Surety bond: Approximately $25,000 for UST contractors. General liability insurance: $1,000,000+ recommended. Workers compensation proof required. Maintain employee license records.

Registered Service Technician required for meter calibration/repair. Annual pump inspections mandatory for all retail fuel dispensers. Placed-in-Service reports required after calibration or repair. Tolerance: ±6 cubic inches per 5-gallon test. Must use certified test measures (NIST traceable). Inspection stickers must be current and visible

Question 4

Class A/B/C Operator Training

Accepted Answer

EPA federal requirement mandates designated operators for each UST facility. Oklahoma uses a tiered Class A/B/C system. Class A: Overall facility compliance responsibility. Class B: Day-to-day operational compliance (on-site). Class C: First responder to alarms (typically station employee). Each UST site must have all three operator classes designated. Training through OCC-approved providers. Records must be maintained on-site and available for inspection. Retraining required within 30 days after significant violation

Question 5

Equipment Testing & Scheduling

Accepted Answer

Certain UST equipment repairs require scheduled witnessed tests by OCC. Drop tube replacements, overfill device repairs, and sump work require pre-scheduling and post-work testing. Drop tube replacement/rebuild requires OCC scheduling (email PSTscheduling@occ.ok.gov). Workflow: Submit scheduling form → Do the work (rebuild) → Schedule witnessed test → Test → Submit post-test forms. After drop tube rebuild, test is required to verify overfill activates at 95% or less. Spill bucket and sump tests required every 3 years. Overfill prevention device testing required after any modification. Keep all test results and scheduling confirmations for 3+ years. OCC-licensed tester must perform witnessed tests. Failure to schedule = potential work stoppage and fines

Question 6

Monthly Inspection Requirements

Accepted Answer

UST facilities must conduct and document monthly inspections of equipment and records. Inspect spill buckets for liquid, debris, or damage. Check overfill prevention devices. Review ATG alarm history and respond to any alarms. Verify dispenser containment sumps are dry. Document all inspections in facility log. Retain records for minimum 3 years. Make records available to OCC inspectors on request

Out-of-date operator training certifications. Unregistered tanks or expired facility permits. Failure to document monthly inspections. ATG alarms not responded to or documented. Spill bucket issues (liquid present, damaged, missing). Missing release detection records (30-day CSLD reports). Unlicensed personnel performing regulated work.
