OEHHA, the State regulatory agency overseeing the administration of Propositon 65, has announced its intent to list "emissions from the combustion of coal" as a carcinogen. See http://www.oehha.ca.gov/prop65/CRNR_notices/admin_listing/intent_to_list/noil060713coal.html. The emissions at issue are both from industrial facilities and residential settings. According to the American Lung Association, these emissions include acid gases (hydrogen chloride, hydrogen fluoride, Dioxins & Furans (e.g., 2,3,7,8-TCDD), methylmercury, metals (arsenic, beryllium, cadmium, chromium, nickel, selenium, manganese, lead), Polynuclear Aromatic Hydrocarbons (PAH's), radioisotopes (radium, uranium), and volative organic compounds (e.g., benzene, toluene, ethylbenzene, xylene, aldehydes [including formaldehyde]). See http://www.lung.org/assets/documents/healthy-air/coal-fired-plant-hazards.pdf.
OEHHA is citing to the "authoritative bodies" listing mechanism for the listing. [For a discussion of Prop. 65 and the various listing mechanisms, see http://www.rmkb.com/tasks/sites/rmkb/assets/image/253.pdf as well as prior posts discussing the mechanism.] The authoritative body is IARC, as manifest in its 2010 Publication Household Use of Solid Fuels and High Temperature Frying. See http://apps.who.int/bookorders/anglais/detart1.jsp?sesslan=1&codlan=1&codcol=72&codcch=95, pp. 225, 226, 303, and 307. The monograph notes that "[t]here is sufficient evidence in experimental animals for the carcinogenicity of emissions from combustion of coal."
OEHHA sent out requests for information relevant to the possible listing on March 26, 2013. Input was requested by May 14, 2013. There were no responses.
OEHHA is providing a second opportunity to provide relevant information on the possible listing. Comments are due by 5 PM on July 8, 2013. See http://www.oehha.ca.gov/prop65/CRNR_notices/admin_listing/intent_to_list/noil060713coal.html.
