limitations of any Colorado agency requirements. No water is <br />• anticipated to be discharged from the underground mine. Likewise, no <br />acid mine drainage of pH equal to or less than 6.0 is expected. <br />Historically, the Coal Gulch Coal Mine has experienced some pH problems <br />with water sampled in the pond left at the conclusion of the previous <br />surface operations. As reported in Section 2.04.7, the pH values of <br />water samples taken from this pond were much less than 6.0. Values for <br />pH were found to occur around 3.0. Peerless Resources believes the <br />reasons for this low pH are as follows: <br />• The pond has no outlet, and water has stagnated in the pond <br />since the late 1970's. <br />• The water in the pond results from surface runoff. <br /> • The coal seam previously mined was not covered and has been <br />• left exposed to interact with surface water and the air. <br />• The interaction of surface water and coal and air (along with <br />no outflow) has created a situation where the pH of the water <br />has decreased to its present condition. <br />With proper safeguards such as covering the coal seam and preventing <br />surface water and air from reacting with the coal, Peerless Resources <br />does not anticipate any future problems with low pH water at the site. <br />In the vicinity of Peerless Resources operations, none of the water <br />sampled in surrounding drainages have ranged outside of 6.0 and 9.0; <br />therefore, with proper mining and reclamation techniques described <br />above, it is anticipated that no acid drainage will occur as the <br />operations move northwestward into the block of coal found in Section <br />16. <br />• <br />4.05-3 <br />
