If you upgrade a UST system, you must notify the MDEQ. The following are some possible upgrade scenarios:

  • If you plan to replace the old piping with new piping or an exiting tank with a new tank, you must follow closure procedures for the tank and piping (See Closure Guidance Document).  Then you must follow installation procedures for the new piping and tank installation.
  • If you change your leak detection method like from monitoring wells to automatic tank gauging, just indicate the changes on a Notification for Underground Storage Tank form and submit it to this office.
