UST & AST Compliance Testing Services
Compliance Verification Programs
Precision UST testing, line leak detection, and regulatory compliance verification. Annual and triennial testing programs for underground storage tank systems under EPA 40 CFR Part 280 and state regulatory frameworks including Wisconsin ATCP 93.
Testing Methods
- Tank Tightness Testing — Precision testing to verify tank integrity and detect product loss
- Line Leak Detector Testing — Annual verification of mechanical and electronic line leak detection systems
- Cathodic Protection Evaluation — Assessment of corrosion protection systems for buried metallic components
- Overfill Prevention Verification — Testing of automatic shutoff, alarm, and ball float valve systems
- Spill Containment Inspection — Visual and functional assessment of spill buckets and catchment systems
Advanced Asset Diagnostics
0.1 GPH tank testing, cathodic protection evaluation, overfill prevention system verification, and stage I/II vapor recovery diagnostics. Comprehensive system-level assessment designed for multi-site operations requiring consistent, defensible diagnostic data across distributed infrastructure.
Diagnostic Capabilities
- 0.1 GPH precision tank testing
- Stage I and Stage II vapor recovery diagnostics
- Pressurized and suction piping system evaluation
- Automatic tank gauge (ATG) verification
- Submersible turbine pump performance assessment
Regulatory Documentation & Oversight
Regulator-ready test reports, compliance documentation packages, and regulatory correspondence support. Documentation designed for defensibility in agency review and enforcement proceedings. Every report includes test methodology, results, regulatory citations, and professional certification.
Digital Compliance Framework
24/7 secure access to every compliance record from any device. USTEX's Digital Compliance Framework eliminates paper-based record keeping with a structured digital archive — searchable, inspection-ready, and organized exactly how regulators expect. Paper-to-digital conversion services available for facilities transitioning from physical filing systems.
Compliance Rescue — Emergency Response
Emergency compliance response for facilities facing regulatory deadlines, notice of violations, or compliance gaps requiring immediate diagnostic intervention. Expedited scheduling and priority documentation delivery for time-sensitive regulatory situations.
Frequently Asked Questions
- What is 0.1 GPH tank testing?
- A high-precision leak detection method that can identify product loss as small as one-tenth of a gallon per hour, meeting EPA requirements for periodic tank tightness testing.
- What does a compliance verification program include?
- Tank tightness testing, line leak detector testing, cathodic protection evaluation, overfill prevention verification, spill containment inspection, and vapor recovery diagnostics with regulator-ready documentation.
