What Is UST and AST Closure?

Aboveground and underground storage tanks require decommissioning when they start to leak or reach the end of their service life. This process is often referred to as “closure.” It involves a series of essential steps that include obtaining necessary permits, draining, cleaning, and underground storage tank removal or abandonment in place.

The purpose of closure is to make sure unused tanks do not pose a risk to the environment or public safety. Whether removing or leaving in place, it’s crucial to adhere to all environmental regulations and guidelines. Every state and local jurisdiction has different requirements and protocols for underground oil tank removal, UST, and AST closure.

These rules can include specific steps for safe removal or tank abandonment, soil testing procedures, and reporting/documentation regulations. Failure to comply with these unique jurisdictional requirements can lead to severe penalties or legal issues.

UST/AST Closure Requirements and Regulations

The EPA and other government agencies created an intricate set of regulations to ensure environmental and public safety during AST and UST closures. These rules address everything from obtaining necessary permits to handling potential contamination.

Navigating these regulations can be complex, but our team at TEC simplifies the process. Our experts are well-versed in these regulatory landscapes and will guide you through every step of the process to ensure that your tank closure adheres to the appropriate rules.

How Does the UST or AST Closure Process Work?

The closure process involves a systematic approach to safely decommissioning ASTs or USTs. Each project will require a slightly different tactic based on local regulations, tank conditions, and other potentially unforeseen challenges.

The majority of closures involve underground tank removal or abandonment in place. AST closures include removing and hauling them away or on-site decommissioning (crushed and/or cut up).

The below example process is for a UST abandonment job wherein the tank will be left in the ground:

Identification, Notification, & Preparation

  • Coordinate and schedule start date with owner/owner’s representative
  • Provide 30-day notification before UST removal work to relevant authorities (if required)
  • Obtain local building and/or fire marshal permits
  • Provide product submittal data as required
  • Mobilize on-site, layout, secure work areas, and staging/stockpile location
  • Notify local utility and perform tests to locate the tank

Tank Closure

  • Excavate to tank top
  • Cut accessway at tank top
  • Pump out residual waste fuel from USTs and dispose at an approved facility
  • Clean the tank
  • Disconnect tank top accessories and existing piping, remove and dispose of
  • Collect soil samples per state or local jurisdiction either at sides of UST or through the bottom of UST
  • Fill UST with a concrete slurry mix to tank top
  • Add backfill void to grade
  • Produce tank closure report complete with disposal manifests, analytical sampling results, site map, photos, etc.

How Much Does UST or AST Closure Cost?

Various factors can influence a UST or AST closure project, including:

  • Tank material and condition
  • Tank capacity and size
  • Location accessibility
  • Presence of leaks or contamination
  • Local, state, and federal regulatory requirements
  • Permitting
  • Disposal of tank material and any contaminated water or soil
  • Labor and equipment costs
  • Any additional site restoration including landscaping costs after closure

The best way to get an accurate gauge of the total cost of your UST or aboveground oil tank removal project is to contact the experts at TEC.

Frequently Asked Questions

  • The EPA and other local, state, and federal government agencies regulate USTs and ASTs to prevent them from releasing harmful chemicals caused by leaks, overfills, or spills. These chemicals can pollute the environment and cause significant health issues in human beings.

  • The overall time it will take to close a tank varies based on many factors unique to each job. Generally speaking, it can take a few weeks to a few months from start to finish. The best way to understand the total time it can take is to contact TEC and speak to one of our experts.

  • If we find contamination, we will need to remediate it. This process may involve removing and disposing of contaminated soil or water, cleaning the site, and conducting additional testing.

  • Most jurisdictions would ‘rather’ you remove a tank from the ground instead of abandoning it in place. Others mandate that a local state or building inspector will need to pre-inspect your site to allow you to leave it in place. Exceptions include situations where tank removal could potentially jeopardize the structural integrity of a nearby building or where access to that tank is nearly impossible (e.g., in a parking garage or under a deck).
