Enbridge, millions of people across North America rely on the energy you deliver. What are you doing to make sure your operations are safe and reliable?

Millions of people across North America count on the energy we deliver every day, so our top priority is and always will be the safety and reliability of our operations. It’s our duty and responsibility to prevent incidents, be safe and reduce our environmental impact.

Safe and reliable operations have always been the foundation of our business. Over the years we have built a strong safety record. For example, in the past decade we’ve transported 13 billion barrels of oil with a safe delivery record of 99.9993 per cent. But that’s not good enough.

Our mindset today is that while we know incidents could potentially happen, we believe that all incidents can be prevented. This approach is more than just words; it is backed by action, a relentless focus on safety by every member of our team and the investment of billions of dollars to make our systems even safer. It’s the necessary foundation for how we operate.

With this, our first safety and operational reliability overview, we want you to know how we measure up, so we’re talking about our performance and what we’re doing to further enhance our safety record.

That’s our Number 1 priority as an organization and as individuals.

Planning and building our projects How do you make sure your new projects are safe and reliable, and how do you protect the environment?

how do you build safety and reliability into your projects?Our safety and operational reliability work starts long before we begin to build and operate any energy infrastructure.

We carefully select pipeline routes and line locations and maintain world-class standards for engineering and design, including special design requirements for areas such as road, river and creek crossings. We take the same rigourous approach with our other facilities, such as pump stations, terminals, plants and renewable energy sites.

Our projects require specially designed and engineered materials. We set world-class standards for materials procurement, including selection of pipeline materials (see story on page 7), corrosion-inhibiting coatings, and cathodic protection, applying a small electrical current to pipelines to prevent corrosion.

We use leading construction practices, including a commitment to identify, mitigate and proactively manage potential construction project effects on the environment. We pay close attention to environmentally sensitive areas and at-risk species.

Our projects and operations are subject to rigourous oversight and approval by federal, provincial and state regulators to ensure that we are complying with all applicable laws and regulations.

Ensuring integrity begins with precision manufacturing and testingEach year Enbridge purchases thousands of tonnes of pipe from plants in Saskatchewan, Alberta, Oregon and Florida, with over 93 per cent produced at a mill complex in Regina owned by Evraz North America. Here, recycled metal is converted into liquid steel in electric arc furnaces, cast into large slabs, then rolled and welded to produce

the high-tensile pipe needed for new projects and relied on to carry oil at high pressures and large volumes.

Producing the pipe involves meeting exacting requirements for quality and integrity. A comprehensive inspection system helps Enbridge to achieve this quality – step by step and with precision.

Expert inspectors hired by Enbridge watch every step in the manufacturing process. They examine the formed pipe for possible defects. They monitor ultrasonic and x-ray tests that examine the integrity of each weld. Using calipers and micrometers, they assess each section for exact tolerances on diameter, roundness and straightness.

“Our inspectors touch and measure every inch of the pipe,” says Allan Wilson, Supervisor of Quality Management at Enbridge Pipelines. “We’ll check the heck out of each pipe until we’re absolutely satisfied.”

Safety begins with a thoroughly and professionally engineered design, followed by clear criteria on how the construction work is to be safely executed. Our contractor selection process is designed to ensure the contractor selected has the right capacity, competence and safety skill sets and, equally important, has demonstrated through various safety metrics that it can execute the work to Enbridge’s safety standards. We conduct this selection through a review

of each contractor’s history with Enbridge and through a third-party evaluation of the contractor’s safety system by the ISNET World verification agency. All safety obligations and expectations are specified in the Enbridge contract and laid out in further detail within the Enbridge Contractor Safety Manual (CSM). All contractors are required to fully comply with the CSM.

A Project Safety Plan dictates specific safety expectations for the Enbridge project team that’s accountable for managing the contractor and its work. Our Major Projects team uses a Project Scorecard to itemize safety performance and activities for each reporting period. This data is reviewed with the contractor. In turn, Enbridge’s senior management team reviews all projects

for progress and any constraints on safety, quality, cost and schedule. We also engage monthly with the contractor’s leadership team. In 2013, we plan to implement periodic third-party safety audits. In addition, work is being constantly monitored by safety inspection staff on behalf of both Enbridge and the contractor.

