Month of the Year:
Inspection Date:
Inspector Initials:
Underground storage tanks and motor fuel dispensing equipment
Release detection system
Inspect for proper operation. Run quick “self-test” of automatic tank gauging (ATG) to verify correct operation, or check manual dip stick for wear or warping.
Spill buckets
Ensure spill buckets are clean, empty and free of debris.
Overfill alarm
Inspect for proper operation. Make sure alarm is easily seen and heard.
Impressed current cathodic protection system
Inspect for proper operation. Check and log rectifier at least every 60 days.
Fill and monitoring ports
Inspect to make sure covers and caps are tightly sealed and locked.
Spill and overfill response supplies
Inventory emergency spill response supplies and restock if low. Inspect supplies for deterioration and improper functioning.
Dispenser hoses, nozzles, breakaways
Inspect for loose fittings, deterioration, obvious signs of leakage or improper functioning. Verify that hose retriever is in good condition.
Dispensers/dispenser sumps (internal)
Open dispensers; inspect visible piping, fittings, couplings for leaks. Dispose any water, product. Ensure filter clean, dry, dated. Meter clean, dry, sealed. Union clean, dry. Emergency shutoff valve clean, dry; trip arm not obstructed.
Suction pump and air eliminator clean, dry; air eliminator vent not obstructed; v-belt in good condition. Dispenser cabinet intact; no jagged edges. Remove debris from sump

Nozzle faceplate or facecone
e Ensure it's not torn or missing more than 25% of its surface.
Nozzle
Make sure it's operating properly and has an automatic overfill control mechanism
Vapor processing unit
Check for defects including leaking return line, intermittent process interruptions, low vapor pressure in return to tank line or inoperable Stage I control, e.g. pressure vacuum vent.
