Please <br />commit to planting a cover crop on any topsoil and or overburden pipe that will be <br />left in place for 180 days or longer. Please provide a seed mixture with the species <br />name and the amount of live seed per acre that will be used for the cover crop. <br />We added language to note 3 on page 3 of Exhibit C to commit to this. We also <br />added the seed mixture to be used to Exhibit C. <br />On the "Reclamation Details" drawing of the pit slope cross-section, it states in the <br />Notes, "Revegetation shall use seed mixes listed in the table, or similar alternate mix <br />based on commercial availability at the time of reclamation". Please remove the <br />italicized statement. Any changes in the approved seed mixtures used for reclamation <br />will need to be approved by the Division prior to the planting a different mixture. <br />Please commit to filing a Technical Revision to the reclamation plan to change the <br />seed mixture that will be used to revegetate the affected land and prior to planting a <br />different seed mixture. <br />Rather than delete the italicized statement, we left it in and then added a statement to <br />this note that says: "In addition, a Technical Revision to the Reclamation Plan will <br />be filed with and approved by the DRMS prior to planting a different seed mixture. " <br />We felt it was important to leave in the italicized statement because it provided an <br />explanation of why the seed mixture might need to change. <br />In regards to the revegetation plan, if the seed mix will be broadcast seeded instead of <br />drill seeded please commit to doubling the pounds of live seed per acre applied. <br />We added a sentence to note 4 on page 3 of Exhibit F which states: "If the seed mix is <br />broadcast seeded instead of drill seeded, the pounds of live seed per acre applied will <br />be doubled. " <br />The configuration of the former affected land after reclamation appears different than <br />the current approved reclamation plan. One significant difference is the south east <br />portion of the mine site where the current processing area is located. The applicant <br />has proposed that the post mining land use of the 53 acres will remain as in industrial <br />area. Please provide a description of how this site will be left after the permit is <br />released, what will be the make-up of this industrial area? For example, what <br />structures will remain (plants, roads... etc), how will the entire 53 acres be protected <br />from wind and water erosion? Overall there is no mention on the text regarding this <br />changed in the reclamation plan. Please state that a portion of the site will remain <br />industrial for a post mine land use. Also, there is no mention in the amendment about <br />the changes of the various ponds and other features of the current reclamation plan. <br />Please provide a summary/ outline of how the reclamation of the entire affected land <br />will change from what is currently approved. <br />We agree that what is shown on the reclamation plan is different than the current <br />approved reclamation plan. What we are showing on the mining and reclamation <br />plan is what is currently occurring at the 35`h Avenue site and what has been shown <br />on the annual reports submitted to the DRMS. The industrial area, which we have
