Frustrated by lawmakers’ refusal to consider a bill to get tougher on sources of agricultural pollution feeding Lake Erie’s chronic toxic algae problem, Gov. John Kasich on Wednesday took matters into his own hands with an executive order. “This is just requiring farmers to figure out a way to manage their land in a more effective and environmentally friendly way,” the Republican governor said. “I believe that farmers want to do that.”Under the order, his administration will ask the Ohio Soil and Water Conservation Commission at its July 19 meeting to designate eight watersheds or portions of watersheds with high phosphorous levels within the Maumee River Basin as “distressed.” That would trigger the writing of rules affecting all agricultural nutrient sources, including such things as storage, handling, and application of manure; erosion and sediment control from the land; and other agricultural practices. Civil penalties could apply for violations.
