The US Department of Transportation has ordered states to kill their implementation plans related to the National Electric Vehicle Infrastructure program, according to a memo obtained by WIRED that was later made public. The decision appears to halt in its tracks a $5 billion program designed to fund state projects to install electric vehicle charging stations across the United States.

Officials at the Federal Highway Administration (FHWA), which manages the program, ordered state transportation directors to “decertify” the plans that all 50 states have used to outline where and how they will build their charging stations, and with what companies they’ll contract to do so. States have followed those plans to build more than 30 charging stations across the US, with hundreds more on the way.
