• quality deviations from the multiple-year ranges not explainable by climatic fluctuations will be <br />considered to suggest impacts from mining. <br />7. Surface Water Monitoring Plan <br />introduction. The following section summarizes how future mining impacts on both surface water <br />quality and quantity will be evaluated using monitoring data collected at sites established in the <br />New Horizon 2 mining area. <br />Surface Water Quality. Future impacts on surface water quality will be evaluated by using <br />trending analyses. Mining activities at the New Horizon 1 Area began prior to the onset of <br />collecting surface water quality data (1979), hence, no true baseline data exists for comparison <br />purposes. However, a well documented but short record of surface water quality has been <br />collected during baseline studies conducted at the New Horizon 2 area. Regardless, the <br />significance of impacts will be evaluated by analyzing for prominent trends of changing chemical <br />concentrations over time. Consistently increasing concentrations of chemical parameters will be <br />considered to suggest mining impacts. Data collected at sites located above mining (most <br />upstream) along Calamity Draw (proposed surface water monitoring site) will be used for <br />• investigating whether any future observed trends are natural or result from mining. <br />Surface Water Quantity. Trending analysis, as mentioned in the previous section, will be used <br />to evaluate mining impacts on surface water quantity. Consistent increases or decreases inflow <br />over time at surface water monitoring sites will suggest mining impacts. Should trending analysis <br />of flow data suggest impacts from mining, W FC will consider more frequent flow monitoring and <br />further investigation to define whether trends reflect natural or non-mining causes (irrigation) as <br />opposed to mining impacts. <br />• <br />(Revised July 2006) 2.05.6(3)(b)(v)-8 <br />
