If you plan to install a new underground storage tank (UST) system, there are several things to do.

  • You should notify the MDEQ 30 days in advance of the planned installation date of the new UST system by completing a Notice of Upcoming Installation of Underground Storage Tanks form.
  • You must use a contractor who has certification from the Mississippi Department of Environmental Quality (MDEQ) to install USTs.  For a list of companies who have certified workers, click here.
  • Within 30 days of bringing the new UST system in to use, you must submit a completed Notification for Underground Storage Tanks form to MDEQ.  The owner’s and certified installer’s signatures are required on this form.
  • You must pay the annual tank fees.  Once you submit the Notification for Underground Storage Tanks form, you will be assessed a $100 per tank fee on the newly installed tanks.
