What you will learn…
• Overview of Bay Water Quality Problems
• Basics of the Bay TMDL
• TMDL implementation
• Critical role of the Counties
![Page 3: Maryland Association of Counties Conference August 12, 2009 Bob Koroncai USEPA Region III The Chesapeake Bay TMDL](https://reader036.vdocument.in/reader036/viewer/2022062519/5697c02b1a28abf838cd843b/html5/thumbnails/3.jpg)
It’s about water quality!
Extensive low to no summer dissolved oxygen conditions
persist throughout the Chesapeake Bay and its Tidal
Tributaries

What is a Total Maximum Daily Load (TMDL)?
• Requirement of the Clean Water Act
• Identifies maximum load to the waterbody to achieve Water Quality Standards– Includes maximum point source loads– Includes maximum NPS loads
In other words... a pollution budget

Myth
• The Bay TMDL will be another paper exercise resulting in limited implementation of nutrient and sediment controls.

Fact
• The Chesapeake Bay TMDL will be unlike any other, being part of a comprehensive framework for implementation.
![Page 7: Maryland Association of Counties Conference August 12, 2009 Bob Koroncai USEPA Region III The Chesapeake Bay TMDL](https://reader036.vdocument.in/reader036/viewer/2022062519/5697c02b1a28abf838cd843b/html5/thumbnails/7.jpg)
Chesapeake Bay TMDL: The Basics
• Will establish a ‘pollution budget’ for N, P, and S
• Will establish load caps for all six Bay states and the District of Columbia
• Planned for completion by December 2010

Who will develop the TMDL?
• EPA Region 3 WPD establishes Bay Watershed TMDLs – Watershed states provide input and support on the
Bay TMDL
– A Stakeholder committee (WQGIT) under the CBP
provides key input
![Page 10: Maryland Association of Counties Conference August 12, 2009 Bob Koroncai USEPA Region III The Chesapeake Bay TMDL](https://reader036.vdocument.in/reader036/viewer/2022062519/5697c02b1a28abf838cd843b/html5/thumbnails/10.jpg)

Plans
June 2010• Draft TMDL
December 2010• Final TMDL Approved
Fall 2009• TMDL public meetings
June – August 2010• Public Comment Period
for Final Draft TMDL (EPA)
• Potential State Meetings on Tributary Strategies

A TMDL is not enough!
BiennialMilestonesfor closing identified program gaps
Identify Gaps between needed controls and existing program
capacity
Effectiveness monitoringto assess implementation actions
Contingencies are employed if effectiveness monitoring indicates that appropriate progress is not being made
ChesapeakeBay TMDL:•Set total nutrient and sediment caps•Wasteload and load allocations•Allocate at finer scales if feasible•Reference other parts of package
DevelopImplementation plansIdentifying the nutrient and sediment controls needed to meet the Basin caps
Evaluate existing capacity (programmatic, funding, technical) to fully implement tributary strategies

So how do we get to a restored bay?
• Need to develop the NPS toolbox of the future• Smarter development• Don’t forget living resources• Meaningful accountability
![Page 14: Maryland Association of Counties Conference August 12, 2009 Bob Koroncai USEPA Region III The Chesapeake Bay TMDL](https://reader036.vdocument.in/reader036/viewer/2022062519/5697c02b1a28abf838cd843b/html5/thumbnails/14.jpg)
County participation is critical!
• TMDL– Local input on allocation, etc, provide local
information• Implementation Planning
– Identify county level loading targets, controls, support needs from state/federal governments
• Implementation– Upgrade WWTP– Work with conservation districts– Adopt ordinances to reduce nutrients and sediment– Smart Growth– Public education
