In this case, various environmental groups challenged the state of New York's general permit system which allowed smaller communities to develop stormwater-management programs and limit pollution before seeking approval from the state for the allowable discharge of runoff into rivers and streams. The permit system allowed a general permit to be issued upon the filing of a "notice of intention" to discharge with the Department of Environmental Conservation. The permit system involved a stormwater management plan that included 44 "mandatory best practices" which could be achieved with flexibility. The plaintiffs claimed that such a process did not pressure the communities to reduce pollution to the "maximum extent practicable" as they claimed was required. The court rejected the plaintiffs' argument and wouldn't engage in second-guessing the experience and expertise of the responsible state agencies, and determined it was permissible for the communities to determine for themselves the necessary pollution controls that satisfy federal standards.
