INDIANA — The controversial and slow-moving forest management plan inside the Hoosier National Forest hit another roadblock last week. All related activities — including timber sales, prescribed burns, road construction — have been temporarily halted by a court order. The Houston South Project would have opened up about 13,500 acres of the Hoosier National Forest to prescribed burning, 4,000 acres to logging, 2,000 acres to herbicide application and 400 acres to clearcutting. Opponents of the Houston South Project say this ruling is a meaningful step in the right direction.  …Groups like the Indiana Forest Alliance have argued that cutting, spraying and burning on the steep slopes could lead to pollution in the reservoir jeopardizing drinking water quality and public health for the 130,000 people in the Bloomington area. …Chief Judge Tanya Pratt halted the project after finding that the USFS violated the National Environmental Policy Act in failing to consider the potential environmental impacts of the plan.
