• face of the embaal®ent will be stabilized against erosion with <br />vegetation, gravel, or by other means if necessary. Areas in which <br />the vegetation is not successful or where rills and gullies develop <br />rill be repaired and revegetated in accordance with Bule 4.14.6. <br />Discharge from surface facilities rill be controlled by the use <br />of energy dissipating and flow check devices where necessary. Hater <br />released from aedis~entation ponds will travel through spillraya lined <br />with rip-rap, gravel or natural vegetation before being discharged <br />into streams. Surge ponds at discharge points will not be necessary <br />to handle the law discharge rates to be eapected from the design <br />event. Erosion downstream from the proposed impoundments will be <br /> minimized, due to the fact that the ponds are designed to detain <br />• <br /> runoff from flood events and peak flor is routed through the pond in <br />order to reduce the discharge rate and provide time for aettliag of of <br />suspended solids to occur. <br />As documented in Eahibit 3, Sediment Control plan, none of the <br />proposed ponds has a capacity of more than 1,000 acre-feet, <br />embanl®enta greater than 10 feet in vertical height, or surface areas <br />greater than 20 acres. Therefore, requirements of the State Engineer <br />for aediaentation control reserviors do not apply to the ponds <br />proposed in this application. In addition, the ponds do not meet the <br />embaalment height and storage criteria of 30 CFB 77.216; therefore, <br />requirements of the nine Safety and.Health Administration da not apply <br />• to the ponds proposed in this application. <br />2.05 - 24 <br />
