Critical Notices Show Notices List. All regulatory agencies (local, provincial, and federal) had been notified of the occurrence. The assessment also identified that, due to the lapse of time between runs of in-line inspections on the 4AL2segment, there was greater uncertainty when it came to the actual defect size due to the use of an assumed growth of a potential defect over a longer period of time. The Board authorized the release of this report on Spectra was formed in late 2006 from the spin-off from Duke Energy. Enbridge notified FortisBC of the pipeline rupture. On 23October2018, the NEB specified modified and additional measures, including the operation of the NPS36L2 (from Station2 to Huntingdon Meter Station) with a restricted operating pressure of 80% of its 60-day high pressure. Halfway River First Nation, Kitselas First Nation, Kitsumkalum First Nation, Lake Babine Nation, Lax Kwalaams The U.S. Department of Transportations Pipeline and Hazardous Materials Safety Administration (PHMSA) provides online maps to help you locate pipelines in or near your community through theNational Pipeline Mapping System(NPMS). Charpy impact energy values were within the range typical for GradeX60 steel.Footnote 10 The microstructure and microhardness values were within a typical range for GradeX60 pipe steel. This can be a useful piece of information to correlate with the presence of cracks in the pipeline. On 16November2018, NB-001-2018 (AmendmentNo. 05February2020 The emergency response activities were successful in mitigating the impacts of the occurrence. On Feb. 28, the company was permitted to proceed with the transaction under the Hart Scott Rodino Antitrust Improvements Act of 1976. Improvements were also made to the emergency response program to clarify expectations for engaging potentially affected stakeholders in emergency response exercises, and to track invitations and participation of potentially affected stakeholders during future full-scale exercises. Westcoast Pipeline - Wikipedia Some of the SCC will continue to grow as a consequence of the near-neutral pH environment and mechanical forces. The emergency planning zones determine the evacuation areas and take into account the location of access routes, power lines, pipelines, and fire and explosion hazards. The critical crack sizeFootnote 25 was also calculated using the hydrotest pressure, which is defined as 125% of the maximum operating pressure, to determine the maximum allowable crack depth. To ensure that CP systems remain effective at preventing corrosion, regular monitoring is done by measuring the pipe-to-soil potential using a reference electrode and a CP test station that is electrically connected to the pipe. about how we plan to meet these goals, please visit enbridge.com/esggoals, WCGT Ltd. will work collaboratively with Indigenous groups, stakeholders and interested parties to discuss Since its original construction, the 4AL2segment had been internally inspected multiple times using various types and generations of SCC in-line inspection technologies. On 26 June 2019, the TSB sent Pipeline Safety Advisory 02/19 to Enbridge Inc. (Enbridge) on the management of stress corrosion cracking (SCC) on susceptible pipelines. Imperial Oil Ltd. Koch Canada .

Westcoast Transmission Co. - LiquiSearch more The Westcoast 4AL2 ruptured sections of pipeline were examined to determine the mechanical properties of the pipeline and its mode of failure. LP101/2019 Pipeline Failure Review of pipeline failure analysis. However, in the time between the pipeline rupture and official notification by Westcoast, several of the local communities took the precaution of self-evacuating. The CP system on the NPS36L2 pipeline provides current for all 3 of the pipelines in the shared right-of-way because they are electrically bonded together. A second section (labelled as section2 in Figure5) was cylindrical in shape, slightly compressed, with the appearance of tearing at the end. Enbridge Inc. support planning and design of pipeline water crossings along the proposed route(s). The analysis will focus on the condition of the pipe, the integrity of the pipeline, the integrity management systems used for mitigating stress corrosion cracking (SCC), and emergency response. CEPAs recommended practices for managing near-neutral pH SCC provides crack growth rates experienced by 2historical SCC failures that occurred on 36-inch pipelines. Operator contact information typically includes the operators name, product transported, contact name and phone number. In 2021, this natural gas transportation network delivered about 27.6 trillion cubic feet (Tcf) of natural gas to about 77.7 million consumers. It includes the description of the project, proposed deviation, and rationale for the deviation. In general, the majority of local emergency response plans are developed independently of the emergency response plans for federally regulated pipeline companies. The occurrence took place in hilly, forested provincial Crown land in a remote area about 13km northeast of Prince George, BC (Figure1). P11H0011 On 19February2011, TransCanada PipeLines Limited (TransCanada) Line100-2 experienced a natural gas pipeline rupture, fire, and explosion near Beardmore, Ontario. Maps - U.S. Energy Information Administration (EIA) The Lheidli Tenneh First Nation reserve, other communities, and operators of other pipelines near the 4AL2pipeline segment were not included in any of Westcoasts emergency response exercises between 2014 and 2018. The acquisition of Westcoast Energy reflects our strategy of owning and operating a portfolio of energy assets, trading around those assets and sticking with what we do best - energy.". It was confirmed that a natural gas pipeline rupture** and ignition had occurred on the NPS36L2 pipeline. The British Columbia