West Louisville Air Toxics Study
Between April 2000 and December 2005, the APCD, the U.S. Environmental Protection Agency, the Kentucky Division for Air Quality, and the University of Louisville worked with the West Jefferson County Community Task Force to conduct an air monitoring study of a substantial number of toxic air pollutants at separate locations in the west Louisville.
Referred to as the West Louisville Air Toxics Study (WLATS), the study was in response to other studies and longstanding resident concerns regarding emissions from Rubbertown, an industrial complex in west Louisville. The goal of the study was to determine if residents of the area were being exposed to toxic air pollutants that may pose unacceptable risks to human health. There were 12 monitoring sites in Study 1 and 6 monitoring sites in Study 2 that were a subset of the first study.
Monitoring took place between April 2000 and April 2001 (Study 1), and November 2001 and December 2005 (Study 2). There were 12 monitoring sites in Study 1 and 6 monitoring sites in Study 2 that were a subset of the first study.
The West Louisville Air Toxics Study Risk Management Plan, Part 1: Process and Framework was issued in April 2003. The Risk Management Plan established the process to identify the sources of the chemicals that were above target risk levels, the options that were to be evaluated to lower their ambient concentrations of those chemicals, and the elements of a risk communication plan and process to best inform the community on relevant issues and activities.
