The Ro111ns Sandstone is the stratigraphically lowest aquifer. It ties <br />below all existing and proposed mine workings. Subsidence from the <br />existing and proposed mine workings wi11 not affect the Ro111ns Sand- <br />stone. <br />No. 3 Mine 1s developed to the 'Anderson' (upper Sunshine seam) above <br />ail three mayor aquifers. Subsidence from proposed mining 1n No. 3 Mine <br />probably will not affect any of the mayor bedrock aquifers. <br />No. I Mine is developed 1n the A-seam dust above the Rollins Sandstone <br />and below the Upper and Middle Sandstone aquifers. The No. 1 Mine work- <br />ings are located approximately 500 ft. below the Middle Sandstone aqul- <br />• fer and 800 ft. below the Upper Sandstone aquifer. Subsidence from min- <br /> ing 1n No. 1 Mine is not expected to have any significant or lasting <br />effect on the overlying aquifers because of the thick interburden lnter- <br />val . <br />In addition to the three ma, or sandstone aquifers, two water-bearing in- <br />tervals were encountered above the Anderson seam during test dr1111ng in <br />the permit area. These water bearing zones were interbedded sandstones <br />of indeterminate thickness and latest extent. Subsidence from mining <br />probably w111 not significantly affect these water-bearing zones because <br />of the 1lmited lateral extent. <br />~;~ <br /> <br />• 11 <br /> <br /> <br />
