Monthly Stage I Vapor Recovery Equipment Monitoring Check List - Additional Guidance
1 The underground storage tank fill tube cap must be completely attached to the fill tube riser in order to provide a tight seal to prevent excess volatile organic compound emissions from escaping to the atmosphere.2 An underground storage tank with a cracked fill tube cap or broken hardware will not seal tightly allowing excess volatile organic compound emissions to escape to the atmosphere.
3 The underground storage tank fill tube cap must have a properly sized gasket in place on the underside of the cap as it is secured to the fill tube riser. Cracked, excessively worn or missing gaskets will not allow the cap to seal tightly allowing excess volatile organic compound emissions to escape to the atmosphere.
A cap and a gasket may both be present on the fill tube riser and it still could not be sealing tightly. Check the seal as follows:
- Remove the fill tube cap and gasket.
- Turn the brass extension on top of the fill tube clockwise to be sure it is secure and not loose.
- Position the fill tube cap and gasket on top of the fill tube and properly attach it.
- Apply hand pressure and turn the fill tube cap. If the properly secured fill tube cap makes a complete revolution while in place, the fill cap is too loose and is not maintaining a tight seal. The fill tube cap and gasket must be repaired or replaced to reinstate a vapor tight seal.
4 Vapor recovery poppet valves must be maintained in good working order. A permitted facility may have a single or multiple vapor recovery poppet valve assemblies available for use on the premises. Each of the separate valves must be maintained in good working order.
Dual point vapor recovery poppet valve inspection procedure.
- Remove the cap and gasket. Check valve for foreign objects keeping it from properly closing.
- Depress valve and release to determine proper alignment and closure. If present, check valve gasket for tears.
Fixed and spring loaded coaxial vapor recovery poppet valves must have a properly attached fill tube cap / gasket and seal tightly.
