compliance boundary shall be designated at a contact between soil or hydrogeologic units, or other <br /> definable surface within the saturated zone, and shall be located to prevent adverse effects on water <br /> supplies. <br /> E. <br /> The commissioner may designate a surface water compliance boundary if it is determined, by the <br /> analysis under subpart 3, item G, subitem (7) or otherwise,that pollutants entering the ground water <br /> from the facility may migrate to surface water at concentrations that could adversely affect the quality <br /> of surface water. <br /> (1) <br /> The surface water compliance boundary must be designated as a vertical plane extending downward <br /> from the land surface or as some other readily definable plane located between the land disposal facility <br /> and the surface water. <br /> (Z) <br /> The surface water compliance boundary may either replace a portion of the compliance boundary or be <br /> designated in addition to the compliance boundary. The surface water compliance boundary may be <br /> substituted entirely for a portion of the compliance boundary only if the facility is within 500 feet of the <br /> surface water and the commissioner determines that all pollutants entering the ground water from the <br /> facility will discharge into that surface water. <br /> (3) <br /> The commissioner shall establish standards and intervention limits for the surface water compliance <br /> boundary in the facility permit based on the applicable provisions of chapter 7050. If the surface water <br /> in turn recharges an aquifer used as a water supply,the commissioner shall establish standards and <br /> intervention limits protective of both surface water and drinking water. <br /> (4) <br /> The commissioner shall require submission of any facility and site information needed to establish <br /> standards and intervention limits for the surface water compliance boundary, including low-flow stream <br /> discharge rates, mixing characteristics and rates, biological communities, and chemical composition of <br /> the surface water and leachate. <br /> F. <br /> Except as provided in items E and H and this item, pollutant concentrations in ground water must not <br /> exceed the standards listed in this item at or beyond the compliance boundary and at or below the <br /> lower compliance boundary. The standards and intervention limits for these two boundaries are as <br /> follows: <br />
