St. John Compressor Station Project

Update:  The Project will mobilize oversize loads starting the week of October 7 through October 31. This will entail the use of police escorts and periodic road closures on White Oak Avenue for short durations.

On Wednesday, October 9, the Project must start work at 6 a.m. This is required to complete the type of work scheduled for this day. The Project will make every effort to minimize any potential impacts of noise and lighting.

Starting October 14 through October 28, the Project will have additional work outside of our standard construction hours. Due to the extended hours, there may be noise and visible lighting in the evening. This is necessary due to the welding process that is required for this phase of the Project. We do not anticipate evening work to exceed 8 p.m.

This phase also entails an outage of our facility. To minimize impacts to our customers, including NIPSCO, the Project must work for longer durations. Once this two-week phase is complete, the Project will return to its standard construction hours.

Impacted road: We anticipate that this activity will impact primarily the roads of West 93rd Avenue and White Oak Avenue.

Road closure: We do anticipate periodic closures on White Oak Avenue for short durations. We will abide by the required hours issued in our hauling permits.

Update: The Project has completed its pre-construction preparation activities. Starting the week of August 26, the Project will begin foundational work at the site including excavating and the installation of helical piles. These types of activities will require multiple trucks to enter and exit the area during our project work hours over the next three weeks. 

Impacted road: We anticipate that activity will impact primarily the roads of West 93^rd Avenue and White Oak Avenue.

Road closure: We do not currently anticipate any road closures but will utilize flaggers as needed. 

Update: During the week of August 12, the Project will begin a full mobilization of equipment to our site. This will include the transportation of office trailers and heavy equipment. Most of the traffic flow will last approximately two weeks. 

Impacted road: We anticipate that activity will impact primarily the roads of West 93rd Avenue and White Oak Avenue.

Road closure: We do not currently anticipate any road closures but will utilize flaggers as needed. 

Update: During the week of August 5, preliminary construction preparation will continue at our Project site. This will include the continuation of slit trenching and hydrovacing. These activities are required to safely excavate around utilities and will produce noise during the work hours of our Project. 

The Project also anticipates beginning the mobilization of office trailers. 

Impacted road: We anticipate that activity will impact primarily the roads of West 93^rd Avenue and White Oak Avenue.

Road closure: We do not currently anticipate any road closures but will utilize flaggers as needed.

Update: Preliminary construction preparation will continue at our Project site. During the week of July 22, we anticipate the start of slit trenching and hydrovacing. These activities are required to safely excavate around utilities and will produce noise during the work hours of our Project.

Impacted road: We anticipate activity will impact White Oak Avenue as select heavy equipment mobilizes to our Project site in addition to the commute of our contractors.

Road closure: We do not currently anticipate any road closures.

Update: Construction activity will begin on June 24 with dump trucks moving materials to and from the Project site.

Impacted road: We anticipate activity will impact White Oak Avenue.

Road closure: We do not currently anticipate any road closures.

We’re a team of 7,000+ energy problem solvers working to move, generate and store the energy North America relies on. Today, we are taking action to make that energy more sustainable and more secure. We are innovating and modernizing to reduce emissions from our business, and we are delivering new energy solutions – from natural gas and renewables to carbon capture and hydrogen – to help other businesses and industries decarbonize too. TC Energy is an energy infrastructure company that for more than 70 years – and in this area, over 100 years – operated pipelines, storage facilities and power-generation plants that support life in the U.S., Canada and Mexico safely, reliably and quietly.

No. Solar Turbines is the manufacturer of the compressor unit turbines, but they are not solar powered.

By replacing the seven existing reciprocating compressor units with three modern Solar Turbines units, we can improve operational sustainability, decrease vibration, reduce greenhouse gas emissions and operational sound levels, while gaining maintenance and operational efficiencies and improving the reliability, safety and long-term integrity of the St. John Compressor Station and ANR’s Pipeline System.

Replacement and modernization of older compressor units with more efficient units and modern technology will result in decreased emissions.

TC Energy’s ANR Pipeline System and related metering and compressor stations have operated safely for the more than 70 years. Safe and efficient natural gas delivery is a foundational value for TC Energy and its employees. Through more than a century of operating experience and technological advancement, we have developed one of the safest and most reliable energy transportation networks in the world. We monitor our system 24 hours per day, seven days per week, and are constantly utilizing the latest in technology to maintain the highest possible integrity standards.

New compressor station units and construction activities will be located on the existing St. John Compressor Station site. Construction will use a temporary workspace.
