A series of perforated gravity collection pipe, sufficient in number and size and connected to a monitoring pipe or pipes outside of the secondary containment, must be employed in the construction of the secondary containment to detect possible leaks of the secondary containment system. Other methods of leak detection may be utilized to monitor the secondary containment system, if approved by the secretary.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>Source:</b> 15 SDR 194, effective July 1, 1989.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>General Authority:</b> SDCL <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36">38-19-36</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36.1">38-19-36.1</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36.2">38-19-36.2.</A></p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>Law Implemented:</b> SDCL <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36">38-19-36</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36.1">38-19-36.1</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=38-19-36.2">38-19-36.2.</A></p> </div> </body> </html>
