Frequent Questions

Will EPA have an oversight testing program for 15 ppm motor vehicle diesel fuel similar to the RFG gasoline survey program?

The RFG survey program is a statistically valid sampling and testing program that is performed by an independent contractor who is paid for by participating refiners. Its purpose is to show whether the RFG in each control area meets standards on average. No such program exists under the highway or nonroad diesel regulations. However, as with other fuels programs, EPA plans to conduct its own sampling and testing at all levels of the distribution system to monitor compliance with the diesel fuel standards.
