Medicine Hat Looping Project

Background

The Nova Gas Transmission Ltd. system (NGTL) consists of more than 25,000 km of natural gas pipeline and associated facilities located in Alberta and northeastern British Columbia. NGTL has over 1,100 receipt points and over 300 delivery points. The average daily capacity is 16,800 million cubic feet per day. The system came under Canada's National Energy Board jurisdiction in 2009 and is wholly-owned by TC Energy. [1]

NGTL is divided into three areas: Peace River, North and East, and the NGTL Mainline. Throughput information is provided for these areas as Upstream James River, North and East Flows, and Eastern Gate, respectively. The Upstream James River's primary receipt points are Northwestern Alberta and Northeastern B.C. Its primary delivery points are Intra-Alberta and the AB/BC border. Its average daily capacity is 8,000 million cubic feet per day. [1]

The North and East Flow primary receipt points are North and East Alberta. Its primary delivery point is Intra-Alberta. Its average daily capacity is 4,300 million cubic feet per day. [1]

The primary receipt point for Eastern Gate is Intra-Alberta, and the primary delivery points are McNeill and Empress. Its average daily capacity is 4,500 million cubic feet per day. [1]

Leaks

The NGTL system suffered a rupture on its pipeline system 138 km (85.6 miles) west of Fort McMurray, Alberta on October 17, 2013. TC Energy's gas control center detected a drop in pressure on a section of its north-central corridor natural gas pipeline between its Wooden House and Buffalo compressor stations. The size and cause of the leak was unknown at the time of publication.[33]

Expansion Projects

2017 NGTL System Expansion project

The 2017 NGTL Expansion added 230 kilometers of pipeline and two compressor stations. According to TC Energy, the project included five separate pipeline loops and two compression stations. The project cost an estimated $1.3 billion.[7]

The project faced significant resistance:

Saulteau First Nations v. Canada (A-G), Nova Gas Transmission, and the NEB/Blueberry River First Nations v. Nova Gas Transmission, and Canada (A-G)

Both the Blueberry River and Saulteau First Nations sought to bring the National Energy Board's approval of NOVA Gas Transmission Ltd.'s pipeline expansion into north-eastern British Columbia under judicial review. Both of the First Nations claimed that they were warranted a judicial review request due to being inadequately consulted about the project while also stating that the National Energy Board lacked jurisdiction to approve of the pipeline project. However, the Federal Court refused their request and did not provide a reason for its decision.[34]

Bigstone Cree Nation v. Nova Gas Transmission Ltd. and Canada (A-G)

In 2015, the Bigstone Cree Nation, consisting of 7,752 members, filed an application to judicially review the National Energy Board's decision to approve Nova Gas Transmission Ltd.'s expansion of the NGTL pipeline system. The core of Bigstone's argument centered on the lack of proper consultation given to the First Nation regarding the project, thus violating their constitutionally protected and established treaty rights along with enshrined indigenous title and rights. Because Bigstone never had any direct consultation with Nova, there could be no possible mitigation of potential negative effects on the First Nation's intersts, nor could there be any serious accommodation of the indigenous group's needs. The band thus concluded that the National Energy Board should not approve of the project "because it cannot reasonably determine that the Project is not likely to cause significant adverse effects, or that any significant adverse effects can be justified in the circumstances."[35] Although a judicial review was granted, the National Energy Board has thus far kept up its approval of the NGTL pipeline system expansion and the project is currently under construction.[36]

In the hearings, Bigstone also indicated concerns regarding the potential contamination of traditional foods, medicine, and agricultural food crops resulting from pesticide and herbicide use and wanted to see the limitation or elimination of chemical applications. The First Nation also provided oral traditional evidence of the deleterious effects of extraction-based industry in its territory. Bigstone stated that it had witnessed the loss of whole herds of caribou, moose, deer, and other wildlife in the region and that it is becoming harder to gather the water and medicine in the area of development. Bigstone has focused on Caribou habitat and population restoration in recent years, which could be threatened by the NGTL project according to the group. Bigstone claimed that NGTL's mitigation measures were inadequate and did not address the First Nation's unique rights and interests. Bigstone also argued that the National Energy Board failed to comprehend the cumulative environmental effects of the project in its assessment.[37]

