A gasoline dispensing facility is a stationary facility that contains a storage tank, usually an underground storage tank, from which gasoline is transferred to motor vehicle fuel tanks.
These facilities employ the use of Stage I and Stage II vapor recovery systems designed to control the emission of gasoline vapors during transfers.
The final-form rulemaking also adds and amends definitions related to Stage I and Stage II vapor recovery systems. A copy of the final preamble and regulation can be accessed here.
The Pennsylvania Department of Environmental Protection (DEP) has finalized regulatory requirements for GDF owners and operators to decommission their Stage II vapor recovery system in 12 counties in the Philadelphia and Pittsburgh areas. The compliance date for the decommissioning of Stage II systems is December 31, 2022.
“Stage I” refers to a vapor recovery system that controls the emission of gasoline vapors into the atmosphere during the transfer of gas from a gasoline tank truck to a gasoline storage tank at a Gasoline Dispensing Facility (GDF). A properly operating Stage I vapor recovery system returns vapors to the gasoline tank truck. The equipment and controls of a Stage I system also control the emission of gasoline vapors during the storage of gasoline vapors at a GDF.
“Stage II” refers to the vapor recovery system that controls the emission of vapors during the transfer of gasoline from a gasoline storage tank at a GDF to a motor vehicle fuel tank. A Stage II vapor recovery system also controls emissions into the the atmosphere of vapors during the storage of gasoline at a GDF. Stage II vapor recovery technology uses special refueling nozzles, dispensing hoses and a system that draws refueling vapors in the Underground Storage Tank (UST). A properly operating Stage II system moves the gasoline vapors from the motor vehicle fuel tank druing the refueling of the vehicle into the UST at the GDF.
For those entities that need to decommission their Stage II vapor recovery system by December 31, 2022, a notification form needs to be completed and submitted to the appropriate DEP regional office, Allegheny County Health Department, or Philadelphia Air Management Services.
Effective on August 20, 2022, Pennsylvania DEP suspended the enforcement of a specific monitoring requirement – the inspection of the gasoline storage tank automatic tank gauge (ATG) cap. The reason for the suspension is that after a review of the rule’s requirements it was determined that the likelihood of the ATG being compromised is very low and the verification of the ATG status after every gasoline truck delivery can be problematic and difficult to access.
Please note that the suspension of this specific monitoring requirement does not affect owners or operators of gasoline dispensing facilities relief from other Stage I & Stage II requirements.
