Report from the Clean Air Act Advisory Committee, Clean Diesel Retrofit Work Group, April 2006.

The charge to this work group was to make recommendations to the Agency through the CAAAC process on how to best address the emissions from the legacy diesel fleet with a focus on creating voluntary incentive-based approaches.

This report is the culmination of the work of the Clean Diesel and Retrofit Work Group since April 2004. It provides consensus-based recommendations as well as other recommendations. Some recommendations are sector-specific; others apply more broadly. It is our hope that this report will substantially further our Nation’s efforts to achieve healthy air for its citizens.
