target risk levels, the options which will be evaluated for the chemicals to lower their ambient concentrations and the elements of a risk communication plan and process to best inform the community on relevant issues and activities. Sciences International, Inc. conducted a risk assessment of the air monitoring data collected in the study. The final West Louisville Air Toxics Risk Assessment Report, completed in October 2003, details the methods and findings of this assessment. Following the release of the report, the APCD began the process of developing a comprehensive regulatory package to address Louisville's toxic air pollution. In September 2004, the APCD proposed the Strategic Toxic Air Reduction (STAR) Program for public review and comment. The STAR Program was ratified by the Louisville Metro Air Pollution Control Board in June 2005. References Further reading Neighborhoods in Louisville, Kentucky External links Website on Rubbertown
