Stormwater Management

Pollutants of Concern

The most effective stormwater management programs are tailored to protect the community's assets while solving its problems and meeting its particular needs. Designing our stormwater management program to fit our specific circumstances required gathering information about existing stormwater problems and potential sources, as well as identifying natural resources, watersheds, and geographic areas that are valuable and potentially vulnerable to impacts from stormwater.

Pollutants of Concern:

Pollutant of Concern


Potential Impacts

Probable Local Sources

Floatables Litter and debris that floats on the surface or is near the surface of waterbodies. Litter in waterbodies may be contaminated with toxic chemicals and bacteria, are unattractive to look at, and can cause death to aquatic animals and birds. Commonly observed floatables may include paper, cigarette butts, plastic containers, wrappers and cans.

Blowing trash from adjoining rights-of-way.

Silt and Sediment Soil/dirt particles that quickly fall to the bottom of waterbodies. Large amounts of silt and sediment, when dislodged and deposited in water bodies, can disrupt ecosystems by interfering with photosynthesis, respiration, growth, reproduction, and oxygen exchange in water bodies.. Storm water runoff that contains sediment can deposit harmful amounts of silt in sensitive areas such as wetlands, streams and lake bottoms harming habitat needed by aquatic insects and plants. Sediment can also transport other pollutants that are attached to it including nutrients, trace metals, and hydrocarbons.

County highway management practices and winter road maintenance.

Oil and Grease Oil and grease includes a variety of petroleum based products and a wide array of hydrocarbon compounds. Oil and grease may be toxic to aquatic life, even in small amounts. Oil and grease in storm drains can generally be traced to restaurants, automotive leaks and spills, or improper disposal of used oil and automotive products into storm drains.

Potential for contaminants from on-site vehicle maintenance or improper disposal of vehicle fluids.

Non-Stormwater Discharges:

The following non-stormwater discharges are typically exempt from the need for SPDES permit coverage. However, the State has determined the following types of discharges to be substantial contributors of pollutants to this particular MS4. As such, the identified discharges are considered illicit and must be addressed by following the illicit discharge minimum control measure ("MCM") requirements.

Even if these non-stormwater discharges are determined not to be substantial contributors of pollutants, the MS4 has elected to address the following types of discharges in their stormwater management program ("SWMP").

None Specified.
Addressing Pollutants of Concern:

In the broadest sense, how the Oneida County DPW will address pollutants of concern and specific areas of concern is accomplished through the Stormwater Management Program Plan as outlined within this website. More specifically, to address these issues it is necessary for the DPW to undertake several critical stormwater management tasks such as, but not limited to: defining goals for stormwater management practices; tailoring bid and construction policies to meet stormwater management goals and objectives; supporting site planning and decision making to accomplish the best methods for managing stormwater in developed or developing areas; providing for employee and contractor education, public participation, and managing public works operations in a way to reduce pollutants in stormwater.

To assist regulated communities in accomplishing all necessary tasks associated with stormwater management, New York State has required MS4s to meet specific components within six Minimum Measures. For each Minimum Measure, the MS4 must set goals and select specific activities that will reduce pollutants of concern to the maximum extent practicable. Specific elements associated with these six Minimum Control Measures are described further in the website under the headings of:
