Underground Storage Tank (UST) Application Form – Fillable PDF

Regulated entities that install, modify, or close an underground storage tank (UST) must submit an official application to the state environmental agency. The UST Application Form is available as a fillable PDF, making it easy to complete on any device.

What Is the UST Application Form?

This form is the UST Notice of Intent to Perform Closure or Change‑In‑Service (PDF: UST‑SURV‑01). It is used to notify the Louisiana Department of Environmental Quality (or the equivalent state agency) 30 days before a permanent closure, significant renovation, or any change in service for an underground storage tank.
