National 303(d)/TMDL Webinar Series

NEIWPCC, through a grant from EPA, is hosting a series of informational national webinars from 2016-2020 on key topics for state, territory, and tribal 303(d) and TMDL programs, as well as other non-governmental stakeholders when appropriate.

The series of informational webinars begins with two webinars in FY 2016, followed by up to four webinars per year in the subsequent years of the grant.

NEIWPCC has coordinated with ACWA’s Watersheds Committee to identify a list of potential webinar topics, and convenes a planning team of state and EPA staff to discuss topics and framework for future webinars to make the series as valuable as possible to our target audiences.

Archives from past webinars are listed below. For additional information about this project, contact Jasper Hobbs.

 Chloride TMDLs

The National 303(d)/TMDL Webinar Series held a webinar on Chloride TMDLs on Thursday, March 1st.

This webinar featured two presentations:

  • Will Isenberg, Virginia DEQ, will present “Accotink Creek Chloride TMDLs and the Salt Management Strategy for Northern Virginia.” This presentation will detail the process for identifying chlorides as a most probable stressor of the benthic community, the evolution of TMDL development assumptions and the role stakeholders played in that, the shifting of focus to implementation, and the current status of the Salt Management Strategy for Northern Virginia that ultimately aims to implement the TMDL.
  • Stephen McCracken will present “Working with chloride TMDLs in North Eastern Illinois.” In 2004 chloride TMDLs were approved for several segments of the DuPage River and Salt Creek systems. Impacted communities responded by reviewing the scale and nature of the problem, identifying potential solutions, and working out how to accommodate large transportation developments in the crowded watersheds.

Examples of TMDL Tracking and Reporting

The National 303(d)/TMDL Webinar Series held a webinar on TMDL Tracking and Reporting on Thursday, September 28th, from 1-3 pm EST.

  • Matt Johnston, of the University of Maryland and the Chesapeake Bay Program Office presented “Making Progress Count: An Overview of the Chesapeake Bay Program’s Efforts to Estimate Pollution Reductions.”
  • Jason Sutter, Arizona DEQ, presented “Tracking Improvements: Arizona’s Water Quality Index.”

Examples of TMDL Implementation

The National 303(d)/TMDL Webinar Series held a webinar on TMDL Implementation on Thursday, June 8th, from 1-3 pm EST.

This webinar featured two presentations focusing on what makes a good implementation plan, implementation with larger projects, and a few case studies.

  • Nicole Sandberg and Ashley Wendt (VA DEQ) presented “TMDL Implementation Planning in Virginia.” As a state required to write implementation plans for their TMDLs, they discussed how to write a good implementation plan, what resources are required, and how to prioritize writing implementation plans.
  • Jayshika Ramrakha (EPA R10) and Bryan Duggan (ODEQ) presented on the “Coquille River Watershed TMDL Mapping Tool,” developed to display shade- and habitat-related geographic information system (GIS) data for the Coquille River Watershed. This tool is intended to be used by stakeholders to query and display layers and support the identification of high value implementation locations. Included in this presentation was a discussion of the Coquille River Watershed’s background and an overview of how this works in the watershed scale.

Coordinating with Agricultural Partners across Clean Water Act Programs

The Environmental Protection Agency Nonpoint Source Program and 303(d) Impaired Water Listing and TMDL Program present the second webinar in this engagement webinar series, “Coordinating with Agricultural Partners across Clean Water Act Programs.” This webinar focuses on intra-agency integration and communication among the 303(d) Impaired Water Listing and TMDL and Nonpoint Source Programs when engaging with the agriculture sector.

This webinar includes these topics:

  • Overview of the National Nonpoint Source Program engagement with the agriculture community
  • Highlight of several case studies of successful interaction between the state Nonpoint Source Program and agriculture community and ways to engage the 303(d) Impaired Water Listing and TMDL Program

Building Consensus for Better Water Quality Outcomes

Drawing on his experience working with multiple stakeholders, Dr. Frank Dukes offers best practices for engaging stakeholders and communities while working on water quality issues. This webinar includes these topics, as well as a very informative Q&A Session:

  • Challenges and rewards of stakeholder engagement
  • How not to build consensus: learning from mistakes—mine and others’
  • Core values of public participation (IAP2) and why they are important
  • A structure for authentic, effective engagement

Frank Dukes worked as a mediator on his first water quality case in 1990. He has served as a consultant, process designer, mediator, and facilitator on many water quality challenges since then, including several TMDL implementation plans.

Modeling Applications to Integrate TMDLs and Permitted MS4s

How can TMDLs be integrated into stormwater planning? How can MS4s numerically demonstrate progress to meeting WLAs? How can regulatory agencies objectively assess the pollution control accomplishments of MS4s? This webinar covered case studies of municipalities in Wisconsin that serve as examples of how to use a dovetailed watershed- and municipal-scale modeling approach to determine pollutant loading and then address implementation needs and considerations. The presentation was tailored to address the variability of MS4s around the country.

The presentation covered the following points:

  • Overview of the types of issues that modeling can address for urban areas with TMDLs
  • Linking TMDL watershed scale modeling to municipal scale modeling
  • How watershed model results can be used to develop detailed implementation plans for several urban communities (using the SLAMM model)
  • Data needs to evaluate permit compliance and inform stormwater management practices

The session was co-presented by the Wisconsin Department of Natural Resources, Brown and Caldwell, and the U.S. Geological Survey. Our presenters each have over 20 years of experience working nationally on watershed and municipal water issues.
