Re: Clarington MSW incinerator C of A application


Dear Dr. King


Further to my previous correspondence with you  of May and July 2009 on the Clarington municipal waste incinerator which proposal is now in a period of public review of application for Certificate of Approval by the MoE:


Recent literature suggests that 15%  to  66% of Canadian women of reproductive age  already carry a body burden of mercury which is at Lowest Observed Adverse Effect Level.  (1, 2)


Paradoxically, current regulatory requirements in Ontario for the monitoring of toxic emissions into the air from industrial facilities for metals such as mercury  are very crude indeed.  Guideline A7 requires that air emission samples for these toxics be taken on one day each year.  (It must be challenging to perform statistical analysis on one data point.)


It therefore appears that although significant amounts of mercury and other toxics may be released from the proposed facility, regulators will effectively have no idea what those amounts are despite their claims for “continuous monitoring”. A better description would be “no meaningful monitoring at all”.


Given the current detailed understanding of the effects of metals and particulates on human health, and in the specific case of mercury the effects of that substance on the developing human fetus, it appears that this facility may pose a threat to the public health.  According to the literature previously cited body burdens of mercury in many pregnant Ontario women are already at the tipping point.


For these reasons and out of consideration of the public health  I again call on you to stop the construction of this potentially dangerous facility. Clearly there needs to be a review of Ontario air standards using the model established by Justice Dennis O’Connor for water quality standards some years ago.   As the Environmental Commissioner of Ontario has already noted,  current Ontario air standards are inadequate.  I and others have documented this elsewhere. The Clarington case is a good example.


Will you now stop this application for Certificate of Approval pending further review?


Sincerely yours,
