Briefing presenters included Bruce Knight (Strategic Conservation Partnerships), Alex Echols (Terra Altus), Brent Fewell (Troutman Sanders, National Water Quality Trading Alliance), Elin Betanzo (Northeast-Midwest Institute), and Victoria Pebbles (Great Lakes Commission). An overview of each of their presentations follows.
- Knight and Echols provided political, policy and technical background on the issue, and addressed the need for innovative solutions to manage nutrients,

- Fewell described the necessary components of and challenges to trading, including trade ratios that require greater projected nutrient reductions from nonpoint pollution sources (i.e., compared to point sources), and the need to account for weather-related and other uncertainties. He also also emphasized the potential pitfalls associated with nutrient trading, and the need to effectively manage liability and credit trading contracts.
- Betanzo described tools for measuring nutrient trading program water quality outcomes, and presented preliminary results from a soon-to-be-released report on water quality monitoring in the Lake Erie Basin. That study indicates that sizable nutrient reduction goals, and five- to ten-year monitoring windows will be necessary to reliably detect water quality changes resulting from nutrient trading or other nutrient reduction strategies.
- Pebbles provided an overview of the mechanics involved in a Fox P Trade pilot trading project in the Green Bay watershed, Wisconsin. That pilot focused on the potential for phosphorus trading between agriculture and point sources, including wastewater treatment plants.
