Maryland is home to one nuclear power plant, the Calvert Cliffs Nuclear Power Plant in Calvert County. Another – the Peach Bottom Atomic Power Station – is in southern Pennsylvania, just three miles from the state line. All or parts of the Plume Exposure Zones – a 10 mile radius from the plant – are in Maryland. Additionally, parts of the state are less than 50 miles, or in the Ingestion Pathway Zone, from four other plants: Three Mile Island Nuclear Station and Limerick Generating Station in Pennsylvania, Salem/Hope Creek Generating Stations in New Jersey and North Anna Power Station in Virginia. The Maryland Department of the Environment would be assisted by other state and local agencies in the event of a nuclear power accident affecting Maryland.
