monitoring plan. Volume III, Tab 3 Baseline Surface and Groundwater Data for the Proposed Permit Area Addition - PR-04 contains Table 4 Monitoring Point Descriptions. This table contains useful descriptions and location information for drill holes used as monitoring wells and for alluvial wells, This table should be updated to include atl current groundwater monitoring wells. Drill holes or monitoring points that are inactive or permanently sealed should be noted in the table. Monitoring point descriptions should be provided for all of the monitoring wells shown on the Hydrological Monitoring Location Map, Map 09. Section 2.04.10, Vegetation Information 9. Seed Mix No. 2 -Meadow Mix, and Seed Mix No. 3 -Upland Mix, contain several aggressive introduced species that have a tendency to out compete the forbs, shrubs and native grasses that are also in these two mixes. The permit text on page 2.05-50 says Seed Mix No. 2 is designed to emphasize the perennial species that were found in the disturbed meadow community. Rather than duplicating a poorly managed, disturbed community, DMG suggests replacing the introduced species listed below with native species that will serve the post mining land use as well or better. Seed Mix No. 3 also contains several introduced grass species and native shrubs. The introduced grass species have a tendency to out compete the shrubs that are also included in the mix. This mix was designed using species that were successful at mines that were reclaimed a number of years ago. Since then, many native seed sources have been developed and aze commercially available. The following species should be removed from Seed Mix No. 2 & No. 3: Agropyron intermedium, Agropyron elongatum, Agropyron spicatum X repens, Agropyron inerrrte, Agropyron sibericum, Bromus inermis, Lolium perenne, Dactylis glomerata and Poa pratensis. Please replace these species with native species. Suggested replacement species include, but are not limited to: Elymus lanceolatus (thickspike wheatgrass), Elymus lanceolatus ssp. psammophilus (streambank wheatgrass), Elymus trachycaulus ssp. trachycaulus (slender wheatgrass), Achnatherum hymenoides (Indian ricegrass), Poa canbyi, Stipa viridula (Green needlegrass). For any introduced species that are requested, BRT will need to address the requirements of Rule 4.15.2(3) to demonstrate the introduced species are desirable and necessary to achieve the approved post mining land use of rangeland and wildlife habitat. 10. There is no evidence in the permit documenting the Division of Wildlife (DOW) consultation and concurrence regarding the woody plant density standard. Page 2.05-56 says that, "since the intent of the revegetation plan is to balance the grass forage
