The governance of environmental risks and performance is guided by our Enterprise Risk Management Framework and our Safety Management System Framework. These two frameworks provide the tools, techniques and accountabilities for compliance and performance that our business segments use to effectively manage all of their risks and obligations for safeguarding people, property and the environment. Post our 2017 consolidation with Spectra Energy we also began development of an enterprise-wide management framework for environmental protection as one of the six mandatory pillars that provide the foundation for our Safety Management System. In addition, each of our business segments have their own Integrated Management System (IMS) and Environmental Protection Programs (EPP) that are custom designed to respond to the different requirements and complexities of their specific operations. The development and implementation of these frameworks is informed by industry-leading protocols, including, but not limited to, ISO 14001.
