Hawkke’s highly specialized UST decommissioning teams have permanently closed thousands of underground and aboveground storage tanks (USTs and ASTs). That includes tanks with ancillary fuel system components like product lines, dispensers, and gauging equipment.

Risky Site? Bring in a Closer

We’ve closed UST’s where access or structural integrity are tricky. Back to front, our teams know the caution, hazards, and safety procedures that come with this type of work.

Upon arrival our teams evaluate the site, find potential hazards and mitigations, and communicate them to all members. We document the process with a job hazard analysis (JHA).

We operate with the understanding that incidents and near misses are preventable. Where every detail counts, we’re all in, making sure the closure process mitigates risks until a tank is destroyed, no longer usable, or until the site’s restored to a practicable extent.

What We Offer

We’ve performed storage tank closures on everything, from single 300 gallon petroleum tanks to large UST “farms” with tanks holding 40,000 to 100,000 gallons. We’ve closed all types of petroleum product UST systems, including waste oil, hydraulic oil, jet fuel, aviation gas, diesel fuel, heating oil, bunker fuel, kerosene, and gasoline.

If it’s underground, chances are we’ve closed it. Sharpened by experience, our team stands ready to help you out with:

  • Decommissioning underground storage tanks (UST)
  • UST regulations and best practices for removal and closure
  • Engineering controls that complete the job safely
  • UST registration and final reports
  • Placing UST’s in temporary closure, permanent closure through removal methods, or closure by filling in place
  • Backfilling UST excavation sites
    Restoring surface finishes

Leading the Pack

Leadership has its advantages, and we’re fortunate to attract the industry’s best. Our combined experience in the UST closure market puts us at the top. By staying on top, and by striving for excellence in everything we do, we make lives better.

“Just wanted to reach out and express our gratitude on behalf of the Tetra Tech team for the quality of work from the Overley’s crew over the last few UST pulls. Most notable are Tyler and Pavel. These guys ran a clean, safe job site and were great about overcoming unforeseen obstacles to get the job done safely and efficiently. Looking forward to more jobs in the future.”
