Latest updates: closure work at the dry material landfill site

28 novembre 2019

Pierrefonds-Roxboro, November 28, 2019 – In recent weeks, the Borough and residents of the neighbourhood have noticed that the odour episodes emanating from the dry material landfill site at the former Meloche quarry have been more intense and more frequent than before. Sensitive to this situation, which is causing inconveniences for a large part of the population in the West, the Borough has doubled its efforts to take the necessary steps with the responsible authorities, to get updates from them on the situation.

"Be assured that the Borough is sensitive to this situation and that we are closely monitoring the progress of the work with the organizations involved. We share the distress of our citizens and patience will be required until these mandatory operations are finalized. Until then, we continue to do our duty to inform you," said Borough Mayor Dimitrios (Jim) Beis.

As announced in a press release issued last September by the Borough, the closure of the GFL landfill site, under the supervision of the Ministère de l'Environnement and the Service de l'Environnement de la Ville de Montréal, has been underway for three months.

State of the situation

The contractor has begun drilling thirty-five (35) vertical wells to capture the biogases that are causing the odours perceived in the neighbourhood.

Attentive to citizens' concerns and because of the magnitude of the odours smelt, the Borough intervened with the authorities.

The new larger flare will be started during the winter of 2020, earlier than planned, thus after the drilling of the first fifteen (15) wells to try to mitigate the situation. In total, GFL expects that it will take approximately 18 months to complete the closure of the landfill site.

This week, the ministère de l'Environment et de la lutte contre les changements climatiques visited the site to assess the situation. Among other things, the ministry measured the concentration of hydrogen sulfide (H2S) and methane in some homes, and nothing was detected. In addition, the ministry visited the landfill site to verify that it was in compliance with the certificate of authorization issued in August. After verifications, the infrastructures are in compliance with the certificate of authorization.
