LeAnn Johnson Koch was quoted in an article in E&E News titled, “EPA Leaders Helped bail Out Failed Philadelphia Refinery,” regarding the bankruptcy of a private equity-owned oil refinery.

"Would it be possible to schedule a call later today or tomorrow to discuss PES' request that EPA use its waiver authority?" LeAnn wrote to the same EPA officials that July.

"Because of timing concerns, the company has begun preparation of the petition, but we would appreciate your feedback in advance," she said in an email that included "RFS Emergency Waiver" in the subject line.

The following month, ahead of another planned meeting with EPA, LeAnn sent along the draft request.

"The petition lays out the company's legal analysis supporting the agency's use of its waiver authority to relieve [PES] of its 2017 RFS volume obligations and contains background information describing the urgent need for relief and the consequences of not securing it," LeAnn wrote. McShane and Gregory Gatta, the former CEO of PES, were included on the email.
