"The state has slapped Madison’s sewage treatment plant with 32 air pollution violations alleging excessive emissions from burning biogas and a near absence of effective monitoring and record keeping.

Embarrassed managers at the Nine Springs Wastewater Treatment Plant, who have prided themselves as leaders in environmentally friendly technology, acknowledged that most of the citations are valid and said they are determined to correct them.

“The district recognizes the seriousness of the cited violations and is making every effort to return to compliance,” operations director Paul Nehm said in a letter Tuesday to the state Department of Natural Resources law enforcement bureau."
