Summary

Oneida County participates in NYSDEC MS4 stormwater program. Construction sites disturbing 1+ acre require SPDES General Permit (GP-0-20-001) with SWPPP. Mohawk River watershed has heightened scrutiny.

These county ordinances apply to unincorporated areas of Oneida County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

New York is rich in surface and groundwater resources. Article 17 titled "Water Pollution Control" of the 6 NYCRR PART 750 Environmental Conservation Law (ECL) was enacted to protect and maintain these valuable resources. Article 17 authorized creation of the State Pollutant Discharge Elimination System (SPDES) program to maintain New York's waters with reasonable standards of purity. The SPDES program is designed to eliminate the pollution of New York waters and to maintain the highest quality of water possible, consistent with: Public health. Public enjoyment of the resource. Protection and propagation of fish and wildlife. Industrial development in the state. New York's SPDES program has been approved by the United States Environmental Protection Agency for the control of surface wastewater and stormwater discharges in accordance with the Clean Water Act; however, the SPDES program is broader in scope than that required by the Clean Water Act as it controls point source discharges to groundwaters as well as surface waters. Determine if you need a permit Regulated Activities New York State law requires a permit for: Constructing or using an outlet or discharge pipe (referred to as a "point source") that discharges wastewater into the surface waters or ground waters of the state. Constructing or operating a disposal system such as a sewage treatment plant. Permits are also required for modifying, transferring, and renewing your permit. No SPDES permit is required for a facility whose treatment system has a design flow of total discharges to ground water of less than 1,000 gallons per day of sewage-wastewater containing no industrial or other non-sewage wastes.

Full Breakdown

Stormwater management in Oneida County is governed by the NYSDEC SPDES General Permit for Stormwater Discharges from Construction Activity (GP-0-20-001, renewed 2020). Any land-disturbing activity of 1 acre or more (or part of a larger plan of development) requires a Notice of Intent (NOI) to NYSDEC and a site-specific Stormwater Pollution Prevention Plan (SWPPP) prepared by a qualified professional. Utica, Rome, Whitesboro, New Hartford, and other urbanized communities are regulated MS4s (Municipal Separate Storm Sewer Systems) and must enforce local stormwater laws. Post-construction stormwater practices must meet the NYS Stormwater Management Design Manual. The Mohawk River and Oneida Lake watersheds receive heightened scrutiny; Sauquoit Creek basin has recurring flooding concerns. Illicit discharge to storm drains is prohibited under each MS4's stormwater local law.

Violations & Fines

NYSDEC can impose fines up to $37,500 per day per violation of the SPDES permit. MS4 local laws typically add fines of $250-$1,000 per offense for illicit discharges, plus restoration costs. Work-stop orders are common for SWPPP violations.
