Vapor Recovery Certification and Compliance
Test Procedures Workshop

Dear Sir/Madam:

The California Air Resources Board (CARB) is holding a workshop to solicit public comments on new vapor recovery certification test procedures, modifications of existing certification test procedures, and new vapor recovery test procedures that can be used by the ARB and districts for compliance determination of in-use vapor recovery systems.

The time and place for workshop are as follows:

                               DATE:         Wednesday, June 20, 2001

                               TIME:           9:00 a.m. to 12:00 p.m.

                               PLACE:        Cal/EPA Headquarters Building
                                                     Sierra Room, 2nd Floor
                                                     1001 I Street
                                                     Sacramento, California 95814

Existing certification test procedures proposed for modification include TP-201.4, Determination of Dynamic Pressure Performance of Vapor Recovery Systems of Dispensing Facilities and TP-201.6, Determination of Liquid Removal of Vapor Recovery Systems of Dispensing Facilities. New certification test procedures proposed for adoption include TP-201.1C, Static Torque of Rotatable Phase I adaptors and TP-201.1D, Pressure Integrity of Drop Tube/Drain Valve Assembly. In addition, we are also proposing compliance test procedures that are used for determining compliance with in-use performance standards or specifications.

These draft certification and compliance test procedures can be downloaded from the ARB website at after June 4, 2001. Please call the Engineering and Certification Branch office at (916) 327-0900, if you would like to receive a copy of these test procedures by mail.
