The Southeastern Pennsylvania Transportation Authority (SEPTA) is a regional public transportation authority that operates bus, rapid transit, commuter rail, light rail, and electric trolleybus services for nearly 4 million people in five counties in and around Philadelphia, Pennsylvania. It also manages projects that maintain, replace and expand its infrastructure, facilities and vehicles. SEPTA is governed by a 15-member board of directors. The City of Philadelphia appoints two members: one member is appointed by the Mayor, the other by the City Council President. These two board members can veto any item that is approved by the full SEPTA board because the city represents more than two-thirds of SEPTA's local subsidy, fare revenue, and ridership. However, the veto may be overridden with the vote of at least 75% of the full board within 30 days. Bucks, Chester, Delaware and Montgomery counties appoint two members each. These members are appointed by the county commissioners in Bucks, Chester, and Montgomery and by the county council in Delaware. The majority and minority leaders of the two houses of the Pennsylvania State Legislature (the Senate and the House of Representatives) appoint one member each, for a total of four members. The governor appoints one member.
