Bravo Systems, Inc. <br />2929 Vail Ave. <br />Commerce, CA 90040 <br />JUL 10 2017 <br />Re: Specification approved by a state registered professional engineer <br />CCR Title 23, Division 3, Chapter 16, Article 3, Section 2631(d) <br />Revised 12.09.13 <br />F�,;. I <br />is t7 <br />This letter is for an engineering specification review and approval of a secondary <br />containment system component which is not an integral part of primary containment for an <br />underground fuel tank storage system in California. The authority for this approval comes <br />from the California Code of Regulations (CCR) Title 23, Division 3, Chapter 16, Article 3, <br />Section 2631(d). <br />I have examined and reviewed the following specifications for the B-830 Commercial Series <br />transition sumps: <br />1) UL.com Certification Directory EGVV2.MH26018 for AOC Vipel F-764 and 774 resins <br />2) UL.com Certification Directory Category EGVV2.guideinfo <br />3) UL.com Certification Directory StandardANSWL 1316 <br />4) AOC Vipel Product Selection Guide <br />5) AOC Vipel Corrosion Resistance Resin Guide <br />6) Bravo Systems Sump Wall Specifications document Bravo_ SumpWallConstSpec_2013 <br />7) Bravo Systems datasheet B830 -SW -Commercial and B830 -DW -Commercial <br />8) Bravo Systems datasheet B407 -RB -1313 and B409 -D -AB -13A <br />9) Bravo Systems datasheet SNAP -SERIES -13A <br />10) Bravo Systems installation manuals for the B407 -RB and B409 -D -AB products <br />11) Representative B407 -RB, B409 -D -AB, B833, B834 and B835 transition sumps <br />12) Detailed drawings of B407 -RB, B409 -D -AB, B833, B834 and B835 transition sumps <br />13) Bravo Systems Factory Certificates for both SingleWall and DoubleWall products <br />14) Bravo Systems Alternative Fuel Compatibility letter for containment sumps R3 <br />15) Bravo Systems document Bravo_30Year_CorrosionWarranty <br />16) Bravo Systems UL Approval document UL_BRAVO_B400_SERIES <br />17) State of Florida DEP Approval document FDEP-EQ615-SW-DW <br />The B830 series sumps are four -wall variants of the established UL Listed SingleWall B407 -RB and <br />DoubleWall B409 -D -AB transition sumps, which have octagonal walls. The B830 series was <br />established to allow Bravo's architectural & engineering community to specify the length and height <br />of the containment sump at the time of order to accommodate a wider range of applications. <br />Continued on Page 2... <br />3RP-B830-Commercial-Series PAGE 1 of 2 <br />
