EBR #010-7124 – McAsphalt Industries Limited Approval for discharge into the natural
environment other than water (i.e. Air) – EPA s. 9

Lake Ontario Waterkeeper is writing in response to the above-noted proposal by
McAsphalt Industries for an amended site-wide Certificate of Approval for their facility in
Oshawa.

The facility is located at 1221 Farewell Street in Oshawa, on a point of land jutting out into
Lake Ontario. It is situated between the Oshawa harbour and an undeveloped piece of
land that includes Gifford Hill and the protected Second Marsh. McAsphalt has applied for
a Certificate of Approval to install a Delta Cooling Tower and a Torit Dust Collector on site.
According to the Emissions Summary Dispersion Modelling Report (ESDM), the facility
emits particulates, nitrous oxides, hydrochloric acid, volatile organic compounds (VOC’s),
fuel oil, 1,2,4-trimethylbenzene, benzene, ethylbenzene, hexane, toluene, and xylene.

Lake Ontario Waterkeeper submits that site-specific air modeling for the McAsphalt facility
must be completed, including a consideration of the effects of shoreline fumigation, before
the Ministry of the Environment can make a decision on this proposal that complies with
the SEVs.
