Summary

Albany County municipalities comply with NY DEC SPDES MS4 permit. New development over 1 acre requires stormwater pollution prevention plan (SWPPP). Green infrastructure encouraged.

City-specific rules exist: Colonie, and Albany have their own stormwater management rules that differ from Albany County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Regulatory Requirements The USEPA and New York State Department of Environmental Conservation (NYSDEC) are increasing their attention in several ways. There are three State Pollutant Discharge Elimination System (SPDES) general permits required for activities associated stormwater discharges. The Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activities (MSGP) addresses stormwater runoff from certain industrial activities. This permit requires facilities to develop stormwater pollution prevention prevention plans (SWPPPs) and report the results of industry-specific monitoring to the NYSDEC on an annual basis. A federal regulation, commonly known as Stormwater Phase II, requires the General Permit for Stormwater Discharges from Municipal Separate Storm Sewer Systems (MS4 GP). MS4 Operators are required to develop a stormwater management program (SWMP) to reduce the discharge of pollutants to the maximum extent practicable. Construction activities disturbing one or more acres of soil must be authorized under the General Permit for Stormwater Discharges from Construction Activities (CGP). Permittees are required to develop a SWPPP to prevent discharges of construction-related pollutants to surface waters. Examples of Pollution in Stormwater Nutrients such as phosphorus and nitrogen can promote the overgrowth of algae, deplete oxygen in the waterway, and be harmful to other aquatic life. Bacteria from animal wastes and illicit connections to sewerage systems can make nearby lakes and bays unsafe for wading, swimming, and the propagation of edible shellfish. Oil and grease from spills during vehicle maintenance activities causes sheen and odor and makes transfer of oxygen difficult for aquatic organisms. Sediment from construction activities clouds waterways and interferes with the habitat of living things that depend upon those waters.

Full Breakdown

Albany County municipalities operate as MS4 (Municipal Separate Storm Sewer System) communities under NYSDEC's SPDES General Permit GP-0-15-003. The City of Albany, Cohoes, Watervliet, and towns of Bethlehem, Colonie, Guilderland, and New Scotland are urbanized MS4s with mandatory public education, illicit discharge detection, construction site runoff control, and post-construction stormwater management programs. Any construction disturbing 1 or more acres requires a SWPPP submitted to DEC under the SPDES Construction General Permit; smaller sites require SWPPPs if in a designated MS4 area. The NYS Stormwater Management Design Manual (2015, updated) governs technical standards emphasizing green infrastructure (bioretention, permeable pavement, rain gardens). The Albany Pool Communities Combined Sewer Overflow (CSO) Long Term Control Plan addresses shared sewer system overflows into the Hudson River.

Violations & Fines

SPDES violations can carry civil penalties up to 37,500 dollars per day per violation at the federal level. Local stop-work orders and restoration are common enforcement.

Frequently Asked Questions

Do I need a SWPPP for my Albany County home build?
Projects disturbing 1 acre or more require a SWPPP under the SPDES construction permit. Smaller lots may still need a basic erosion and sediment control plan.
Who enforces stormwater in Albany?
NYSDEC oversees the SPDES permit system. Each MS4 municipality (Albany, Bethlehem, Colonie, etc.) has a local stormwater management officer for enforcement.
