Posted below are EPA's responses (in chronological order) to submitted Part 75 petitions between 2001 and 2017. Note that the actual, signed and dated response sent to the designated representative constitutes EPA’s official response and governs. When a response is posted below, EPA is not aware of any differences between the posted response and the actual, signed and dated response. EPA intends, and believes, that such differences -- if any -- will be minor and nonsubstantive. For more information, or to see petition responses from other years, return to Part 75 Petition Responses.
