APPENDIX P <br />Discharge from Sediment Ponds <br />The three sediment ponds at the Fruita Loadout Facility have been designed to retain water from <br />100 -year precipitation events from runoff within the facility, including the portion of railroad <br />spur inside the facility east of Reed Wash but not from the railroad spur west of Reed Wash. <br />There is no surface connectivity between the swales discussed above and the sediment ponds <br />because they are separated by Reed Wash. As noted in the BA, sediment would be removed <br />from all ponds when the ponds are 75 percent full of sediment. <br />Conservation Measure #4 states that water held in sediment ponds within the Loadout Facility <br />shall be pumped and removed to an approved disposal facility instead of discharged directly into <br />Reed Wash. It is reasonable to assume that water would be pumped and removed in the spring <br />with runoff from melting snow and again in the summer"during the monsoon season. The pond§ - <br />would be lined so any water lost between discharges would be through evaporation. <br />Thank you and your staff for the coordinated effort. Please feel free to contact me at <br />dpaculaO—osmre.gov or (303) 293-5044 regarding any questions concerning this addendum. <br />Sincerely, <br />Dawn S.
