Gasoline Standards

Rule Summary

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.

EPA proposed to change the federal volatility (RVP) standard applicable to summer gasoline supplied to the Denver/Boulder area from 7.8 pounds per square inch (psi) to 9.0 psi. This rule was not finalized due to air quality concerns. 

EPA published a direct final rule on January 24, 2002, to relax the federal gasoline volatility standard that applies to gasoline supplied to the Denver/Boulder area from June 1st to September 15th (the ozone control season) of each year. However, we received an adverse comment during the 30 day comment period and are now withdrawing that direct final rule.