Enbridge is committed to ensuring that all employees and contractors return home safe and healthy at the end of every day. To act on this commitment, our Major Projects unit has taken the lead in driving safety improvement by establishing both a U.S. and a Canadian Pipeline Construction Safety Roundtable.

The Roundtables include mainline pipeline construction contractors and the primary pipeline owners who gather to discuss the challenges and required improvements to raise the safety performance of the industry.

Since mid-2012 we have held six Roundtable gatherings in Canada and the U.S. Going forward, the Roundtables will be held approximately every six months.

The Roundtable participants have shared information on more than 10 incidents that have occurred throughout industry and are developing a standardized incident learning

template. The gatherings have also commis-sioned research on front-line supervision across the industry to identify training needs, and have also undertaken a survey on alcohol and drug programs in use throughout the pipeline construction industry, sharing the findings with all contractors.

By working with our partners across North America, we can raise safety standards and drive cultural safety improvement across the industry.

One of the key safety improvements coming out of the Roundtables has been the establishment of rollover protection guidelines for sidebooms, the specialized heavy machinery that lowers the pipeline into the trench during construction. These new standards mitigate the risk of rollovers and enhance the safety of pipeline construction personnel.

What are you doing to protect the environment?Our commitment to safety and operational reliability requires that we protect the environment. As a result, we strive to reduce our environmental impact so that we can safely and reliably deliver the energy North America needs with the smallest environmental footprint.some examples of our focus in this area:› Our emergency response protocols are

based on keeping people and communities safe and protecting the environment.

› We rigourously adhere to environmental permitting and regulations.

› We employ new construction methods, such as horizontal directional drilling, to reduce our impact in sensitive areas during pipeline construction.

› We conserve valuable resources with our demand-side management program – through which we have helped our Gas Distribution customers to reduce their energy consumption, saving 7 billion cubic metres of natural gas since 1995.Enbridge is also a leader in the generation

of renewable energy, and we are Canada’s Number 1 solar energy producer and Number 2 wind energy producer.

76 Enbridge Inc. 2013 Operational Reliability Review

Operations and monitoring What steps do you take to watch over your systems and to ensure that they are operated safely and reliably?

how do you keep your pipelines safe once they’re in service?We focus on the conditions that have been known to cause pipeline failures in the past and then work to minimize the risk. We invest heavily every year in the most advanced leak detection, damage prevention and pipeline integrity management technologies.

We’re recognized by our peers as being at the forefront in the use of the best technologies. We work collaboratively with pipeline inspection vendors – challenging the limits of their technology and supporting research,

development and testing of new tools that further advance our prevention capabilities.

We also work to operate our pipelines in a way that protects the quality we build in at the start, and maximizes the integrity of our systems. For example, we strive to manage and minimize pressure cycling on our pipelines – the fluctuations that occur in the course of operations as you start and stop pumps and move crude oil products with different densities and viscosities – so that we reduce the stresses that can lead to wear on our pipeline systems.

how do you make sure your pipeline operators are performing at their best?In December 2011, we opened our new Control Centre in Edmonton, Alberta. The new centre creates a work environment specifically designed to enhance the safety and reliability of our pipeline operations by creating the optimal conditions to support our operators as they conduct our critical around-the-clock operations.

The new facility allows for greater interaction and enhanced support for our 24/7 operations and is designed to address fatigue management and maximize human performance through such features as sit/stand consoles, improved lighting and noise reduction.

In addition to the new facility and technology, over the last two years we’ve made numerous enhancements to our Control Centre Operations (CCO):

› We developed and implemented a Control Room Management plan.

› We revised and enhanced all procedures pertaining to decision-making, handling pipeline startups and shutdowns, leak detection system alarms, communication protocols, and suspected column separations.

› We enhanced the organizational structures to better support our operators and to manage span of control and workloads.

› We augmented CCO staff, adding training, technical support, engineering and operator positions.

