"Gas infrastructure replacement" means the proposed replacement of any nonrevenue-producing natural gas pipeline through a gas infrastructure replacement mechanism, including, without limitation, the replacement of master meter systems, early-vintage plastic pipe, early-vintage steel pipe or any other gas infrastructure replacement project authorized by the Commission for the purpose of addressing a safety and reliability concern that justifies replacement on an accelerated basis and that would otherwise serve the public interest.
