Underground Storage Tank (UST) Compliance

Agency Louisiana Department of Environmental Quality

The Louisiana Department of Environmental Quality (LDEQ) says UST Compliance is aimed at reducing the number of tank releases by preventing them, through scheduled routine inspections at UST facilities. Its compliance page sets the state's Underground Storage Tank Regulations, Title 33, Part XI, beside the federal Energy Policy Act of 2005. LDEQ's compliance page lists the Act's targets: UST inspections, operator training, secondary containment or financial responsibility and installer certification, delivery prohibition, public record, and state compliance reports on government owned or operated tanks.

In a Phase I ESA

ASTM E1527-21 does not name tank compliance records among its standard record sources. They can show how a tank was kept when it was in service, which a registration alone does not. Four items on the page matter to a records review.

Inspections. LDEQ says each underground storage tank is to be re-inspected at least once every three years. It says that as of December 2021 it had completed four 3-year inspection cycles and was in the middle of the fifth.
Red tags and delivery prohibition. A Louisiana rule adopted September 20, 2007 prohibits delivery of regulated substances into a tank that does not meet its requirements. LDEQ's March 14, 2008 notice said it would red tag any tank that is not registered, does not meet the 1998 upgrade requirements, has no established release detection method, or has released product that has not been addressed. LDEQ says it will publish a list of red tagged facilities on its website and update it as facilities are added and removed. The list is linked as UST Red Tagged Facilities.
Secondary containment. LDEQ says its rule, final on October 20, 2008, requires every UST system installed after December 20, 2008 to have secondary containment with monthly interstitial monitoring on the tanks and piping. LDEQ says a single-walled tank placed in the ground before December 20, 2008 was allowed 90 days, until March 20, 2009, to finish installation without meeting the secondary containment requirements. The installation date of a tank therefore says which rules applied.
Public record reports. LDEQ posts a yearly Public Record report. It says the federal requirement is for information on the percentage of tank compliance, the numbers of tanks, facilities and inspections, confirmed releases, and the sources and causes of releases. The most recent report the page lists is for federal fiscal year 2025, and reports back to 2008 are listed. The page describes totals; it does not say the reports list tanks by site.

Where to look a site up

The pages read give no lookup of inspection results. The compliance page lists an address and a UST compliance mailbox for each regional office, for submittals: Acadiana, Capitol, Southeast, Southwest, Kisatchie Central, Northeast and Northwest. LDEQ's Electronic Document Management System holds its official records, through the EDMS quick search.

Getting the file

LDEQ's routes to a file are its Electronic Document Management System, an online public records request form, and visits to its Public Records Center or a regional office. They are described on the Public Records Requests page.
