			 MSWLF units and lateral expansions may not be located over a designated sole
			 source aquifer unless the owner or operator can demonstrate during the permit
			 process of WAC
			 173-351-700 or through the permit
			 modification process of WAC
			 173-351-720(6) that the sole source aquifer is not vulnerable to potential groundwater
			 contamination from the active area. Vulnerability is defined as the propensity
			 or likelihood of a sole source aquifer to become contaminated should the
			 integrity of the engineering control (including liners) fail; it is a measure
			 of the propensity to deteriorate the water quality of a sole source aquifer,
			 and takes into account an assessment of the physical barriers, the physical
			 movement of contaminants, the hydraulic properties of the subsurface lithology;
			 the rate of a contaminant plume movement; the physical and chemical
			 characteristics of contaminants; and it also includes an assessment of the
			 likelihood and ease for contaminant removal or clean-up, or the arrest of
			 contamination, so as to not impact any further portion of the designated sole
			 source aquifer. The owner or operator must place the demonstration in the
			 application for a permit under WAC
			 173-351-700 or through the permit
			 modification process of WAC
			 173-351-720(6).
			 Such a vulnerability demonstration must include the submission of a
			 hydrogeologic report as required in WAC
			 173-351-490 and additionally must
			 meet the following performance criteria:
(i)
			 Demonstrates the presence of confining units or other lithology that will
			 prevent the migration of groundwater contamination;
(ii) Addresses the fate and transport of
			 contaminants, including interactions in the lithologic framework,
			 hydrogeochemical facies, contaminant travel times;
(iii) Defines and summarizes the groundwater
			 budgets for the active area and the sole source aquifer including recharge and
			 discharge areas and includes flow net diagrams;
(iv) Provides a contingency and groundwater
			 assessment plan for the immediate arrest of any groundwater contamination and
			 steps to assess the extent of contamination;
(v) Design specifications for the proposed
			 ground and surface water monitoring systems;
(vi) Is prepared by a geologist or other
