Sec. 1.
(a) On and after the effective date of this article, for a restricted waste site Type III and a construction/demolition site, the increased height and horizontal expansions of the fill area, beyond that which had been approved previously and for new facilities, must have a barrier between the solid waste and an aquifer. This barrier must:(1) consist of soil, whether undisturbed, constructed, or a combination thereof, with an equivalent hydraulic conductivity through the barrier of less than or equal to 1 × 10-6 centimeters per second; and(2) have a minimum thickness consisting of three (3) feet between the solid waste and any locally useful aquifer.(b) Barrier thickness as specified in subsection (a) may be increased due to cation exchange capacities less than ten (10) milliequivalents per one hundred (100) grams or decreased due to lack of ground water resources in the area or alternate technology such as synthetic liners and leachate collection.
