How are greenhouse gases emissions estimated and air quality evaluated to know if the new station will have any adverse impacts on public health? Is vehicle idling included in these assessments?

An air quality analysis was prepared to assess air quality and a greenhouse gas study to evaluate emissions was also completed for the station.  Emissions of criteria air pollutants (CAP) and greenhouse gases (GHG) associated with construction and operation of the project (including vehicle idling) were evaluated to determine if the project would cause significant air quality impacts. The Air Quality analysis concluded that the proposed project would not cause significant air quality or GHG impacts.

The Health Risk Assessment (HRA) assessed emission sources from the idling of vehicles queueing at the pumps and vehicle travel within the vicinity of the proposed project.  The HRA shows that the project’s potential health risks are below the applicable regulatory thresholds.  

Copies of the Air Quality analysis, Greenhouse Gas study and Health Risk Assessment can be found at Air Quality and Greenhouse Studies   Health Risk Assessment
