Reasonably Available Control Technology (RACT) III Hearings

The Reasonably Available Control Technology (RACT) standards were created to satisfy the 2015 National Ambient Air Quality Standards (NAAQS) for ozone. The NAAQS are established by the U.S Environmental Protection Agency (EPA) as the maximum concentrations in the atmosphere for specific air contaminants to protect public health and welfare. The RACT requirements apply statewide to the owner or operator of any major Nitrogen Oxides (NOx) emitting facility, any major Volatile Organic Compounds (VOC) emitting facility or both when the installation/modification of the source(s) occurred on or before August 3, 2018. More details are available here.
