Middle Tennessee State University 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
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 On-site PM Contractor MTSU Stormwater City of Murfreesboro
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
Fertilizers and Pesticides • Use good BMPs – • Test Soil for nutrient • overloading • Never fertilize 24hrs. • prior to a storm event
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