Environmental Assessment Office (BC EAO) issued a Certificate for the WCGT Project on Furthermore, Westcoasts integrity management practices were examined to verify that regulatory requirements were being met. improvements to the in-line inspection process itself, and verification and validation of tool performance to align with American Petroleum Institute standard API1163; and. The NPS36L2 pipeline parallels the Westcoast NPS30L1 pipeline throughout the T-South sub-system in the same right-of-way. Third-party deliveries of natural gas are made throughout BC as well as to the U.S. Pacific Northwest through Huntingdon, BC. CER - Pipeline Profiles: Westcoast or BC Pipeline McMahon personally began lobbying the Canadian and American governments to remove their restrictions on the export and import of natural gas. Federally regulated pipeline companies are also required to perform full-scale emergency response exercises every 3years. 'Region' : 'All', Time magazine called him "The man who did the most to open up northwest Canada's wildernessand convince oilmen of its treasures." [1] If pipeline emergency response exercises are not conducted periodically with all potentially affected stakeholders, gaps in emergency response plans for the responders or for the local communities may not be identified, increasing the risk that all parties will not be sufficiently prepared to respond to a pipeline emergency. The period of time between the installation of the pipeline and the disbondment of the tape coating is referred to as the incubation period. The rupture had originated at stress corrosion cracks on the outside surface of the pipe, consistent with near-neutral pH SCC. With this information, it was determined that data originating from the 2003 inspection would be used in calculations to determine the next in-line inspection interval for that segment. Your personal information is collected when you voluntarily complete an online application, request form, or survey and is used in the same manner as any other personal information we collect in the course of providing services to you or responding to requests.

The Westcoast Connector Gas Transmission Project approved in the Environmental Assessment Certificate includes the potential to build two 48-inch diameter natural gas pipelines within the same right-of-way along with accompanying compressor stations that could potentially service multiple Liquefied Natural Gas (LNG) terminal sites starting at. The NEB's most recent audit of Westcoasts regulated activities began in November2012; the final report was released in March2013. The pipeline was returned to service on 13November2018. The 1stsection is completed by the regional office requesting the deviation (deferral) or waiver. 'longevity' : '', There was a small stream east of the crater. The NEBs Onshore Pipeline Regulations, 1999 require a company to develop, implement, and maintain a management system that includes an integrity management program and an emergency management program. The NEB works in collaboration with other federal government institutions, provincial and territorial emergency management organizations, first responders, other stakeholders, and communities in support of the overall emergency management system across the country. Westcoasts SCC Hazard Management Plan focusses on verifying the detection and discrimination ability of the EMAT in-line inspection tool. B.C. Environment Minister to Decide Fate of Enbridge's Westcoast Gas Emergency response planning at all levels of government and communities is key to ensuring that a response to an emergency occurs in a way that is organized and safe. For more information, please read our privacy statement. An emergency planning zone of 1km around the occurrence location had initially been established, but it was determined that there were no residents in this zone. our The rupture originated at stress corrosion cracks on the outside surface of the pipe. Because the in-line inspection interval had been set for 9years, based only on the cracks detected in the previous EMAT inspection, stress corrosion cracks that were below the detectable limits of the EMAT tool continued to grow over time until the failure occurred. The aim of the exercise was to emphasize the importance of Westcoast employees being able to respond to emergencies at compressor stations that were not part of their regular assignments. Westcoast Connector Gas Transmission Project - Global Energy Monitor However, it does not contain information for all member pipelines, only the members who have supplied information. Pipelines and electric transmission; Power plants; Resources: coal, oil and gas, shale, tight gas, biomass, geothermal, photovoltaic solar, wind; . The pipeline was further protected from corrosion using an impressed current cathodic protection (CP) system. In addition to the wholly owned transmission pipeline systems of DEGT (Texas Eastern Transmission, Algonquin Gas Transmission and East Tennessee With respect to the specific workstream related to documenting appropriate technical justification for any in-line inspection deferrals, a formal, independent review and approval, as well as tracking of in-line inspection deferrals, was established as a performance metric to ensure the process is being followed. On 01November2018, repairs were complete: the NPS36L2 pipeline was returned to service with a restricted operating pressure of 80% of its previous 60-day high pressure, as approved by the NEB. There was also electrolyte and corrosion product under the disbonded coating. The nearest private property is 500 to 600m west of the occurrence location. A detailed overall risk assessment of Westcoasts Canadian Gas Transmission System was completed in October 2018. More than . Emergency management has 4interdependent components: