Section 816.461t1 Continued. I• occurs. The methods to be implemented to prevent deterioration of soil during storage are fully described under Section 780.18 and Sections 816.21 of this application. Upon removal of each sedimentation pond, the affected land will be regraded and revegetated as required by 30 CFR 816.100-816.106 and 816.111-816.117 and as described in detail under Section 780.18 of this application. Ponds A, B, D, and E are existing sedimentation ponds. They contain water throughout all or most of the year and typically have some established riparian vegetation. Kerr proposes to retain Ponds A, D, and E as permanent impoundments. These ponds would be used as stock ponds for livestock grazing and would continue to be used as small impoundments for wildlife use and habitat as they have since 1979. Both livestock grazing and wildlife habitat are components of the proposed postmining rangeland use. Pond A was created by constructing an embankment across an existing natural drainage to impound intermittent flows and disturbed area runoff from the southern portion of the . current permit area and adjacent areas. Pond B was created by excavating a depression in an existing ephemeral drainage channel and constructing a low embankment of sufficient size to retain the required volume of runoff from a portion of the disturbed area. Originally this pond did not retain water year-round, however, recently it began retaining sufficient water to support willows within the impoundment basin. Kerr proposes to partially breach the Pond B embankment and allow the area to continue filling with sediment to create a riparian area. Ponds D and E were created by constructing embankments at the outlet of small existing natural impoundments in order to increase the retention capacity for disturbed area runoff. These ponds contain water year-round. 816-61
