Section 445A.438 - Minimum design criteria: Liners1. When placed on native materials, soil liners must have a minimum thickness of 12 inches and be compacted in lifts which are no more than 6 inches thick. Except when used in tailing impoundments, a soil liner must have a permeability of not more than that exhibited by 12 inches of 1x10-7 cm/sec material.2. Synthetic liners must be rated as having a resistance to the passage of process fluids equal to a coefficient of permeability of 1x10-11 cm/sec.3. The Department shall review for completeness the applicant's evaluation of the following design parameters, where applicable, for a liner: (a) The type of foundation, slope and stability;(b) The over liner protection and provisions for hydraulic relief;(c) The load and means of applying load;(d) The compatibility of a liner with process solutions;(e) The complexity of the leak detection and recovery systems;(f) The depth from the surface to all groundwater; and(g) The liner's ability to remain functionally competent until permanent closure has been completed.Nev.