According to Public Safety Canada,Footnote 29 emergency planning should use a risk-based approach that addresses all potential natural or human-induced hazards. Knowledge-based performance is largely conscious, occurring as an individual learns new situations and outcomes. Regulated companies develop integrity management programs tailored to their specific operations and take corrective action as required, in compliance with applicable provisions and criteria set out in CSA StandardZ662-15. These Indigenous groups include Blueberry River First It did not consider stress corrosion cracking that was below the in-line inspection detection threshold, nor the possibility of an increase in crack size due to crack coalescence. Westcoast holds an emergency response plan training exercise in each geographical area at least once a year. [8], Enbridge has proposed a "reliability and expansion program" which would entail replacing old compressor stations, adding an additional compressor station, and other maintenance activities. As this was greater than the maximum interval of 9years, the next in-line inspection was scheduled for 2017. fluctuations in the environmental conditions surrounding the pipe; a susceptible high-strength steel pipe; and. West Coast Pipe - 2180 N. Locust Ave. Rialto, CA 92377 - ph: (909) 356-5670 fax: (909) 356-4229 . Data based on the most severe of the 9cracks was used to calculate an in-line inspection interval of 5yearsFootnote 24 for the 4AL2segment. These actions, in conjunction with an overall milder-than-normal winter season, helped avoid sustained service disruptions during the winter period. A remote sectioning valve (at KP32.6) was closed. The two sections of pipe that were ejected from the crater and the two fracture ends were transported to the Acuren laboratory in Richmond, BC. improvements to how reported in-line inspection anomalies are processed. Westcoast had scheduled the next in-line inspection for the NPS36L2 pipeline for 2017. Despite the absence of a completed waiver form, the in-line inspection for 4AL2 was deferred until fall2018. vast areas of unceded Indigenous Traditional lands. It was identified that this zone did not include any residents. Residents receiving gas supplied through the Westcoast T-South system south of Compressor Station4A were asked to conserve their use of gas during the winter as a result of this occurrence. Lastly, the companies were notified that the public utility subsidiaries of Westcoast Energy would be exempted from the Public Utility Holding Company Act, as amended, by the U.S. Securities and Exchange Commission following closing of the transaction. From 2002 to 2007, it was owned by Duke Energy of Charlotte, North Carolina. The fire extinguished itself once the pipeline was isolated and vented. The safety of the residents was not affected during the evacuation process in this occurrence. The nearest private property is located 500 to 600m away. Enbridge demands emergency extension for Westcoast pipeline - Dogwood pipeline you've never heard of Enbridge's Westcoast Connector. 'published_date' : '2002-03-14', About 140.72MMscf of natural gas from the pipeline was combusted as a direct result of the occurrence. The NEB monitors the effectiveness of each companys program using audits and compliance verification activities to ensure that pipelines and associated facilities are suitable for continued safe, reliable, and environmentally responsible service. Westcoast carried out a soil and water monitoring program in 2018 and 2019 that confirmed there were no lingering contamination sources and no offsite risk.Westcoast will continue to monitor for erosion and sediment control in 2020. Following the occurrence, Westcoasts response included isolating and shutting down the affected pipelines, installing roadblocks for public protection, and informing its stakeholders. Spectra Energy - Wikipedia Westcoasts emergency response plan was activated. Remember to always call 811 or your local One-Call center to have pipelines located and marked before digging. A 1-year extension would bring the in-line inspection interval to 10years, which would still be below the 12-year interval calculated by the crack growth rate model (which was based on a hydrotest pressure of 125% of the maximum operating pressure). There were no injuries. As such, the predicted growth that was used in the model was less than the actual crack growth. had not demonstrated that it had developed or implemented procedures to analyze incident data to identify trends, systemic issues, and opportunities for improvements; had not accurately tracked or reported key performance indicators; and. The crack characteristics were consistent with near-neutral pH SCC (Figure8). Westcoast's transmission system is composed of two parts: T-North which is north of Station 2 just west of Chetwynd (deliveries to NGTL and T-South) and T-South south of Station 2 (deliveries to BC Lower Mainland and the Huntingdon export point). combination.". T-North connects to NGTL at two points: Nova Gordondale and Sunset/Groundbirch. The Western NPS12 pipeline is in the middle, about 5m west of the NPS36L2 pipeline. [7] In 2019, the affected First Nation filed a lawsuit seeking a permanent injunction which would prevent Enbridge from operating the pipeline in their territory and reserves, and require the company to dismantle the pipeline and restore the affected lands to their natural state. Westcoasts emergency response plan involves performing various types of simulated emergencies and may involve mutual aid partners and regulatory agencies. West Coast Transmission - Archive-It This allows Westcoast to evaluate the confidence in the tools ability to detect a crack. A substantial amount of data was collected, along with Local communities need to assess whether they are affected