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.

TMDL Alternatives

The National 303(d)/TMDL Webinar Series held a webinar on TMDL Alternatives on Thursday, May 3rd, 2018.

This webinar featured three presentations:

Scott Heidel (PA DEP) presented on The Alternative Restoration Plan for Kishacoquillas Creek charts a path toward restoration of aquatic life and attainment of water quality standards for an agricultural watershed in Central Pennsylvania. A reference watershed approach was applied to develop load reduction goals for nutrients and sediment. Modeling was done using the MapShed model to represent the phased restoration approach to BMP implementation taking place in the watershed and demonstrate progress toward water quality goals at each stage.

Cam Mcnutt (NC DWR) gave a presentation titled “Watershed Action Plan.  Online mapped based tools to build watershed restoration plans.”

NC DWR is developing tools and workflows to efficiently and effectively build Watershed Action Plans that are dynamic and engage a wide range of stakeholders in the restoration planning process. The Watershed Action Plan development process will focus on using resources to implement rather than plan by optimizing opportunities and using non-regulatory mechanisms to restore water quality. DWR will present the various planning tools and demonstrate how these tools integrate across Clean Water Act programs. Most importantly, DWR will demonstrate how all types of restoration projects from best management practices to stormwater control measures to instream habitat restoration can be tracked and accounted for in the Clean Water Act paradigm.

Heather Husband (ND DOH) presented on “North Dakota’s Alternative Plans.” This presentation provided a general overview of why North Dakota chose to do alternative plans and how it fits into their Universe of water quality programs.

Chloride TMDLs

The National 303(d)/TMDL Webinar Series held a webinar on Chloride TMDLs on Thursday, March 1st, 2018.

This webinar featured two presentations:

  • Will Isenberg, Virginia DEQ, presented “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 presented “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 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.

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
