Wisconsin lawmakers are hearing today (Tuesday) what people think about relaxing the state’s air pollution rules. The Assembly’s Federalism and Interstate Relations committee has begun a late morning public hearing on a bill from Kewaskum Republican Jesse Kremer, to limit the state’s enforcement to what the federal Clean Air Act requires. Critics say up to 300 types of hazarous air pollutants would go without regulations, but G-O-P lawmakers say that only one third of the pollutants in question are actually emitted. And the D-N-R could still adopt rules that go beyond federal limits — but they would run for only ten years instead of permanently. Business and energy groups have lined up to support the measure, but environmental groups are fighting it.
