Stormwater Program
Shelia Knight, P.E.
Stormwater Program Management
 EPA – Environmental Protection Agency – Federal
Mandate – Clean Water Act 1972
 TDEC – Tennessee Department of Environment and
Conservation – State requires permit
 MTSU/Murfreesboro – Local co-permittees - $3460.00
Permit Types
 National Pollutant and Discharge System (NPDES)
Construction Permits
 Phase II Municipal Separate Storm Sewer System
(MS4)
NPDES Construction
 National Pollutant and Discharge System (NPDES)
Construction Permits
 Operators of construction sites involving clearing and
grading of > 1 acre
 Complete and signed NOI – John Cothern
 Submitted with a Stormwater Pollution and Prevention
Plan (SWPPP) for site to TDEC and City of Murfreesboro
(integral part of construction documents)
NPDES Phase II MS4
 Phase II MS4 Permit - requires regulated small MS4s
in urbanized areas, as well as small MS4s outside the
urbanized areas that are designated by the permitting
authority (TDEC), to obtain NPDES permit coverage
for their stormwater discharges.
Clean Water Act of 1972
 Goal Prevent the contamination of the surface
waters of the state
MS4
 An MS4 is a conveyance or system of conveyances that
is owned by a city or campus designed or used to
collect or convey stormwater
 Polluted stormwater runoff is commonly transported
through Municipal Separate Storm Sewer Systems
(MS4s), from which it is often discharged untreated
into local water bodies
What is Stormwater
 Stormwater is water runoff after a rain storm from
streets, construction sites, parking lots, buildings and
other areas that goes directly into storm drains and
eventually into local streams and rivers.
Pervious/Impervious Surfaces
• Impervious surfaces
do not allow water to
penetrate into the
ground.
• Pervious surfaces
allow water to
penetrate into the
ground. (infiltration)
Stormwater Management Program
 Six Best Management Plans (BMPs) of The Phase II
Permit are:
 Public Education and Outreach
 Public Participation and Involvement
 Illicit Discharge Detection and Elimination
 Construction Site Stormwater Runoff Control
 Post-Construction Stormwater Management for New
Development and Redevelopment
 Pollution Prevention and Good Housekeeping for
Municipal Operations
Timeline for Implementation
 NOC- July 11, 2011
 PIE Plan – 12 months – July 11, 2012
 Illicit Discharge Policy - 18 months – Jan. 11, 2013
 Enforcement and Response Plan – 18 months – Jan. 11, 2013
 Public Participation – 180 days – Jan. 2012
 Stormwater Management Plan (SWMP) – 12 months – July
11, 2012
 Inventory of BMPs – 180 days – Jan. 2012
 Permanent Stormwater Management for Green
Infrastructure – 48 months – City Ordinance
Timeline for Implementation
 SWPPP for Municipal Operations – 12 months to plan
and develop – July 11, 2011
 SWPPP - begin implementation – 12 months – July 11,
2011
 Annual Report and Audits – August 2012
Public Education & Outreach
 Targeted Education with (Public Information and
Education) PIE plan – 12 months to prepare 5 yr. plan
 Partner with WaterWorks, Tennessee Stormwater
Association (TNSA)
 Develop and Distribute media
 Radio/TV broadcast
Public Participation and
Involvement
 EH&S maintain website with important information
about the program
 Update website with public participation
opportunities
 Send complaints to EH&S through website
 www.mtsu.edu/stormwater/
 Host litter clean-up events/watershed clean-up
 Partner with other educational events and include
MTSU students
Illicit Discharges and SPCC
 An illicit discharge is disposal of anything other than
storm water into the storm water drainage system. This
includes illegal connection or tie-ins to the storm
sewer system.
 Sanitary wastewater (sewage overflows)
 Car wash, laundry or industrial wash water - buses
 Concrete truck washout - construction
 Improper disposal of automotive fluids
 Soapy water used to wash parking lots, loading docks
and buildings
 Mop water dumping in storm drain
Illicit Discharge and SPCC
 Annual screening of outfalls – where our system ties to
the City of Murfreesboro or waters of the state
 Update Spill Prevention and Control Countermeasure
(SPCC)Plan
 Regular inspection on campus per the SPCC Plan
Illicit Discharge Examples
Construction Runoff Control
 SWPPP completed by consultant
 Approved by City of Murfreesboro
 Contractor is responsible for twice weekly inspections
 City of Murfreesboro inspects one a month- enforcement
MTSU
Stormwater
City of
Murfreesboro
On-site
PM
Contractor
 MTSU still has ultimate responsibility with the MS4
program to make sure the permit requirements are met
EPSC Certification
 TBR - MS4 Coordinators need Level I and II training
 Level I – Inspecting Erosion Control BMPs - $200
 Level II – Reviewing SWPPP documents - $400
 http://www.tnepsc.org/
Construction Site (Silt Fence)
BMPs must be in place per the SWPPP – integral part of construction documents
Post (Permanent) Construction
 Clean First Flush
 Detention Ponds
 Water quality vaults
 Maintenance Plans –
must be maintained and
tracked
Pollution Prevention and Good
Housekeeping
 Stormwater Pollution and Prevention Plans (SWPPP)
 Employee training – On-line training module
 Employee, Vendors, Contractors and Students must be
educated
Municipal Operations that need Stormwater
Pollution Prevention Plan (SWPPP)
 Building and Vehicle Maintenance Complex
 Clean maintenance area regularly and do not stockpile
loose material near runoff areas/vehicle PM
 Vehicle Fueling and Washing – contain dirty water
 Grounds and Landscaping (ball fields and mowing)
 Tennessee Livestock Center and Miller Coliseum – use
BMPs - cleaning
 Outdoor Storage of Materials – berms
 Street Sweeping – Measureable goals - tons
Examples of
Maintenance/Operation
Fertilizers and Pesticides
Use good BMPs –
• Test Soil for nutrient
overloading
• Never fertilize 24hrs.
prior to a storm event
Good/Bad Housekeeping
Water Facts
 Many cities are paying more for bottled water than
gasoline – 6(20 oz.)bottles= 1 gal.
 70% of earth’s surface is water
 3/10th of 1% of all the world’s water is
usable by humans
 What are you willing to pay????
TMDLs and 303d Listed Streams
 Total Maximum Daily Load (TMDL) for e-coli –
Sinking Creek
 303d listed streams – State listed priority impaired
streams – Sinking Creek – Exceptional Waters of the
State
 Targeted education for pollutants
Enforcement for Non-compliance
 Campus wide program – MTSU must have an
Enforcement and Response Plan – 18 months
 $$$$$$ - Fines for departments
 Progressive discipline – employees
 Stop work orders/cancel contract –
vendors and contractors
 TDEC - Annual Report and Audits
What if we don’t comply?
 City of Chattanooga MS4 initially fined - $100,000.00
and timeline for bringing program into full compliance
– 2005
 City of Chattanooga MS4 has been fined again – over
$300,000.00 – Jan 2011 – If they fail to comply they can
be fined up to $1000/day
