EHAP is currently collaborating with the Agency for Toxic Substances and Disease Registry (ATSDR) on a Letter Health Consultation (HC). The HC will use the finalized air monitoring data to evaluate whether long-term air exposures are harmful. If public health risks are identified, the health consultation will provide recommendations to address those risks.

Background Information

AmeriTies-West is an 83-acre wood preserving and railroad tie production facility that has operated in The Dalles since the 1920s. AmeriTies uses the coal-tar byproduct creosote. After receiving complaints about bad smells, the Department of Environmental Quality (DEQ) initiated an odor nuisance investigation of the facility in 2014. In April 2016, an enforceable agreement was signed with AmeriTies to reduce odors, requiring AmeriTies to try alternative solutions. Air quality monitoring was done in 2011 and 2012. In June 2016, DEQ collaborated with OHA to begin a 90-day air quality monitoring plan to measure emissions and collect additional information needed to make a long-term health analysis regarding naphtalene exposures.

Health Education


The document is estimated to be final in late spring 2018.
