On January 7, 2008, Toronto Public Health published a consultation document for a proposed environmental reporting and disclosure program. This program would require (through a by-law) certain facilities to report annually to the City of Toronto if they use more than a certain amount of one or more of 25 priority substances, including benzene, lead, particulate matter 2.5, nitrogen oxides, polycyclic aromatic hydrocarbons and trichloroethylene. This information would be made publicly available, for the purpose of facilitating pollution-prevention measures. Unless a facility is exempted, the by-law (as described in the proposal) would require reporting by any facility that uses (i.e., manufactures, processes or otherwise uses) or releases more than a certain amount (generally 100 kg or more per year) of any of the designated substances. According to the proposal, the by-law would not apply to certain facilities within exempted sectors (e.g., individual residences) or with exempted emissions sources (e.g., emissions from space heating). Toronto Public Health is accepting comments on the proposal until February 6, 2008. For more information, please see  www.toronto.ca/health/hphe/enviro_info.htm.
