Clean Air Not Leading to Diesel Shortages

The Associated Press today reported on diesel shortages in Colorado. The article reports that one of the reasons for the shortage is "difficulties complying with a new federal clean-air rule."

Let's get real here. Complying with clean air rules is not responsible for any diesel shortage. In 2001, the Environmental Protection Agency gave industry until June 1, 2006 to clean up diesel used in highway vehicles, by reducing sulfur content in diesel to 15 parts per million, down from 500 parts per million. That's right--industry has had five years to comply with sulfur reduction requirements and protect our air.

Five years should have been more than enough time to come into compliance, yet industry chose to wait until the 11th hour to plan for clean air. If anything, footdragging, not clean air, is responsible for diesel shortages in Colorado.

Regardless, we can all breathe easier now that clean diesel requirements are finally in effect. The photo below, from the Colorado Power Stroke club website, shows how filthy diesel engines can be and underscores the importance of low sulfur requirements.
