Erosion control measures must be implemented during all phases of construction, operation, reclamation, and closure. Detailed plans indicating dimensions, location, spacing, and design of erosion control techniques are required;</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (3)&nbsp;&nbsp;All grading, backfilling, and topographic reconstruction must be completed as soon as feasible after mining ceases. The operator shall establish reasonable timetables consistent with good mining and reclamation practices;</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (4)&nbsp;&nbsp;Depressions for the accumulation of water are not allowed unless they are consistent with the approved postmining land use;</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (5)&nbsp;&nbsp;Original drainage must be preserved as much as possible. Alternative drainage may be approved by the board if it is functionally compatible with and complements the prevailing hydrologic balance of the surrounding area;</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (6)&nbsp;&nbsp;When highwall reduction or elimination is not proposed, the applicant must provide justification demonstrating that such reduction or elimination is impossible, impractical, or aesthetically undesirable. If they are not eliminated, all highwalls must be stabilized; and</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (7)&nbsp;&nbsp;Landforms created as the result of grading, backfilling, or topographic reconstruction of the affected land must blend in with and complement the visual continuity of the surrounding area. Mitigation techniques such as land shaping, rock sculpting, or visual screening may be used to minimize negative visual impacts.</font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>Source:</b> 14 SDR 111, effective March 3, 1988.</font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>General Authority:</b> SDCL <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=45-6B-81">45-6B-81.</A></font></p> <p><font size=3 face="Times New Roman">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>Law Implemented:</b> SDCL <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=45-6B-37">45-6B-37</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=45-6B-45">45-6B-45.</A></font></p> <p><font size=3 face="Times New Roman">&nbsp;</font></p> </div> </body> </html>
