A robust program of integrity digs is one of the many reasons that the Canadian energy transmission pipeline industry is a standout among its global peers.
Pipeline
Performance
How your pipelines performed in 2019.
In 2019, CEPA members safely transported the natural gas and oil that you, Canada and the world count on.
Natural Gas
To give you an idea, a standard balloon will hold about 5 cubic feet of helium.
Crude Oil
About 160 litres. Or approximately the size of a small bathtub.
Significant incidents
There was one significant incident – a natural gas leak of 12.7 million cubic feet – and zero significant liquids incidents in 2019. While significant incidents decreased from six in 2018, no incident is acceptable as CEPA members are committed to a goal of zero incidents.
A significant incident is defined as an incident with one or more of the following: serious injury or fatality, liquid release of greater than 8 cubic metres (50 barrels), unintentional ignition or fire, or rupture or break of a pipeline.
Total rights-of-way incidents
There were nine total incidents in 2019 of which only one was significant. While CEPA members are prepared for any incident, no incident is acceptable. All CEPA members are committed to achieving zero incidents.
The information in this report covers incidents on CEPA member rights-of-way in Canada between 2015 and 2019. Rights-of-way are strips of land of varying widths that may contain one or more pipelines. CEPA’s focus is on rights-of-way as they represent close to 100 per cent of the network and present the greatest potential exposure to the public.
Natural Gas Incidents
Rights-of-way Incidents
In 2019, there were eight unplanned natural gas releases, of which one was significant. The incident was classified as significant because it was caused by a rupture (a fissure in the pipeline).
Liquids Incidents
Rights-of-way Incidents
In 2019 there was one liquids incident, which was not significant. All 9.4 barrels spilled in the incident were fully recovered.
NATURAL GAS INCIDENTS – TOTAL PRODUCT RELEASED
RIGHTS-OF-WAY INCIDENTS
In 2019, total unplanned product released from CEPA members’ natural gas pipelines was approximately 22.4 million cubic feet.
Released natural gas quickly dissipates into the air.
LIQUIDS INCIDENTS – TOTAL PRODUCT RELEASED VS. PRODUCT RECOVERED
RIGHTS-OF-WAY INCIDENTS
In 2019 there was one liquids incident, which was not significant. All 9.4 barrels spilled in the incident were fully recovered.
When a spill happens, operators work diligently to recover as much of the oil as possible. The amount recovered is carefully tracked as “recovered barrels of oil.”

Prevention Performance
Thousands of professionals — including engineers, scientists and environmental experts such as biologists, agrologists and hydrologists — monitor pipelines to protect the environment. From control rooms and satellites that can monitor every metre of the pipe to in-line inspection tools that patrol the inside of the pipeline, experts are always watching. Below is a report on the year’s prevention performance and ongoing CEPA initiatives in the area of environmental protection.
Integrity Digs
In 2019, CEPA member companies conducted 2,020 integrity digs to examine pipelines for defects and make repairs – that’s a total of 31,445 integrity digs since 2008. The number of integrity digs in any given year is not a set number. Each company decides when and where to perform an integrity dig, based on the results of in-line inspections and according to members’ operations and management programs.
Concerns identified during an in-line inspection or through the supervisory control and data acquisition (SCADA) system in the pipeline control room may be examined by way of an integrity dig. During an integrity dig, a section of land around the pipeline is carefully excavated to give operators an up-close view of the pipeline to determine if a repair or replacement is required.

INVESTED IN MAINTENANCE AND MONITORING
In 2019, CEPA members invested $1.5 billion in maintenance and monitoring of their Canadian pipeline systems.

In-line Inspections
In 2019, CEPA members conducted in-line inspection runs on 38,937 kilometres of pipelines in Canada using highly sophisticated tools like smart pigs that examine pipelines from the inside to identify issues such as metal loss, dents and cracks that may require further investigation.
An in-line inspection involves sending sensors into the pipe to inspect it from the inside. Tools called smart pigs travel through sections of the pipeline. The smart pigs use highly sensitive instruments, similar to ultrasound or MRI, to detect any anomalies in the pipeline, like cracks, dents or corrosion.
Pig stands for pipeline inspection gauge. These are highly sophisticated inspection devices using ultrasound or magnetic resonance technology to detect minute scratches or pin-sized holes in the pipe. Like small submarines, smart pigs travel inside a pipeline to measure pipe thickness and metal loss. Smart pigs travel through the pipeline scanning about three metres per second, locating anything out of the ordinary, like cracks or signs of corrosion, which may then be examined closely in an integrity dig.

INVESTED IN INNOVATIVE TECHNOLOGY
In 2019, CEPA members invested $10.6 million in innovative technology focused on reducing pipeline corrosion and improving pipeline inspection, leak detection and damage prevention. From 2015 to 2019, CEPA members’ investment in these kinds of technologies totalled more than $94.9 million.
This number does not include indirect expenditures on innovative technologies through member company operational budgets.

Safety Performance
CEPA members deliver the natural gas and oil Canada and the world need in the safest, most responsible way. They do this by making safety the highest priority through an ingrained safety culture and exhaustive emergency planning. Below is a report on the year’s performance and ongoing CEPA initiatives in the area of emergency, health and safety.

Emergency response exercises
In 2019, CEPA members held 393 emergency response exercises, ranging in complexity from emergency drills to full-scale exercises with participation from multiple agencies and jurisdictions, and mobilization of personnel and equipment as if a real emergency had occurred.

FACILITY INCIDENTS
In 2019, CEPA members reported 21 incidents within facilities. Incidents that occur within a pipeline facility pose less potential threat to the public or environment because of their size and the fact that facilities have both restricted public access and leak containment systems to keep the releases within the facility.

Member Story
All CEPA members work diligently to prevent any kind of incident throughout the pipeline network.
Injury and motor vehicle incidents
Rate of injury increased from 0.49 per 100 full-time employees in 2018 to 0.88 in 2019. This reflects 16 additional injuries in 2019. CEPA members are committed to zero incidents, including health and safety. Every incident is thoroughly investigated and continuous improvements are made to prevent further incidents.
The number of driving incidents per million kilometres driven fell from 1.62 in 2015 to 0.71 in 2019. Incidents decreased from 1.07 in 2018 to 0.71 in 2019, which represents a 33 per cent decrease from 2018. CEPA members continue to strengthen efforts in areas such as regular driver training and work planning that help ensure workers are not fatigued and have sufficient time to travel the required distances.
The injury rate per 100 full-time equivalent workers is computed by (a) dividing the number of occupational injuries reported by the total number of hours worked by all employees during the calendar year, and (b) multiplying the result by 200,000, which represents the hours worked in a year by 100 full-time equivalent workers (working 40 hours per week, 50 weeks a year).
The motor vehicle incident rate is the number of motor vehicle incidents per million kilometres driven for business use and is calculated by (a) multiplying the total number of incidents by 1,000,000 and (b) dividing by the total business kilometres driven.
FATALITIES
CEPA members are focused on ensuring the people directly employed by our industry and the many thousands of contractors who work on their behalf return home safely at the end of each day. Just as CEPA members have committed to a goal of zero pipeline incidents, they also have a goal of zero incidents affecting the health and safety of their employees.
