West Michigan Park is a popular kids spot in the summer months. Nestled along the Tittabawassee River in Saginaw Twp, the park continues to be indundaed by the dioxin contaminated flood waters courtesy of Dow Chemical.
Will be posting additional pictures this weekend. We are into the 12th year of this contamination. Additional pictures are also available at www.trwnews.net.
Yesterday after decades of delays MDEQ agreed (EPA has been silent) with Dow Chemical and settled on 250 ppt for dioxin in Midland soils. This web site is dedicated to EPA activities along the river system but we cannot ignore the major deviation from the state’s standard of 90 ppt being used in Midland.
Lone Tree Council acknowledges the progress–hell, even talking about remediation in Midland has been taboo for decades. Concerns and comments were submitted to MDEQ in April from the Ecology Center and Lone Tree Council. Skepticism is warranted given the 250 ppt settled on is based on a cancer potency value that is half as protective as the number used at the national level.
In addition, just one day after the announcement of the 250 ppt use for dioxin in soils, EPA released their reference dose for dioxin in soils and the reference dose translates to 50 ppt for non cancer effects. Given EPA active involvement and oversight for decades in Midland, Dow Chemical’s backyard, the agency’s public absence on the 250 ppt did not go unnoticed. More on this in the near future.
Final Comments Site Specific
Below is EPA’s presentation on dioxin, risk and how the agency arrived at the dioxin reference dose that translates to 50 ppt in soil.

The following link will connect viewers with the March CAG meeting. http://lwvflintarea.org/environmental.html
None of it was edited which will hopefully put to rest the concerns of CAG members who thought the worst when confronted with a public meeting being recorded. See the December CAG meeting at the same link.
Again, it is Lone Tree Council’s pleasure to provide this public service along with Tune Productions and the Flint League of Women Voters.
This week at the Detroit Economic Club, Dow Chemical announced yet another philanthropic partnership, this time with the University of Michigan to develop a sustainability program to the tune of 10 million dollars.
A press release issued by the Ecology Center of Ann Arbor highlights some of the skepticism over this partnership. The details of the program and Dow’s influence and control over it, if any, have not been released. Read more »
Lone Tree Council is not always going to agree with the regulatory agencies. We will always ask for the most current and up to date science and insist that science drive cleanup and public health protection — that when in doubt the agencies err on the side of public health.
EPA’s recent release vindicates MDEQ use of the 90 ppt for dioxin in soils.
LTC comments: Science Prevails
Last Friday EPA released the non cancer portion of the dioxin reassessment. Acknowledging the toxicity of dioxin, EPA established a first time ever reference dose for dioxin which is much lower than established by the World Health Organization.
Lone Tree joined our friends at CHEJ along with a broad coalition of other public health, veterans groups and environmentalist calling for the release of this important public health document
Of course, Dow Chemical and the American Chemistry Council continue to whine about the release of this document.
You can read the entire document online. EPA’s findings have significant implications for the GREAT LAKES BAY REGION awash in some of the nation’s highest concentrations of dioxin.
The EPA and Dow Chemical have agreed on an initial clean-up plan for Segment One of the Tittabawassee River Superfund project. This section, which runs through the Dow plant in Midland, is one of the more contaminated sections of the river. At one point this section of the river had over 1,100 outfalls carrying waste water and other pollutants from the plant and into the river. Where most of the project on the Tittabawassee focuses on dioxin and furans, this section has been contaminated with a range of chemicals which include such substances as ethyl parathion (a potent insecticide) and chlorinated solvents.

Late yesterday the EPA, capitulating to industry, announced it would not be releasing the non-cancer portion of the dioxin reassessment. Shameful! Lone Tree Council Press Release below.
