ISD Operability Test Procedures
The following procedures shall be used at field sites to determine the operability of the Veeder-Root ISD system to
satisfy the requirements documented in VAPOR RECOVERY CERTIFICATION PROCEDURE, CP-201,
CERTIFICATION PROCEDURE FOR VAPOR RECOVERY SYSTEMS AT GASOLINE DISPENSING
FACILITIES. Testing the ISD equipment in accordance with this procedure will verify the equipment’s operability
for Vapor Containment Monitoring and Vapor Collection Monitoring.
Veeder-Root’s TLS console ISD System Self-Test Monitoring algorithms are designed to verify proper selection,
setup and operation of the TLS console modules and sensors and will not complete and report passing test results
in the event of a failure of components used in the system. Completed ISD monitoring tests are evidence that:
•
The system was properly powered for data collection
•
All necessary ISD sensors were setup and connected
•
All necessary ISD sensors were operating within specification
•
All internal components including TLS console modules were properly setup and operating within specification
Veeder-Root recommends printing a copy of the ‘ISD Status Events (Monthly)’ and ‘ISD CARB Daily’ reports
periodically to determine that compliance tests are being completed in accordance with local and state
regulations.
