Since sending a letter to the agency in response to the dramatic increase in UCO imports driving down demand for America crops, Ernst has yet to receive a response from the EPA or any evidence they are regulating UCO entering the United States. The agency has instead shifted responsibility to their federal partners, like U.S. Customs and Border Protection which recently responded to Ernst’s initial letter and made it clear they are not verifying imported UCO as a 100% pure, authentic product that would qualify for the RFS.
