CARB Approved IOM 12 - ARID Permeator AT-150 - VR-201-Z /VR-202-Z Commissioning and Start-up of PERMEATOR on site Start-up testing for a GDF that has the Permeator AT-150 installed on it must be tested in accordance with the test procedures outlined in the CARB Executive Order VR-202 series (starting with Revision Y). These tests are listed below: TP-201.3 (Leak Decay) Exhibit 8 (Items to Consider when Conducting TP-201.3) TP-201.4 (Dynamic Back Pressure—if applicable) See Note Below Exhibit 5 (V/L of Model 900 Nozzle) Exhibit 9 (Veeder-Root ISD Operability Test) Exhibit 11 (Liquid Condensate Trap Compliance—if applicable) Exhibit 14 (Dispenser Integrity) Exhibit 15 (Permeator Compliance) Note: TP-201.4, Dynamic Back Pressure (July 3, 2002), is primarily conducted at new GDF installations prior to backfill. If required by the District, it shall be conducted in accordance with the conditions listed in item 1 of the Vapor Recovery Piping Configurations Section of Exhibit 2. Districts have the authority to require conducting of Exhibit 5, Vapor to Liquid Volume Ratio, in lieu of TP-201.4, provided that at least two gallons of product are introduced into the system through each dispenser riser prior to conducting the test. Liquid Leak Integrity Testing EPA approved and third-party tested liquid leak technologies should be applied to new and existing sites before the PERMEATOR system is started up and commissioned. The application of such protocols will ensure that the liquid piping and tankage is leak free. The choice of a test protocol lies with the local installation contractor. Pressure Control Set Points In automatic control mode, the vacuum pump is actuated when the upper control limit (P hi) of 0.30± 0.06"W.C. is reached by the measured variable—the underground storage tank pressure. On the plc (B, Figure 2), the Motor status box on the lower right side will indicate ON. At the same time, the minimum run timer will ensure operation for at least the factory pre-set minimum run time. If the tank pressure is reduced to the Lower Control Limit(P lo) of 0.20 10.06"W.C. before the minimum run time period has elapsed, the vacuum pump will continue to operate. At any time after this 40-minute interval, when the storage tank pressure reaches the low pressure set point, the vacuum pump will shut off. Note: If the tank pressure drops below zero (negative pressure) at any point during the 40-minute run interval (as measured by the PERMEATOR pressure sensor), the PERMEATOR will shut off to limit electricity usage and unnecessary run time for the system. 12
