Stormwater Management

What is storm water pollution?
Anything that gets in the path of a raindrop becomes storm water
pollution.  Another name for storm water pollution is non-point source

How is storm water pollution
a problem?

Every time it rains, storm water is carried directly to our surface waters.
That means that storm water pollution can have detrimental effects to
creeks, lakes, ponds, rivers and the oceans into which it drains.

What types of pollutants are
in storm water pollution?

Storm water can carry sediment, trash, automotive fluids like used oil and
antifreeze, grass clippings, leaves, yard waste, excess fertilizers, animal
waste, pesticides and anything else that gets in its way.

What can citizens do to
prevent storm water pollution?

There are several things citizens can do to prevent storm water pollution.

Household Hazardous

  • Never dump anything down a
    storm drain.  All storm drains flow directly to creeks and lakes.

  • Take used oil, paint and
    other household hazardous waste to recycling centers.

  • Check your car for oil or
    other leaks.

Animal Waste

  • Pick up after your pets.
    Dispose of animal waste properly in a trash receptacle or flush it
    down the toilet.

Lawn Care

  • Apply fertilizers and
    pesticides exactly where you want them.  Avoid over spraying them
    onto sidewalks, driveways or streets.

  • Reduce the amount of
    fertilizers you need to apply by testing the soil in your yard first.

Reducing Runoff

  • Adjust sprinklers so that
    you’re not watering the street or sidewalk.

  • Redirect roof gutters to
    lawns, natural areas or rain gardens.

  • Talk you car to a car wash
    instead of washing it on the driveway.

Pool Water

    • Pool water must be dechlorinated before discharging.

    • The federal Clean Water Act prohibits the discharge of pollutants to waters.
      Even seemingly small concentrations of chlorine can harm aquatic life. Chlorine can
      be very toxic to fish, small crustaceans, and plankton. The U.S. Environmental
      Protection Agency acknowledges that at 1mg/L or less chlorine has a high acute
      toxicity to aquatic organisms.

    • It is against federal law to discharge chlorinated water without first reducing chlorine
      to acceptable levels (<0.1 mg/L).


      Consider the following options for removing chlorine:

    • Simply stop adding chlorine to your uncovered pool and wait. Sunlight will help
      to naturally dissipate the chlorine within 10 days. During that time, use
      a swimming pool test kit to measure chlorine.


    • Chemically dechlorinate the pool water. Chemicals that will quickly remove chlorine are available through pool and spa care vendors.



Yard Waste

  • Sweep up yard debris
    instead of washing it away.

  • Bundle yard waste at the
    curb for pickup.

  • Blow leaves and grass
    clippings back into your yard instead of leaving them in the street to
    wash down the storm drain.

  • Use a compost bin to turn
    yard waste into a useful gardening product.


  • Replant bare areas to
    avoid soil erosion.

  • Keep invasive plants from
    growing in your yard.  Remove them before they have a chance t
    grow and spread.

  • Avoid planting exotic
    plants.  Select only plants that are native to this area.


  • Report spills, dumping or
    suspected water pollution to the Village.

  • Clear clogged storm
    drains.  Blocked drains cause drainage problems.

  • Participate in
    community-wide clean up days and other events.

  • Alert neighbors to the
    storm water pollution problem.

Your Septic System

Overflowing septic systems can result in pathogen pollution:

  • Have your septic system inspected at least every 3 years by a professional

  • Your tank pumped as recommended by the inspector (generally every 3 to 5 years).

  • Household chemicals, gasoline, oil, pesticides, antifreeze, paint, etc. should be taken to the Town S.T.O.P collection sites and not flushed. Overflowing septic systems can pollute our waterways.

Geese and other Waterfowl

Droppings from geese and ducks can be a significant source of pathogens that pollute our waterways:

  • Don’t feed geese and ducks, it encourages them to remain and become full-time residents and create a nuisance

  • Feeding them bread and popcorn in unhealthy for the birds

  • Feeding concentrates geese and leads to human/goose conflicts


Is it illegal to pollute the storm drainage system?
It is illegal to discharge, cause to be discharged, directly or
indirectly, or cause any pollutant to enter into the storm drain system
unless permitted by a NYSDEC permit.  Storm water is the only discharge
permitted in the storm water system with exception of incidental non-storm
water flows which do not negatively impact the quality of the receiving
stream including:

  1. Water line flushing, except
    super-chlorinated water line flushing.
  2. Landscape irrigation.
  3. Uncontaminated groundwater
  4. Uncontaminated, pumped groundwater.
  5. Discharge from potable water sources.
  6. Foundation drains.
  1. Air conditioning condensate.
  2. Irrigation water.
  3. Springs.
  4. Lawn watering.
  5. De-chlorinated swimming pool
  6. Street wash water.
  7. Flows from emergency fire and rescue
    operations other than those resulting from negligence on the part of
    the person who owned or controlled the pollutant.
