"Shortly after helping to elect Gov. Scott Walker (R-WI), Koch Industries opened a new lobbying office in Madison near the state capitol. However, little has been disclosed about the Koch lobbying agenda in Madison. The New York Times reported that Koch political operatives privately pressured Walker to crush public employee unions. But Walker's major payback to Koch relates to environmental deregulation.
ThinkProgress has learned that the Walker administration, along with state Supreme Court judge David Prosser, has quietly worked to allow Koch's many Georgia Pacific paper plants to pollute Wisconsin by pouring thousands of pounds of phosphorus into the water.
Koch's Georgia Pacific plants are well known for releasing large amounts of phosphorus into Wisconsin's waterways. A report by the state government showed that Georgia Pacific is responsible for about 9% of total phosphorus pollution in the Lower Fox River near Green Bay."