We monitor our pipelines for possible leaks using four primary methods, each with a different focus and featuring differing technology, resources and timing. Used together, these methods provide multiple layers of protection and comprehensive leak detection capabilities.Monitoring Enbridge’s Pipeline Controller monitors pipeline conditions (such as pipeline pressure) through the Supervisory Control and Data Acquisition (SCADA) system, which is designed toidentify and raise an alarm in response to unexpected operational changes such as pressure drops, which may indicate a leak.Visual surveillance and odour reports These are reports of oil or mercaptan odours provided by third parties and from Enbridge’s aerial and ground line patrols. Third-party reports are handled through a toll-free 1-800 emergency telephone line, which the public near our systems and local emergency officials are made aware of through Enbridge’s public awareness programs. Our Liquids Pipelines business unit

typically conducts aerial line patrols every two weeks on its entire system, while Enbridge Gas Distribution conducts weekly patrols on most of its lines. Gas Transportation conducts a series of leak surveys, including mobile, building and walking surveys.scheduled line-balance calculationsWe calculate oil inventory at fixed intervals, typically every two hours and every 24 hours, to identify unex-pected losses of pipeline inventory that may indicate a possible leak. computational pipeline monitoring (cpM) CPM is a computer-based system that utilizes measurements and pipeline data to detect anomalies that could indicate possible leaks. The CPM system provides a sophisticated computer model of Enbridge’s pipelines that continuously monitors changes in the calculated volume of oil between two fixed points on the system. If the calculated volume of oil is less than expected, then an alarm is triggered in Enbridge’s Control Centre. The cause of the alarm is investigated immediately.

To detect pinhole leaks that are very difficult for any pipeline operator to detect, we’re using sophisticated acoustic technology carried by in-line inspection tools that move through the pipeline. These tools are so sensitive that they can detect, for example, a leak of 30 litres per hour on a line that’s delivering 3 million litres an hour.

Monitoring the health of our pipelinesFor all parts of our pipeline operations where in-line inspection (ILI) tools can be employed, we regularly and continually inspect our gas distribution, gas transportation and liquids systems using sophisticated ILI tools.

how do you detect pipeline leaks?

inspectionsWe inspect all of our mainline system from the inside out, using the most sophisticated inline inspection (ILI) tools available to us. While we’ve always been one of the biggest users of technology and technical resources for pipeline integrity, we’ve doubled our efforts and established Enbridge as an industry leader in the use of ILI tools.Managing crackingEnbridge is committed to being at the forefront of technological developments and research relating to cracking and its diagnosis. Cracking is a phenomenon that can occur in metals, including pipeline steel. We have rigourous programs in place for monitoring and managing cracking, our key activity being the use of high-resolution ultrasonic in-line inspection technologies.combating corrosionWe look for and then prevent any corrosion of the steel in our pipelines and facilities. We achieve this by using anti-corrosion coatings; low electrical currents that protect the steel against corrosion; chemicals to pre-vent internal corrosion; regular monitoring and inspections; and cleaning pipes from the inside with in-line devices known as “pigs.”integrity within facilitiesWe aim to operate and maintain all of our facilities, including pump stations and terminals, in a safe, responsible manner. We accomplish this through our design standards; equipment and construction specifications; commissioning, operating and maintenance procedures; and targeted

tankage, equipment and piping inspections. A team of subject-matter experts in Engineering, Operations and Integrity guides a leak reduction program for the network of facilities throughout our liquids pipelines system, including pump stations and terminals. preventing mechanical and third-party damageWe strive to prevent any dents, scrapes, and other damage to our pipes and facilities during construction and operation or by third parties. Given that third-party damage is one of the leading causes of pipeline leaks, public awareness is a vital element of pipeline safety. Enbridge has a comprehensive public awareness program in place to engage landowners, community members and first responders to ensure that they are aware of our pipelines and related facilities. replacement programsWhen needed, we replace our pipes and facilities. For example, Enbridge Gas Distribution has replaced all of its cast iron pipes and fittings over the last 10 years. This means that our gas distribution system is safer, since the cast iron that was installed years ago became brittle and leaked over time. It also means we’re protecting the environment by reducing gas losses into the air.

integrity What do you do to maintain the health and operational fitness of your systems?

how do you know if a pipeline needs to be repaired?Enbridge’s monitoring and inspection program alerts us to pipeline features that may require a visual inspection to determine if a repair or other action is required. Each year we run high-resolution in-line inspection tools inside our pipelines to examine thousands of miles of our systems.

