# ALTERNATIVE / RENEWABLE FUELS COMPATIBILITY FORM

Storage Tank System Checklist for Equipment Compatibility

for E-blend Fuels (greater than 10% ethano l by volume) or Bio Diesel Products

OPS storage tank regulations 7 C.C.R. 1101- 14 §2-3-3 and §3-4-4 address compatibility re quirements for UST and AST systems. OPS regulations state that

owners/operators must use an UST system or an AST system made of or lined with materials that are compatible with the substance stored in the UST or AST.

Product piping, including piping within the dispensers, as well as containment sumps are considered part of the UST or AST syst em, and needs to be compatible

with the substance stored and dispensed through it. All UST or AST systems that store and dispense Alternative / Renewable fuel must be fully compatible.

### The UST system components below must be compatible with the Alternative / Renewable fuel stored and dispensed. Review this chec klist

thoroughly for its requirements before converting to Alternative / Renewable fuel. Enter Model/Brand

, Manufacturer and check either Yes or No

in one or both columns under UL Listed or Manufacturer Approved

.

*Internally lined tanks are not suitable for conversion to storage of Alternative / Renewable fuels, unless a compatibility det ermination analysis has been conducted.

Deadline for determining compatibility is December 31, 2008. Thir d party precision tank and line testing will be required annu ally on “Internally Lined” tanks only.

## Before Alternative / Renewable Fuel is Transferred to the Tank

Once equipment compatibility has been established, the item s below must be completed before Alternative / Renewable fuel can be transferred to the tank.

Check for water in the tank. No level of water is acceptable fo r Alternative / Renewable fuels due to the phase separation pro blems. Y N

All visible fittings and connections at the top of the ta nk are tight (no vapors escape and no water enters). Y N

Sump and spill containment covers prevent water from entering. Y N

Water infiltration problems fixed if necessary. Y N

The tank has been cleaned of all water and sediment. Y N

Clean tank certificate obtained or comparable documentation (e.g., see API Publication 2015, Cleaning Petroleum Storage Tanks a nd

NFPA 326, Standard for the Safeguarding of Tanks and C ontainers for Entry, Cleaning, or Repair, 2005 Edition). Y N

Labeling: identify the fill port and paint acce ss covers according to API RP 1637. Make sure transport driver cannot make the mistake

of delivering Alternative / Renewable fuel to the wrong tank. Label dispenser. Y N
