I joined the Creosote Council III in January 2019 as the Technical Advisor. My experiences include working in the field of toxicology for over 30 years where I have designed, executed, reviewed, and summarized toxicology studies ranging from acute mammalian toxicity studies to 2-year oncogenicity studies in laboratory animals. Another unique aspect of my experiences is that I have had the opportunity to oversee acute & chronic aquatic toxicity tests in fish, invertebrates, and plants as well as worked closely with environmental chemists to design environmental fate an effect studies for assessing the environmental risks and hazards for the key wood preservatives. Through my various roles I have interfaced with regulatory authorities on a global basis to submit study reports, discuss toxicity of products of interest, negotiate study designs as well as negotiate testing programs. This is also includes providing full toxicology support to Wood Protection groups for two major Wood Treating Companies spanning the years of 2001 to 2014. In addition, through the American Chemistry Council I carried out the risk assessment on the Occupational Exposures to CCA after the mandated mitigation steps required by the EPA designed to reduce exposures to workers, and the exposure study in workers to demonstrate that the engineering features and improved industrial hygiene practices reduced the exposures and risks to workers from exposures. The Creosote Council III is dedicated to being a responsible steward for the handling and use of creosote in the environment and our research projects are focused on further supporting the continued use of creosote and to the safety of the environment.
