Portable Pump A portable wheel mounted water pump will be placed in various locations within the stream buffer zone for Calamity Draw to pump water WFC's decreed water rights from Calamity Draw. Impacts to the stream buffer zone will not occur as the pump will be moved in and out of the stream buffer zone during dry conditions, and the pump will have secondary containment placed under it to capture any leaks or spills that may occur while the pump is located within the stream buffer zone. The pump will only be placed in the stream buffer zone when necessary to exercise valid existing water rights, and will be removed as soon as practical when it is not needed. Tuttle Draw Pond 013 A portion of the Pond 013 embankment, pool area, and associated outfall was constructed inside the stream buffer zone for Tuttle Draw. The embankment and areas directly adjacent to the pond are very well vegetated and do not exhibit any visual impacts from the presence of the pond and associated structures inside the stream buffer zone. In accordance with Rule 4.05.18, the pond location within the buffer zone has not caused or contributed to a violation of applicable water quality standards. As built, the pond is capturing all surface water runoff from mining operations and discharging them through an approved outfall location which is in compliance with New Horizon's mine current water quality discharge permit. Furthermore, during and after mining, the Pond 013 location will not impact water quantity or quality as it will be removed post mining and reclaimed to prime farmland. Finally, Pond 013 does not create a temporary or permanent stream channel diversion. Trench Drain Pipe A trench drain (18" HDPE pipe) to convey spoil spring water from the backfill to the outfall on Pond 013 (see Map 2.05.3(3)-21 for trench drain alignment) has also been constructed within the stream buffer zone for Tuttle Draw directly adjacent to Pond 013. No ground disturbance has occurred within the buffer zone due to the pipe laying on the ground surface, resulting in no adverse impacts to Tuttle Draw. All water from the trench drain will be discharged into an outfall location upstream of the Pond 013 flume. Ditch C-9 Multiple portions of Ditch C-9 were constructed inside the stream buffer zone for Tuttle Draw. During construction and to date, this has not created any adverse impacts to Tuttle Draw. As constructed, Ditch C-9 functions as a collection ditch which captures surface water runoff from the disturbed and reclaimed areas and conveys surface runoff to an approved sediment control structure (Pond 013).
