<br /> CAUTIONARY NOTE:
<br /> The design data Included in this summary only apply to the tank in the installed condition. If the anchoring
<br /> system design is to be based on this data,the Qualified Design Professional must be certain to note this
<br /> limitation on the design submittals. The tank owner and installer are responsible for anchorage, ballast, and
<br /> anti-flotation requirements encountered during Installation, repair,modification, or exhumation of the tank.
