(b) Consideration of Waste Characteristics -- Landfills shall be subject to design and operational requirements dependent on the volume and physical, chemical and biological nature of the wastes. Design requirements shall also be dependent upon the geotechnical and hydrogeological characteristics of the site and surrounding locale. The design proposed by the applicant in conformance with the criteria set forth herein shall be supported by complete hydrogeological and waste characterization data.
(c) Ground Water Monitoring Required -- In accordance with Rule 22.523, a facility or practice shall be designed to prevent the contamination of an underground drinking water beyond the solid waste boundary or beyond an alternative boundary specified in accordance with paragraph (b) of Rule 22.523.

(1) With a compacted clay liner of at least a two-foot thickness with a hydraulic conductivity of no more than 1 x 10-7 cm/sec and a leachate collection system that is designed and constructed to maintain less than a 30-cm depth of leachate over the liner; or
(2) In accordance with a design approved by the Director. The design must ensure that the concentration values specified in Appendix 3 will not be exceeded in the uppermost aquifer at the relevant point of compliance, as specified by the Director under Rule 22.523.
