Experience

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.
