The parties, in cooperation and consultation with state and provincial governments, tribal governments, First Nations, Denis, municipalities, water basin management agencies, other local public bodies and the public are targeting these chemicals of mutual interest to action by recognizing the need to update and strengthen the 1978 agreement to address the current effects on Great Lakes water quality and to anticipate and prevent emerging threats to Great Lakes water quality. The reduction in load for upper lakes is achieved by reaching the concentration of 1 mg/1 of phosphorus (on average monthly) in municipal waste treatment facilities that discharge more than one million gallons per day. The contracting parties also agree to maintain the current oligotrophic state of open water and relative algal biomass in Superior and Huron Lakes. In addition, the United States is committed to making efforts to achieve substantial elimination of algae growth in Lake Michigan. Other measures will be implemented, such as Saginaw Bay, several local problem areas near the coast and Green Bay. (l) to establish special reports to the parties at all times on all issues related to the quality of the Great Lakes; Recognising that the 1978 Great Lakes Water Quality Agreement between Canada and the United States of America, concluded in Ottawa on November 22, 1978, was adopted on October 16, 1983 and November 18, 1987 (the “1978 Convention”) and its predecessor, the Agreement between Canada and the United States of America on Great Lakes Water Quality, reached in Ottawa on April 15, 1972, a key framework for binational consultations and cooperative actions to restore, protect and improve the water quality of the Great Lakes to promote the ecological health of the Great Lakes Basin; (g) regularly consult with the public on issues related to Great Lakes water quality and options for restoring and protecting these waters, while providing the public with the opportunity to raise their concerns, as well as advice and recommendations to the Commission and the contracting parties; Considering that pollutants from air, surface water, groundwater, sediments, flows from non-point-free sources, direct discharges and other sources may be released into Great Lakes waters, (b) if necessary, harmonization of standards, objectives, criteria and guidelines for chemicals of mutual interest; Level 2 non-point source controls include Level 1 plus:Agriculture: use of intensive processes such as: contour ploughing, contour strip cutting, bypasses, tile exit decks, current control structures, vegetation streams, sedimentation ponds and manure deposits. Urban: introduction of practices such as: artificial retention and sedimentation of rainwater and runoff, as well as phosphorus reduction in combined channel overflows. (a) the parties review and receive public advice on the state of the lakes, as well as on scientific priorities and national measures to inform future priorities and actions; and (h) to contact the public to raise public awareness of the intrinsic value of Great Lakes waters, issues related to the quality of these waters, and the usefulness of individual and collective measures to restore and protect these waters; (j) “Waters of the Great Lakes” include the waters of Lakes Superior, Huron, Michigan, Erie and Ontario, as well as the river systems connecting st.
