The Environmental Protection Agency's request for comments about the issue of lead emissions from aviation fuel acknowledged the difficulties of the avgas transition, saying, “Converting in-use aircraft/engines to operate on unleaded aviation gasoline would be a significant logistical challenge, and in some cases a technical challenge as well.” The agency also acknowledged that a joint EPA-FAA effort will be critical if, as expected, engine modifications will need to be developed and certified. The EPA said, “Given the potentially large number of affected aircraft and the potential complexities involved, a program affecting in-use aircraft engines would need careful consideration by both EPA and FAA and the two agencies would need to work together in considering any potential program affecting the in-use fleet.”
