Presentation Transcript

  1. Moores Creek and Lodge Creek, Meadow Creek and Schenks Branch -----------------------------------------------Sediment TMDLs Gene Yagow Virginia Tech Biological Systems Engineering Dept. Second Public Meeting March 15, 2012 Charlottesville, VA

  2. Impaired Segments and Watersheds

  3. Basis for Biological Impairment MooresCreek (MSC) Lodge Creek (XRC) Meadow Creek (MWC) Schenks Branch (SNK) Unnamed Trib (XSN) Biological Metrics Abundance Diversity Pollution tolerance SCI = Stream Condition Index

  4. Basis for Sediment as the Major Stressor

  5. Existing Loads, Reference Loads, and TMDLs

  6. TMDL Components TMDL = ƩWLA + ƩLA + MOS + FG where TMDL = total maximum daily load; WLA = wasteload (permitted) allocations; LA = load (nonpoint) allocations; MOS = margin of safety; and FG = future growth allocation (1%).

  7. MS4 Delineation

  8. Lodge Creek Sediment Loads and TMDL Existing and Reference Sediment Loads The Sediment TMDL (tons/yr)

  9. Moores Creek* Sediment Loads and TMDL Existing and Reference Sediment Loads * Excludes Lodge Creek The Sediment TMDL (tons/yr)

  10. Schenks Branch Sediment Loads and TMDL Existing and Reference Sediment Loads The Sediment TMDL (tons/yr)

  11. Meadow Creek* Sediment Loads and TMDL Existing and Reference Sediment Loads * Excludes Schenks Branch The Sediment TMDL (tons/yr)

  12. Allocation Scenarios

  13. Allocation Scenario • % reductions by landuse are the result of • County wide BMPs used in the Virginia WIP to achieve downstream TMDLs • Additional minor reductions to account for future growth (FG) • Represents a realistic endpoint for sediment loads • Consistent with the Chesapeake Bay TMDL • Expected to allow a return of a healthy biological condition

  14. Lodge Creek Sediment Load Allocation

  15. Moores Creek* Sediment Load Allocation * Excludes Lodge Creek

  16. Shenks BranchSediment Load Allocation

  17. Meadow Creek* Sediment Load Allocation * Excludes Schenks Branch

  18. Next Steps • Setup working groups to transition to Implementation Planning • e.g., Agricultural and MS4 • Receive public comments on the draft TMDL report during the next 30 days • Account for progress already made in the watersheds

  19. TMDL Reduction Goals Agriculture Focus Group Steering Committee IP Analysis and Modeling Growth & Development Focus Group Integration with Local Comprehensive Plans Example Smith Creek Implementation Plan Overview Extents Needed to Meet TMDL Goals Control Measures, Effectiveness, and Unit Costs Implementation Costs Education • Residential Programs • Septic systems • VCE Household Water Quality Program • Pet waste control • VCE Master Naturalist Program • Schools/Youth Programs • Materials for conservation and natural resources management. • Opportunities in Smith Creek watershed for field trips, guest speakers, and community projects • Local Envirothon teams • Expand natural resource conservation and appreciation in Standards of Learning (SOLs) • Developer, Engineer, and Contractor Programs • Make a presentation at a Builders Association quarterly meeting. • Develop a contractor guidance and expectations of sediment control handout. • Encourage single-family home developers to use runoff control measures. • Prepare and distribute periodic stakeholder Erosion & Sediment (E&S) reports. • Distribute “Citizen’s Guide to E&S Control”. • Conduct an LID workshop at a local site that employs LID, e.g. New Market Library or the US Forest Service building in Edinburg. • Municipal Officials Programs • NEMO (Nonpoint Education for Municipal Officials) Program • Utilize DCR, VT, and VCE stormwater specialists • Support development of local stormwater ordinances Goals and Measurable Milestones Stage I Stage II Stage III Smith Creek Implementation Plan Celebration; January 22, 2009; Tenth Legion, Virginia

  20. Ongoing Implementation • Meadow Creek: • entire length natural channel design and restoration (Now – Dec 2012) • Sewer interceptor replacement near completion • Stream Restoration BMP credits being revised • Moores Creek: • 40-ac residential area being treated by constructed wetland (Fall 2012 – Spring 2013) • Ragged Mtn Dam mitigation plan includes a 4-ac wetland (soon) • Coordination with Moores Creek bacteria IP implementation through 319 funding • Coordination with Bay TMDL WIP
