About John Hinckley

I help clients design and operate their facilities to comply with the Clean Air Act. To that end, my goal is to provide clients with high quality information and personal attention to ensure the best possible decisions are made throughout the air permitting process. I direct air emissions permitting and modeling work and have 25 years of experience in a wide range of stationary and mobile air pollution sources throughout the United States. I specialize in air emission estimation, permit application preparation, air emissions dispersion modeling, and pollution control technology assessments. I have presented at local, regional, and national conferences on the topics of air emissions permitting, air emissions modeling, air pollution control, and climate change. I have provided expert witness testimony for state and local review boards and environmental courts.
