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 of
NPDESSPDESMS4
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

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 County
The 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 Lake
Identified as a class A water body by the NYSDEC, 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 Further
The 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 Outlook
As 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 SCISWMP 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 Drop
Through 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.
