Algae blooms on Lake Champlain.
Last month, the Environmental Protection Agency rejected Vermont's plan to reduce phosphorous pollution in Lake Champlain. The EPA had approved the plan back in 2002, but now says it does not meet federal requirements. That decision came in response to a 2008 lawsuit filed against the Agency by the Conservation Law Foundation, which says that the limits Vermont's plan set on phosphorous pollution were not tough enough and that the plan did not take into account the impact of climate change. Now, the EPA is working with the state to reassess conditions in the lake and put together a new cleanup plan.
