Dioxin pollution and tire burning cement plants

From NEIL J. CARMAN, PH.D. Clean Air Program Director and former Texas Air Control Board official Lone Star Chapter of the Sierra Club

Whole and chipped tire burning may be dangerous due to increased dioxin pollution. Why be concerned over cement kilns and dioxin pollution? Here is a summary of recent scientific concerns stating why Dioxin is a significant public health threat! ¥ Reduction in sperm count by 50% and increased sterility among men in industrialized countries since the 1930's with introduction of chlorinated chemicals (dioxin is unwanted byproduct); ¥ Immune system compromised in wildlife and human populations; ¥ Increases in cancer of the testicles in many industrialized countries; ¥ Increased incidence of undescended testicles in humans and in wildlife; ¥ Increased incidence of hypospadias -- a birth defect of the male genitalia; ¥ Reduced fertility and increased sterility in birds, fish, shellfish, and mammals; ¥ Decreased hatching success in birds, fish and turtles; ¥ Demasculinization and feminization in male fish, birds, and mammals; ¥ Defeminization and masculinization of female fish and birds; ¥ Gross birth deformities in birds, fish and turtles. Permit request to burn tires sent to TNRCC, but no Public Notice or Public Hearing!!! Texas Lehigh sent a permit application to the Texas Natural Resource Conservation Commission (TNRCC), but no Public Hearing will be given to citizens if public notice is not required. Gov. Bush's TNRCC claims no significant change in the nature or volume of emissions (100% coal vs. tire/coal burning). Tire burning creates dozens of toxic byproducts and may be worse than coal! Without public participation in a democratic process, the Bush-run TNRCC will allow inefficient burning of scrap tires as a harmful air pollution practice (compared to 100% coal use), thus subjecting residents to potential adverse health impacts. Why should affected citizens not be allowed to come to TNRCC public meetings to ask questions, be denied public notice, and have their property rights and clean air trampled on by TNRCC officials who donÕt live in the cement plant communities? Thanks to the Bush-run TNRCC! Cement kilns are not designed or built to be incinerators; cement kilns granted higher air pollution rates than commercial incinerators Cement kilns are not designed, built or operated to be tire incinerators since they are built and run differently from solid waste incinerators. Cement kilns are also given big breaks--loopholes--in air pollution standards they must meet compared to commercial incinerators (i.e., hazardous, medical, etc). And Cement kilns are going to be paid to burn whole tires with your TIRE dollars, also paid to retrofit their plants to burn them, and then pollute your air because of bad government policies! Key differences allow cement kilns burning waste/tires to emit higher levels of the following pollutants: ¥ Higher emissions of harmful respirable particles -- PM10 ¥ Higher rates of carbon monoxide -- CO ¥ Higher emissions of nitrogen oxides -- NOx ¥ Higher emissions of sulfur dioxide -- SO2 ¥ Higher volumes of heavy metals -- Pb, As, Cr VI, Hg, Cd, Be, Zn, Se, Th, ¥ Higher concentrations of dioxins, furans and PCBs ¥ Higher amounts of all acid gases such as hydrogen chloride -- HCl ¥ High stack opacity -- more smoke and dust Air pollution problems from tire burning in cement kilns Air pollution is a chief community concern in whole tire burning. Edward W. Kleppinger, PhD, concluded in a scientific paper that tire burning is likely to increase carbon monoxide, particulate, zinc and/or PAH emissions; higher zinc emissions are due to the typically higher content of the metal in tires compared to coal. He recommends that whole tires should not be burned (enclosure E. Kleppinger, Ph.D., ÒTire Burning by Cement Kilns: An Approach to a Policy.Ó) In another paper, Dr. Kleppinger compared tire burning to coal in the cement industry for the Ash Grove Cement Co.'s proposal to burn tires as fuel. Dr. Kleppinger concluded that tire burning increases: ¥ Chromium emissions by almost 500% ¥ Nickel emissions by over 450% ¥ Lead emissions by an astonishing 7 to 91 times ¥ Cadmium emissions by 5 to 10 times ÒPreliminary Evaluation of RMC Lonestar Davenport Cement Plant: Proposal to Conduct Testing on the Use of Whole Rubber Tires as a Supplementary Fuel in the Cement Mfg Process.Ó (May 1, 1992). Study found that burning 30% tires in cement kiln with coal increased toxic emissions over 100% coal. Toxic chemical emissions increased when burning tires together with coal rather than 100% coal included: a) Tetrachlorodibenzofuran (TCDF): 2,230% increase; b) Tetrachlorodibenzodioxin (TCDD): 1,432% increase; c) Total polychlorinated biphenyls (PCBs): 2,608% increase; d) Chromium (hexavalent): 727% increase; e) Lead: 388% increase; f) Naphthalene: 23,938% increase; g) Acenaphthylene: 18,836% increase; h) Phenanthrene: 1,824% increase; i) Anthracene: 2,775% increase; j) Pyrene: 1,089% increase; k) Flouranthrene: 291% increase; l) Total toxic PAH's: 2,190% increase; m) Benzene: 126% increase. This study also concluded that the cancer risk from the cement kiln when burning tires would be approximately 5 in a million. Even so, the RMC report admits that the 5 in a million estimate omits consideration of noninhalation cancer risks from the highly toxic chemicals arsenic, cadmium and PCBs.