An integrity dig is the method we use to inspect our pipeline where our in-line inspection tools have identified a feature that requires a closer look. Each year, we conduct thousands of excavations to examine small sections of our pipelines in this way. Each dig

involves excavating a section of buried pipe so we can carefully clean and examine it. We use sensitive x-ray and ultrasonic technology to identify any internal or external physical changes in our pipeline. If we find a defect, we repair it, recoat and re-bury the pipe. In some cases, we cut out old sections of pipe so we can weld in new pipe. Features that have been known to require a repair include third-party excavation damage, weld concerns, corrosion, and cracking or denting.

Our regular, millimetre-by- millimetre inspections of our pipelines using sophisticated high-resolution in-line inspection tools allow us to identify features – such as indications of dents, cracks or corrosion – that require a closer look and maintenance. When we detect such a feature we undertake an integrity dig – safely exposing the pipeline so that we can examine it visually and using other techniques – and make any necessary repairs.before the integrity digPrior to beginning any integrity dig we analyze the unique details for each location and develop a plan for how we will complete the work. This involves establishing a safe work plan, consulting with landowners, working with regulators to get all of the necessary regulatory approvals and identifying the best access to the site.

stEp 1

preparation of the dig siteEnbridge temporarily stakes out the access route and the site of the excavation on the right-of-way. Topsoil is stripped from the excavation site and stored separately from the subsoil.

stEp 2

Excavation to expose the pipeUsing a backhoe or other machinery, the subsoil surrounding the pipeline is carefully removed and stored.

stEp 3

cleaning the exposed pipeA crew removes the protective coating and sandblasts the pipe to ensure it is ready for a detailed inspection.

stEp 4

inspection of the pipeEngineers analyze the pipe anomaly visually and using laser-scan and ultrasound tech-nology that measures the exact dimensions of corrosion or other features. This data is compared against the inspection-tool data to determine whether any changes in the pipe indicate a need for maintenance.

stEp 5

Maintenance or repair, and inspectionIf there are early signs of corrosion, the pipe is cleaned and the coating repaired as a preventive measure. Corrosion can often be detected years before it becomes an issue. In other cases, the pipe section will be replaced completely, or a sleeve installed to restore strength to one area of the pipe. All welds are then visually inspected and tested using x-ray and ultrasonic technology to ensure the system is safe. The section is also inspected to ensure the repairs satisfy industry and government standards.

stEp 6

recoat the pipeThe pipe is sandblasted and recoated with an improved protective layer that will last the life of the pipeline.

stEp 7

backfill excavation and cleanupThe excavation is backfilled immediately, and the landscape restored. Depending on the time of year, restoration may be delayed until the next spring season, but in the meantime the site will be monitored.

stEp 8

Environmental remediationThe site is monitored for approximately one year to ensure that any disturbance to the landowners’ properties is fully restored, and landowners are compensated for impacts to their land.

lOwEr EMissiONsReplacing cast iron mains has reduced GHG emissions by 37,000 tonnes per year, the equivalent of taking more than 7,700 passen-ger vehicles off the road.

Reducing GHG and fugitive emissions in our Gas Distribution business Between 2006 and 2012, Enbridge Gas Distribution replaced approximately 545 kilometres of cast iron natural gas distribution mains in Toronto – the last cast iron mains in our system. Replacing these mains has resulted in an estimated reduction

of greenhouse gas (GHG) emissions equivalent to 37,000 tonnes of CO2 annually, the equivalent of taking more than 7,700 passenger vehicles off the road. The replacement also reduced fugi-tive losses – small, dispersed leaks of natural gas from the system – by about 20 per cent in our Ontario operations.

