-2a- <br />Three alluvial monitoring wells have been installed in the North Fork alluvium in <br />order to rronitor water levels and water quality both above and below the location of <br />the proposed coal stockpile and the sediment pond at the Bear No. 3 mine (see Mine <br />No. 3 - Hydrology Map). One quarter's baseline data for water table depth and water <br />quality has been obtained for the alluvial aquifer (see the above map and "Alluvial <br />Ground water Hydrology of the North Fork of the Gunnison River - Bear No. 3 <br />Operation"). The wells will be monitored quarterly for all of the pararrnters listed <br />in Appendix A of the P.R.R. of May 15, 1981. <br />The potential impacts discussed above are considered insignificant, and the appli- <br />cant's proposed ground water and surface monitoring program will detect any changes <br />in the quantity and quality of ground and surface water supplied to alluvial valley <br />floors downstream. <br />3. Pursuant to Rule 2.06.8(5)(a)(iii), the Division finds that surface coal mining <br />and reclamation operations will be conducted to preserve, throughout the mining and <br />reclamation process, the essential hydrologic functions of the alluvial valley floor. <br />The previous discussion (AVF Finding No. 2) identified no potentially significant <br />impact to the AVF. The monitoring plan, as outlined in the application, will ensure <br />that the essential hydrologic functions are maintained. <br />
