4. 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)

5. 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.

6. Clean Water Act of 1972
Goal Prevent the contamination of the surface waters of the state

7. 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

8. 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.

9. Pervious/Impervious Surfaces
Impervious surfaces do not allow water to penetrate into the ground.
Pervious surfaces allow water to penetrate into the ground. (infiltration)

10. 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

11. 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

12. 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

13. 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

14. 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
Host litter clean-up events/watershed clean-up
Partner with other educational events and include MTSU students

15. 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

16. 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

17. Illicit Discharge Examples

18. 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 still has ultimate responsibility with the MS4 program to make sure the permit requirements are met

19. EPSC Certification TBR - MS4 Coordinators need Level I and II training
Level I – Inspecting Erosion Control BMPs - $200
Level II – Reviewing SWPPP documents - $400

20. Construction Site (Silt Fence)
BMPs must be in place per the SWPPP – integral part of construction documents

21. Post (Permanent) Construction
Clean First Flush
Detention Ponds
Water quality vaults
Maintenance Plans – must be maintained and tracked

22. 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

23. 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

24. Examples of Maintenance/Operation

25. Fertilizers and Pesticides
Use good BMPs –
Test Soil for nutrient
overloading
Never fertilize 24hrs.
prior to a storm event

26. Good/Bad Housekeeping

27. 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????

28. 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

29. 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

30. What if we don’t comply?
City of Chattanooga MS4 initially fined - $100, and timeline for bringing program into full compliance – 2005
City of Chattanooga MS4 has been fined again – over $300, – Jan 2011 – If they fail to comply they can be fined up to $1000/day
