Grassley has had enough of EPA administrator if he doesn’t stop granting RIN waivers

In Washington, Reuters reports that Senator Chuck Grassley has taken to Twitter to tell the Environmental Protection Agency’s administrator to clean up his act on hardship waivers under the Renewable Fuels Standard or to start looking for another job. The senator has held back from supporting calls for the administrator’s resignation despite pressure from other Congressmen but now believes that enough is enough. His tweet drew fire from supporters of smaller refiners saying that the EPA is just holding up the law.
