1. (1) Any installer who intends to install an underground storage tank (UST) system for storage of a regulated substance must, at least fourteen (14) days before installing the tank, notify the department by approved form transmitted via email of intent to install a UST, except that this fourteen (14) day notice requirement may be waived by the department when a release is suspected or in other similarly urgent circumstances. The notification must provide the tank owner’s name, installer name, the name and location of the facility where the UST will be installed, the date that the installation is expected to commence, the date that the tank is expected to be brought in use, UST system information, including tank material, size, manufacturer, piping material, piping type, and manufacturer, release detection equipment, and spill and overfill equipment. The installation notice is valid for one hundred eighty (180) days from receipt by the department and only for the UST system(s) listed on the notice. If installation does not commence within one hundred eighty (180) days of the date on which the department received the notice, a new installation notice must be submitted prior to commencing installation activities.
2. (2) Installers must document compliance with all manufacturer certification or training requirements for tank, piping, release detection equipment, and spill and overfill equipment installed.
3. (3) Installers and manufacturers must be properly registered with the Missouri Department of Agriculture and have a current financial responsibility mechanism that complies with the requirements of 2 CSR 90-30.085.

4. (4) Prior to installation of an underground tank and/or UST system piping intended to be used for storage of a regulated substance, the tank and/or piping must be tested, inspected, and measured in accordance with the manufacturer’s requirements and in accordance with the pre-installation inspection, testing, and/or backfilling sections of either—

8. (7) Should one (1) or more of a manufacturer’s requirements contradict the recommended industry practice(s), the manufacturer’s requirements shall be followed. Backfill materials must meet tank and piping manufacturers’ specifications.

9. (8) The tank and piping system must pass a one-tenth (0.1) gallon/hour system tightness test before the system is brought in-operation. The tank tightness test must be—

   1. (A) A tank tightness test method listed and conducted in accordance with the National Work Group on Leak Detection Evaluations certificate. To obtain a copy, download the appropriate certificate from www.nwglde.org; or
   2. (B) A one-tenth (0.1) gallon/hour third party certified test conducted using the automatic tank gauge with the tank at least ninety-five percent (95%) full.

10. (9) For tank system installations on or after July 1, 2017, before the UST system is brought in-operation—

    1. (A) Spill and overfill prevention equipment must be tested in accordance with 10 CSR 26-2.030;
    2. (B) Secondary containment sumps must be tested in accordance with 10 CSR 26-2.035; and
