Extension of the gas network between Bellechasse and Montmagny

In recent years, the RCMs of Montmagny and Bellechasse as well as the local business community have mobilized to have the natural gas network extended to supply businesses and industries in the sector. In response to this action, and to support the regions’ economic development, the government provided $47.6M in financial assistance for the extension of the gas network from Saint-Henri-de-Lévis to Montmagny. The project consists of an 80 km extension of the natural gas distribution network.

The project at a glance

The arrival of natural gas in the region will result in an annual reduction of more than 2,000 tonnes of GHGs, in addition to significantly reducing emissions of air pollutants. Consumers could ultimately save $2 million in annual energy costs.

This gas network extension project will provide the Chaudière-Appalaches region with the infrastructure and potential to participate in Québec’s energy transition with the production and consumption of local and renewable natural gas.

The work will be carried out by the contractor Pomerleau.

Project route

The natural gas pipeline will be buried mainly in municipal road or Ministère des Transports du Québec (MTQ) rights of way. The municipalities served will be Saint-Henri-de-Lévis, Saint-Charles-de-Bellechasse, Saint-Raphael, Saint-François-de-la-Rivière-du-Sud and Montmagny.

For details about the route, click the following links to view maps of the eight areas that will be crossed: Saint-Henri-de-Lévis, Saint-Charles de Bellechasse, La Durantaye, Saint-Raphaël, Saint-Vallier, Saint-François-de-la-Rivière-du-Sud, Saint-Pierre-de-la-Riviève-du-Sud and Montmagny.

Traffic obstructions are to be expected. For narrower streets, only local traffic will be permitted, and detours will be put in place for other road users. Dedicated staff will direct traffic and ensure the safe travel of road users. In addition, the work will be carried out sequentially to minimize impacts on the entire project route.

Residents affected by the work done on their street will receive a letter to inform them more precisely of the impacts to be expected and the measures implemented to mitigate them. This web page will be available to monitor the progress of the work and to access information on the various obstructions to be expected.

Public information sessions had been scheduled for March 16 and 17 in Saint Charles-de-Bellechasse and Montmagny.

Because of COVID-19, they had to be cancelled in order to comply with the government’s recommendations regarding the pandemic.

That said, we want to stay in touch with the community before the work begins and to gather questions and comments.

Please note that the latest updates will be published on this Web page and that any member of the public who wishes to contact our team can do so by calling 1-844-483-1313 or emailing us.

This work is carefully planned, monitored and performed by our engineering and construction teams. Evaluations are also conducted so as to address specific concerns.

The risks of this type of work are no different from those found on any construction site. The “natural gas” factor only comes into play at the very end of the work, when the new pipeline is put into service. This type of work is performed regularly by our teams, who are trained in the use of safe procedures. In the event of an emergency, we are trained to respond quickly and effectively in collaboration with the emergency services.

Those wishing to be connected to the network can contact Énergir. Any connection must be analyzed in order to ensure its profitability, both for the customer and for Énergir.
Our development teams have been working in the field in recent months to support potential customers.

Natural gas

  • Natural gas is 95% methane (CH4).
  • Methane is produced in nature by living organisms and decomposing organic substances.
  • It is lighter than air and disperses into the atmosphere when released.
  • It is naturally odourless. We add mercaptan, a substance that releases a similar smell to rotten eggs, which makes it possible to detect it at very low concentrations in the air (less than 1%).
  • Natural gas is not toxic or water soluble.

Advantages of natural gas

By replacing petroleum products, natural gas helps to reduce greenhouse gases by 32%. Natural gas emits significantly fewer atmospheric pollutants and makes it possible to eliminate nearly all sulfur oxides (SOx) and nitrogen oxides (NOx), pollutants which are, among other things, responsible for acid rain and health problems.
  • 32% reduction in GHG
  • 99% reduction in SO2 emissions
  • 70% reduction in NOx emissions
  • 70% reduction in fine particulates