Enbridge tackles a challenging mid-lake pipeline integrity digWhen in-line inspection found an anomaly in a section of Line 51 in northeast Oklahoma, Enbridge crews were faced with the unique challenge of how to investigate. The 40-foot section of pipe that needed to be inspected runs across the bottom of Oologah Lake, a major source of drinking water for the

city of Tulsa and much of the surrounding area. To carry out the inspection, the line was first shut down and purged of crude oil. A team of experienced divers went down through 20 feet of water to dig through silt and access the pipe. After confirming the presence of a hairline crack about 4.5 inches (10 cm) long and with a depth of approximately 0.2 inches – 58 per cent of the pipeline’s total wall thickness of 0.345 inches at that location – they bolted a metal sleeve to the pipe exterior to repair the line. Because of muddy conditions, divers used GPS co-ordinates to

pinpoint the feature, while video cameras and live audio feeds updated workers on a surface barge throughout the process. A silt curtain was installed surrounding the site to prevent debris from spreading to other parts of the lake, and water quality near the work area was tested daily to ensure no contaminants were present.

“Local residents told our project manager that the community was very impressed with how Enbridge as a whole conducted the dig,” says Carlos Pardo, Enbridge Pipelines’ Director, U.S. Engineering and Projects.

Pardo credits smooth execution of the dig to proper planning. “Projects of this kind require an experienced team, comprehensive risk analysis and coming up with a detailed execution plan that can deal with the unique complexities of the site.”

To minimize the impact of the work on the lake bed, crews installed silt curtains to keep debris from spreading and water quality was tested daily.

To make the repair, divers first removed a 3-to 4-inch-thick coating of concrete from the pipeline, and then bolted on a specialized clamp to reinforce the 0.345-inch-thick steel walls of the pipeline.

A team of experienced divers equipped with video cameras and live audio feeds worked in murky underwater conditions to repair the pipe.

Safety, emergency response and preparedness How do you keep the public, your employees and the environment safe and what do you do in the event of an incident?

how do you prevent, prepare for and respond to incidents?Our goal is 100 per cent safe operations of our systems and we are committed to preventing incidents. At the same time we must be prepared to respond quickly and effectively to protect people and the environment if and when an incident occurs.

Public awareness of our operations is of primary importance in preventing incidents from causes such as third-party damage to our facilities from unauthorized excavation, and it is also critical in helping landowners,

community members and first responders recognize and report incidents and know how to stay safe if an incident occurs.

We invest millions of dollars in equipment and emergency response supplies staged at strategic locations and we train our employees and contractors on an ongoing basis. We also provide training to first responders to help prepare them should an incident occur.

Part of our commitment to training involves engaging in hundreds of drills, emergency exercises and equipment deployments with federal, state, provincial and municipal agencies each year, during which we test and refine our response plans so that we have the shared knowledge and experience to respond to any incident.

providing enhanced pipeline emergency training for first respondersEnbridge is enhancing the training it provides emergency responders along its U.S.–Canada pipeline system by introducing a new program that includes an interactive online course and in-person sessions.“We see this program as critical to reaching a large number of emergency response agencies with consistent, comprehensive information about the products we transport and the most effective tactics for responding to a pipeline emergency,” says Kesley Tweed,

Supervisor of Public Awareness for Enbridge Gas Transportation in the United States.

In December 2012, the company launched an online portal to provide free customized training to first responder organizations. Based on Pipeline Emergencies, a program developed by the National Association of State Fire Marshals, the website features 3-D interactive graphics to help first responders better visualize response to pipeline incidents. More recently Enbridge has begun rolling out an in-person outreach component, targeting fire departments and 911 dispatch centres near its pipelines and facilities.

The training has been made available to approximately 8,800 first response organizations across

Canada and the United States and, so far, more than 1,200 individuals have registered for the training. A group of 50 employees from across U.S. operations were trained in March and May of 2013 to serve as emergency response ambassadors.

“Our ambassadors will be connecting with key organizations along our rights-of-way,” Tweed says of the employees, who will help to lead safety meetings, facility tours and training sessions. The face-to-face and in-person outreach initiative, which is also being deployed in Canada in 2013, supplements Enbridge’s ongoing first responder activities, which include full-scale emergency response exercises.

