Ms. Heffernan represents two major interstate pipelines in rate, certificate, and enforcement matters before the FERC and the federal courts. These matters have included filings to construct new facilities and offer new services, filings to recover costs associated with the provision of interstate pipeline transmission service, and various revisions to the pipeline's tariff and pro forma service agreements.
Ms. Heffernan recently represented one of these clients with respect to a non-public investigation by OE. That matter was successfully settled. Ms. Heffernan also recently won an appeal before the D.C. Circuit for these clients related to the FERC's jurisdiction over gathering services.
Ms. Heffernan was recently involved in a successful appellate proceeding for a gas distribution company that concerned the impact of receipts of liquefied natural gas on the facilities of the distribution company. FERC's orders were vacated by the court and, on remand, FERC issued an order addressing our client's safety concerns.
She also represents a major energy company and its natural gas pipeline and electric utility subsidiaries on numerous regulatory and transactional matters before the FERC and the federal courts. Ms. Heffernan also is currently representing an electric utility in a hydro-electric licensing proceeding. The case concerns an existing unlicensed facility and raises complex issues related to the project boundary and dam safety.
