M <br />i 1 <br />-3- <br />In order to accurately describe the proposed change in. the pond into a <br />permanent impoundment, the description on Page 4.05-7 and 4-16 should <br />be revised as appropriate. <br />On Page 4.05-3 of the application, the statement is made that no acid <br />mine drainage of pH equal to or less than 6.0 is expected. Recent <br />field observations have indicated a seep is evident east of the <br />proposed portal area on the cut bank of the access road. Acidic water <br />and yellowboy staining (ferric hydroxide) have been observed flowing <br />down the roadside ditch. <br />This occurrence is more than likely only seasonal and has yet to be <br />defined. Rule 4.05.2(9) defines the requirements for acid mine <br />drainage treatment. If flow is small and infreouent, a manual system <br />of neutralization can be approved. A plan for treatment of this acid <br />drainage will need to be prepared and submitted to the Division prior <br />to permit approval. Should any assistance be requested on the matter, <br />the applicant is encouraged to contact the Division prior to plan <br />submittal. <br />sr5 <br />9608E <br />
