Monitoring Plans for Evaluation of Hydrologic Consequences - OMI currently maintains, and <br />• will continue, a comprehensive program to monitor surface and groundwater quality and quantity for <br />the duration of the proposed mining and reclamation operations. The momtonng program serves as <br />an integral part of OMI's efforts to protect the hydrologic balance by providing an accurate and timely <br />method of identifying and quantifying anypossible concerns with respect to surface and ground water <br />resources. <br />The hydrologic monitoring plan provides for a frequency and distribution of both baseline and <br />operational monitoring data collection adequate to identify and document baseline conditions and <br />trends and fluctuations in the quantity and quality of surface water, the level and quality of grotmd <br />water, and the overall effects of mining and reclamation activities on the hydrologic balance. Water <br />quality parameters include field measurements for pH, specific conductance, and temperature and <br />laboratory measurements for general water quality characteristics such as TSB, TDB, major ions, and <br />selected trace metals. Both surface and ground water quality samples are collected, labeled and <br />transported to a qualified analytical laboratory for analyses. Proper sample collection, preservation, <br />handling, and storage methods will be utilized at all times to preserve the integrity of the samples and <br />assure the validity of the analytical results. The monitoring data and resulting evaluations are used to <br />identify any potential problems and develop any necessary supplemental mitigation measures in a <br />timely manner. <br />The baseline hydrologic information presented in Section 2.04.7, Hydrologic Description, of this <br />permit application includes identification of surface drainages and general flow characteristics; <br />information on corresponding peak flows and annual runoff volumes; identification of ground water <br />aquifers; and a general description of aquifer characteristics including ground water levek, <br />movements, and recharge/discharge/storage characteristics. The baseline hydrologic information <br />forms the base and serves as a reference for the ongoing hydrologic monitoring program The <br />operational monitoring network consists of 2 spring/seep locations, 8 ground water wells, 2 mine <br />water discharges, and 12 stream locations s ,.,,,.,~„~Pd as follows: <br />Site Designation Site Description <br />Borings/Seems <br />SP-8 Oliver Spring <br />SP-9 Lower Spring <br />Grotmd Water Wells <br />Well SG 1 <br />Well SG3 <br />Well EG7 <br />Well B-6 <br />Well BG 1 <br />Well H-10 <br />Well EG14 <br />_ Well EG 15 <br />Mine Water Discharge <br />Outfall 011 <br />Chrtfall 015 <br />Streams <br />Site G 1 <br />Site HN-1. <br />Site S-1 <br />Site S-2 <br />Site E-1 <br />Site E-2 <br />Rollins SS -Sanborn Geek <br />D-Seam-Sanborn Geek <br />Alluviutn/Colluvium -Elk Geek <br />B-Seam - Upper Beaz Geek <br />Alluviutn/Cnlluvium - Beaz Geek <br />B-Seam -Upper Hubbard Geek <br />Alluviutn/Colluvitun -Elk Geek <br />Alluvium/Colluvium -Elk Geek <br />Sanborn Geek Mute Discharge <br />Elk Geek Mine Discharge <br />Coal Gulch <br />Lower Hawks Nest Geek <br />Upper Sanborn Geek <br />Lower Sanborn Geek <br />Lower Elk Geek <br />Upper Elk Geek <br />
