Revisions to the Federal UST Regulations

The revised federal UST regulations were signed by the EPA Administrator on June 19, 2015. The revised federal UST regulations were posted in the Federal Register on July 15, 2015. The effective date of the new federal regulations is October 13, 2015 and they will immediately apply to Indian country and non-approved States. Since Louisiana has an approved UST program, the new regulations will not become effective in Louisiana until after Louisiana revises its UST regulations and adopts all of the federal revisions. Approved States have until October 13, 2018 to adopt the revised federal UST regulations and request state program approval.

EPA provided a web link to the final Federal Register posting of the new federal UST regulations with explanations for each change, responses to comments, regulatory impact analysis, redline strikeout version of the federal UST regulations showing all changes made to the existing regulations, questions and answers, and various other resources. The EPA web link is: http://www2.epa.gov/ust/revising-underground-storage-tank-regulations-revisions-existing-requirements-and-new.

The compliance requirements and details for each of the changes will be provided to UST owners, operators, contractors, and equipment testers by LDEQ via outreach training prior to the finalization of the Louisiana UST regulations. LDEQ will be providing outreach on the proposed Louisiana UST regulations in the Operator Training seminars, Enviroschool seminars, on the LDEQ website, and in the UST Newsletter. As stated above, LDEQ will have three years to adopt these requirements into our own regulations. Keep an eye on this webpage for updates and scheduled outreach training.


Please feel free to contact Samuel Broussard, LDEQ USTR Division, at 337-262-5744 or samuel.broussard@la.gov with any questions.
