WHAT IS STORMWATER?

• Stormwater is precipitation that does not soak
  into the ground, but runs into a conveyance, such
  as a ditch or culvert
• Stormwater flows from rooftops, roads, driveways,
  gutters, bare soil and all impervious surfaces
• Stormwater picks up soil, salt, fertilizer, oil,
  debris, grease, animal waste, and other
  contaminants before it is discharged into local
  water bodies

3
STORMWATER IN URBAN AREAS

• More impervious surface means more stormwater
  runoff which means increased surface water
  pollution

4
WHATS THE PROBLEM WITH STORMWATER?

• Studies show that industrial or wastewater
  discharges are not the exclusive major surface
  water contamination sources, but that unregulated
  municipal stormwater discharges provide
  significant contamination as well
• Stormwater picks up contaminants and pollutants
  and carries them into nearby water bodies

5
E.P.A. STORMWATER STUDIES

• Clean Water Action Plan (1998) The main causes
  of surface water pollution

6
WHAT DOES STORMWATER POLLUTION LOOK LIKE?

• Debris or chemicals that will eventually be
  washed into the stormwater collection system

7
THE CLEAN WATER ACT

• Enacted in 1972
• Driven largely by the fire on the Cuyahoga River
  in Ohio
• Goal was to maintain and restore the chemical,
  physical and biological integrity of the waters
  of the United States

8
NATIONAL POLLUTION DISCHARGE ELIMINATION SYSTEM
(NPDES)

• Set up by Section 402 of the Clean Water Act
• Regulated discharges from sources such as
  industrial and municipal wastewater (point
  sources)
• Amended in 1987 to include requirements from
  non-point sources such as stormwater
• The regulations were implemented in two phases

9
PHASE I REGULATIONS FOR NPDES

• Took effect in 1990
• Included municipalities with populations greater
  than 100,000
• Included many industrial activities and all
  construction sites disturbing more than five
  acres

10
PHASE II REGULATIONS FOR NPDES

• Took effect on March 10th 2003
• Included municipalities with populations between
  10,000 and 100,000 and population densities over
  1,000 people per square mile
• Added regulation of construction activity
  disturbing between one and five acres

11
DEFINITION OF MS4

• Stands for Municipal Separate Storm Sewer System
• Includes municipalities that have a stormwater
  collection systems that do not mix with municipal
  waste water

12
MS4S UNDER PHASE I II

• New York has approximately 450 separate
  Municipalities that fall under the Phase I or II
  Regulations

13
REQUIREMENTS FOR MS4S UNDER PHASE II

• Apply for a NPDES permit
• Note New York is a NPDES delegated state and
  therefore administers the program. In New York
  it is called SPDES
• Develop a Stormwater Management Plan that
  includes the six minimum control measures that
  reduce stormwater pollution

  actions and specific plans to address each of the
  six minimum measures

  discharges
• Identify where illicit discharges are taking place

18

  plans

19
CONSTRUCTION SITE RUNOFF CONTROL Whats
Involved (contd)

  municipal officials

20
POST-CONSTRUCTION RUNOFF CONTROL Whats
Involved

• Assess existing conditions and determine the best
  way to reduce pollutant discharge to the maximum
  extent practicable
• Regulate post-construction runoff through an
  ordinance enforcement
• Develop a management practice inspection and
  maintenance program

21
POLLUTION PREVENTION AND GOOD HOUSEKEEPING
Whats Involved

• Prevent discharge of pollutants from municipal
  operations
• Follow DEC NPS Management Practices catalog
• Conduct employee training for pollution prevention

22
STORMWATER MANAGEMENT PLAN

• Completed in March 2003 as a requirement under
  the Phase II regulations
• Describes the regulatory requirements applicable
  to Brewster
• Describes the characteristics of Brewster
  including
• The overall population, topography and climate of
  the Village
• The Village role in the NYC watershed
• The existing stormwater conveyance system and
  drainage basins

23
STORMWATER MANAGEMENT PLAN (contd)

• Describes the receiving water characteristics and
  potential pollution sources
• For each one of the six minimum measures it
  outlines proposed control measures and measurable
  goals

PUBLIC OUTREACH AND EDUCATION What Brewster Has
Done

• The Village, through the Village Engineer, has
  compiled a library of stormwater literature
  primarily from the USEPA, NYSDEC, and County
  governments
