Saratoga County Intermunicipal
Storm Water
Management Program
Legislative History
1972- The Federal Water Pollution Control Act a.k.a. The Clean Water Act (CWA)
1987- Amended/Refunded 1990- Phase I compliance begins 1999- Phase II Final Rule is
published(64FR68722) 2003- Phase II compliance begins
Phase I Establishes the National Pollution
Discharge Elimination System (NPDES) A National permit system controlling
“medium” (pop. 100,000-249,999) and “large” (pop. 250k +) urbanized areas (UA)
Est. the base unit of Municipal Separate Storm Sewer System (MS4) to mitigate high level pollution in urban stormflow.
Est. the oversight hierarchy ofNPDESSPDESMS4
Phase II
Regulation of “small” MS4 communities
Small is defined as “…any MS4 not already covered by Phase I NPDES…”
Small construction, disturbing one or more acres, also require a permit
3 Goals
Reduce pollutant discharge to the “maximum extent possible” (MEP)
Protect water quality Satisfy the water quality
requirements of the CWA
6 Objectives
Public Education and Outreach Public Participation and Involvement Illicit Discharge Detection and
Elimination Construction Site Runoff Control Post-Construction Runoff Control Pollution Prevention/Good
Housekeeping

The Moral
Water law flows downhill!
FEDERAL STATE COUNTY MUNICIPALITIES
Phase II requires 6 “minimum control measures” for
regulatory compliance.
Annual reporting to the NYS-DEC, as permitting
agency, is also required by each MS4.
1. Public Education & Outreach
Providing information to the general public of the benefits of a healthy watershed v. the negative impact of polluted storm water runoff.
All available means will be identified and utilized (i.e. Fact sheets, press releases, mailings, the internet,etc.)
Outreach efforts should be made to local leaders, civic groups, at community events, public schools, etc.
2.Public Involvement & Participation
Encourage local citizen participation during the decision-making processes within local community governments so that there is a citizen advisory component to the Saratoga County Intermunicipal Storm Water Management Program
Adequately publicize, in advance, SWMP and local Board meetings relating to SWMP issues encouraging attendance and comments
3. Illicit Discharge Detection & Elimination
Develop a Regional unified systematic approach to map, inventory, categorize and remediate illicit discharges within each MS4
An Illicit Discharge is “…any discharge to an MS4 that is not composed entirely of storm water.”
4. Construction Site Runoff Control
Develop and codify a unified system of local ordinances to control erosion and sediment runoff on all construction sites of 1 acre or more
Develop and distribute a regional hand manual of “Best Management Practices” (BMP) for contractors working in the area
5. Post Construction Runoff Control
Develop and codify a unified system of local ordinances to ensure proper “in situ” runoff controls to promote infiltration of precipitation v. surface flow control
Reduces litter, pesticide/herbicide, and organic wastes entering nearby water bodies
Many control measures are already in common use
6. Pollution Prevention & Good Housekeeping
Programmatic and Personnel development targeted to reduce or, where possible, eliminate pollutant runoff from municipal operations within the Saratoga County Intermunicipal Storm Water Management Program
These objectives are readily achievable through a
conscientious education and outreach effort and a
regional approach instituting a system of accepted BMPs

Saratoga CountyThe fastest growing county in
upstate New York according to the Capital District Regional Planning Commission (CDRPC) and the U.S Census Bureau. County population, overall, grew 30.5% from 1980 to 2000.
Ballston LakeIdentified as a class A water body by the
NYS-DEC, suitable as a drinking water source as well as primary and secondary contact recreation (swimming and boating).
The CDRPC in a combined study of Ballston Lake has identified 6 threats to the future health and viability of the lake.
6 CDRPC Identified Threats
New Development Failing and Outdated Septic Systems Lakeshore and tributary bank Erosion Commercial Activity Agricultural Erosion and Runoff Anti-skid Components
All non-point source pollutants.
The Management Outlook
Planners, Civil Engineers, and Resource Managers alike face common problems as populations and development rise
Increasing populations increase private and commercial development
Increased population and development increase the stresses placed on the quantity and quality of local water supplies
Looking FurtherThe effect then becomes two-fold…A growing population and development
increase potential pollutants and runoff into the existing storm water management system
As projects and homes are completed the increase in impermeable surface area increases the amount of storm water put into the system
…more potential pollutants and increased storm water volumes.
The SWMP OutlookAs populations and development
increase within the SCI-SWMP area the size and frequency of disturbances increases with commercial and residential construction.
New construction increases the total area of impermeable surfaces within the SCI-SWMP area which leads to a growing need to control overland and directed surface runoff
The SCI-SWMP Outlook
The potential synergistic effects of increasing pollution which flowing, untreated, in greater volumes through the MS4 system within the SCI-SWMP is a resource management issue which must be addressed.
The sole purpose of the Phase II SCI-SWMP is to implement a region-wide plan to mitigate these potential problems, now and in the future.
The Value of the SCI-SWMP Locally
With the possible exception of “failing and outdated” septic systems the threats to the Ballston Lake watershed will be partially if not wholly addressed and mitigated by the SCI-SWMP as the program evolves and progresses.
The Last DropThrough a sincere and concerted
effort by the SCI-SWMP, Cornell Cooperative Extension, and the MS4 communities within the program current mandates can be met and long-term regional solutions can be discovered to help ensure the health and viability of our area watersheds.
