Access Pipeline Fact Sheet #3 – PiPeline SAFety And integrityAccess Pipeline is committed to building and operating our oil transportation systems safely. From design and construction to operation and maintenance, safety and integrity are our core values.

the PiPeline SyStem iS monitored 24 hourS A dAy, Seven dAyS A week. Access Pipeline’s head office is located in Calgary, Alberta, with the pipeline control centre and field operations based at our Sturgeon Terminal near Redwater, Alberta.

Access Pipeline currently operates two pipeline systems:

1. A 16-inch, 345-kilometre line that delivers diluent to the SAGD operations.

2. A 24-inch, 295-kilometre line that connects to a 30-inch, 50-kilometre line that transports diluted bitumen (dilbit) from Christina Lake to Edmonton, where the product connects with existing pipeline systems to be sent further downstream to markets.

The pipeline system is remotely monitored 24 hours a day, seven days a week, by our control centre staff at our Sturgeon Terminal, using state of the art control and communications equipment. This supervisory control system provides the necessary safe guards to operate the pipeline in accordance with the Energy Resources Conservation Board (ERCB) and Canadian Standards Association (CSA) regulations.

Each area of our operations is fully staffed with qualified employees who ensure the safe and efficient operation of our facilities.

deSign Access Pipeline uses only steel pipe manufactured to meet stringent standards and top quality welding techniques throughout pipeline system. Block valves are installed at strategic intervals to shut down and isolate the line if required. We take addi-tional safety precautions such as increasing depth of burial and increasing pipe thickness where pipelines cross roads, railway tracks, waterways and in areas of higher population.

ConStruCtion During construction, all welds are checked by an x-ray or ultrasonic process to ensure the welds are sound. To protect against corrosion, the external surface of the entire pipeline is coated prior to installation and the welds are coated during construction. Throughout all stages of construction our process is monitored by trained and qualified inspectors.

oPerAtionTo protect the pipe from external corrosion during operations, a very low-voltage electrical current – called cathodic protection – is applied to the external surface of the pipe. The cathodic protection system is monitored on a monthly basis to ensure proper operation. All of our pipelines are regularly pigged to remove sediment and water and to prevent and control internal corrosion.

The entire pipeline system is monitored 24 hours a day by highly trained Access Pipeline employees from a state-of-the-art com-puterized control center. From here, we are able to detect minute changes in operating conditions along our pipelines and ensure that all facilities are operating properly. The pipeline can be immediately shut down and isolated from the control center if required.

mAintenAnCeRegular maintenance is performed on all portions of the pipeline system. All pump and meter stations also undergo routine maintenance in accordance with industry and government standards.

Access Pipeline has an extensive Pipeline Maintenance Program (PMP) to monitor, inspect and repair our pipeline facilities. Regular maintenance activities include:

• Aerial and Ground Patrols – Operators regularly inspect the pipeline route from the ground and low-flying helicopters and airplanes. They look for hazards to the pipeline from outside sources (e.g. unauthorized activity, soil disturbances) that could affect the integrity of our pipeline system.

• Cover Surveys – Access Pipeline investigates areas where we suspect wind or water erosion may have reduced the depth of ground cover over our pipelines so we can repair the depth of cover and maintain the safety of the pipe.

• Geotechnical Monitoring – The pipeline route is monitored for soil and ground erosion and movement during aerial patrol. If required any active slopes, streams and water bodies are monitored more thoroughly through a variety of survey techniques.

• Internal Inspections – In-line inspection, also referred to as ‘smart pigging,’ uses advanced technology to look for any locations where corrosion or changes to the pipeline may have occurred. These ‘smart pigs’ travel through the entire length of the pipeline collecting data. The data is then analyzed to determine if there are areas of concern requiring further investigation.

• Investigative Digs – Access Pipeline may conduct investigative digs based on the data and analysis obtained from the in-line inspections. If required, sections of pipeline may be excavated and inspected by qualified technicians to investigate their condition and to ensure integrity. Any issues found during these digs are repaired as needed.

• Valve Maintenance – Pipeline valves are located at regular intervals along the pipeline to limit spill volumes in the event of an incident. The placement of these valves is determined by many factors including the presence of water courses and to protect other sensitive resources.

We continuously monitor and improve our pipeline integrity programs through the use of new technology, innovations and applications.

environmentAl PrACtiCeSPrior to any ground disturbance, Access Pipeline ensures that site-specific environmental protection measures are incorporated to ensure equivalent land capability is maintained. This includes minimizing and mitigating effects on soil, water, wildlife, and vegetation. We make decisions we believe will have the least amount of impact on the environment.

We strive to use best engineering practices to minimize land disturbance during pipeline construction and soil handling. The safeguarding of the lands is an integral part of our values in minimizing potential impacts on the environment.