Alternative Resistance Strategy

In 2017, the Bigstone Cree Nation planned to install gates along with sentries at the edge of its territory to prevent the entry of Oil and Gas companies into their territory, along with other companies contracted to work with them. The reasoning for this plan was due to the failure and exhaustion of all other civil and legal means to "end the unjust enrichment of Multi-National Corporations." TC Energy was just one of the companies to be blocked from entering the First Nation's territory.[38] The First Nation gave the following reasons:

-The abandonment of the local economy and local companies -Disregarded Impact Benefits Agreements with Oil/Forest/Mineral Industries -Failed meaningful consultation between Oil/Gas and Mineral Industries and the ACO -Surface and Ground Water Protection - Wabasca Watershed including Aquifers -Delayed Transfer of Treaty Entitlement Lands to the Nation -Neglect of a referendum in the Transfer of Admin. And Control of Highways[38]

However, less than a month later, the Bigstone Cree Nation withdrew their plan to construct gates at the entry points to their territory. Instead of essentially creating a roadblock, Chief Auger of the Bigstone Cree Nation told reporters that they may construct tolls to generate revenue from the companies travelling through their territory. Despite the change of plans, companies like Exact were still pulling out of the area due to the unpredictable situation. Chief Auger was not worried about various companies pulling out, since the conditions were already so dire that he likened it to "living in a third-world situation." Auger also stated that "Nobody should have control of our land. It's our land."[39]

The Government responded through the Ministry of Indigenous Relations, declaring that they will "make every effort to prevent the establishment of toll gates." Auger said he was still standing firm on the idea of tolls and would further discuss the plan with the community. Auger also stated that "No government comes and tells us what to do — federally, provincially, municipally, or even for that matter, oil companies."[39]

In total, there are four expansion projects to the system, the 2017, 2018, 2019, and 2021 expansion project.

In October 2018, TC Energy announced that NGTL system would begin commercial operations in 2021 and 2022.[40]

In February 2020, federal regulators approved the expansion project.[41]

In December 2020, Natural Gas Intelligence (NGI) reported that Nova Gas Transmission Ltd. (NGTL) described the Canadian natural gas industry as facing a "high degree of uncertainty". According to developers, "System flow requirements in the 2024-2025 portion of the design horizon have a high degree of uncertainty due to the influence of major market factors that are still too early in their development to predict." NGI further stated that "Political and economic risks jeopardize up to C$3 billion ($2.3 billion) of additions that the pipeline network would build if the industry fulfilled its potential, management said in a new edition of NGTL’s annual five-year capital plan."[42]

2018 NGTL System Expansion project

The 2018 expansion would add 55 miles and 2.7 billion cubic feet per day capacity to the Alberta and British Columbia area. The expansion includes construction of pipeline, one new compressor, new and expanded meter stations, and other associated facilities.[10]

There have been no development updates since 2017 and the expansion project is presumed to be cancelled.

2019 NGTL System Expansion project

Proposed to be operational in 2019, this expansion would add 171 miles and 3 billion cubic feet per day of capacity to the Alberta and British Columbia area. The project includes construction of pipeline, compression enhancements at five compressor stations, new meter stations and other associated facilities.[10]

There have been no development updates since 2018 and the expansion project is presumed to be cancelled.

West Path Delivery Program expansion project

TC Energy proposed four projects as part of its West Path Delivery Program within Alberta and British Columbia. These projects are to supply natural gas produced in western Canada to growing demand in southwest Alberta, southern British Columbia, and downstream North American markets.[43][17][21] The four projects - Foothills Zone 8 2022, Foothills Zone 8 2023, NGTL 2022, and NGTL 2023 - are all operating as of 2023.[18]

North Corridor Expansion project

The North Corridor Expansion project is intended to expand pipeline capacity for natural gas from the Peace River Project Area to markets in northeastern Alberta, Canada.[23] It consists of four sections: NCC Loop (North Star Section 1), NCC Loop (North Star Section 2), NCC (Red Earth Section 3), and NWML Loop No.2 (Bear Canyon North Extension Section). The entire project was in-service as of 2023.[23]

2021 NGTL System Expansion project

The 2021 NGTL System Expansion added 214 miles to the system, stretching from Grande Prairie, Alberta to Municipal District of Greenview No. 16 to Yellowhead County, Alberta, to Clearwater County, Alberta, Canada.[29]

In May 2021, Macro Enterprises Inc. said that it had signed a contract to construct the Deep Valley South and the Colt sections of the expansion.[44] This development update indicated that expansion plans were ongoing, despite developers sighting uncertainty in their proposed pipeline projects.[42]

As of Q2 2024, all project components has been placed in-service.[28]
