• Division of Wildlife Issues and Responses <br />for June S, 1997 Letter <br />(continued) <br />reviewed at this time. However, the Division will not require the applicant to contain <br />surface water flows. Discharge limitations will apply at this site, as they do at all coal <br />mines in the state as required by the Clean Water Act and other State and Federal laws. <br />Haul road runoff will be treated by using alternative sediment control practices. (see <br />Reduction of stream crossings above) <br />The Division considers this issue to have been adequately addressed. <br />Response <br />No response is necessary for this comment. <br />Frepuencv of monitorine <br />The DOW requests that the applicant conduct water quality monitoring on a montlily basis <br />at the upstream and downstream sites of the Purgatoire as well as at the mouth of Lorencito <br />• Canyon. The applicant has modified the monitoring plan to conduct monthly flow and <br />field monitoring and quarterly water quality sampling at these sites. The Division <br />considers this response adequate. <br />e e <br />No response is necessary for this comment. <br />Lack of topsoil <br />The applicant predicts that due to steep slopes and areas of bedeck exposure, a deftcit of topsoil <br />will exist at the conclusion of surface mining. The DOW requests that the applicant import topsoil <br />to the site to address this shortage. <br />The Division would like the applicant to further investigate topsoil replacement options. The <br />Division is concerned that valuable topsoil is proposed not to be salvaged in certain areas. Topsoil <br />is defined by Rule 4.06.2(2)(b) as soil horizons oR the surface prior to mining that will support <br />plant life. The reclamation plan calls for .7 feet of topsoil to be distributed over 901 acres of the <br />surface mine. However, the Division is confused by permit text on page 2.05-35 which states <br />"reapplication may be limited to south-facing slopes where revegetation conditions will be more <br />difficult". If .7 feet is to be re-applied over 901 acres, why does the permit text indicate <br />. approximately 1/2 of the surface mine area will be reclaimed without topsoil? Information needs <br />to be consistent between what is represented in the various tables and calculations and what is in <br />the permit text. <br />9 <br />
