The Michigan Sierra Club brings another complaint to the state about Michigan State University's animal waste procedures.
It's a story we brought you a few weeks ago.
The environmental group first accused MSU of allowing manure to drain into the Grand River, and now the group is upset over some of the university's facilities.
It says some of their animal facilities do not have gutters on the rooftops, and rain water is allowed to run down into animal waste and drain into the water system, but MSU says it's working to fix any problems and takes its responsibility as a research facility very seriously.
The Michigan Department of Environmental Quality is investigating the complaints and says MSU is cooperating.
