The winter of 1988-89 marked the second program year of the Colorado Oxygenated Fuels Program. As part of that program, the Colorado Department of Health (CDH) conducted a study to determine the environmental and economic impacts of the use of oxygenated fuels. For use in that study, the U.S. EPA contracted for a cost analysis of the program which was conducted by RCG/Hagler Bailly, Inc. The CDH study, with the assistance of the EPA contract study, looked at the air quality benefit and exhaust emission reductions, economic cost, market distribution of available oxygenated fuels, and public education and enforcement activities for the Oxygenated Fuels Program. The findings of this study were previously released in the report, “1988-89 Oxygenated Fuels Program - Air Pollution Control Division Final Report to the Colorado Air Quality Control Commission” (AQCC).
