AST systems constructed of metal and installed in contact with an electrolyte must be cathodically protected with sacrificial anodes or an impressed current system which is designed, fabricated, and installed in accordance with a code of practice developed by nationally recognized associations or independent testing laboratories such as NACE Standard RP-02-85 (1985), API Standard 1632 (1983), or similar methods approved by the department.</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; New AST systems containing noncorrosive substances do not require internal coatings. Monitoring of the pH of the tank condensate is required biannually, not to exceed 7 1/2 months between sampling. A pH of 6.8 or higher shall be maintained. Owners or operators of an AST which cannot comply with this section may request a variance from the department by submitting justification for the variance. Criteria for granting the variance are the same as those listed in §&nbsp;74:56:03:06.</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 76, effective November 29, 1987; 18 SDR 62, effective October 10, 1991; transferred from §&nbsp;74:03:30:07, July 1, 1996.</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=34A-2-93">34A-2-93</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=34A-2-101">34A-2-101.</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=34A-2-100">34A-2-100</A>, <A HREF="/statutes/DisplayStatute.aspx?Type=Statute&Statute=34A-2-101">34A-2-101.</A></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>References:</b> UL 142, 1985 Edition, Underwriters Laboratory, Inc.
