BCPH Explores Health Impacts
CEMEX Tire-Burning Proposal, Lyons
Lyons, CO - A second health consultation produced by the
Agency for Toxic Substances
and Disease Registry (ATSDR) is now available.
Two
health consultations
have been produced, at the request of Boulder County Public Health (BCPH), to assess potential
human health impacts of the proposed use of tires as a supplemental fuel
at the Cemex cement plant in Lyons.
The first health consultation, completed in July 2003, analyzed
population exposure from air emissions at the plant. This document is
also available at this web site (1st
Consultation - PDF).
The second health consultation, completed in July 2004, analyzes how
emissions may affect the population through water, soil, and garden
plants. It also answers questions from the community regarding stack gas
sampling issues (2nd Consultation - PDF*).
ATSDR has concluded that the concentrations of the chemicals detected
in the stack gases of the CEMEX cement plant when burning coal, or 19.2%
tires with coal, are unlikely to result in adverse public health effects
in the communities near the plant.
ATSDR, in its July 2004 Report (PDF)*, classified the stack emissions at
this site as "no public health hazard."
*Several errors were discovered in the calculations for NOx,
SOx, and particulates in the tables of the Health Consultation for Cemex,
Incorporated, Lyons, Boulder County, Colorado, dated July 12, 2004. The
corrections made in the tables lower the public’s exposure, therefore the
changes do not affect the ATSDR conclusion that the CEMEX stack emissions
are not a public health hazard and no other revisions of the health
consultation are needed.
