Permitted and Reclaimed Mines

icon for permitted mines

icon for reclaimed mines
There are approximately 1,860 permitted mining operations in New York State that mine commodities including sand & gravel, construction aggregate, gem minerals, salt, metal ore and other materials. DEC permitted mines have approved mining and reclamation plans that specify how mining will take place and how the affected land will be returned to a productive use. Since the enactment in 1975 of the Mined Land Reclamation Law, approximately 4,800 mines have received mined land reclamation permits and more than 3,000 mines have been approved as reclaimed by DEC. Most of the reclaimed mines were reclaimed by the permittee/mine operator in accordance with the reclamation plan. Today, sites that were once permitted to mine are used as farms, wetlands, wildlife habitats, residential developments and public recreation areas.

Mine locations have generally been scaled from USGS 7 ½-minute topographic maps provided by the applicant. The location may be either the approximate centroid of the mine or the point where the mine access road enters the public road. This data has not been field-verified but is expected to be within 100 meters (326 feet) of the actual mine, except for older reclaimed mines.
Mine database record for individual site Daily
Oil, Gas and other Regulated Wells

icon for oil and gas well

icon for plugged well
DEC regulates the following well types:
• All oil, gas and solution salt mining wells regardless of depth;
• All wells associated with underground storage of hydrocarbons in caverns or reservoirs; and
• Stratigraphic, geothermal and brine disposal wells greater than 500 feet in depth.
DEC well location information is derived from many sources, including historic maps and paper records that pre-date the existence of a regulatory framework in New York. As such, many locations should be considered "approximate" and are generally expected to be within 100 meters (326 feet) of the coordinates listed. Well locations that have been verified with GPS are expected to be within 15 meters (50 feet) of the coordinates listed. Plugged wells may not have a visible surface expression. The same may be true for some pre-regulatory wells that were abandoned by the operator.

The dataset reflects the status of more than 42,000 wells in the Oil and Gas Wells database as of the previous business day. Wells currently afforded a confidential status in accordance with the ECL are included, but all confidential data is redacted.

Aquatic Biological Monitoring Reports

icon for aquatic biological monitoring reports
DEC's Stream Biomonitoring Unit has conducted biological monitoring (or biomonitoring) since 1972 to assess the water quality of the State's rivers and streams. Biological monitoring provides information on the health of an ecosystem based on which organisms live in a waterbody. The types and numbers of organisms collected from polluted water differ from those collected in clean water, helping DEC determine "how clean" (level of water quality) the water is and to detect water quality changes over time. Fact Sheet Annually
Aquatic Toxicity Monitoring

icon for aquatic toxicity monitoring
As part of the Rotating Integrated Basin Studies (RIBS) program, the Toxicity Testing Unit (TTU) uses various bioassays to look for toxicity in surface waters and aquatic sediments. Tests on ambient surface waters are conducted using the "water flea" Ceriodaphnia dubia (a crustacean), where impacts to survival and reproduction are monitored to identify potential toxic effects. Collected sediments are also analyzed using Microtox®. This toxicity testing system uses the bioluminescent bacterium Vibrio fischeri to screen bottom sediments and porewaters. A reduction in bioluminescence is interpreted as a toxic effect. Toxicity data Annually
