NAC444.8891. Above-ground storage tank: Secondary system for containment.

     1. Each storage tank that is above the ground which stores used antifreeze at a facility for the transfer of used antifreeze or a facility for the recycling of used antifreeze must have a secondary system for containment which:

     (a) Includes dikes, berms or retaining walls, or the equivalent, which are impervious to the penetration of used antifreeze;

     (b) Except as otherwise provided in subsection 2, includes a floor, or the equivalent, which covers the entire area within the dike, berm or retaining wall and is impervious to the penetration of used antifreeze; and

     (c) Is large enough to prevent the release of used antifreeze into the soil, groundwater or surface water.

     2. If a storage tank that is above the ground is being used as of October 3, 1996, the floor of the secondary system for containment is not required to cover that portion of the tank which has contact with the ground.
