24 North American Oil & Gas Pipelines | JULY/AUGUST 2 018 nominal pipe sizes and pressure systems, in the City of Kawartha Lakes, and the Township of Brock in the Regional Municipality of Durham, Ontario, to serve the community of Fenelon Falls. The pro- posed pipelines will be located within existing road allowances in the Study Areas and is expected to operate at a pressure up to 400 psi in some sections along the pipeline route and less than 20 percent of the specified minimum yield strength (SMYS). Seg- ment 1, known as the Sunderland Reinforcement Segment, will consist of approximately 8 km of 6-in. steel extra high pressure (XHP) pipeline, from Sunderland to Manilla, Ontario, where it ties into an existing Enbridge pipeline. Segment 2, known as the Distribution Pipeline to Fenelon Falls Segment (DPFF), will originate in Oakwood and travel north to the Fenelon Falls, for a total of approximately 29 km of a 6- and 4-in. XHP steel and 6-in. high pressure polyethylene natural gas pipeline. En- bridge applied to the Ontario Energy Board (OEB) for approval in July 2017. Construction crews broke ground in May, after Enbridge received $12.3 mil- lion from the province to bring the expansion to Fenelon Falls, but the expansion to Bobcaygeon re- mains uncertain. Construction on the Fenelon Falls portion of the project is expected to be complete in November. NEXUS Gas Transmission Project Location: Ontario Stakeholder(s): Enbridge Gas Distribution Inc. Overview: The proposed NEXUS Gas Transmission Project (NGT) is a joint venture among Enbridge, Spectra Energy and DTE Energy and is being devel- oped to support the growing demand for natural gas in the upper U.S. Midwest and eastern Canadian regions. With a decline in western Canadian natu- ral gas supplies to these regions, the proposed NGT system is designed to transport at least 1 Bcf/d of growing supplies of Ohio Utica shale gas to the high- demand markets in Ohio, Michigan and Ontario, Canada. The proposed path for NGT will consist of a newly constructed, greenfield pipeline that will extend approximately 250 miles from receipt points in eastern Ohio to interconnects with the existing pipeline grid in southeastern Michigan. Construc- tion is under way in Ohio. The pipeline is expected to be in service by the third quarter 2018. NGTL System Expansion Project (2021) Location: Alberta Stakeholder(s): NGTL, TransCanada Overview: In February, TransCanada announced plans to further expand its NGTL pipeline system. The company completed a large expansion of the same system in 2017. Now, TransCanada is explor- ing options to add approximately 350 km of new 48-in. pipe to the NGTL system in northwestern Alberta to help producers in the Western Cana- dian Sedimentary Basin (WCSB) get natural gas to market. These various pipeline sections within the study area would be located starting in Grande Prai- rie County, extending through the Municipal Dis- trict of Greenview No. 16, Yellowhead County and ending in Clearwater County. Multiple pipeline sec- tions would run parallel to the existing system and connect at each end to adjacent existing pipelines. The routes the company is investigating would be in three key areas: Grande Prairie West Area, Grande Prairie South Area and Edson South Area. Trans- Canada expects regulatory approval to come in the second quarter 2020, with an estimated in-service date a year later. North Montney Mainline Project Location: British Columbia Stakeholder(s): NGTL, TransCanada Overview: Located in Peace River Regional District of northeast British Columbia, the $1.4 billion North Montney Mainline (NMML) project includes a 301- km, 42-in. diameter pipeline and will also include metering facilities, valve sites and compression fa- cilities. The project is backed by 20-year commer- cial contracts with 11 shippers to transport approx- imately 1.5 Bcf/d of natural gas. In May, the NEB recommended the approval of variance applied for in March 2017. With construction beginning this year, the estiamted in-service date is April 2019.
