At EPCOR, our #1 priority is safety. We've become aware that some homebuilders and customers may be improperly placing grounding or bonding attachments to EPCOR natural gas meters or other components of the EPCOR gas system.
This practice is unsafe as well as ineffective for electrical grounding – and it has important legal implications.
See details below.
Using EPCOR's natural gas equipment for grounding / bonding is not effective because it doesn't properly ground metal facilities.
This practice also puts people and the natural gas system at risk. It poses a shock hazard to homebuilders, EPCOR employees and customers and threatens the integrity of EPCOR's natural gas facilities by compromising the corrosion control systems that protect piping and other fixtures.
U.S. Department of Transportation Pipeline Safety Regulations require maintaining electrical isolation for the underground natural gas pipeline system from all foreign underground and above-ground metallic structures. Improper grounding on EPCOR facilities also violates standards of the National Fire Protection Association (NFPA) and National Electric Code (NEC):