Online training and in-person outreach prepare first responders for natural gas and liquids pipeline emergencies.

While our goal is first and foremost to prevent all incidents, we also have comprehensive incident response and environmental mitigation plans in place to respond rapidly and completely if a spill occurs. No matter what the size or location of the release, we take every incident very seriously. We take responsibility and treat it as a top priority.

Each of our business units has emergency preparedness and response plans in place to minimize the impact of an incident and comply with regulatory requirements. We also work closely with local first responders and communities to ensure that they are aware of our systems and what they should – and should not do – in the event of an emergency. When Enbridge experiences a release, we carry out emergency response procedures to shut down and isolate the impacted pipe, notify the appropriate government and regulatory agencies, contain the substance as appropriate, and manage potential environmental and safety impacts.

For example, when we experienced a release on Line 14 near Grand Marsh, Wisconsin, on July 27, 2012, our monitoring systems immediately alerted our pipeline operators, who shut down the line within minutes. At the same time, a local landowner called in to report the release, using the emergency number on an Enbridge fridge magnet distributed as part of our public awareness program. Crews arrived on scene within 45 minutes of the initial alarm to contain the release and begin the cleanup.

At the height of the response, August 1, there were nearly 400 personnel on site. The pipeline was repaired and returned to service on August 7 and the site was completely cleaned up within six weeks of the incident.

Our highest priorities are the safety and protection of people and the environment, rapid response and thorough containment and cleanup to minimize the impacts. We work closely with emergency first responders, landowners, regulatory agencies and other concerned parties to develop any necessary remediation and monitoring plans. Our goal is to address the requirements of all regulators and stakeholders and to restore the area as closely as possible to its pre-spill condition or to a state that’s acceptable to the local community.

How do you learn from your mistakes?We fully investigate every incident to determine the root causes and contributing factors and we incorporate our findings, as well as those of regulators and other agencies, into actions focused on improving our management systems.

We also review the effectiveness of our incident response to identify areas where we could improve.

To help enhance the overall safety of our business, we share the lessons we learn with stakeholders within Enbridge, across industry and with regulators and first responders.

Enbridge employees in Canada and the United States participate in regular emergency response drills and simulations to test and improve our preparedness procedures. In 2012 we staged more than 380 exercises, drills and equipment deployments across the company.

Employees are trained through workshops, tabletop exercises where various scenarios are discussed, and procedural drills. We also perform full-scale exercises – 33 in 2012 – involving local emergency agencies using equipment to practice recovery and cleanup in various terrains and/or on water. We also deliver specialized training for the Enbridge Enterprise Emergency Response Team, a cross-business unit response team, to respond to large-scale events anywhere

in North America that would require more resources than a single region or business unit could provide. The response team has been conducting major training exercises involving all of Enbridge’s business units, emergency response contractors and consultants, and federal, state/provincial and local emergency response agencies.

what are you spending on preparedness?From 2012 to 2013, $50 million was spent to improve our equipment, training and overall response capabilities. This includes new equipment – ranging from containment booms to boats – that is being deployed across our systems.

Safety, emergency response and preparedness

What principles do you follow when it comes to health and safety?In April 2013, we introduced and widely communicated six Health & Safety Principles that outline how we think about health and safety at Enbridge and guide our actions, policies, procedures and culture. The six Health & Safety Principles are:1 All injuries, incidents and occupational

illnesses can be prevented.2 All operating exposures can be controlled.3 Management is accountable for safety

performance.4 All employees/contractors are responsible

for safety.5 Assessment and improvement are a must.6 We promote off-the-job health and safety

for our employees 24/7.

technology and Operations centre delivers state-of-the-art training to workersEnbridge Gas Distribution’s (EGD) new Technology and Operations Centre in Markham, Ontario, opened in October 2012 and is a leading gas distribution training facility in North America – both technically and environmentally.“We have a training facility that has all the main elements of a gas distribution system so workers can be trained and leave with

the confidence that they can do their job safely,” says Anne Creery, EGD’s Director of Quality and Training. The centre brings the company’s 89 technical training and environment, health and safety programs under one roof. Between July 2012 and June 2013 the centre saw more than 15,000 enrolments from Enbridge employees and contractors.

