Multi-state c-store chain
Annual line tightness on every pressurized product line, triennial spill bucket and sump testing across a multi-state portfolio. Uninterrupted compliance scheduling across multiple contract renewals.
Industries we serve
Six industries, every required test.
Convenience stores, fleet operators, trucking stops, hospitals, airports, and government and defense. Every petroleum site, every state we serve.
Compliance programs across the industries we serve.
Regional fleet network
ATG functional verification plus Stage I and PVV testing per state schedule across fleet depot yards in the Mountain West.
Hospital generator network
Annual compliance package across medical facilities in Utah and Colorado: tank tightness, line tightness, spill bucket, sump. Continuous multi-year coverage.
Agency fuel infrastructure
Triennial compliance bundling across government fuel sites: spill bucket, sump, overfill, line tightness. Multi-year contract relationship.
Convenience stores
A dense petroleum footprint that has to test on schedule without closing the forecourt.
Tell us about your stores →- The full compliance set in one mobilization: line tightness, leak detector certification, ATG functional, spill bucket, sump, and overfill prevention.
- Line tightness annually; the ATG meets the 30-day leak-test requirement under Part 280; spill bucket and sump on the containment cycle (most states every three years).
- One crew works the dispenser island, canopy, and underground network without a second trip, and leaves the site operating.
- Compliance calendar tracked per site and per state, so multi-store renewals land in coordinated visit windows.
- Audit-ready PEI-format records sent after the visit. PTTI prepares them; your operator files with the state.

Fleet operators
Your own yards, your own trucks, the same Part 280 baseline as a retail forecourt.
Tell us about your yards →- The core set at each yard: line tightness, ATG functional, spill bucket, sump, and overfill prevention.
- Carries the Part 280 baseline plus the state operator inspection forms each site requires.
- The schedule is built around a portfolio of yards across more than one state, each on its own compliance clock.
- Annual pressurized tests, recurring ATG verification, and the multi-year containment cycle consolidated into planned visit windows.
- Records returned in each state operator paperwork format, organized as one coordinated set.

Trucking stops
High fuel volume, the full UST set, plus vapor recovery where the state requires it.
Tell us about your stops →- The same Part 280 core as a c-store: line tightness, leak detector, ATG functional, spill bucket, sump, and overfill.
- In vapor-collection states, Stage I vapor recovery and pressure/vacuum vent testing on the same visit.
- PTTI tracks which vapor forms a state requires: PV valves, vent lines, static torque, or a subset.
- One visit covers both the UST tests and the vapor recovery tests, documented before the crew leaves.

Hospital generators
Standby diesel for backup power, tested under the same federal rule as any UST.
Tell us about your generator tanks →- The core work is tank and line integrity plus overfill protection: tank tightness, line tightness, and overfill prevention.
- Tank tightness uses negative pressure through an isolation tree, listening for an audible leak from inside the tank.
- No separate regulatory tier for a medical facility; the same Part 280 framework applies.
- Clean pass-fail records with photo documentation, ready for the facility's own compliance files alongside the state documentation.

Airport jet fuel
Aviation fuel networks on the same Part 280 schedule as ground-fuel infrastructure.
Tell us about your fuel network →- The core integrity and monitoring set: tank tightness, line tightness, leak detector certification, and ATG functional.
- Tank tightness uses the same isolation-tree-and-microphone method PTTI runs on any site.
- Helium leak detection pinpoints a leak after a failed or inconclusive test, so a repair is aimed precisely rather than by excavation guesswork.
- Serves both fixed base operators and commercial jet fuel systems.

Government and defense
Federal, state, municipal, and defense fuel sites on one regulatory baseline.
Tell us about your agency's sites →- The core set: tank tightness, spill bucket, sump, and overfill prevention, with line tightness and ATG where present.
- No separate overlay for a government tank; the same Part 280 rule and tests apply.
- Each site sits inside its state UST program; each agency keeps records to its own format and timeline.
- Records prepared in the format the agency's compliance office needs, scheduled across the agency's sites together.

Industry questions, answered.
Which industries does PTTI service?
PTTI services convenience stores, fleet operators, trucking stops, hospital generator fuel systems, airport jet fuel infrastructure, and government and defense facilities. EPA 40 CFR Part 280 compliance testing is the framework across every industry.
Do you handle multi-site portfolios?
Yes. Multi-site c-store chains, fleet operators, and government agencies get consolidated scheduling and unified reporting across their portfolio. PTTI tracks compliance calendars per site per state, so triennial-cycle tests and annual line tightness scheduling can be bundled into single visit windows.
What's different about hospital generator testing?
Hospital generator fuel systems operate under the same EPA 40 CFR Part 280 framework as other petroleum sites. PTTI documents pass-fail with photo records and inspection forms ready for facility records in addition to the state UST program documentation the operator handles.
Do you service airport fuel infrastructure?
Yes. PTTI tests airport FBO and commercial jet fuel infrastructure under the EPA 40 CFR Part 280 framework. Aviation fuel testing carries the same line tightness, leak detector, and ATG functional schedule as ground-fuel infrastructure, with helium leak detection available for difficult-to-locate failures.
How are government and defense sites handled?
Federal, state, municipal, and defense fuel sites carry the EPA 40 CFR Part 280 baseline. PTTI tracks each state's UST program requirements per site and prepares documentation in the format the agency's compliance office needs.
