Water availability, discharge permits, reuse and pollutants: key points for an industrial facility in New York, with official sources.
Reservoirs, rivers and local aquifers can face seasonal shortages even in a state with substantial freshwater resources. New York City's supply, for example, depends on upstate reservoirs. Use dated local drought information and supplier instructions rather than assuming the entire state has one availability level.

DEC generally requires a water-withdrawal permit for a system with capacity of 100,000 US gallons per day or more, subject to specified exemptions. Capacity is based on the combined maximum potential of sources, not simply the facility's typical consumption. A required annual Water Withdrawal Report is due by March 31. Separate rules apply to agricultural withdrawals.
New York's State Pollutant Discharge Elimination System, or SPDES, covers applicable wastewater discharges. Form NY-2C is used for new or modified industrial wastewater discharge permits. The exemption for small domestic groundwater sewage systems below 1,000 gallons per day expressly excludes industrial or other non-sewage waste; it must not be used as a factory wastewater exemption.

The site's SPDES permit or sewer authorization determines the required metal and nutrient controls. Preserve the exact nitrogen or phosphorus forms and sampling periods. Internal recycling must be assessed against these existing conditions and the process's quality needs; it is not covered by a general exemption based only on low discharge volume.
Check combined withdrawal capacity, seasonal supply and the authorized discharge route. Define treatment or retreatment and reuse needs, compare inlet and outlet metals, nutrient forms and process quality, track volumes and reporting dates, and preserve traceable reports with certified authenticity.
Detailed state profiles in this edition: California, Texas, Arizona, Nevada, Colorado, Florida, New York and Michigan. This is a federal overview with eight documented state profiles, not a completed review of all 50 states. For other locations, the federal overview remains useful but a state and local review is still needed. Your discharge permit, sewer authorization and water supply conditions determine the requirements for your facility.
