Also, provide the <br /> proposed drop tube calculations for the overfill flapper valves. <br /> 2) Drawing FS-6, please clarify concrete thickness around the under dispenser containments <br /> (UDCs). <br /> 3) On your sheets please identify the minimum pea gravel thickness to be installed between tank <br /> sumps and the concrete to prevent load transfer to the top of the tank(s). <br /> 4) Drawings FS-3, FS-4, FS-5 show that brine sump sensor reservoir will be mounted onto the sump <br /> wall. Per the submitted sump cut sheets, these sumps have built-in brine reservoirs and not the <br /> external sump reservoirs. Please clarify how these brine sensors will be installed inside STP <br /> sumps. <br /> 5) Drawing FS-6 identifies that a sump sensor port will be located at the top of the UDC, however, <br /> per the submitted Bravo cut sheet the brine sensor port connection is located at the bottom of the <br /> UDC, please clarify how UDC brine sensors will be installed and how brine communication will be <br /> verified inside the proposed UDC sumps. Please revise and resubmit. <br /> 6) On the revised drawings (for example FS-3 and FS4) it's unclear if the proposed sumps are VPH <br /> compliant, for example, no VPH shroud boots and clamps are illustrated or identified (refer to the <br /> attached illustration). Per the EHD permit application (page 4), "detail of sumps and under- <br /> dispenser containment to demonstrate vapor tightness" and "detail of system that demonstrates it <br /> is impervious to water intrusion" must be provided. Please revise and resubmit. <br /> 7) Drawing FS-7 (diagram 2) indicates that vent sump penetrations will be factory installed (3" <br /> fiberglass cuff entry (factory installed)"for the proposed 2"vent line. Also, no means to verify brine <br /> communication (like a sight glass) was illustrated on the proposed drawings for the vent sump. <br /> Please revise and resubmit. <br /> 8) On the revised drawing FS-12 (received on 11-8-2017) vapor recovery line leading to the 91 STP <br /> was removed. Please revise all respective sheets where it's shown (for example FS-1, FS-3, etc.), <br /> Please revise and resubmit. <br /> Page I of 2 1490 S main Street, Manteca, CA C00076222 <br /> 9171 9690 0935 0151 6824 59 <br />
