Cornwall Ontario — There is an Air Quality Warning. On Monday, May 6th, starting at 9 am, Enbridge Gas will be purging their gas pipe line in Cornwall and it will be vented to the north at the St. Lawrence Gate Station located between St. Andrews and Power Dam Drive in Cornwall.

As such, the air quality may be affected during the venting process. It’s expected the process will last for about 8 hours throughout the day as mercaptan is released into the atmosphere. There is no direct risk to the public.