A hallmark of the centre is a streetscape, where workers are trained to deal with real-life situations – such as locating pipe, conducting leak surveys or extinguishing fires – in a safe, controlled environment. The 1.5-acre site consists of roads and buildings common in an urban community with a gas distribution system. Compressed air is used to

simulate natural gas. On-site instruc-tors can change learning tasks with a touch of a computer tablet, further testing students’ ability to respond.

“This realistic, dynamic approach to training allows us to further develop our workers’ expertise and continually improve our ability to deliver gas safely,” says Creery.

We’re building a strong safety culture across all of our businesses with a target of zero incidents, injuries and occupational illnesses.

In 2013, we launched and communicated the six Health & Safety Principles that outline how we think about employee and contractor health and safety at Enbridge. These Principles complement the Enbridge Values by guiding our actions, policies, procedures and culture.

In addition to specific job-related policies and procedures to keep our employees and contractors safe, we also teach every member of our team about the Enbridge Lifesaving Rules. These six fundamental safety rules for our employees and contractors are based on past incidents at Enbridge and focus on areas of high risk and high consequence. The Lifesaving Rules are mandatory and

every member of the Enbridge team is required to know and follow them at all times.

Further reinforcing the importance of safety, we have established specific and tangible safety performance targets for individual employees, business units and for our company as a whole that recognize and reward strong safety performance.

Enbridge is committed to ensuring that everyone returns home safely at the end of each and every day, and that our assets are operated in a safe manner. This commitment to safety is based on caring for employees, our contractors, the communities in which we operate and the environment. The Enbridge Values – Integrity, Safety and Respect – establish how we conduct our affairs individually and collectively at a moral and ethical level.

how are you building a strong safety culture embraced by all members of your team?

We regularly communicate with a diverse group of stakeholders right across North America about pipeline safety. This includes thousands of one-on-one and group meetings every year as well as written communication with hundreds of thousands of stakeholders. For example, nearly 1 million brochures are mailed annually to targeted U.S. stakeholders – reminding them of pipeline safety, providing information on how to recognize and respond to a pipeline emergency and ensuring they have the necessary contact information.

how do you ensure that health and safety are built into all aspects of your business?Enbridge takes employee safety seriously. Before employees are authorized to perform any job that may have health or safety risks associated with it, they must complete mandatory training. Enbridge’s business units are directly accountable for safety. Within each of our business units and at each of our sites, we’ve established health and safety committees that meet regularly to discuss and proactively implement changes in response to legislation, new policies and practices and new understanding gained from analyzing incidents.

We believe there must be a strong drive to continuously improve our safety culture. We’re focused on moving from a management-driven, control-based approach to an interdependent culture, where our employees and contractors are not only concerned about their own safety, but also the safety of all of those around them, and where safety becomes an integral business value and source of organizational pride.

research and innovation How are you using new technologies and investing in research to improve the safety, reliability and environmental performance of your systems?

What technologies do you use to inspect your pipelines?The in-line inspection devices we use to inspect our pipelines are so sophisticated they can sense and measure the size, frequency and location of even minute changes on both the inside and the outside of pipe walls, providing a level of detail similar to that provided by MRI, ultrasound and x-ray screening in the medical industry.

Since 2009, our Liquids Pipelines business unit has invested approximately $3.2 billion to improve our pipelines and facilities and has conducted more than 480 in-line inspections, with another 187 planned for 2013. The rising number of in-line inspections reflects our commitment to ensuring the safety and reliability of our pipeline systems.

investing in energy storage technologyWith renewable energy projects capable of generating more than 1,700 MW of emissions-free energy – that’s enough to power nearly 570,000 homes – Enbridge is rising to the challenge of managing the natural ebb and flow of renewable energy by find-ing new ways to store electricity for use when it is needed.As Canada’s top producer of solar power and Number 2 producer of wind power, with large renewable energy projects in the U.S. as well, Enbridge is investing in technologies that support large-scale energy storage.

