High Consequence Area Definition Supports Prevention of High Consequence Pipeline Events
The session will discuss how defining High Consequence Areas can prevent High Consequence Events. The discussion will cover risk, regulatory requirements, operational practices and standards as they pertain to High Consequence Areas. Discussion will also include how defining what is high consequence is allows for consistent approach to assigning critical activities in an effort to reduce or eliminate High Consequence Events.
Prevention of High Consequence Events is critical and prioritizing both financial and human resources available to operators is important. With the public outcry over pipeline events the reaction by both the public and the regulators has in many cases been more of a shotgun approach and is trying to solve too many problems at once without priority in approach.
All pipeline integrity programs must work in a risk based manner to effectively manage risk and prevent pipeline leaks. Risk based programs are often developed in house by each operator and the sophistication of their risk tools is highly variable from a qualitative spreadsheet to high level modelling and analysis.
Pipeline operators come in many forms, from large transmission pipeline operators that deliver refined product through large diameter pipelines to small upstream oil and gas operators that deliver unrefined products through thousands of small diameter pipelines from the wellhead to their facilities.
Upstream operators suffer greater than 1 leak per year per 1000 km of pipelines and many of these leaks are small and easy to cleanup. But some have significant impact on people and the environment.
Currently a definition of what a High Consequence event is doesn’t exist and is required to consistently define high consequence areas. Currently it is left to every operator to create their own definition and incorporate this into their risk tools.
This is a problem as it leaves the risk tolerance up to the operator and this may not reflect the risk tolerance of Canadians. It leaves discretion by operators to do what they can afford and gamble with risk.
By defining High Consequence Areas (HCA’s) it sets a mechanism for targeting a higher level of requirements for HCA’s and helps to maintain the risk tolerance of all Canadians not just the pipeline operator. At the end of the day high consequence events affect all of us, our sensitive water bodies, our communities, and the reputation of our industry.
