Southwest Lake Michigan Pilot Study

The Southwest Lake Michigan Pilot Study Final Report

Developing an Inventory of Toxic Air Emissions from Area Sources in the Chicago, Milwaukee and Gary Urban Areas, 1993

The SWLM Pilot Study Final Report, released in December 1995, contains the first multistate inventory of toxic air emissions compiled in the United States. It documents a 12-county study of small point and area sources of 49 toxic compounds, using 1993 calendar year data compiled by the air divisions of three states: Illinois, Indiana and Wisconsin. This effort represents a unique milestone in the continuing effort to quantify and manage the toxic air emissions that impact the water of the Great Lakes Basin. The report also documents development of the inventory software, the Regional Air Pollutant Inventory Development System, and quality control/quality assurance measures undertaken in t he effort.
