toxic and combustible and can react with other chemicals.It requires proper storage and handling.Both ethylene and propylene glycol are water soluble.Improper disposal results in the contamination of drinking water,groundwater and land surfaces.Antifreeze is toxic to humans and animals.Waste antifreeze contains heavy metals such as lead, cadmium, and chromium in high enough levels to potentially make it a regulated hazardous waste, so most states strictly regulate antifreeze disposal.Antifreeze generators and state and local programs should not dump spent antifreeze on land or discharge it into a sanitary sewer,storm drain,ditch,dry well,or septic system; dumping antifreeze can cause serious water quality problems and might harm people,pets, or wildlife. The short term storage of waste antifreeze is only acceptable as an interim measure to permit time for the collection of sufficient volumes for cost effective transport to a recycling or disposal facility. It is not normally a reactive nor does it generate large amounts of vapors,which would be a fire hazard,however,this
