On April 1, 2020, a policy statement regarding the Washington state department of agriculture (WSDA) delaying enforcement of summer gasoline volatility specifications was signed. As a result of the COVID-19 pandemic and associated precautions, fuel demand has decreased substantially across the nation. Fuel suppliers are currently storing more of the winter blend high volatility gasoline than anticipated. This situation is preventing fuel suppliers from transitioning the supply to summer lower volatility gasoline on the timeline required by the American Society for Testing and Materials (ASTM) standards. Therefore, in order to avoid potential fuel supply disruptions, WSDA will continue to allow winter blend high volatility gasoline to move through the supply chain from April 1 – 30, 2020.

WSDA will continue to allow winter blend high volatility gasoline to be distributed and sold from April 1 - 30, 2020, in order to avoid potential gasoline supply disruptions.

Background: Volatility is the property of a liquid fuel that defines its evaporation characteristics. ASTM International establishes national volatility specifications for fuel and standard testing procedures. The United States Environmental Protection Agency (EPA) establishes volatility control periods that prohibit the sale, supply, dispensing or transport of gasoline whose volatility exceeds standards. The regulations specify the volatility standard by geographical area and time period in which the gasoline is intended to be dispensed to motor vehicles.

On March 27, 2020, EPA, in consultation with the United States Department of Energy, issued a waiver of certain fuel volatility standards to address oversupply issues for winter high volatility fuels (40 C.F.R. Section 80.27). The federal agencies determined that, as a result of the COVID-19 pandemic and associated precautions, fuel demand has decreased substantially across the nation, and suppliers are currently storing more of the winter blend high volatility gasoline than anticipated. This situation could prevent fuel suppliers from being able to turn over the supply to summer lower volatility fuels on the timeline required by the standards and prevent the distribution of an adequate supply of compliant gasoline to consumers.

WSDA's fuel volatility standards, published under chapter 16-662 WAC, currently require a transition to lower volatility gasoline beginning April 1, with another step down scheduled for May 1.

In order to avoid potential fuel supply disruptions, WSDA will continue to allow winter blend high volatility gasoline to be distributed and sold by enforcing the March ASTM D4814 Class E-5/D-4 requirements on gasoline in the distribution system and at retail locations from April 1-30, 2020, under the following conditions:

WSDA will continue to coordinate with the department of ecology and department of commerce's energy emergency management director to ensure that impacts to air quality are minimized and that the transition of the fuel supply is implemented consistent with the needs of the State Comprehensive Emergency Management Plan (ESF-12).


•	The gasoline was produced before April 1, 2020.
•	The gasoline is not blended with butane at the terminal.
