A record will be maintained of areas where herbicides are sprayed, the types and mixture of herbicides <br />used, and the date of treatment. This information will be reported in the Annual Reclamation Report. <br />Historically, pest control has not been necessary at the Seneca II Mine. Based on this operating <br />experience, pest control is not anticipated at this time for the Seneca II -W Mine or the II -W South <br />Extension area. Ongoing reclamation monitoring will identify infestations by pests. A pest control <br />plan will be developed similar to the weed control plan discussed above. The specific plan will be <br />developed in consultation with CMLRD and presented as a revision submittal, when necessary. <br />Regrading or Stabilizing Rills and Gullies <br />After an area has been backfilled, graded, topsoiled, and seeded Peabody will monitor the area <br />following spring snowmelt and heavy rains. If observation of the areas indicates that excessive rills <br />and gullies are present or may potentially occur, a closer observation will attempt to determine the <br />cause of the gullying. These areas will be identified on a map. <br />The natural geomorphic processes of the reclaimed area will be given a great deal of consideration, <br />taking into account the slope, aspect, and soil conditions of the site. Further consideration will be <br />given to the normal climatic conditions and rate of vegetation establishment and development in the <br />subject area. Evaluation will include whether the rills and gullies will prohibit successful revegetation <br />or will disrupt the achievement of the postmining land use. <br />After observation, Seneca Coal Company will have a few options to correct the situation. These <br />options will be a direct result of studying the situation and selecting the option that, in the opinion of <br />Peabody, will rectify the erosional problem. <br />One of, or a combination of, the following options and corrective methods will be employed. <br />Improved Channel. If it is determined that topography of the regraded area is such that drainage is <br />concentrated into a particular area, then this area will be improved to accept the runoff. The drainage <br />bottom or channel will be reshaped, if needed. This will be done with either a motor grader or dozer, <br />making the channel in the shape of a V that is approximately 16 feet to 20 feet wide. The channel <br />bottom will either be seeded, covered with erosion matting <br />MR -77 38 Revised 09/13 <br />
