iii. Please update the watershed boundaries for the East Taylor, Streeter, <br />Section 16 and Prospect watershed boundaries as necessary. If, based on these <br />changes, any of the watershed boundaries have changed due to the changes in the <br />proposed post-mining topography, Colowyo will (including but not limited to providing <br />new SEDCAD modeling for the affected ponds to ensure they can handle the <br />additional runoff). <br />Response: Drainage boundaries have been revised to match the proposed postmining <br />topography on both Maps 12 and Maps 41141A. Revised SEDCAD modeling is <br />provided for all affected watersheds. <br />e. Map 41A does not have the northing and easting grid or datum values like the other <br />maps do. Please add the northing and easting grid and datum values to Map 41A. <br />Response: We have added northing & easting grid and datum values to Map 41A <br />f. Map 12, Map 41 and Map 41A show the watershed boundaries for the South Area <br />and the South Taylor Area, respectively. As stated, there are several sections on that <br />these maps have in common. Please include a complete delineation of all watershed <br />boundaries on Maps 12, 41 and 41A for the boundaries that are shown on both maps. <br />Response: We have reviewed and revised the watershed boundaries and labels for Maps 12 and <br />12A and Map 41 and 41A. Also the small location map in the legend has been <br />modified to show the delineation of the mapping area common to each map. <br />g. Map 41A shows the watershed boundaries for the South Taylor Pit area. The <br />section 21 and Section 28 watershed boundaries are delineated but not labeled. Please <br />label the Section 21 and Section 28 watershed boundaries on Map 41A. <br />Response: All watershed boundaries on Map 41A have been labeled as requested. <br />h. Map 12 and Map 41 show the portion of the South Taylor Pit limit that crosses over <br />into Section 16. This disturbance limit is the currently approved limit. Please change the <br />South Taylor Pit disturbance limit that is currently shown on Map 12 and Map 41 to reflect <br />the changes proposed in Technical Revision 81. This limit includes the Section 16 Pit <br />redisturbance for the temporary overburden stockpile. <br />Response: This change has been made. <br />i. The Section 16 Pond Ditch is a major ditch in the sediment control plan. This ditch <br />collects runoff from the northeast portion of the South Taylor Pit, including the X-Pod and <br />Section 16 dump areas. Please include the Section 16 Pond Ditch on Map 41A. <br />Response: This ditch has been added as requested <br />j. As discussed in several questions above, there will be major changes to, at a <br />minimum, the Taylor Tributary Ditch, the Section 16 Taylor Ditch (Version 2), the East <br />Taylor Ditch and the West Taylor Ditch. Based on these changes, Colowyo will need to <br />include new SEDCAD modeling for the East Taylor Pond. Please include new SEDCAD
