The Division of Environmental Response and Remediation (DERR) is proposing changes to R311, the Petroleum Storage Tank (PST) rules.
On July 14, 2022, the Waste Management and Radiation Control Board adopted changes to the Underground Storage Tank rules to address rulemaking requirements for Aboveground Petroleum Storage Tanks (APST) that were mandated by the passage of Senate Bill SB-40, Storage Tanks Amendments, in the 2021 legislative session. As the Division of Environmental Response and Remediation (DERR) has begun implementing the requirements of SB-40 and the recent changes to R311, the need for a few additional changes to R311 has become apparent. These proposed changes address the following issues:
- The definition of an APST. As AST owner/operators began notifying the DERR of their above ground storage tanks it became apparent that there were several types of ASTs that meet the statutory definition of an APST but, in the Division’s opinion, were not tanks the legislature intended to regulate. The changes to the APST definition exclude these ASTs from the regulation.
- Setting the dollar amount of the financial responsibility (FR) requirement. The rule change completed in July 2022 allowed APSTs to utilize any of the underground storage tank FR mechanisms identified in 40 CFR 280 to meet the FR requirement established by SB-40, but failed to clearly establish the dollar amount of FR required. This change sets Utah’s FR requirement for APSTs to the amount required by the federal UST regulation under 40 CFR 280 Subpart H.
- Establish requirements and processes for APST release reporting, investigation, confirmation, response, and corrective action. This change establishes the same requirements and processes for APSTs as that required for federally regulated USTs under 40 CFR 280 Subparts E and F.
Because SB-40 requires all APSTs to meet financial responsibility requirements and obtain a certificate of compliance by July 1, 2023, addressing these issues requires immediate attention so the updated rule will be in place before the July 1 deadline.
