Single-Source Tank Fabrication, Rigging & Regulatory Startup

Most petroleum contractors rely on out-of-state tank brokers, creating long lead times, freight delays, and split warranty responsibility. Under The APEC Group umbrella, Geo Petroleum partners directly with our sister manufacturing division, Metal Products USA, to fabricate custom UL-listed tanks right here in Houston and deploy our own PEI-certified installation crews to your site.

Frequently Asked Questions

Answers on UL-142 vs. UL-2085 specifications, custom tank capacities, Fire Marshal setbacks, and TCEQ permitting.

UL-142 certifies atmospheric single-wall and double-wall steel aboveground tanks without thermal insulation, typically requiring full NFPA 30 property-line setbacks or exterior concrete dikes. UL-2085 STI Fireguard® tanks incorporate lightweight porous concrete insulation between double steel walls, passing a 2-hour 2,000°F furnace fire test, .30-06 ballistic resistance, and 12,000-lb vehicle impact testing — allowing up to 50% smaller property setbacks without exterior concrete dikes.

All custom steel storage tanks are fabricated in Houston, Texas by our sister division Metal Products USA under The APEC Group umbrella, while Geo Petroleum's PEI-certified crews manage site engineering, rigging, piping, ATG integration, and TCEQ/EPA regulatory registration. This factory-to-forecourt integration eliminates third-party broker markups and scheduling delays.

We fabricate cylindrical and rectangular steel storage vessels ranging from 300 gallons to 50,000 gallons in single-wall, double-wall, and multi-compartment configurations (such as split diesel/DEF or regular/super unleaded compartments). Custom factory packages include structural steel skids, saddles, OSHA stairs and catwalks, submersible pump risers, internal epoxy linings for jet fuel or biodiesel, and pre-plumbed dispensing cabinets.

Yes. Geo Petroleum manages the entire Texas regulatory lifecycle — including local Fire Marshal (AHJ) plan submittals, TCEQ Title 30 TAC Chapter 334 construction notifications and UST/AST registrations, Professional Engineer (P.E.)-certified EPA 40 CFR Part 112 SPCC plans for facilities exceeding 1,320 gallons of aboveground storage, and startup hydrostatic/tightness testing.

Yes. In addition to UL-142, UL-2085 Fireguard®, and STI Flameshield® aboveground tanks, we supply and install UL-58 / STI-P3® cathodically protected steel and composite double-wall Underground Storage Tanks (USTs) in full compliance with PEI RP100, PEI RP200, and TCEQ Chapter 334 secondary containment standards.

We engineer and install fuel storage systems for retail gas stations and travel centers, commercial trucking and municipal fleet depots, hospital and data center mission-critical backup generators, aviation FBOs, construction and agricultural yards, and petrochemical industrial facilities across Houston, Texas, and the Southeast United States.
