Strategic Toxic Air Reduction Program

STAR Program: Strategic Toxic Air Reduction

The Strategic Toxic Air Reduction Program (STAR) is a regulatory program to reduce harmful contaminants in the air we breathe, to better protect the health of our citizens, and enhance the quality of life. Since the Air Pollution Control District first implemented STAR in 2005, emissions of toxic chemicals have dropped almost 70 percent in Louisville/Jefferson County.

Why do we need STAR?

The program was created in response to several studies which showed that Louisville had unacceptably high levels of toxic chemicals in the air, particularly in the neighborhoods around a cluster of chemical plants known as Rubbertown. A monitoring study in 2000-01 documented that there were high concentrations of harmful air toxics, including cancer-causing chemicals, in specific neighborhoods. A study by the U.S. Environmental Protection Agency, which included modeling of reported emissions, concluded that our air had the highest potential risk for adverse effects of all of the counties in the eight southeastern states.

The threat to public health from toxic air contaminants was deemed sufficient to warrant action on the part of local government. The STAR Program is our community’s response to these disturbing findings and commitment to improve our air quality.
