during and after wnstruction have not been shown to be problematic. LII2C': See UERC. SW-5: Monitoring of SW-5 should continue as rewired. = is ma/i: suirarp = SW-1, 2': Sites SW-1 aryl SW-2 should be dropped fran the monitoring program as no mining impacts can reasonably be anticipated at either of these locations. Full suite analyses of these sites were condlrc~.ed and included Qtloride = 1 ma/l; SU1Tate = Sf3 m4/l. SW-2 auoriae = « m4/l; SUlydLe = 4~/ Ilq/1 (copies enclosed). No minims has occurred to date which would effect either of these sites and a sufficient database exists to define pre- ntining conditions at these locations. SW-4': SW-4 should be dropped from the monitoring network as no mine impacts can reasonably be expected to develop in this warasshed. A sufficient water quality database exists to charactasize the pre-mining oorditions at this location. Additional data for c~axative purposes can be obtained if nenessaTy in the future. SW-7, 8': Stations SW-7 and SW-8 are located in ephemeral channels subject to sporadic flow events. Zese stations apparently had crest gage installations at one time but the crest gages are currently washed out. Monitoring efforts at these sites should either be intensified to provide meaningful data in the event the Fast mine becotres active again or eliminated as the current monitoring is of little value. SW-102: Station SW-10 monitors flows just belay the headgate of the Terror Ditch. No mining which has occurred to date can reasonably be anticipated to affect the flaws at this location. This site lies off the permit area aryl receives the majority of its flow from the Overland Reservoir via the Fast Fork of Terror Creek. A sufficient database exists to define pre-mining conditions at this site. No further monitoring should be required here until such time as the Fast mine becanes active. Chloride and Sulfate SW-12': SW-12 monitors irrigation water conveyed through the Roberts Stucker Ditch. Water has been conveyed through West Roatcap Creek to this location since 1987. No adverse i~acts to water quantity have become evident since the point of diversion from the Overland Ditch was changed to West Roatcap GYeeJc. No ow~unents or concerns from water right owners have been voiced with regard to the quantity of water being delivered via the new route. thloride and Sulfate analyses were conducted at this location but were omitted from the AHR (copies enclosedl. Further monitorirg of this location should be discontinued after consultation with the affected water users. 16
