The California Air Resources Board (CARB) is mandating a new low-permeability hose standard for vac-assist vapor recovery systems. This standard is based on research conducted by CARB on gasoline permeability through hose material. From these studies, it is estimated that hoses release approximately 75-100 grams/m/day. At full implementation, it is expected to reduce gasoline vapor emissions by more than 350 tons/year.
To comply you must only use certified replacement hoses starting July 1, 2015. All hoses at your facility must be replaced with hoses certified to the new standard by September 24, 2018. The following hoses are certified:
· Futura HVR Low Perm Hose, manufactured by Veyance Technologies, Inc.
· Healy Model 75 Low Perm Hose, Manufactured by Franklin Fueling Systems
Please, be sure any contractor you use for repairs is aware of this prior to conducting work on your equipment.
There are pending hose permeability standards for non-vapor recovery sites. We will make sure to post information as it becomes available.
The changes do not apply to operators of balance EVR systems at this time, such as VST equipment, however new regulations will undoubtedly be coming in the future for this type of system. We have attached the advisory notice, also available at www.arb.ca.gov/vapor/advisories/advisories.htm , if you would like more information. Please contact us at AQCS Environmental.
