DECinfo Locator Map Terms

DECinfo Locator is a map-based way to easily access many documents and public data pertaining to the environmental quality of specific sites in New York State. The prototype will be available soon with limited data sets. By searching an individual location on this map, you can view and download water permits, water quality data, and information about clean-up activities for that location. This tool and data are maintained by the NYS Department of Environmental Conservation.

This prototype focuses on the Newburgh area (Orange County) and the Owasco Lake watershed area (Tompkins and Cayuga counties) only. Additional locations, documents and data will be added in the next version of DECinfo Locator.

Available Functionality

You can access documents and data by clicking on any icon you see on the map. Some icons will only appear when you zoom in closer. There are several additional features you can use within the mapping interface. These are located in the upper right corner of the map.

  • Legend - shows the symbol for each category of facilities and locations we have available data sets/documents.
  • Layers - you can determine which category of facilities and locations you want shown on the map. You can turn each off and on by clicking the check box.
  • Near Me - you can search facilities and locations near you up to a 15 mile radius. You can access documents and data by clicking on the facility name in the category drop down list.
  • Basemap Gallery - you can change the background map view. If you zoom into a particular location, switching to the Imagery with Labels view will show more details, including land boundaries and buildings. The default is set to Streets View.
  • Search - the default setting is to search location names, street addresses and zip codes; if the map doesn't zoom into the location you typed, check that the search dropdown arrow is set to ALL.


The following terms are referenced in the prototype map legend and location description.

Water Quality Monitoring

  • BAP - Biological Assessment Profile: description of stream and river water quality based on biological indicators. More information: biomonitoring web page.
  • Assessment Classifications:
    • Non-Impacted - a BAP more than 7.5 rating; indicates very good water quality. The biological community is diverse, and virtually unaffected by human disturbance. Water quality can sustain fish, shellfish, and wildlife propagation and survival.
    • Slightly Impacted - a BAP between 5.0 and 7.5 rating; indicates good water quality. The biological community is slightly but significantly altered from the pristine state. Water quality can usually sustain fish, shellfish, and wildlife survival, but may be limiting to fish propagation, especially sensitive cold-water fish.
    • Moderately Impacted - a BAP between 2.5 and 5.0 rating; indicates poor water quality. The biological community is altered to a large degree from the pristine state. Water quality often cannot sustain fish, shellfish, and wildlife propagation, but they can usually survive.
    • Severely Impacted - a BAP less than 2.5 rating; indicates very poor water quality. The biological community is limited to a few tolerant species. Water quality cannot sustain fish, shellfish, and wildlife propagation or survival.
    • More information: water quality assessments (PDF).
  • WI/PWL - Waterbody Inventory/Priority Waterbody List: a compilation of water quality information for all individual waterbodies (lakes, rivers, streams, estuaries and coastlines) in the state. Includes PWL ID which is the ID for that segment of a stream/waterbody.
  • More information: Water Quality Assessment Reports web page.

Wastewater Permits

  • SPDES - State Pollution Discharge Elimination System: The federal Clean Water Act prohibits anybody from discharging pollutants into a water of the United States unless they have an SPDES permit. The permit will contain limits on what the permittee can discharge, monitoring and reporting requirements, and other provisions to ensure that the discharge does not hurt water quality or people's health. More information: SPDES web page.
  • WTP - Water Treatment Plant: drinking water facilities that can discharge wastewater from their process of filtering the source water. Also includes Water Treatment Facility (WTF).
  • WWTP - Wastewater Treatment Plant: municipal facilities which collects human sewage and discharges treated water into a large body of water. Operators at these facilities need to be certified and facilities are permitted to prevent waterborne diseases and protect water quality. Also includes Sewage Treatment Plant (STP), Wastewater Treatment Facility (WWTF) and Sewer Districts (SD). More information: Wastewater Treatment Plant Operation web page.

Industrial Stormwater Permits

The Multi-Sector General Permit (MSGP) regulates stormwater discharges associated with industrial activity. The MSGP covers 31 different industrial sectors which include activities such as mining, land transportation, and scrap recycling. More information: MSGP web page.

  • Active - These industrial facilities have activities/materials that are exposed to precipitation so they are required to have MSGP coverage.
  • No Exposure - These facilities are conducting industrial activity that would normally require MSGP coverage, however they are claiming a No Exposure Conditional Exclusion from MSGP coverage because their industrial activities/materials are not exposed to precipitation.

Permitted Farms

  • CAFO - Concentrated Animal Feeding Operation: This is an animal feeding operation (farm) that meets certain animal size thresholds and that also confines animals for 45 days or more in any 12-month period in an area that does not produce vegetation. New York State has more than 500 CAFOs, the majority of which are dairy farms with 300 or more cows and associated livestock operations. More information: CAFO web page.

Remediation Sites

  • MGP - Manufactured Gas Plant: an industrial facility at which gas was produced from coal, oil and other feedstocks. This process created wastes which may still remain at MGP sites already closed, potentially impacting surface and groundwater.
  • ROD - Record of Decision: a document which presents the remedial action plan for an inactive hazardous waste disposal site and details the information and rationale used to arrive at the decision.
  • ERP - Environmental Restoration Program: reimburses municipalities 90% of funds they spend for cleaning up municipally-owned properties that may be contaminated with hazardous substances or petroleum.
  • Easement - a document which title owners of a property grant to DEC restricting the use of a property to specified categories (e.g., commercial, industrial) or to require the site management of engineering controls (e.g., a landfill cover system) to protect public health and the environment.
  • Registry - a listing of inactive hazardous waste disposal sites DEC has identified. This listing is required by state law and includes basic location and owner information, as well as descriptions of site history, physical aspects, health issues and legal status.
  • State Superfund Program - Enforcement program to identify and characterize suspected, contaminated sites which may pose a significant threat to public health or the environment. These sites go through a process of investigation, evaluation, cleanup, and monitoring.
  • Brownfield Site - any real property where a contaminant is present at levels exceeding the use-based soil cleanup objectives or other health-based or environmental standards, criteria or guidance adopted by DEC. Concentrations of contaminants at these sites limit redevelopment and productive use.
  • More information: Environmental Cleanup & Brownfields web page.

Chemical Bulk Storage (CBS)

These are facilities that store hazardous raw materials in large tanks. All regulated tanks at facilities must be registered with DEC and managed in compliance with applicable regulations. More information: Bulk Storage web page.

Petroleum Bulk Storage (PBS)

These are facilities that store more than 1,100 gallons of petroleum products in aboveground or underground storage tanks. All regulated tanks at facilities must be registered with DEC and managed in compliance with applicable regulations. More information: Bulk Storage web page.

Major Oil Storage Facility (MOSF)

These are large facilities that store a total of 400,000 gallons or more of petroleum products in aboveground and underground storage tanks. Facilities must be licensed by DEC and managed in compliance with applicable regulations. Vessels that transfer petroleum to another vessel while operating in the waters of NYS must also be licensed. More information: Bulk Storage web page.
