• 6. Post-Reclamation Site Drainage <br />Drainage on site will remain the same post mining as during mining. All site runoff will be <br />contained on the site via berms, as seen on Map F. There is no discharge. <br />7. Weed Control <br />Due to the post-mine land use being an industrial yard, weed control will only be necessary on <br />the revegetated slopes and berm. A weed survey will be conducted prior to mining to determine <br />what problems may exist already, if any. Measures will be employed for control of any noxious <br />weed species. Control measures will also be used in the growth of weed species on the reclaimed <br />area threatens further spread of the weeds to nearby areas. A Weed Control Plan will be utilized <br />as follows: <br />- Each April, a weed survey will be conducted of the permit area. <br />• - If any patches or plants have been identified, they will be sprayed by backpack sprayer or 4- <br />wheeler using chemicals approved for use by the weed control staff of Montrose County. <br />- After reclamation, weed surveys and spraying will continue until the perennial cover and <br />production of the site have met DRMS requirements and bond release has been obtained. <br />The Division and Montrose County weed control staff will be consulted regarding any weed <br />infestation area and any control measures prior to their initiation. The plan does not contemplate <br />total weed removal on the property. Past experience shows that some initial weed cover in the <br />first year following the retopsoiling is beneficial to the reclamation effort in dry range site. <br />Weeds tend to provide shade for new grasses and are a means of holding snow on the seedbed <br />longer, protecting it from wind and water erosion until the planted species have taken hold. <br />During the removal of overburden, if an area of heavy seed infestation is encountered, it will be <br />buried in the slopes rather than used as a growth medium. During all phases of the mining <br />operation„ the permit area will be monitored closely to determine if there are any additional <br />• weeds invading the area. If infestations of similar weeds to what is present now are experienced, <br />LaSalle Pit, April 09 E-4
