V?, <br />Pond Design Checklist <br />Page 2 <br />Downstream sideslope: 2.5 <br />Upstream sideslope: 2.0 <br />Total 4.5 <br />The applicant's safety factor analysis in the submittal demonstrates the embankment will be <br />stable; therefore, as allowed by 4.05.9(7)(e), the combined side slopes steeper than 5:1 are <br />allowed. <br />7. Is either embankment slope steeper than 2:1? <br />No. <br />8. Will faces of embankments and surrounding disturbed areas be vegetated or otherwise <br />stabilized? <br />Yes. <br />9. Is erosion control provided for below the spillway? <br />No spillway. The design provides rock or other flow dissipation downhill from dewatering <br />outfall. <br />10. Calculate the permissible inlet velocity using Fr = V/ (see page 3.44 of Design Manual for <br />Sediment Control, 1982) <br />N/A (mine water treatement pond, not for surface runoff sediment control) <br />11. Calculate permissible flow-through velocity, vsc = (see page 3.44 of Design Manual for <br />Sediment Control, 1982). <br />N/A (mine water treatement pond, not for surface runoff sediment control) <br />12. Will 10-yr., 24-hr. discharge meet TSS limitations of 50 ml/1 ? <br />N/A (mine water treatement pond, not for surface runoff sediment control)
