  • Introduction This document is intended for anyone involved in planning or carrying out work in the vicinity of Enbridge Gas Distribution’s (EGD) network. It summarizes the requirements to be followed and specifies the technical requirements aimed at protecting EGD’s Facilities, and by extension, ensuring public and worker safety. These Requirements supersede the prior version of EGD's Third Party Requirements in the Vicinity of Natural Gas Facilities, version 2.1 (2015). Version 3.0 (2018) is effective on June 6, 2018. Within this document, "Third Party" refers to an individual or organization that is not employed by or performing work under contract to EGD. These Requirements are applicable to work done by individuals such as homeowners, other utility companies, Excavators, Constructors, and Contractors. Third Parties must follow the regulations and legislation applicable to their work in addition to these Requirements. It is understood that all legal provisions applicable to work carried out around natural gas Facilities take precedence over this document. The terms “gas lines”, “gas pipelines”, and “mains” used throughout this document apply equally to natural gas mains and service lines, as well as any other component of the EGD’s natural gas distribution system found on public or private land.
