Mountain House Pkwy. Good Afternoon, The San Joaquin County Environmental Health Department(EHD) has completed the review of the underground storage tank installation application for 19533 S. Mountain House Pkwy., Mountain House (SR0083832). Please provide the following additional information and address the following comments: 1. Page 3 of the Application for Underground Storage Tank(UST) Installation Permit(application): Contractor information and Fire Permit information were not included. 2. Page 3 of the application:the certification statement regarding worker's compensation laws of California was not signed by the owner or contractor. 3. Page 6 of the application:the tank capacity for each product does not match the information in the plans. 4. Page 7 of the application and the overfill prevention device cut sheet indicate the overfill prevention device is OPW model 7150,which is non-testable.The plans state the overfill prevention device is OPW model 71SO- 410CT,which is testable. Clarify which overfill prevention device model will be used and provide an updated application, parts list, plans and/or cut sheets. 5. Page 8 of the application:the alarm panel model listed is for a sensor. Update the application with the correct alarm panel model. 6. Plans page FT-1 indicate the burial depth is 5-7 feet. Page FT-1, Item#12 of the UST Anchoring Notes, states tanks will be installed so that the top of the tanks are at the same height.The buoyancy calculations state the tank burial depths are different. Update the plans and/or buoyancy calculations to indicate the accurate tank burial depth information. 7. Plans page FT-1, Item#13 of the UST Installation Notes, states the sump monitoring sensor is to rest on the tank rib. Drawings on Pages FT-2—3 show the submersible turbine pump (STP) and fill sump sensors resting on the tank ribs. Update the plans so that the sensors are installed/maintained/located to detect leaks at the earliest opportunity. 8. Plans page FT-7 shows two product pipes connected to each of the three STP sumps. Plans page FT-2 shows one product pipe connected to each STP sump. Update page FT-7, FT-2, and/or the parts list to indicate the accurate number of product pipes connect to each STP sump. 9. Plans state all sumps are brine-filled.The vacuum zones on plans page FT-7 include STP,fill,vent, and dispenser sumps. Page FT-7 does not show any vacuum lines to the sumps. Clarify which components are brine-vs. vacuum-monitored, and update the vacuum zones on page FT-7 of the plans. 10. Plans do not indicate brine test ports in the STP,fill, and vent sumps. Provide an indication of brine test ports in the STP, fill, and vent sumps. 11. Plans do not indicate that the spill containers have shroud boots and clamps. Provide an indication that the spill containers have shroud boots and clamps. 12. Plans indicate ball valves will be placed on vacuum tubing. No additional shut off valves should be installed between the monitored interstitial spaces and their respective sensors. 13. Plans do not indicate longest piping run. Provide an indication of the longest piping run. 14. A cut sheet for Veeder-Root 304 sensor was included.The Veeder-Root 304 sensor was not included in the parts list or scope of work. Clarify whether Veeder-Root 304 sensor will be used and provide an updated application, parts list, and/or cut sheets. 15. The parts list states the dispenser model is Bravo model B9250.The dispenser cut sheet provided is for Bravo model B9000. Clarify which dispenser model will be used and provide an updated application, parts list, and/or cut sheets. 13
