The Louisiana Department of Environmental Quality (LDEQ) keeps the records this handbook's Louisiana pages are written from. Its Underground Storage Tank Division runs tank registration and tank cleanups, its Remediation Division runs the cleanup, voluntary cleanup and brownfields programs, and its Waste Permits Division reviews permits for solid and hazardous waste facilities. This page maps each kind of record ASTM E1527-21 asks for to the Louisiana program that holds it, and links a page on each program.
The standard record types, in Louisiana
| ASTM record type | Louisiana program | Agency |
|---|---|---|
| State Superfund equivalent | No single Louisiana list is paired here. The nearest page is the Hazardous Waste Site Cleanup Fund. | LDEQ |
| State hazardous waste facilities | No single Louisiana list is paired here. The Louisiana records that bear on it are Hazardous Waste Notifications and Hazardous Waste Permitting. | LDEQ |
| Landfills and solid waste sites | Solid Waste Permitting | LDEQ |
| Leaking storage tanks | Underground Storage Tank (UST) Remediation | LDEQ |
| Registered storage tanks | Underground Storage Tank (UST) Registrations | LDEQ |
| Institutional and engineering controls | No single Louisiana registry is paired here. The pages read describe Conveyance Notices and Use Restrictions, and the Voluntary Remediation Program's list notes which sites use institutional controls. | LDEQ |
| Voluntary cleanup sites | Voluntary Remediation Program | LDEQ |
| Brownfields sites | No list is paired here, because the pages read link no list of brownfield sites. See the Brownfields Program. | LDEQ |
How far each search reaches is on the ASTM search distances page.
Other Louisiana records worth reading
These are not on ASTM's standard list, but each answers a question a Louisiana Phase I runs into.
- Underground Storage Tank (UST) Closure: the notice before a tank is closed and the assessment after.
- Underground Storage Tank (UST) Compliance: inspections, the delivery prohibition list and the yearly public record reports.
- Motor Fuel Trust Fund: the state fund that reimburses cleanups at eligible tank sites.
- Risk Evaluation / Corrective Action Program (RECAP): the framework cleanups are measured against, and the review letter given for limited assessments.
- Ready for Reuse Program: a determination that a property is acceptable for a stated reuse.
- Solid Waste Notifications and Waste Tires Permitting: industrial waste generator and transporter ID numbers, and tire processors and collection centers.
- Single Point of Contact (SPOC): how spills and incidents are reported to LDEQ.
- Public Records Requests: the Electronic Document Management System and the request form.
One agency, but not every tank or well
LDEQ's Underground Storage Tank Division says it does not regulate aboveground storage tanks. Its registration page says the Louisiana State Fire Marshal's Office regulates them, and that LDEQ's water quality regulations (LAC 33:IX, Chapter 9) apply spill prevention control to aboveground tanks over 660 gallons. A tank search that stops at the UST Division's registrations does not reach aboveground tanks.
Oil and gas is the other gap. LDEQ's registration page leaves out of its tank definition liquid traps and gathering lines directly related to oil or gas production and gathering operations. Its hazardous waste permitting page says a company seeking a no-alternatives determination to inject hazardous waste underground must hold a Class 1 hazardous waste well order issued by the Louisiana Department of Conservation and Energy. The LDEQ pages read describe no oil and gas well records.
For water wells, LDEQ's Remediation page lists two registered water well databases, one by parish and one by longitude and latitude, under an archive heading of additional resources. The page labels them "DNR Registered Water Well Database".
One search that crosses LDEQ's programs
LDEQ says its Electronic Document Management System (EDMS) "contains all official records that have been created or received by LDEQ". The EDMS quick search is the search the department's home page links. LDEQ says documents pertaining to radiation are searchable but not viewable there. The Remediation Division asks that its correspondence carry an Agency Interest (AI) number, and its page for annual legislative reports tells readers to use an Agency Interest number in EDMS. If a site has one, have it before you search.
Getting a file from LDEQ
A listing says a record exists. The reports and letters are in the file. LDEQ's routes are on its Information and Records page:
- The EDMS, which LDEQ says holds all its official records.
- An online public records request form, for records not in EDMS.
- A visit to the Public Records Center at LDEQ headquarters (appointments preferred) or to a regional office (appointments required), from 8 a.m. to 4:30 p.m., Monday through Friday. Appointments are arranged through publicrecords@la.gov.
LDEQ's Customer Service Center answers at 225-219-5337, or toll free at 866-896-5337. The Public Records Requests page has the detail.
