EPA Administrator Gina McCarthy and Canada’s Environment and Climate Change Minister Catherine McKenna announced that Canada and U.S. have adopted targets to reduce phosphorus entering affected areas of Lake Erie by 40%. Targets will minimize extent of low oxygen "dead zones" in the central basin of Lake Erie; maintain algae growth at level consistent with healthy aquatic ecosystems; and maintain algae biomass at levels that do not produce toxins that pose threat to human or ecosystem health.
