B National Pollutant DischargeNPDES PHASE II
STORM WATER
PROGRAM
Lori Haak
City of Chanhassen
BACKGROUND
I
· 1970s: Identified storm water quality as a
major problem in some areas
· 1980s: NURP (National Urban Runoff Program)
and other studies developed to address problem
· 199Ds: NPDES Phase I storm water program · Developed by EPA
· Monitor and guide storm water management
What is NPDES?
· National
· Pollutant
· Discharge
· Elimination
· System
NPDES Phase I Program
· Required that municipalities with
populations over 100,000 create storm
water programs for water quality
· In Minnesota, Phase I applied only to
Minneapolis and St. Paul
and...
NPDES Phase [ Program
· Required industries such as landfills,
airports, vehicle maintenance, mining and
manufacturing to develop storm water
management plans for their sites
and...
NPDES Phase I Program
~ u I I
· Required that all construction sites over .5
acres develop temporary and permanent
erosion control plans and implement best
management practices ("BMPs") to control
erosion
What Will Phase TI Require?
· In addition to the Phase ! requirements:
· IVlunicipal Separate Storm Sewer Systems ("MS4s'3 in
urban areas with populations over 10,000 and under
100,000 will be required to obtain a NPDES permit
· About 180 MS4s in Minnesota
· Population will be based on 2000 census data
· Communities under 10,000 may be added if:
· Discharge to sensitive waters
· Water quality does not meet water quality standards
· Areas of expected high growth
· Located near an urban area
and...
What Will Phase II Require?
· Permits required for construction sites
disturbing over 1 acre
· Can be smaller if project is in a sensitive area
or is considered a sensitive site
· Sites without discharge can be exempted
· Industrial facilities that have no exposure
of activities or materials to storm water
will not be required to obtain a NPDES
industrial permit.
What Will The Local Program
Need To Cover?

Minimum Control Measures ("MCMs")
Construction site storm water runoff control
Post-construction storm water management
Illicit discharge detection and elimination
Public education and outreach
Public involvement and participation
"Good housekeeping" for municipal
operations
What Will The Local Program
Need To Cover?
Fur each M£M:
[] Establish measurable goads
[] Identify the BP1Ps required to meet these
goals
[] Identify measures to track their
performance and progress
Minimum Control Measures
I. Construct/on Ekes
GOAL: TO REDUCE SEDIMENT DISCHARGE
FROM CONSTRUCTION SITES
L Construct/on S/te Requ/rements
[] Contractors must secure permits from
MPCA for projects one acre or larger
[] Municipalities must develop ordinance
controls
[] Municipalities must develop program for
plan review, site inspection and dealing
with complaints and non-compliance
Minimum Control IVleasures
II. Post-Construct/on ManageFnent
GOAL: TO REDUCE THE AMOUNT OF
POLLUTANTS AND THE PHYSICAL
IMPA CT OF NEW DEVELOPMENT
II. Post-Construction BMPs
STRUCTURAL
· Ponds
· Wetlands
· Infiltration
· Filtering Devices
· Vegetated Channels
· Detention
· Special Devices
NON STRUCTURAL
· Advanced Site Design
· Economic Incentives
· Educational Programs
· Recovery Programs
· Fertilizer and Pesticide
Control Programs
· Litter Control Programs
Minimum Control Measures
III. Illicit Discharge
GOAL: TO ELIMINATE OILS, TOXINS AND
OTHER POLLUTANTS FROM OUR
STORM WATER SYSTEMS
III, I/#c/t Discharge BMP$
[] Outfall and system mapping
· Identify "hot spots"
[] Ordinance and enforcement program
[] Detection and elimination plan
[] Dumping control program
[] Educational programs for local workers
and the public
IVlinimum Control Measures
IK Public Education and Outreach
GOAL: TO BUILD COMMUNITY SUPPORT
AND IMPROVE COMPLIANCE
IV. Public Education and Outreach BMPs
[] Brochures and fact sheets
[] Library of educational materials
[] Educational booths and programs
[] Storm drain stenciling
[] Storm water "hotlines"
[] Event participation
[] Watershed clean-up days
Minimum Control Measures
V. Public Involvement and Part/c/pat/on
GOAl: TO BROADEN SUPPORT, REDUCE
OBSTACLES, GAIN EXPERTISE AND
BUILD CONNECTIONS
V. Pub//c Invo/vement BMPs
· Public meetings
· Citizen panels
· Environmental events
· Citizen watch groups
· "Adopt a Storm Drain" programs
Minimum Control Measures
VI. Good Housekeep/ng for IYun/c/pa/ Operat/ons
GOAL: TO REDUCE THE IMPACT OF POOR
OPERA TIONS, PRACTICES AND
DESIGNS
VL Mun/c/pa/ Opera~ions BMPs
[] Develop program to reduce pollution
· Maintenance operations
· Street and highway pollution
· Floatables
· Waste disposal
· Salt and sand: Use and storage
[] Employee training programs
Does Each MSq Have To
Fend For Itself?.
[] No, Poo/ing resources/s okay,
· Smaller communities can be included in larger
NISq permits
· Programs can be offered by others
· Programs can be shared
· State and regional programs can be
recognized
· League of Minnesota Cities Guide Plan
Communities Included:
IL ~ r~ su L~ f~ SL ~ S~ ~ ~

What Is The Timeline?
· December 6, :1999: Regulations published in
Congressional Record
· December 2002: Deadline for issuance of
General Permits for MS4s and construction
activity
· March 2003: All communities must obtain
permit coverage
· March 2003 through March 2008: Plan
implementation
How Will This Work?
· MPCA will establish requirements for each
of the six minimum control measures and
a set of BMP "menus"
· Municipalities will develop a Notice of
Intent ("NOI'9
NO]: Requirements
· Develop a Storm Water Pollution
Prevention Program ("SWPPP'~) to manage
storm water quality and quantity
· ]:dentify BMPs to be implemented
· Develop measurable goals for each BMP
· Develop schedule or frequency for all BHPs
· Assign responsibility for each of the
programs/BMPs
Storm Water Pollution
Prevention Program
GOAL: REDUCE THE DISCHARGE OF
POI £UTANTS TO THE MAXIMUM
EXTENT PRACTICABLE ("PIEP'~
Storm Water Pollution
Prevention Program
· Must address parts of system under
the MS4's operational control
· Application Deadline: March 10, 2003
· Permits in effect through March 2008
· Must retain application and data for at
least 3 years after permit expiration
Then what?
_
· Minnesota Pollution Control Agency
(MPCA) will review and issue permit
· Program implementation within 5 years
(by 2008)
· Annual progress reports by March 10
· Annual public meeting before the
annual report is submitted to MPCA
Keep In Mind...
· The permit is not "one size fits all."
· There is great flexibility in the program.
· There is plenty of room for innovation.
and...
Keep In Mind...
· Permits will affect several City
departments.
· City will experience increased demands
on resources as NO[ is drafted and
permit is implemented.
· Phase II can be both a challenge and
an opportunity.
