The New York State Pollutant Discharge Elimination System (SPDES) has been approved by the United States Environmental Protection Agency for the control of wastewater and stormwater discharges in accordance with the Clean Water Act. Under New York State law the program is broader in scope than that required by the Clean Water Act in that it controls point source discharges to groundwaters as well as surface waters. Each municipal wastewater treatment plant (WWTP) must operate under an individual SPDES permit that defines the parameters under which it is allowed to discharge to the waters of New York State. The SPDES database contains the following data on each permit: ownership, effective dates, locations, and receiving waters. Data is routinely updated based on the data collection methodology, and this dataset will be updated monthly. Additional information regarding NYS DEC’s SPDES Program, including online data in various formats, is available athttp://www.dec.ny.gov/permits/6054.html.

This dataset is comprised of the final assessment rolls submitted to the New York State Department of Taxation and Finance – Office of Real Property Tax Services by 996 local governments. Together, the assessment rolls provide the details of the more than 4.7 million parcels in New York State.

The dataset includes assessment rolls for all cities and towns, except New York City. (For New York City assessment roll data, see NYC Open Data [https://opendata.cityofnewyork.us])

For each property, the dataset includes assessed value, full market value, property size, owners, exemption information, and other fields.

Tip: For a unique identifier for every property in New York State, combine the SWIS code and print key fields.

The dataset displays the final maximum savings for STAR credit and STAR exemption benefits, from 2019 and forward, as well as a comparison between the two for each year. Through analysis of the data, homeowners can see the benefits of taking advantage of the STAR Credit.

Homeowners can switch from an exemption to a credit through the New York State Department of Taxation and Finance website. [https://www.tax.ny.gov/pit/property/star/]
