You’ve got something special, contact the DNR

By Steve Veysey, Ames

I don’t live in Winneshiek County, but I’ve been fishing there since 1993 when I first took my 4 and 6-year-old sons to the Highlandville campground to catch trout in North and South Bear Creeks. You have something special. Novilla RNG has persuaded two western Winneshiek County dairies to partner in a manure digester project. The scuttlebutt is that Novilla will make their money based upon how much methane they put into a pipeline. What you may not know is that the project will receive federal tax credits that may be worth up to 10 times the actual value of the methane. And those tax credit certificates are fungible – bought and sold on the open market. That’s why this is all happening, and in such a hurry.

Most likely, the dairies will be compensated based upon how much manure they provide as feedstock to the digesters. One can imagine that those contracts require a minimum amount of manure be provided, and the more manure, the more money to the dairy. It’s no surprise that both dairies have expressed plans to expand. After passing through the methane digesters, about 94 percent of the processed manure will still have to be land-applied on nearby fields – just like it is now. But the digested manure will have larger concentrations of nitrogen and phosphorus, and those nutrients will be in more plant-available forms. In theory that means that more field acres should be required in the manure plans to agronomically accept the nutrients. But the DNR seems poised to approve a manure plan based upon the old nutrient levels and nutrient availability values. This could lead to over application and increased risk to both ground and surface waters.

Then there is the issue of the DNR water use permits both dairies recently applied for to support expansion. Combined, they are requesting 150 million gallons per year, much of it from the deep Jordan aquifer. That’s 132 million gallons per year more than they are allowed to use now. It’s more water than the use of Ridgeway and Cresco combined! Water from the Jordan is the cleanest you have, and it may take centuries to replenish once it’s gone. If you live in the Winneshiek townships of Lincoln, Orleans, Bluffton, Madison or the Howard townships of Vernon Springs or New Oregon, you might want to express your concern. Email your story to wateruse@dnr.iowa.gov. Ask the DNR to deny the 130 MGY water use increase.
