Question: Which  list of hazardous waste sites in the United States was  Griffiss Air Force Base added to 
Context: New York State Route 825 (NY 825) is a state highway in Oneida County, New York, in the United States.  It extends for 2.59 mi in a generally northwest–southeast direction, connecting the former Griffiss Air Force Base to the Utica–Rome Expressway (NY 49) and downtown Rome.  The highway's southern terminus is at an interchange with NY 49 east of downtown Rome, and its northern terminus is at an intersection with NY 46 just north of downtown.  NY 825 was assigned in 2002 and is ceremoniously named the Griffiss Veterans' Memorial Parkway. Griffiss Air Force Base is a former United States Air Force installation, located in Rome, New York, about 15 miles (24 km) northwest of Utica in central New York state.  Missions at Griffiss AFB included fighter interceptors, electronic research, installation, and support activities, aerial refueling, and bombers. Opened in 1942, the base closed pursuant to BRAC action in 1995 and its airfield is now Griffiss International Airport, owned by Oneida County.  In November 1984 the site was added to the National Priorities List because hazardous chemicals were found in soil and ground water.  Solvents, lead and polychlorinated biphenyls (PCBs) had been disposed in landfills and dry wells A Double cantilever hangar is a type of hangar that was constructed by the United States Air Force during the Cold War.  Large hangers were constructed at Castle Air Force Base, Loring Air Force Base, Carswell Air Force Base, and Travis Air Force Base, while smaller hangars were constructed at March Air Force Base, Edwards Air Force Base, Hanscom Air Force Base, and Homestead Air Force Base. The 24th Air Division is an inactive United States Air Force intermediate echelon command and control organization.  It was last assigned to First Air Force, Tactical Air Command (ADTAC).  It was inactivated on 30 September 1990 at Griffiss Air Force Base, New York. The American Creosote Works Superfund site is an inactive wood-treating facility in Pensacola, Florida located about a quarter-mile north of the confluence of Bayou Chico and Pensacola Bay.  The Superfund program of the United States Environmental Protection Agency (EPA) protects the public and the environment by requiring cleanup of the nation’s worst hazardous waste sites. Chemical waste is a waste that is made from harmful chemicals (mostly produced by large factories).  Chemical waste may fall under regulations such as COSHH in the United Kingdom, or the Clean Water Act and Resource Conservation and Recovery Act in the United States.  In the U.S., the Environmental Protection Agency (EPA) and the Occupational Safety and Health Administration (OSHA), as well as state and local regulations also regulate chemical use and disposal.  Chemical waste may or may not be classed as hazardous waste.  A chemical hazardous waste is a solid, liquid, or gaseous material that displays either a “Hazardous Characteristic” or is specifically “listed” by name as a hazardous waste.  There are four characteristics chemical wastes may have to be considered as hazardous.  These are Ignitability, Corrosivity, Reactivity, and Toxicity.  This type of hazardous waste must be categorized as to its identity, constituents, and hazards so that it may be safely handled and managed.  Chemical waste is a broad term and encompasses many types of materials.  Consult the Material Safety Data Sheet (MSDS), Product Data Sheet or Label for a list of constituents.  These sources should state whether this chemical waste is a waste that needs special disposal. Bowers Landfill, also known as Island Road Landfill, is a former privately owned landfill site covering 12 acres near Circleville, Ohio, on the Scioto River floodplain.  The site operated between 1958 and 1968.  Initially only domestic refuse was accepted, but from 1963 the site began accepting chemical waste from DuPont and PPG Industries.  Waste was either dumped on the ground and covered with a layer of soil, or incinerated in the open air.  Analysis of surface water undertaken by the United States Environmental Protection Agency in 1980 revealed the presence of contaminants and in 1983 the site was added to the National Priorities List (NPL) of hazardous waste sites eligible for long-term remedial action (cleanup) financed under the federal Superfund program.  The cleanup was completed in 1993, and the site was removed from the NPL in 1997, but remains subject to review at 5-year intervals. According to the United States Environmental Protection Agency, mixed waste (MW) is a waste type defined as follows; "MW contains both hazardous waste (as defined by RCRA and its amendments) and radioactive waste (as defined by AEA and its amendments).  It is jointly regulated by NRC or NRC's Agreement States and EPA or EPA's RCRA Authorized States.  The fundamental and most comprehensive statutory definition is found in the Federal Facilities Compliance Act (FFCA) where Section 1004(41) was added to RCRA: "The term 'mixed waste' means waste that contains both hazardous waste and source, special nuclear, or byproduct material subject to the Atomic Energy Act of 1954." Griffiss International Airport (IATA: RME, ICAO: KRME, FAA LID: RME) is a public airport located one mile (2 km) east of the central business district of Rome, a city in Oneida County, New York, United States.  This airport is publicly owned by County of Oneida.  It is located on the former site of Griffiss Air Force Base, which closed in 1995. The National Priorities List (NPL) is the list of hazardous waste sites in the United States eligible for long-term remedial action (cleanup) financed under the federal Superfund program.  Environmental Protection Agency (EPA) regulations outline a formal process for assessing hazardous waste sites and placing them on the NPL.  The NPL is intended primarily to guide EPA in determining which sites warrant further investigation.
Answer: The National Priorities List
