Impacts on the inhabited area and human activities
♦ Recommendation 11 — The Panel recommends that the proponent ensure a
proper follow-up, after reaching agreement with the ministère du Développement
durable, de l’Environnement et des Parcs with the purpose of assessing the true
level of additional air pollutants from the project compared to existing levels within
the area currently retained for the planned project.
Air quality follow-up
The Panel concludes that it is important that an overview of the quality of ambient air
be established for inhabited areas during LNG terminal operation so as to protect
human health and not to harm the margin of manoeuver needed for new
developments in this area. To this end, the Panel supports the recommendations
made by Health Canada and the Agences de la santé et des services sociaux de
Chaudière-Appalaches and de la Capitale-Nationale to carry out an air quality followup
in the residential areas closest to the proposed terminal facilities. (DB104, p. 10;
DM602, p. 74).
On one hand, such oversight would make it possible to more accurately assess the
project’s relative influence on degradation of air quality by the addition of air
pollutants, such as sulphur dioxide, and, on the other hand, to determine the
remaining margin of manoeuvre for future development of this part of Lévis. This
follow-up approach would definitely allow identification of future at risk contaminants
and suggest the needed steps for control measures at the source to maintain a
healthy air quality environment for the surrounding population.
♦ Recommendation 12 — The Panel recommends that the ministère du
Développement durable, de l’Environnement et des Parcs add a new sampling
station to its network to show air quality in Lévis. If the project goes ahead, the Panel
recommends that the proponent establish a monitoring station in the inhabited area
between the jetty and Highway 132 together with the ministry.
♦ Recommendation 13 — The Panel recommends that the data collected from air
quality samples taken at the monitoring station operated by the proponent in the
inhabited area most exposed to the project’s emissions be analyzed in concert with
the ministère du Développement durable, de l’Environnement et des Parcs. Sources
of recurring exceedances that go beyond the Québec standards in force must be
corrected to the ministry’s satisfaction.
