Program Permitting and Testing Requirements: 

Initial Inspection and Testing R20-2-905 10 days from beginning operation to submit a Certificate of completion. Test must be witnessed by the Department One difference between the Initial test and the annual is, “Liquid blockage test must be done on all dispensers for the initial test.” Program Permitting and Testing Requirements

Program Permitting and Testing Requirements: 

Modifications to Existing System “Modification” means adding to, replacing, or upgrading a site’s stage II vapor recovery system, but does not include the repair or replacement of like parts. place-in-service Report Required when you Repair or Replace Program Permitting and Testing Requirements

Program Permitting and Testing Requirements: 

Annual Inspection R20-2-910 The same procedures used for the initial test are used for the annual test. Cancellation of an annual test. When canceled one hour before the test, the tester must stay on site until AZDW M Investigator arrives. When canceling a test the day prior to the weekend, use the cancellation form and leave it with the station Program Permitting and Testing Requirements

System Type:

Stage I : 

Stage I Inspection of the Stage I. Dust Cap Dry Break Spill Containment Swivel adaptor

Balance System: 

Balance System

Balance System: 

Balance System Vapor recovery systems passively transfer vapor from an auto's fuel tank to the gasoline dispensing site's underground storage tank . As gasoline fills the auto's tank, vapors are moved out and guided into the underground tank.

G-70-36-AD (OPW Balance system): 

G-70-36-AD (OPW Balance system) System Components Nozzle – OPW 11VS-47 Hose – Standard Coaxial Vapor Recovery Hose Maximum Dispensing rate is 10 GPM.

Balance Dispenser: 

Balance Dispenser System Identification

Vapor and Product Flow: 

Vapor and Product Flow Balance System: Product flow through the vapor path. Hose has external coaxial hose structure.

Balance Nozzle: 

Balance Nozzle Note the function of the nozzle. It has a check valve in it that must be suppressed in order to function. This then allows product to flow through the nozzle.

Pre-test Inspection: 

Pre-test Inspection Need to check the following: Spill buckets Dry Break Vent Caps General condition of the hoses and nozzles.

Vapor Assist Systems: 

Vapor Assist Systems

Vapor Assist System: 

Vapor Assist System Assist systems pull the vapors from the vehicle's tank into the underground storage tank using a pump. The vapor pump may be fluid driven, motor driven, or electronically driven. The pump, or pumps, may be located anywhere along the path from the dispenser to the tank.

Determining when you can run the Short test vs. the long test: 

Determining when you can run the Short test vs. the long test The Following condition must be met to run the short test for Pressure Decay: Average ambient temperature must be below 100 degrees F. They have to be scheduled.

Pressure DecayLong Test: 

Pressure Decay Long Test Testing Requirements Delivery Requirements Ullage Requirement Acceptance Criteria

Pressure DecayShort Test: 

Pressure Decay Short Test Testing Requirements Delivery Requirements Ullage requirements Acceptance Criteria

Pressure Decay Test: 

Pressure Decay Test Procedure 1.Pressure the system to 11 wci 2. Allow it to settle 3. Reduce pressure to 10 wci and start the test. Acceptance Criteria For TP91-1 1wci For TP96-1 See chart.

Pressure Vent Valve: 

Pressure Vent Valve Pressure Vent (PV) Cap The PV Valve is used to regulate pressure in the storage tank. Acceptance Criteria: When using the OPW Leak Check, the valve must hold at 3 pressure and at -8 wci of vacuum.

Liquid Blockage Test: 

Liquid Blockage Test Procedure Add 5 gallon down the furthest point on each island. (Note: on an Initial Test down each, and with a vapor pot 1 gal). Acceptance Criteria 20 CFH allowable 0.15 60 CFH allowable 0.45 100 CFH allowable 0.95

Communication: 

Communication Procedure: 1. Introduce 100 CFH, 20 points higher than than the highest reading on the blockage. 2. Depress the dry break. Acceptance Criteria Once you release the pressure at the dry break, there should be an immediate and significant drop on the gauge - At least 0.1 wci.

Air to Liquid Ratio Test: 

Air to Liquid Ratio Test VacuuSmart Cannot be used for the following systems: Healy 600 and 800 Gilbarco System with the A/L range 0.9 to 1.0 Acceptance Criteria + 0.1
