Cough…cough….Yep, bring on more of that clean ethanol!
The castle-like brick building of the old Schmitz Brewery towers over the surrounding houses on the flats of the Mississippi River. For generations, neighbors coexisted peacefully with the smell of beer-making. But in April 2000, the financially troubled brewery — now called the Minnesota Brewing Company — began making a new product: ethanol.
Darren Wolfson, who lives five blocks away, noticed the change in the air immediately. “The second they flipped the switch, it was like a smack in the face, he says.
Emissions from the plant’s 200-foot-tall stack soon began drifting into gardens of the stately homes in St. Paul’s Crocus Hill neighborhood, which overlooks the river flats.
Resident Andy Driscoll says he was flooded with the odor, which he describes “rubbing alcohol mixed with burning corn.”
Prodded by hundreds of complaints, the Minnesota Pollution Control Agency began testing emissions from the plant. They found high levels of carbon monoxide, as well as what are known as Volatile Organic Compounds or VOCs. VOCs included formaldehyde and acetaldehyde, both of which are known to cause cancer in animals.
The vast majority of the nation’s ethanol plants are located in rural countryside outside small towns and cities. There, they have not generated anything like the outcry heard in St. Paul. But given the test results at Gopher State, the EPA began sampling emissions of rural plants as well, and found problems just as severe.
The EPA concluded that “most if not all” ethanol plants are emitting air pollutants at many times the rate allowed by their permits.
Looks like there is a little work to do before I get on that bandwagon. Don’t get me wrong, I don’t plan on hoofing it over to Flint Hills and start snorting from their stacks…But if we are going to put our eggs in this basket, let’s make sure we get it right. They have done wonders with coal!
