Unconventional gas development can affect local and regional air quality. The MECP summary and dispersion model states that CO2 emissions will exceed the Ministry's Limit by 300%. At a time when global warming is recognized as a real and present threat to the planet, the combined six greenhouse gas emissions from this plant 24/7/365 should be of concern. Even though the MECP dispersion model shows the six of the contaminants listed in the amended Environmental Compliance Agreement (ECA) were below the maximum Ministry Limits for each contaminant, the cumulative/combined effects of all of these on air quality and human health need to be calculated.
In addition, the ChemTRAC study (2019) found air releases of toxic non-cancer agents in our community are already the highest in all of Toronto. These would include pulmonary, cardiovascular and developmental toxicants among others. Coronation industrial Park was also among the areas with highest releases of cancer-causing agents. If the largest bio-gas plant in Canada is permitted to locate here, the combined / cumulative releases from the bio-gas plant, the six chemical plants and the wastewater treatment plant, will result in increasing toxic levels of the contaminants in local and regional air. an emission noted TRS/H2S is extremely toxic at low levels in air , and particulates/soot are one of the six chemicals that will be released by the bio-gas plant, and are toxic to health. Exceedances of the protective reference benchmarks for particulates were noted for 24 hr exposures in a human health risk assessment (intrinsik 2015) undertaken as part of an environmental assessment here. The trucks used in this operation are diesel meaning the levels of particulates will be even higher. these public health risks need to be formally assessed
