Mysterious My Ash: This Black Stuff Coats Homes and Lungs


Update: Oct. 13, 2010: DNRE responds to concerns from citizens (and Mr. Great Lakes). Gasps heard throughout Bangor Township. Likely “city mold.” Particulates still coming from plant. Sigh.

Oct. 12, 2010:

So there’s a story in today’s Bay City Times. It’s about this “mysterious” black stuff that people in Bangor Township (where Mr. Great Lakes lives) say has been coating homes for the past few months. Some residents are quick to point their finger at the Consumers Energy Karn-Weadock complex in Bay County’s Hampton Township. That’s the right direction, based on the wind. But let me tell you what really blows.

Karn-Weadock piles its coal ash along Saginaw Bay, and some dust is inevitably carried away by the wind. But what’s worse than that is the stuff that billows from the stacks there and is carried away by the wind. Out of sight, out of mind, right? Well, you’re inhaling that stuff if you live in the vicinity of this plant’s exhaust.

“Oh, Mr. Great Lakes,” you may say, “you have no proof of this.”

Really? From the story:

Consumers Energy does contract a boat cleaning service at the Bay City Yacht Club, 3315 Shady Shores Road in Bangor Township, to clean boats that are sometimes dirtied by particulates from Karn-Weadock Generating Complex. The Bay City Yacht Club is situated approximately 1,000 feet northwest of the plant’s coal piles.

The Bay Road neighborhood is within a mile northwest of the Bay City Yacht Club, which puts it on the same trajectory that strong northwest winds sometimes carry coal particulates from the Consumers Energy plant.

Another word for coal particulates is particulate matter. That’s soot so small that it’s inhaled deep into your lungs, where it shortens your life. That’s not my opinion. That’s a fact. Consumers has acknowledged those particulate deposits by paying a boat cleaning service to wipe away the soot.

So what is the company going to do about the mysterious black stuff?

Consumers Energy Spokesperson Mary Gust said the company is unaware of any problems in that area.

“We’re not aware of any complaints from that area,” she said. “If we do receive an inquiry, we do investigate. Typically what we’ll do, we’ll visit the site and collect samples. We find, oftentimes, that results indicate it’s biological in nature.”

Clearly, Consumers hasn’t been paying attention to environmental groups like Lone Tree Council who have for YEARS lodged complaints and concerns about particulate matter levels from the plant. Sure, the plant may meet the federal limits for particulate pollution. Give them a medal, please. Levels of particulates at current standards have been linked to diabetes.

But let’s give Consumers a chance here. The spokeswoman says her company typically visits sites to collect samples if they receive an inquiry. Let’s hope complaints from several residents and a story in the newspaper qualifies as an “inquiry.”

The most mysterious thing about this issue is the lack of a response from the state Department of Natural Resources and Environment, which has an office in Bay City.

Let’s see if the state agency that regulates the coal plant will react. Just don’t hold your breath.

  1. It’s sooty mold. Insect infestations, particularly aphids in the trees excrete a by product called honeydew. Sooty mold, especially in hot, humid conditions that we had this summer in Michigan, love and thrive in these conditions.

    Not that I like coal plants, but I wish you would fact check more before you post anything, as usual.

  2. Hi Kathy. Thanks for your comment. Sorry if my sarcasm was a little unclear. I was saying that besides this latest complaint, there have been problems in the past with particulate matter from the plant, and for Consumers to play dumb is insulting to the people of Bay County. Also, the DEQ and/or Consumers should bother to test this stuff, if in fact they think/know it doesn’t originate from the plant.
