 Gregg Township is a township of the second class, governed by a board of three supervisors.The township has been zoned since 1968, with a three-member hearing board.This was the subject of a zoning battle in the early 1990s when a Texas waste company called USPCI attempted to locate a toxic waste incinerator across Route 15 from the Allenwood Penitentiary, leading to the local community to unite under the banner of the Organizations United for the Environment.
