New York Inactive Hazardous Waste Disposal Site Registry: New York's Inactive Hazardous Waste Disposal Site Registry is also known as the State Superfund. According to State authorities, these active or abandoned sites can pose serious environmental or health hazards that require investigation or clean up. Sites include toxic dumps, garbage landfills, factories, dry cleaners or illegal disposal sites that have caused extensive air, water, groundwater or soil contamination.

CERCLIS (Comprehensive Environmental Response, Compensation and Liability Information System): CERCLIS is also known as the Federal Superfund. According to the U. S. Environmental Protection Agency, these active or abandoned sites can pose serious environmental or health hazards that require investigation or clean up. Sites include dumps, garbage landfills, factories, dry cleaners or illegal disposal sites that have caused extensive air, water, groundwater or soil contamination.

NPL (National Priority List): According to the U. S. Environmental Protection Agency, these sites are known to pose serious environmental or health hazards that are top priorities for investigation and clean up. Sites include toxic dumps, garbage landfills, factories or improper waste disposal sites that have caused extensive air, water, groundwater or soil contamination.

New York Hazardous Substance Disposal Site Study: These properties often pose serious environmental or health hazards, but they may have been low priorities for investigation or clean up because on-site contamination may not constitute "hazardous waste." Sites include utility coal tar facilities, wood tar sites and properties polluted with petroleum that have caused extensive air, water, groundwater or soil contamination.

New York Solid Waste Facilities Registry, including New York City 1934 Sites: Solid Waste Facilities include active or abandoned landfills, incinerators, transfer stations, recycling facilities and 1934 New York City garbage disposal sites. These facilities often occupy very large properties and can cause extensive air, water, groundwater or soil contamination that threatens the environment or the public health.

New York State Major Oil Storage Facilities: Major Oil Storage Facilities have at least 400,000 gallons of storage capacity and often experience leaks, spills or other uncontrolled releases that can cause extensive air, water, groundwater or soil contamination that threatens the environment or the public health. Please note that New York has withheld public release of this database since January 2002.

New York and Federal Hazardous Waste Treatment, Storage, or Disposal Facilities:Hazardous waste treatment, storage and disposal facilities hold permits to manage hazardous wastes. They often handle huge waste quantities and occupy very large facilities that experience fires, explosions or other uncontrolled releases of toxic chemicals that can cause extensive air, water, groundwater or soil contamination. As a result, the environment or the public's health can be threatened.

Also includes the following databases:

• RCRA (Resource Conservation and Recovery Act) Violations: According to the U. S. Environmental Protection Agency, regulatory violations have been reported at these sites. These regulatory failures may have caused extensive air, water, groundwater or soil contamination that threatens the environment or the public health.
• RCRA CORRACTS (Corrective Action Activity): According to the U. S. Environmental Protection Agency, corrective action has been undertaken at these sites due to non-compliance with regulatory requirements. These regulatory failures may have caused extensive air, water, groundwater or soil contamination that threatens the environment or the public health.

Toxic Spills - Tank Failures: Tank Failures involve reported structural failures, typically associated with holes or cracks caused by rust or other problems. Uncontrolled releases of gasoline, fuel oil, industrial chemicals or other toxic pollutants often cause extensive air, water, groundwater or soil contamination that threatens the environment or the public health. Gasoline is a major concern because it often contains a toxic additive called MTBE (methyl tertiary butyl ether) that can migrate long distances through soil or groundwater and pollute homes and buildings.

Toxic Spills - Tank Test Failures: Tank Test Failures involve reported tank tightness failures, but the test may have been conducted improperly. Uncontrolled releases of gasoline, fuel oil, industrial chemicals or other toxic pollutants often cause extensive air, water, groundwater or soil contamination that threatens the environment or the public health. Gasoline is a major concern because it often contains a toxic additive called MTBE (methyl tertiary butyl ether) that can migrate long distances through soil or groundwater and pollute homes and buildings.

Toxic Spills: Misc. and unknown causes: stationary and non-stationary source spills where the cause is unknown or includes equipment failure, tank overfill, human error, traffic accidents, abandoned drums, etc.

New York and Local Petroleum Bulk Storage Facilities: sites with more than an 1,100 gallon capacity for storing petroleum products. Please note that New York has withheld public release of this database since January 2002.

New York and Federal Hazardous Waste Generators and Transporters: sites reported by the NYS manifest system and the USEPA's Resource Conservation and Recovery Act Information System (RCRIS).

Also includes the following databases:

• RCRA (Resource Conservation and Recovery Act) Violations: According to the U. S. Environmental Protection Agency, regulatory violations have been reported at these sites. These regulatory failures may have caused extensive air, water, groundwater or soil contamination that threatens the environment or the public health.
• RCRA CORRACTS (Corrective Action Activity): According to the U. S. Environmental Protection Agency, corrective action has been undertaken at these sites due to non-compliance with regulatory requirements. These regulatory failures may have caused extensive air, water, groundwater or soil contamination that threatens the environment or the public health.

New York Chemical Bulk Storage Facilities: Sites storing hazardous substances listed in 6 NYCRR Part 597 in aboveground tanks with capacities of 185 gallons or more and/or underground tanks of any size. Please note that New York has withheld public release of this database since January 2002.

TRI (Toxic Release Inventory Facilities): sites that hold permits to discharge acutely toxic chemicals into air, land, water or treatment facilities and are required to monitor those releases. These sites include manufacturing as well as utility facilities that can cause extensive air, water, groundwater or soil contamination. As a result, the environment or the public health can be threatened.

Historic New York City Utility Sites (1890's to 1940's): power generating stations, manufactured gas plants, gas storage facilities, maintenance yards and other gas and electric utility sites. New York City reports only.

Air Discharge Facilities: facilities that hold permits to release air pollution into the environment and are required to monitor those releases. These discharges can generate extensive air, water, groundwater or soil contamination that threatens the environment or the public health.

PCS Toxic Wastewater Discharges - (Permit Compliance System): permitted toxic wastewater discharges.

Civil and Administrative Enforcement Docket sites: sites that involve cost recovery cases filed by the U. S. Department of Justice on behalf of the Environmental Protection Agency. These cases include site clean up costs as well as fines for violations of regulatory permit requirements that may have caused extensive air, water, groundwater or soil contamination.

Federal Emergency Response Notification System spills (ERNS): a listing of federally reported spills
