AST Configuration & age of ASTHorizontal AST Doublewall steel/approx 15+-yrs old(02/2018) Ia. Useful Life Remaining of AST AST has approximately 15 years of remaining life (,subsection 0410) 2. AST Primary vessel construction(describe) 1000 gals/Waste Oil/UL#11579/UL142-Container/Made to UL 142 construction standard-at least.093in.--2.3622mm steel thickness per UL Std for Safety for Steel Aboveground Tanks for Flammable and Combustible Liquids,suitable for containing waste oil. 3. AST piping(describe) 1 in. hydraulic hose with guick connect supipll to in. elevated Dipe to 1 in. hydraulic hose to (brand) pneumatic pump to in. hydraulic hose to 2 in opening w/fitting,from pump for supply to top of AST. There is an inline check valve between_supply line & pump. The connection snpply hose is kept upright when not in use to avoid any spilling from product in the supply Line. Piping is adequateLy secured, supported & protected against_physical damage and excessive stress due to settlement,vibration, expansion orcontraction, & was tested, found to be in good condition & not leaking. 4. Internal/External pump description external tank- mounted brand illegible pneumatic vump w/2 solenoid 12volt-10-200psi-w/continuous electronic monitoring & pneumaticauto shut down-External pump,which pumps from connecting to waste oil caddies from service area Ancillary equipment is secured to walls& supported and protected ag_anst_p_bysical damage and excessive stress due to settlement,vibration,expansion_ orcontraction (see Pic) 5. AST drawing(provided/drawn: source) (see attached) 6. Design Standard(ASME, UL, etc.) UL 142-Double Wall Steel/Mfr: Modesto Welding 7. AST foundation(describe),concrete sub-floor, Base of AST under UL 142 adeuuate to withstand the load of a full tank-Tank is/is NOW anchored to floor. 8. AST anchoring(seismic zone/floatation risk)AST is/is NOW anchored,with steel flansLesthru feet of tank which are welded to outer shell of tank,&%: in. anchor bolts into the concrete floor. (city,state) Stockton,CA is a(groundshaking) medium to high fault seismic region,likely to experience some moderate to severe earthquake activity, but with a lower level of frequency and intensity than areas which are adjacent to major active faults,which lie directly West of this area. Per CA Dept. ofConaervaliun-CA Geological Survey,this area is a moderate to high ground shaking intensity zone with a low hazard of flooding, and is in a non-saturated zone which nre(rJis a 10w tO moderate ligerefactian hyAard. These anclturs are intended to secure the tank du_!in u_ seismic event. There are two scenarios which would create loads upon them. The first scenario is an emptytank. With an empty tank, the ex ap nsion anchors resist the overturning moment through their tensile (pull-out) ca acit . Since the anchors are installed at the perimeter o the tank the distance between anchors in either directim0provides a sufficient lever arm for the concrete anchors to not exceed their allowable pull-reel capacity. The second load case is with a partially full or full tank_. lir this scenario, because the liquiel fills the bollam ofthe tank and increases its weight, the governinx load care becomes the shear capacity of'llse,concrete expansion anchors In the shear loading, all anchors resist the loads and their allowable capacity is not exceeded. This load
