After backfilling to top of turbine enclosure: • Place 1 1/4" of specified gravel and then 3/4" thick plywood (4'x4") over top (but not over oval lid) to allow a 2" minimum clearance between top of turbine enclosure and bottom of concrete pad. ❑ This 2" clearance also provides a channel for water runoff. ❑ See section F10 for more details. If the tank is located in traffic area: • Pour 9" thick traffic slab with extra rebar reinforcement directly onto plywood. • After sealable turbine enclosure is installed. ❑ Use a minimum 36" diameter (or 36" square) street box to allow room to remove oval lid after it is installed. F12. Monitoring CAUTION: Secondary containment collar must be continuously monitored for potential spills or leaks. To detect accumulation of liquid in collar: • Equip all secondary containment collars - at the jobsite - with an optional electronic monitor. • Place monitoring sensor in a protective casing. • Fasten casing to sensor mounting bracket on side of turbine enclosure using a mounting clamp.

If collar sensor detects product in the containment collar, disconnect power to submersible pump by: • Providing an electrical feedback circuit from the monitoring system to disengage submersible pump. See section D4, Transmission Contact Switch for optional Owens-Corning Control Panel. Note: Test the containment collar sensor at least once a year. F13. Traffic Slab • Traffic areas require a rebar reinforced concrete road surface to span the underground void created by turbine enclosure (see section 1710). Fuel Vapors May Be Present in the AWARNING Turbine Enclosure. To Prevent Fire or Explosion Hazard, Keep All rgnition Sources Away When Removing Turbine Enclosure Lid. Treat Any Entry Into Turbine Enclosure Area as Confined Space Entry. F14. Maintenance • Use caution for normal maintenance or inspection of submersible pump and piping located in turbine enclosure. F15. Future Periodic Testing If turbine enclosure has been abused, damaged, or worn: • Test turbine enclosure immediately for potential leaks. In normal service: • Use standing water test as described in F7. Note: Leak test turbine enclosure at least once a year. ment Collar Manway Containment Collar Sensor (CCS) Containment Collar Sensor (Model CCS) Lead Wire (72" Min.) f r— Trip Rod Hose Clamp Float Switch Perforated Plastic Casing a o 24 Containment Collar Sensor Model CCS: For continuous electronic monitoring or secondary containment collar, Owens-Corning can provide a containment collar sensor which: • Consists of a float switch (normally closed) housed in a protective plastic casing. ❑ Float switch is activated after a 1" accumulation of liquid in collar (approximately one gallon of liquid when placed at lowest point in containment collar). • Features a trip rod, which is used to test float switch in installed condition. • Is compatible with optional electronic control panels supplied by Owens -Coming. ❑ All electrical components for the collar sensor are U.L. listed.
