For hydrostatic pressures greater than 110 percent of the MAWP, the steam gauge and the safety valve must be removed. The safety valve spring may not be compressed to prevent the valve from opening.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>Source:</b> 23 SDR 139, effective March 5, 1997.</p> <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; <b>General Authority:</b>SDCL <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=34-29A-14.1">34-29A-14.1.</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=34-29A-14.1">34-29A-14.1.</A></p> </div> </body> </html>
