Like they were never there

Pacific West’s highly specialized UST removal and 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. We specialize in the safe and efficient removal of USTs, whether they store petroleum, chemicals, or other hazardous substances. Our experienced team employs cutting-edge technology and rigorous environmental compliance to mitigate risks and prevent contamination. We handle every aspect of the removal process, from assessment to soil remediation, ensuring minimal disruption and environmental impact.

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.

prompt & compliant

USTs are commonly used to store various substances, including petroleum products and hazardous chemicals. However, over time, these tanks can deteriorate, potentially leading to leaks and soil or groundwater contamination. Pacific West recognizes the importance of addressing USTs promptly and in compliance with environmental regulations.

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
