The Pennsylvania Public Utility Commission (PUC) has 522 employees, including attorneys, rate and service analysts, auditors, economists, engineers, motor transit and railroad specialists, communications specialists, safety inspectors and enforcement investigators. The agency is responsible for oversight of public utilities operating in the Commonwealth of PA. Some of that responsibility includes oversight of natural gas pipelines–like the Mariner East trio of pipelines. So the PUC is an important agency for the Marcellus industry. There are five Commissioners who oversee the agency. One left in March and a replacement was just appointed by the state legislature.
