The operator shall demonstrate that this has been accomplished by conducting a final sampling program that is sufficient to statistically characterize the geochemistry of the tailings, both spacially and temporally, so that a reasonable basis for prediction of future conditions and trends is established. The sampling program may consist of solids sampling, pore water or effluent sampling, or a combination of both or an alternative program approved by the department. Sampling frequency and parameters may be revised during the final sampling program if the department finds that the initial results warrant revision.</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-44">45-6B-44</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>
