Nonpoint source runoff modeling A comparison of a
forested watershed and an urban watershed on the South
Carolina Coast - Christopher W. Corbett et al
1997 Journal of Experimental Marine Biology and Ecology
• Simulation results showed a 5.5 X greater
•
•
volume and sediment yield from urban settings
compared to forested settings
Ratio of rain volume to runoff volume was
14.5% higher in urban settings when compared
to forested settings
Impervious Surfaces
Local Examples of
Stormwater Runoff
Urban Sources of Non-Point Source
Stormwater Pollution
• Construction Site Runoff
• Litter and Debris From Roads and Parking
Lots
• Excess Fertilizer and Pesticides
• Eroding Streambanks
• Vehicle Maintenance – Oil and Detergents
• and many more……
Worsening water quality, locally and
regionally, could result in the City of
Oneonta being required to obtain
coverage under the:
State Pollutant Discharge Elimination
System (SPDES) General Permit for
Stormwater Discharges from Municipal
Separate Storm Sewer Systems
(MS4’s). Permit No. GP0-08-002
GP-0-08-002
• 50 + Points of Compliance, many are
required to be met annually
• Development and Implementation of a
Stormwater Pollution Management Plan
(SWMP)
• Six Minimum Control Measures
• Annual Assessment, Recordkeeping,
Reporting & Certification
Timetable
• Notice of Intent must be submitted within
6 months of DEC notification requiring
coverage
• Years 1-3: Development and gradual
implementation of SWMP, Annual Reports
• Year 3+: Full implementation of SWMP

Public Education & Outreach
•
•
•
•
•
Identify pollutants of concern, waterbodies of concern,
geographic areas of concern and targeted audiences
Develop a education and outreach program designed
to describe the impacts of stormwater, pollutants and
their sources, steps that can be taken to reduce
runoff.
Develop, record, assess and modify measurable goals.
Select activities and goals to ensure reduction of the
Pollutant
Reporting (Year 1): list of pollutants of concern and list
outreach activities for targeted audiences
Public Involvement & Participation
• Comply with all state open meeting laws
• Develop and implement a public participation
•
•
•
•
•
•
program that identifies key stake holders.
Describe activities that provide access to those
who want it.
Identify a local point of contact for concerns.
Public presentation of a draft annual report.
Develop, record, assess and modify
measurable goals
Select public activities and measurable goals to
ensure reduction of pollutants.
Report activities and progress
Illicit Discharge Detection &
Elimination (IDDE)
– Any discharge to a municipal system
that is not composed entirely of storm
water. For example,
• Sanitary sewage
• Garage drain effluent
• Waste motor oil
Illicit Discharge Detection &
Elimination (IDDE) - continued
•
•
•
•
•
•
•
•
Develop, implement and enforce a program to detect
and eliminate illicit discharges
Map the location of all outfalls and storm sewersheds
Conduct a survey and map new outfalls
Prohibit by law illicit discharges and enforcement
Detect and address non-stormwater illicit discharges
Develop, record, assess and modify measurable goals
Select appropriate public involvement activities.
Reporting: Descriptions of resources available and
steps taken (above) over 3 year time period

•
Develop and implement a program that is equal to
GP-0-08-001. Stormwater Pollution Prevention Plan
(SWPPP) required for sites that disturb > 1 acre.
SWPPP review and acts on public complaints.
Provide law for enforcement that allows for site
inspection and sanctions and contains requirements
for site operators and control of construction waste
Educates construction site owners/operators, design
engineers, municipal staff and ensures that site
operators are trained
Maintains inventory of construction sites
Develop, record, assess and modify measurable goals
Select BMP’s and measurable goals to ensure
reduction of pollutants.
Report on progress on above steps over 3 Years
Post-Construction Management
• Provides equal protection as GP-0-08-001. SWPPP
•
•
•
•
•
•
required for sites that disturb > 1 acre, law or ordinance
for enforcement
Includes a combination of appropriate structural and
non-structural practices
Describes procedure for SWPPP review by qualified
professionals
Establish and maintain an inventory of post-construction
practices and ensures long term maintenance
Develop, implement and provide resources
Develop, implement and assess measurable goals
Report on progress on above steps over 3 Years
Pollution Prevention & Good
Housekeeping for Municipal
Operations
• Addresses municipal operations that contribute
•
•
•
•
•
pollutants of concern
Assessment of all municipal operations every 3 years.
Determines management procedures that will reduce
and prevent discharge of pollutants
Prioritizes operations, addresses priorities and includes
training.
Develop, record and assess goals and select appropriate
BMP’s
Report on progress on above steps over 3 Years
Pollution Prevention & Good
Housekeeping for Municipal
Operations - continued
• Reporting
– Complete by the end of Year 1
• identify operations, facilities and infrastructure to be included
in program, describe priorities, management practices
(policies and procedures) and identify staff and equipment
available.
– Initiated in Year 2 and complete by the end of Year 3
• describe housekeeping program, training program and
number of employees trained.
– Complete by End of Year 3
• a description of management practices.
SWCD Oneonta Stormwater
Program
• Mapping of stormwater inlets – complete
• Mapping and inspection of outfalls – complete by end of
•
•
•
•
August 09
Stormwater presentation to municipal officials – June 09
Working Group Meetings with appropriate municipal
departments – July through December 09
Public Education and Outreach – September through
