the feasibility of corrective actions to maintain compliance with ground water quality standards at the compliance boundary; (d) the volume, composition, and physical and chemical characteristics of the leachate; (e) the proximity and withdrawal rates of ground water users, and the availability of alternative water supplies; and (f) any other public health, safety, and welfare effects. (2) The distance between the compliance boundary and the permitted waste boundary must be no greater than 200 feet.The commissioner may require a smaller separation distance if ground water flow rates are very slow or where necessary to provide additional protection to ground water, including sites with downward ground water flow. At existing facilities, including expansion areas,the commissioner may allow a separation distance greater than 200 feet if the following conditions are met: (a) the commissioner determines that the owner or operator has provided sufficient monitoring to assure reliable detection and tracking of pollutant migration within the area enclosed by the compliance boundary, and that the larger separation presents no greater risk to water quality and water use than a separation distance of 200 feet or less; (b) the hydrogeologic evaluation under subpart 3 is complete or will be completed according to a compliance schedule; and (c) the owner or operator revises the cost estimate for contingency action under part 7035.2615 to reflect any greater costs for additional monitoring;ground water containment, removal, and treatment; and other contingency actions, and provides evidence of financial assurance to pay for the increased costs. D. In addition to the compliance boundary required of all facilities under item C,the commissioner shall designate a lower compliance boundary at any facility where there is a potential for substantial pollutant migration downward to a deeper aquifer used locally as a source of water supply.
