TCEQ toxicologist, Who Has Questioned Ozone Risks, Appointed to EPA Advisory Board


Dr. Michael Honeycutt, director of the Texas Commission on Environmental Quality’s (TCEQ) toxicology division, has been named chairman of the EPA Science Advisory Board.

The U.S. Environmental Protection Agency announced Tuesday it had appointed Michael Honeycutt, the Texas Commission on Environmental Quality’s chief toxicologist, as chairman of the federal agency’s Science Advisory Board.

“I am pleased and honored to bring my knowledge and experience to this prestigious panel,” Honeycutt said in a statement. “It is my goal to direct the other members of the SAB to bring sound science to the reviews that we will make in advising the administrator.”

During his time at TCEQ, Honeycutt courted controversy for leading the fight against an Obama administration push to toughen federal standards on ozone levels, telling the Tribune in a 2014 interview, “I haven’t seen the data that says lowering ozone will produce a health benefit. In fact, I’ve seen data that shows it might have a negative health benefit.”

Under his management, TCEQ scientists concluded that the public health benefit of lowering ozone levels in Texas cities was not worth the cost of added pollution regulations — a conclusion several Texas-based environmental scientists dispute. 

“He’s got a bad history as chief toxicologist,” said Adrian Shelley, executive director of Air Alliance Houston, an environmental nonprofit, in an interview Tuesday. “He’s systematically lowered air quality standards during his time at TCEQ.”
