Macias <br />Roy W. Pedro 1. Double wall under dispenser containment installation Guide and Maintenance <br />Alan K. Shimabukuro Instructions for listed products. <br />John W. Strobel 2. Testing and Monitoring Instructions for the listed products. <br />3. Double wall containment dispenser illustrations. <br />Blythe R. Wilson 4. Illustrations and drawings of B -17-D and B -33-D Flexible Double Penetration Fittings <br />that interconnect with the interstitial space of the double wall dispenser containment <br />and are tested with the interstitial space of the dispenser sump. <br />5. A section removed from a double wall dispenser containment for inspection of the <br />construction and for determination of the volume of the interstitial space. <br />6. Bravo standard Dispenser Containment water testing instructions dated 9127/01. This is <br />an alternate for non -double wall dispenser containment. <br />7. Material Data Sheet for interstitial fluid used for continuous monitoring of the Bravo <br />LIDS interstitial space. <br />8. The sensor for monitoring the interstitial space is furnished by others. <br />9. Chemical compatibility data for Dion ISO 6631 <br />10. Chemical compatibility for Derakane 411 <br />11. UL letter with test record dated 9/12104 on annulus proof pressure/vacuum test. <br />Upon review the materials and construction it is my opinion and conclusion that sound <br />engineering design and engineering of these products provide an in-place system that will <br />provide the required secondary containment and allow continuous vacuum or hydrostatic <br />Offices monitoring of the containment interstitial space including the sump penetration fittings. <br />ANAHEIM, CA <br />BELLEVUE, WA <br />CAMAS, WA James H.
