There are predominantly three types of ASTs that <br />are used for this operation; one is the Underwriters Laboratories ([JI.) listed 142 steel AST <br />(single wall), the UL Standard 921 (double wall) and tha other is the listed 2-hour fire <br />protected AST that is built to UL 2085. <br />Proposed installations will need local a��proval/notif cation (permit) and possible plan review <br />documents dependant upon the local code official. Also, MN Pollution Control Agency <br />a�dloz- Department of Natural Resources may require approval when necessary. Effective <br />Au,�ust, 2002, plan review documents are no lon e_�quired to be submitted to the State <br />Fire Marshal Division.

ASTs shall be provided with secondary containment when the quantities exceed the <br />� maximum allowable quantities as specifiedin MSFC Table 27�03.�.1{1) andthe individual <br />� vessel exceed 55 gallons OR multiple vessels exceed 1,000 gallons. The secondary <br />I containment must be able to hold the volume of the largest AST within the secondary <br />containment area. Examples include dikes, drainage control, listed double wall ASTs, and <br />� listed secondary containment built into the AST. Dispensing and fill piping shall not <br />penetrate a dike. For �ut-tk�ez' information, please review MSFC (03) Section 2705.3.7. <br />5. ASTs shall not be filled in excess of 95 percent of their capacity.