by hazards associated with a pipeline emergency. Jericho's Proved Developed Reserves Up 32 Percent in Value. Westcoast Pipeline - Wikiwand This skill development process is important for when the individual is required to perform in an emergency while under stress. "With Westcoast's tremendous assets and our leadership team's invaluable experience operating in Canada, we're positioned to maximize our investment from the outset.". At the time of the occurrence, the sky was cloudy and the temperature was approximately 0C. The T-South system and the NPS36L2 pipeline loop extend 917km from Compressor Station2 to the Huntingdon Meter Station in Huntingdon, BC. In addition to cracks, EMAT tools can detect coating disbondment. Westcoast, which does business as Spectra Energy Transmission (Spectra), became a wholly owned subsidiary of Enbridge Inc. (Enbridge) following Enbridges merger with Spectra in February2017. This application provides the approximate pipeline location information along with general hazard recognition and response information for five pipelines closest to a specific location. An analysis of all available pipeline data is then done to prioritize the susceptibility of pipeline segments to near-neutral pH SCC. This document applies to the Westcoast pipeline system and is designed to address the safety and loss management of near-neutral pH SCC on the Westcoast pipeline system. The National Pipeline Mapping System (NPMS) Public Viewer from the Pipeline and Hazardous Materials Safety Administration allows users to view pipelines and related information by individual county for the entire United States. terminal sites starting at Cypress in northeast BC and ending at Ridley Island on the north coast. Over the past couple of years, WCGT Ltd. has been unable to conduct that necessary fieldwork due to restrictions relating to the pandemic, and from provincial permitting delays. This type of coating has a tendency to separate (disbond) from the pipeline, allowing moisture present in the soil to contact the pipe surface and shield it from the CP current. History If individuals do not learn sufficient knowledge and rules, they may not know how to understand or deal with certain scenarios, including emergency scenarios Footnote 34 , Footnote 35. characterization and mitigation of SCC, and, prepare local emergency response plans that reflect the assessment of the relative risk of occurrence of a hazard, periodically update the local emergency response plans, and. The map includes: Gas and hazardous liquid pipelines Liquefied natural gas (LNG) plants Hazards that could be present within a community, such as those related to the presence of a pipeline, require an emergency response plan. make this acknowledgement in gratitude and thanks to those whose territory we reside on or are visiting. In locations where remediation was required on more than 100m of pipe, a pipeline replacement or recoating was performed. As such, the predicted growth that was used in the model was less than the actual crack growth. The Board determined that failure of this section of Line100-2 pipe was the result of longitudinally oriented, near-neutral pH SCC, which was trans-granular in nature. [1] Although nobody was hurt in the explosion, and no property was damaged apart from the pipeline itself,[1] the explosion led to shortages of natural gas in British Columbia. This process was well established at Westcoast and had been used appropriately on other occasions. The risk assessment determined the type of inspection required, the frequency of inspections, and any pipe replacements, repairs, or upgrades required in high-risk scenarios. Natural Gas) and the wholly owned transmission systems of the former Westcoast It takes place on the external surface of susceptible pipe and can grow in both depth and length (circumferentially or longitudinally). The area affected by the fire that resulted from the pipeline rupture covered about 52000m2 (Figure 4). The 4AL2segments crack growth rates were calculated by Westcoast using the data received from the previous EMAT in-line inspections in 2003 and 2008, which had shown very little SCC activity. 'industry_sector' : '', Westcoast uses the Incident Command System to manage a response to an emergency. Download this investigation report in PDF, See other information related to this investigation. In 2016, about 1year prior to the scheduled EMAT in-line inspection run, a request to defer that inspection by 1year was noted in Westcoasts inspection tracking tool. . Earlier this month, the acquisition gained the approval of Industry Canada as it relates to the Investment Canada Act. began a small environmental field work program, predominantly focused on the eastern extent of the proposed The pipeline runs along a 299-mile corridor from Blaine, Washington to Portland, Oregon. Following the occurrence, Westcoast notified its customers that all natural gas flow on the Westcoast T-South system would be cut off until service could be restored. The NEB determined that no enforcement actions were immediately required. It was decided to shut down the pipeline. A local technician arrived at the4AL2 segment valve site near Landooz Road (kilometre post [KP]32.6) to investigate. The primary purpose of the external coating is to protect the pipe surface from its external environment. There was no damage to private property as a result of the rupture and fire. Houston-based Duke Energy Gas Transmission will operate the former Westcoast transmission, storage and distribution systems. Deficiencies found through the assessment were prioritized and the mitigation controls assessed to maintain fitness for service. Pipeline rupture and fire The Transportation Safety Board of Canada (TSB) investigated this occurrence for the purpose of advancing transportation safety.
