The Beaver is back in southeast Michigan
March 21, 2003
It has been nearly 150 years since the beaver has made its presence known along the Detroit and Rouge Rivers. The hardy little critters were done- in by trappers and toxic water. Lucky for today's beavers, there's no demand for those shiny men's hats that were in fashion in the 1800s.
Michigan to see a "Ducks Unlimited" license plate to support wetlands
March 21, 2013
Wetlands can be a thorn in the side for some developers. They stand in the way of new construction and there are so many rules and regulations for building on or near them. Now environmentalists can request a Duks Unlimited License Plate for $35. $25 will go to restoring wetlands in Michigan.
Ships face reality of lower Great Lakes water levels
March 21, 2013
“Water levels are critical to our industry. Depending on the size of your vessel, you lose anywhere from 50 to 270 tons of cargo for each inch of draft. So at the end of last season, our biggest ships were losing more than 10,000 tons of cargo each trip.”
Regulators: chance of Palisades vessel break resulting in radiation release – one in a million
March 20, 2013
By 2017 the plant’s vessel will become too brittle to legally operate.
In order to keep operating beyond 2017, the company that owns Palisades, Entergy Corporation, is going to have to prove its aging vessel won’t crack in a rare emergency scenario called pressurized thermal shock. At least, the company has to prove the risk of that happening is low enough that it meets NRC rules.
A new life for waste from Michigan's lumbering era
March 19, 2013.
The lumbering boom in Michigan in the 1800s made some people very rich. It also left a lot of waste behind. This article focuses on Muskegon Lake. For those who want more information or to keep up to date on the restoration in Muskegon Lake go to the Muskegon Lake Watershed Partnership website.
Federal regulators to talk about Palisades’ aging nuclear vessel in public meeting online
March 18, 2013
Nuclear regulators will discuss the risk of “pressurized thermal shock,” one of the biggest fears anti-nuclear groups have about the Palisades nuclear power plant during an online meeting Tuesday. Over time the radiation, extreme pressure and heat from the nuclear reactor wear on the metal vessel that contains it. That’s called embrittlement. The more embrittled the vessel, generally the higher the risk of pressurized thermal shock. That's a phenomenon that could happen during an emergency shutdown where cold water (about 40 degrees) would get dumped into the hot vessel (about 550 degrees) and cause it to crack.
Lots of unknowns as petroleum coke piles up along Detroit River
March 15, 2013
Large piles of petroleum coke along the Detroit River have sparked concern from citizens and environmental groups. The “petcoke” is a byproduct of the crude oil refinement process. This petcoke comes from the nearby Marathon oil refinery.
The U.S. Environmental Protection Agency is ordering Enbridge Inc. to do additional dredging in the Kalamazoo River to clean up oil from a massive 2010 spill.
The order, which came down Thurday, requires Enbridge to do the dredging in sections of the river above Ceresco Dam near Battle Creek and in Morrow Lake in Comstock Township.

MDCH releases report on drinking water wells after Kalamazoo River oil spill
March 14 2013
We’re rounding the corner on the three year anniversary of the Enbridge oil spill near Marshall. The cleanup isn’t over yet and so far, more than a million gallons of thick tar sands oil have been cleaned up from the Kalamazoo River and Talmadge Creek. State officials have been looking at possible health risks from the spill. This week, the Michigan Department of Community Health released a report on drinking water wells along the spill zone.
Cited report : Public Health Assessment : Kalamazoo River/Enbridge Spill: Evaluation of crude oil release to Talmadge Creek and Kalamazoo River on residential drinking water wells in nearby communities (Calhoun and Kalamazoo Counties, Michigan). Prepared by the Michigan Department of Community Health, February 27, 2013.
