Financial Assurance for PSTs

When Financial Assurance is Required

Financial assurance is the ability to pay for a cleanup of a leak or release from your underground storage tank (UST) system. It should be through an approved mechanism, such as insurance.

UST owners or operators must show financial assurance for corrective action and third-party liability. Corrective action covers the cost to remediate the effects of accidental releases from USTs. Third-party liability compensates others for bodily injury and property damaged by accidental releases from USTs.

AST owners and operators do not need financial assurance.

Financial Assurance Options

Approved types of financial assurance include:

  • Insurance or surety bond – obtained from an insurance agent.
  • Financial test – self-insurance used by large companies.
  • Corporate guaranty – self-insurance by a parent company.
  • Trust or letter of credit – through a bank or credit union.
  • Local-government financial test – self-insurance for local governments.

Whichever you choose, it must meet the requirements in 30 TAC 37, Subchapter IExit the TCEQ and wording must match rule samples exactly. Find sample documents under the attached graphic or figure of the applicable rule.
