I drove around with her as we followed trucks laden with liquefied manure and watched as they spread the liquid on nearby farm fields.
It's a practice that can add nutrients back to the land if done right, but with the huge quantities of manure these CAFOs are dealing with year round - doing it right is something they've had trouble with.
And Henning, a "Sierra Club Water Sentinel," has been watching them - reporting them to state officials when they weren't complying with the law.
It's clear from visiting these communities that these large scale farms have caused rifts among neighbors; some like the income they make selling corn and renting land to CAFO operators, but others feel CAFOs threaten their health and the beauty of rural farming life.
Working as an environmental activist in rural Michigan (she formed the group Environmentally Concerned Citizens of South Central Michigan), Henning says she's felt those divisions first-hand - saying she's been harassed and threatened on numerous occasions.
Family farmer and activist Lynn Henning exposed the egregious polluting practices of livestock factory farms in rural Michigan, gaining the attention of the federal EPA and prompting state regulators to issue hundreds of citations for water quality violations.
She's also been to the White House to meet President Obama. And now, here she is on Bill Maher. To watch, we have to pull up a chair up to "imnewshound's" television - he has subscription to HBO, after all (and being HBO and Bill Maher, be warned - there is some foul language):
Large factory farms have lost a major court case in the Michigan Court of Appeals. The case involves farming operations with hundreds, sometimes thousands of animals. They are often called CAFOs, or Concentrated Animal Feeding Operations.
The appellate court upheld a lower court ruling that the state could require large confined animal feeding operations to get pollution discharge permits before opening. Farm groups challenged the state rule insisting they should only need a permit after releasing manure causing water pollution. But today, the three judge panel disagreed:
We conclude that the DEQ was fully authorized to require CAFOs to either (1) seek and obtain an (federal) permit (irrespective of whether they actually discharge pollutants), or (2) satisfactorily demonstrate that they have no potential to discharge. The circuit court properly denied plaintiffs’ motion for summary disposition and granted summary disposition in favor of the DEQ.
Ann Wiowode is the director of the Michigan chapter of the Sierra Club. She welcomes this week’s ruling.
“That is essential in insuring they’re not allowed to begin operation and potentially pollute the water without going through proper review.”
But while she welcomes the decision, Wiowode says more work is needed to protect Michigan from water pollution connected to agriculture.
“We think the regulations are still too weak. And based on our experience, the permits themselves have many things that could be improved.”
