Refiners granted highest level of biofuel waivers since 2017
The EPA granted 1.76B biofuel credits in exemptions to small refiners, exceeding prior projections. Chevron, Delek, and Marathon Petroleum received exemptions, while refiners without breaks will compensate via reallocation. Shares of Chevron and Delek rose over 2%. The decision balances oil and agriculture interests ahead of elections, with farm-state lawmakers and biofuel producers reacting to the policy.
