• desirable species, will be used for revegeta tion. <br />The impact of the stream buffer disturbance on the hydrologic balance should be <br />negligible. The disturbance area is minimal and does not affect the main channel. Haul <br />road ditches are properly designed. Salvaged topsoil will be replaced and a seed mix <br />containing native species will be used to revegetate the disturbance area when it is <br />reclaimed. <br />Water Rights and Alternative Water Suo of ies <br />Introduction. Surface and ground water rights, as well as unsighted water sources within <br />and proximate to the Seneca II-W Mine have been investigated with regard to Peabody's <br />proposed operation of the Seneca II-M! Nine. Table 16-1 provides information such as <br />location, decreed amounts and adjudication dates for the investigated water rights. <br />Exhibit 16-1 depicts the locations of these water rights and unsighted water sources. <br />Peabody has secured three water rights that will ensure sufficient water during the life <br />• of mining for domestic, industrial, and augmentation purposes: 1) Peabody Seneca II-W <br />( <br /> Mine Pond 006; 2) Peabody Seneca II-W Well No. 1; and 3) Peabody Pon d Y-1. Appendix 16-1 \ <br /> contains the "Referee's Ruling" documents for all three rights. This appendix also <br /> contains a copy of the well permit issued by the State Engineers Office for Peabody's <br /> Seneca II-W Well No. 1. <br />Water Rights Studies and Analyses. A detailed study of water rights in the vicinity of <br />the Seneca II-W Mine was completed by the engineering consulting firm of Tipton and <br />Kalmbach, Inc. in May of 1989. The final report, titled "Water Rights Investigation and <br />Plan for Augmentation" is presented in this tab as Attachment 16-A. This report also <br />includes information related to plans for augmenting water supplies and rights affected by <br />Peabody's water usage at the Seneca II-W Mine. Attachment 16-8 presents a study conducted <br />by CeoTra ns, Inc. which addressed the long term effects of pumpage from Pea body's supply <br />well (Peabody Seneca II-W Well No.~1) on stream flows in the vicinity of the Seneca II-4! <br />Mine. Results and conclusions generated by both studies were integral to the plan for <br />augmentation that was approved by the State of Colorado (Office of the State Engineer, <br />Division of Water Resources). <br />• Tab 17, Probable Hydrologic Consequences, presents detailed analyses of the effects from <br />8 <br />
