I <br /> Flying J Travel Plaza #618, 1501 N. Jack Tone Rd., Ripon CA, 95366 — SR0068444 <br /> First response received: Refer to detail O1/PP1.1 Vent Cluster detail. Vent rack <br /> transition sump and monitoring requirements are shown in this detail. <br /> After reviewing sheet PP1.1, detail 01, a transition sump and monitoring details were not <br /> shown that meet the requirements. The proposed Ameron LCX coaxial 3" over 2" <br /> fiberglass vent piping needs to be continuously monitored by vacuum, pressure or <br /> hydrostatic as listed in the CA Health and Safety Code (HSC) section 25290.1(d). The <br /> transition from double wall fiberglass to black iron occurs below finished grade near the <br /> vent rack. Please provide information on how the continuous monitoring for the vent <br /> piping will be installed for this below grade transition area. <br /> Second response received: Specified 3" Ameron LCX Coaxial vent pipe is <br /> hydrostatically monitored. Specified sump is double wall hydrostatically monitored. <br /> Specified sump sensor is a non-discriminating sensor programmed for positive shut <br /> down when in alarm. <br /> Submit a revised sheet PP1.1, section 1 —"Vent Cluster Detail" that includes the double <br /> walled vent transition containment sump, including model number, the continuous <br /> monitoring, including model numbers, and the 3" Coaxial vent piping being utilized. The <br /> date on sheet PP1.1 that was submitted is from 9-25-13. 1 have included a portion of the <br /> sheet that was submitted which does not illustrate a vent sump. <br /> Sheet PP2, section 2 —"20,000 Gallon Bio-Diesel Tank Section" illustrates 3°size over <br /> 2°size vent piping, not 3° coaxial piping. Also continuous monitoring for the vent piping <br /> is not illustrated. Submit a revised sheet PP2, section 2 that illustrates the required <br /> items listed above. <br /> Sheet PP3, section 3 —"Bio-Diesel Tank Fill/Vent Manway" illustrates 3"size over 2"size <br /> vent piping, not 3" coaxial piping. Also continuous monitoring for the vent piping is not <br /> illustrated. Submit a revised sheet PP3, section 3 that illustrates the required items <br /> listed above. <br /> 3. The plans do not include continuous monitoring for the secondary containment of the <br /> product, vent, and vapor piping (vacuum, pressure, hydrostatic). Explain how the plans <br /> will comply with Chapter 6.7 of HSC. S <br /> First response received: System is hydrostatic monitored. Refer to the following details <br /> for continuous monitoring illustrations and equipment: 011PP1.1, O1/PP3, 02/PP3, <br /> 011PP5, 021PP5. <br /> y <br /> Upon reviewing the listed sheets it was found that a Bravo Manometer Brine Hydrostatic <br /> Reservoir with a Veeder Root sensor will be utilized with brine filled Ameron Coaxial <br /> LCX 2 inch fiberglass piping. A cut sheet was not provided for this piping-, therefore a <br /> determination cannot be made as to which model number is proposed to be installed. <br /> According to the CA State Water Resources Control Board, in the Local Guidance Letter <br /> (LG) 113, acceptable hydrostatic monitoring methods, Ameron Dualoy 3000/LCX for <br /> pressurized primary piping is only allowed to be hydrostatically monitored by pressure. <br /> Also the total length existing product piping is greater than the maximum length of 344 <br /> feet. Please provide information for how the continuous monitoring for the new piping <br /> 2 <br /> gs <br />
