Related equipment includes valves, meters, and <br />pumping units. Although this dispenser piping and related equipment is aboveground it is <br />part of the underground storage tank (UST) system, and therefore, subject to requirements in <br />Chapter 6.7 of the California Health and Safety Code (H&SC). <br />USTS STORING MOTOR VEHICLE FUEL (MVF) <br />Dispenser piping and related equipment meet the definition of "pipe" in section 25281.5(a) <br />H&SC. Section 25291(a)(7)(E) H&SC requires secondary containment for MVF piping <br />installed after July 1, 1987. Therefore, this piping and related equipment under dispensers <br />must be equipped with secondary dispenser containment if the piping was installed after July <br />1, 1987. <br />• Upgrading MVF systems <br />State rules require dispenser piping installed before July 1, 1987 to be upgraded by <br />December 22, 1998. Corrosion protection for the piping or secondary containment is <br />required by December 22, 1998 if the piping is in direct contact with backfill. <br />Upgrading with corrosion protection or secondary containment under the dispenser is <br />not required if the piping was installed before July 1987 and the piping is not in direct <br />contact with backfill. <br />USTS STORING HAZARDOUS SUBSTANCES OTHER THAN MVF <br />Section 25291(a) H&SC requires secondary containment for non-MVF piping and related <br />equipment installed after January 1, 1984. Therefore, dispenser piping and related <br />equipment under dispensers must be equipped with secondary dispenser containment if the <br />piping was installed after January 1, 1984. <br />• Upgrading non-MVF systems <br />If the UST was installed before January 1, 1984 and stores hazardous substances other <br />than motor vehicle fuel, secondary dispenser containment must be installed by <br />December 22, 1998. <br />Post -it" Fax Note 7671 <br />Date' �; <br />pages <br />To Svc <br />From <br />Go./Dept�G <br />CO. <br />Phone #/`%JC` <br />Phone# <br />Fax # <br />/ " j iG —G": % ✓Fax <br /># � Z,-=. /v> <br />
