8) STP sump details (G4.0 and G4.1) do not show any proposed smart sensors or vacuum <br /> communication ports or vacuum hoses. All proposed vacuum supply and communication <br /> components to be installed must be identified on proposed drawings. <br /> 9) Per your response #17 all piping cross overs will be a minimum of 12 inches, please <br /> confirm that such cross over distance will be maintained through the entire piping layout. <br /> 10) Drawing G7.1, Fe Petro leak detector is listed under VMI schedule and Phil-Tite <br /> components are listed under OPW schedule, please correct as appropriate. <br /> 11) Drawing G12.1, all vacuum zone terminations must be shown for all piping inside under <br /> dispenser containments (UDCs), identify all provisions for communication testing at each <br /> vacuum zone termination (UDCs, sumps, vent sumps, chase piping, etc.), provide a <br /> legend for any symbols (like valves) being utilized. On this drawing several vacuum <br /> hoses terminate without any apparent valves or penetrations they should be going <br /> through. Drawing G5.0 doesn't depict vacuum communication provisions for UDCs or <br /> piping. Also, it is EHD's understanding that Phill-Tite spill containers are proposed, <br /> however OPW spill containers are included on this drawing (OPW spill containers are <br /> also shown on G4.1 and several other drawings), please clarify and correct as <br /> appropriate. <br /> 12)Vacuum zone volumes were requested previously, please clarify where they were <br /> included in this revised submittal. G6.2 lists 3 vacuum zones, however, 9 smart sensors <br /> are shown on G12.1, please clarify. <br /> 13) Provide the following certifications: INCON for Byron Molina, a current Xerxes <br /> certification for all tank installers (the submitted certification has a typed in expiration <br /> date), certifications for all proposed flex connectors (Unisource, Fireflex and Flexing), <br /> Phil Tite, Franklin Fueling Defender Series, and Fe Petro for leak detectors. <br /> 14) Provide all computability documentation and UL /third party listing information (see <br /> attached compatibility requirement guidance letter dated January 2019 for more <br /> information) <br /> If you have any questions, don't hesitate to call me at (209) 953-7699. <br /> Thank you, <br /> Elena Manzo, Sr. RENS <br /> Lead Sr. Registered Environmental Health Specialist <br /> Page 2 of 2 141 E Harney Ln., Lodi CA SR0079417 <br />
