(10)"Remote Vapor Check Valve" means a check valve in the vapor return line but not located in the nozzle.
(11)"Stage II Vapor Recovery" means to the control of gasoline vapor at the vehicle fill-pipe, where the vapors are captured and returned to a vaportight storage tank or are captured and destroyed.

(1)the transfer is made using a Certified Stage II vapor recovery system that meets the requirements of the inspections;
(2)all installed Stage II vapor recovery systems use coaxial vapor recovery hoses; no dual-hose designs shall be used;
(3)all installed Stage II vapor recovery systems used are certified by CARB except that the Stage I system need not be CARB certified. In addition, no Stage II system shall employ a remote vapor check valve. Pressure balanced Stage II systems may be used; and
(4)the underground vapor return piping satisfies the requirements of Rule .0953 of this Subchapter.
In the event that CARB revokes certification of an installed system, the owner or operator of the facility shall have four years to modify his equipment to conform with re-certification requirements unless modifications involve only the replacement of dispenser check valves, hoses, or nozzles or appurtenances to these components in which case the allowed time period is three months.

(1)one year from the date that the Director notices in the North Carolina Register that an area is in violation of the ambient air quality standard for ozone, for facilities having any single monthly throughput of at least 100,000 gallons per month;
(2)two years from the date that the Director notices in the North Carolina Register that an area is in violation of the ambient air quality standard for ozone, for facilities having any single monthly throughput of greater than
10,000 gallons but less than 100,000 gallons;

(A)one year from the date that the Director notices in the North Carolina Register that an area is in violation of the ambient air quality standard for ozone, for 33 percent of affected facilities;

(A)Bay Area Source Test Procedure ST-30, Leak Test Procedure, or San Diego Test Procedure TP-91-1, Pressure Decay/Leak Test Procedure every five years;

(B)Bay Area Source Test Procedure ST-27, Dynamic Back Pressure, or San Diego Test Procedure TP-91-2, Pressure Drop vs Flow/Liquid Blockage Test Procedure every five years; and

(C)Bay Area Source Test Procedure ST-37, Liquid Removal Devices every five years.

If the tests have been performed within the last two years the owner or operator may submit a copy of those tests in lieu of retesting. Testing shall be in accordance with Rule .0912 of this Section.
