Through the Nutrients Annex of the 2012 Great Lakes Water Quality Agreement, Canada and the United States have committed to:
“… contribute to the achievement of the General and Specific Objectives of this Agreement by coordinating binational actions to manage phosphorus concentrations and loadings, and other nutrients if warranted, in the Waters of the Great Lakes.”
Canada and the United States agree to:
Under this Annex, Canada and the United States adopted Lake Ecosystem Objectives related to algae development for each Great Lake. To accomplish these objectives, the United States and Canada will establish binational phosphorus concentrations, loading targets and allocations while continuing to assess and implement programs and measures designed to manage excess phosphorus from point and non-point sources.
Progress will be made through the implementation of binational strategies and domestic action plans, with consultation and cooperation of partners. Aspects of this annex may be implemented and reported on through the Lakewide Management Annex.
For additional information on the focus of actions under this Annex, consult the current Priorities for Science and Action. The Priorities are based on an evaluation of the State of the Great Lakes, with input from the Great Lakes Executive Committee, participants at the Great Lakes Public Forum, and recommendations of the International Joint Commission.
Every six months, progress on this annex is reported at the Great Lakes Executive Committee meetings. Accomplishments will be described in the Progress Report of the Parties every three years, with the first expected in 2016.
This annex is implemented by a subcommittee co-led by Environment and Climate Change Canada and the United States Environmental Protection Agency. Organizations represented include:
As required, time-limited task teams will be created to focus efforts on a priority issue or project, and will be disbanded when work is complete. Currently, the Nutrients Annex has task groups that focus on:
Task Team | Purpose |
---|---|
Objectives and Targets Development | Starting with Lake Erie, review and update nutrient objectives and targets needed to achieve Lake Ecosystem Objectives. |
Agricultural Sources | Review and evaluate the effectiveness of programs to manage phosphorus runoff to Lake Erie from agriculture. |
Urban and Rural Municipal Sources | Review and evaluate the effectiveness of programs to manage point and non-point sources of phosphorus to Lake Erie from urban and rural communities. |
