<br />Mr. Mathews <br />September 25, 1995 <br />Page 2 <br />therefore a detailed potentiometric map has not been <br />prepared. Pages 40-42, 52-56 and 60-63 have been updated to <br />more clearly describe the hydrology of the coal seam and the <br />Rollins Sandstone. An attempt to remove the duplicate and <br />contradictory information on these pages has been made. <br />Exhibit 17 has been revised to include a line showing the <br />4750' coal contour line. <br />5. The pages referred to in question 9 cover both mines. <br />Ground water is being monitored in the form of mine inflows <br />studies but no further monitoring is proposed with this <br />submission. <br />6. A spring and seep survey was done along coal and Jerry <br />Creeks in March 1995. Reference to this survey is given on <br />revised page 67 with results given on new page 67a. The <br />location of seeps found during that survey are included on <br />Exhibits 17 and 56. A monitoring plan is included on new <br />page 208b. Page iii has been revised to reference the new <br />Table. <br />7. Historic information is not available on Coal or Jerry <br />Creek. Monitoring sites were identified in March and <br />initial readings taken. Rather than continuous recorders we <br />are proposing crest stage gages and instantaneous readings. <br />Pages 40-41 and 64-65 have been revised to describe these <br />drainage. New page 65a has been included to show the result <br />of initial information on these creeks and pages 208-208a <br />have been revised to include them in the surface water <br />monitoring plan. Exhibits 17 and 56 have been revised to <br />show the surface water monitoring locations associated with <br />these creeks. Page iii has been revised to reference the <br />new Table. <br />8. Mine inflows studies have already been carried out on the <br />Roadside North Portals and will continue to be done. No <br />pages have been revised associated with this question. <br />9. The subsidence monitoring section of the permit has been <br />updated associated with this question. The revised pages <br />include 224-228, 234-235 and 239-242. A subsidence <br />monitoring plan has been included for Coal and Jerry Creeks. <br />References from revised page 80 were added to the reference <br />pages at the end of the PAP. These reference pages have <br />been retyped as pages 1-3. <br />
