PIPELINE INTEGRITY
The safe, environmentally responsible operation of our pipelines has always been our priority. The integrity of a pipeline system reflects on the reputation of the operator as a reliable transporter of energy who can be depended upon by customers to deliver these products on time and in a cost-effective manner. And, doing everything possible to prevent leaks is what our host communities expect from us as a responsible neighbor.
Enbridge supplements its comprehensive maintenance procedures with integrity management plans for ourLiquids Pipelines and Gas Transportation systems. These plans describe how some parts of our pipelines have a greater potential for affecting public areas—where people live, work or play—or environmentally sensitive areas in the unlikely event of a leak.
Enbridge works with federal and state regulators and local emergency responders to verify that these integrity management plans, pipeline testing and preventive measures are appropriate for the conditions along the route segment.
Major Integrity Projects
The majority of integrity actions taken involve assessment, maintenance and rehabilitation of the pipeline system within the existing right-of-way. Periodically, Enbridge undertakes a larger program that involves replacement and construction projects. These projects are typically subject to local, state and federal regulatory approvals and coordination with landowners.
Liquids Pipelines Integrity Management Plan
Our Liquids Pipelines integrity management program addresses aspects of evaluating and maintaining pipeline integrity to minimize the risks and consequences of having a pipeline failure that could impact populated areas and surrounding environments.
Federal and state pipeline regulations provide strict guidelines for pipeline companies like ours to develop, maintain and continuously improve integrity management programs to protect high consequence areas (HCA). These regulations require pipeline operators to identify HCA located along the pipeline that are heavily populated and are unusually environmentally sensitive that could be affected by an unintended release of the product transported inside the pipeline.
Gas Transportation Integrity Assessment and Risk Management Plan
We manage the integrity of our natural gas systems by identifying, assessing and mitigating the risk of a natural gas release, particularly as it relates to design, construction, operation and structural integrity. To supplement our normal maintenance practices, we have developed an Integrity Assessment and Risk Management Plan for our natural gas systems in higher populated areas. This plan evaluates the probability of a failure on a pipeline system and the consequences of such a failure. Components of this integrated plan include:
- Risk assessment.
- Integrity assessment.
- Risk mitigation.
- Performance measures.
- Management of change.
- Communications.
- Quality control.
The U.S. Pipeline and Hazardous Material Safety Administration's Office of Pipeline Safety provides transmission pipeline operators with specific guidelines on integrity management plans. In some states, regulators have expanded on these federal requirements to govern practices on intrastate pipelines in their jurisdiction.