In 2012, Enbridge invested

$5 million in Hydrogenics Corporation, whose water electrolysis technology can convert surplus renewable energy into ultra-clean-burning hydrogen gas. By converting electricity to gas, the hydrogen can be stored in vast natural gas pipeline networks such as Enbridge Gas Distribution’s system. The stored electricity can be returned to the grid, when required, using gas-powered generators. Additionally, it has the flexibility to expand the market for renewables with green energy that can be supplied for uses such as home heating and oil refining.

In early 2013, Enbridge also invested $5 million in Temporal Power, developer of an innovative flywheel technology. A cylinder suspended in a vacuum chamber, the flywheel acts as a mechanical

battery: when the wind is blowing or the sun is shining, it charges by using a motor to spin the cylinder; later when it’s time to extract electricity, the flywheel uses kinetic energy to spin a generator. Each flywheel can produce 500 kilowatts of power. Flywheels can be grouped in modules to provide scalable generation facilities.

“Electricity storage devices such as power-to-gas and flywheel technologies can be enablers of renewables. By investing in these technologies, we’re helping to advance society’s acceptance of intermittent sources like wind and solar,” says Chuck Szmurlo, Enbridge’s Vice President of Alternative and Emerging Technology.

Surplus power can be used to capture hydrogen from water. The hydrogen can be safely stored underground for later use or injected into natural gas pipelines.

researching and testing new ways to detect pipeline leaksIn Edmonton, a unique pipeline research project is taking shape, with funding support from Enbridge Pipelines. The facility, unveiled and put into service in the fall of 2013, provides Enbridge with a world-class apparatus to assess the ability of some of the newest cable-based technologies to detect oil leaks.“We’re partnering with a local research firm to build a one-of-a-kind pipeline test facility,” says

Ray Philipenko, Enbridge Pipelines’ Senior Manager of Leak Detection.

Working in partnership with the Alberta government, Enbridge Pipelines is investing $3 million toward the development of the laboratory equipment at C-FER Technologies, an applied research organization. A centrepiece of the facility is a 40-foot section of 24-inch diameter pipe similar to that used to carry product along Line 2 on Enbridge’s mainline. Starting in October, 2013, C-FER scientists and engineers began using the apparatus to study the reliability and sensitivity of different sensor cables in response to varying leak rates of diluted bitumen, changing fluid temperatures and adjusting the proximity of the cables to the pipe.

One promising technology uses fibre-optic cable, installed along the pipe exterior, to detect changes in ground temperature caused by the release of product. Another pumps air through a tube to measure minute traces of hydrocarbon vapour in the soil, while an electrical-based technology indicates changes in transmitted energy pulses as a result of contact with hydrocarbon liquids.

“We’re looking to get more information on how these different technologies perform in real-world operating conditions and how we can potentially apply them to our pipeline operation.”

Fibre-optic cables can be used to detect tempera-ture changes associated with a leak.

Using acoustic-sensing technology, fibre-optic cables can be employed to “hear” leaks, or even footsteps or digging along the pipeline.

New leak detection technology will be tested at Enbridge’s one-of-a-kind leak detection test facility in Edmonton, AB.

Hydrocarbon-sensing cables would physically change in the presence of hydrocarbons, compress-ing signal wires and triggering an alarm.

Vapour-sensing tubes laid along the pipeline could detect hydrocarbons released in the event of a leak.

Measuring progressis Enbridge getting safer?

how does Enbridge’s safety performance measure up?In this review of our safety and operational reliablity performance we’ve talked about just a few of the different programs we have in place and the many investments we’ve made in our quest for zero incidents and 100 per cent safe operations.

In addition, Enbridge continually gathers data on our performance so that we can measure and report on our progress, the actions we are taking and our results.

But with all that work, how does Enbridge’s safety performance measure up, and is it improving?

As the results in this section demonstrate, our safety and operational reliability performance is strong and is moving in the right direction. But it could still be better, and that is where we’re focusing our efforts in the years ahead.

We are making progress on our path to zero incidents and we will continue to share our results with you – good and bad – so that you can see for yourself how we measure up to the important and complex role we play in delivering the energy you count on.
