Why do a TMDL Implementation Plan for Big Otter Watershed?

What is a tmdl

What is a TMDL?

  • Total Maximum Daily Load (TMDL) is a term used to describe the amount of pollution a stream can receive and still meet Water Quality Standards.

    • Identify all sources of pollution contributing to violation of water quality standards.

    • Calculate the amount of pollutants entering the stream from each source.

    • Calculate the reductions in pollutants, by source, needed to attain/maintain water quality standards.

Total maximum daily loads tmdls are mandated by law

Total Maximum Daily Loads (TMDLs) are Mandated by Law

  • Federal 1972 Clean Water Act requires

    • Water Quality Monitoring

    • Periodic Assessment and Impaired Waters Listing

    • Develop TMDLs for Impaired Waters

  • Virginia’s 1997 Water Quality Monitoring

  • Information and Restoration Act (WQMIRA)

  • requires

    • TMDLs for Impaired Waters

    • An Implementation Plan

  • 1999 Consent Degree with EPA to develop

  • TMDL Reports for all 1998 listed streams by

  • 2010

Tmdl 3 part process

TMDL- 3 Part Process:

  • TMDL development

  • Implementation Plan development

  • Implement the plan

Steps after epa approval

Steps after EPA Approval

  • Develop Implementation Plans

  • Continue targeted Best Management Practices

  • Continue stream monitoring: DEQ, Citizen Monitoring

Steps between epa approval and implementation plan start up

Steps between EPA Approval and Implementation Plan Start-up

  • Interim period between TMDL approval and Implementation Plan development

    • Promote implementation of Best Management Practices (BMPs)

    • Initiate educational outreach activities

    • Establish organizational framework for the Implementation Plan development

    • Identify and seek funding opportunities (i.e., grants)

Implementation plan development

Implementation Plan development is required by state legislation (WQMIRA, 1997)

DCR has lead for NPS TMDL implementation plans

DCR, DEQ, and other state, federal and local agencies will support plan development

Implementation Plan Development

Implementation plan development1

Implementation Plan Development

  • Implementation Plan will be done locally

  • Stakeholders will have the opportunity to participate in the plan development

    • Steering Committee, Working Groups

    • Public meetings

  • Guidance Manual for Total Maximum Daily Load Implementation Plans


Integration with other watershed plans

Integration with other Watershed Plans

  • Multiple water quality programs and activities may be underway in individual watersheds

  • Each plan has specific geographical boundaries and goals

  • TMDL implementation will be coordinated with other water quality plans such as:

    • Watershed / Conservation Roundtables

    • Local Comprehensive Plans

Potential funding ource

Potential Funding $ource$

  • Potential funding sources for best management practices (BMPs) selected during Implementation Plan development:

    • USDA Programs - CREP/EQIP

    • WQIA projects

    • Section 319 Funds

    • State Revolving Loan Funds

    • Cost-Share Program

    • Tax Credits

Tmdl 3 part process1

TMDL- 3 Part Process:

  • TMDL development

    • Jason Ericson (DCR) met with the Campbell County Board of Supervisors on December 6, 2004

Why do a tmdl implementation plan ip

Why do a TMDL Implementation Plan(IP)?

  • The implementation plan will open the door to funding that can fund technical assistance and the implementation of Agricultural and Urban BMPs through an implementation project once the plan is completed and approved.

  • The ultimate goal of the Implementation plan is improving water quality through a cooperative partnership in the Big Otter Watershed.

Bacteria load allocation

Bacteria Load Allocation

  • Identify reductions from existing sources to meet water quality standards

  • Consider all sources

    • Direct contributions

      • Permitted point sources

      • Animals in the stream

    • Indirect contributions

      • Septic systems

      • Cropland
