Section 096-118-8 - Testing for Stage I and Stage II Vapor Recovery Systems

(1) An owner or operator of a gasoline dispensing facility with a throughput greater than 100,000 gallons per month must perform a PV vent valve test initially and at least every three years thereafter. This test must be performed in accordance with CARB's TP-201.1E: "Leak Rate and Cracking Pressure of Pressure/Vacuum Vent Valves". This test is commonly referred to as the "P/V Cap Test".

(2) An owner or operator of a gasoline dispensing facility with a throughput greater than 100,000 gallons per month must perform a pressure decay test at least every three (3) years. This test must be conducted in accordance with CARB's TP-201.3: "Determination of 2 inch (wc) Static Pressure Performance of Vapor Recovery Systems of Dispensing Facilities".

(3) Reverification of the proper installation and function of the Stage I vapor recovery system as described in Section 8(A) of this Chapter must be performed upon major system replacement or modification, whichever occurs first. Functional tests must also be performed within thirty (30) days upon request by the Department when inspections, records, or other evidence show noncompliance with the regulation. This reverification must include all functional tests that were required for the initial system certification.

(4) The owner or operator must have the tests performed Monday through Friday during normal work hours unless otherwise approved by the Department. The owner or operator shall notify the Department in writing at least five (5) days in advance as to when the testing will occur, and what party will conduct the testing. The Department may observe the test at its discretion.

(5) The owner or operator shall provide a copy of all test results to the Department within thirty (30) days.

(1) Once the Stage II vapor recovery system is in operational condition and ready for use, testing to verify the proper installation and function of the entire system (both infrastructure plumbing and aboveground equipment) must be conducted and passed. Tests must be conducted in accordance with the following test procedures as found in Volume 2 of CARB's - Stationary Source Test Methods, Certification and Test Procedures for Vapor Recovery Systems, April 12, 1996:

(2) The owner or operator shall notify the Department in writing at least five (5) days in advance as to when the testing will occur and what party will conduct the testing. The Department may observe the test at its discretion.

(3) Reverification of the proper installation and function of the Stage II vapor recovery system as described in Section 8(B) of this Chapter must be performed at least every five (5) years or upon major system replacement or modification, whichever occurs first. However, each Stage II system is subject to the requirements in the respective CARB executive order which may require more frequent testing. In either case, each compliance test whether annual or every five years must include CARB's TP-201.1E, "P/V Cap Test". Functional tests shall also be performed within thirty (30) days upon request by the Department when inspections, records, or other evidence show noncompliance with the regulation. This reverification must include a leak check test and all other functional tests that were required for the initial system certification. A major system replacement or modification is considered to be the occurrence of any of the following:
