bullet07/23/08 New EPA Midwest regional administrator appointed

The U.S. Environmental Protection Agency has a new regional administrator.  Federal administrator Stephen L. Johnson announced Monday that he appointed Lynn Buhl, a deputy assistant administrator in the Office of Enforcement and Compliance Assurance at EPA headquarters, to the administrator position.

Buhl will replace Mary Gade, who resigned May 1 amid internal fights over dioxin contamination near Dow Chemical Co.'s headquarters in Midland, Mich.

As a Bush political appointee Buhl's tenure may be limited to 6 months depending upon the elections in November. Will recent progress on the Tittabawassee River flood plain clean up come to a screeching halt?  Will Buhl develop a conscious as Mary Gady seemingly did so last year?  Will Dow have any influence on Buhl's actions?  Only time will tell.  Click here for article from Grist Magazine concerning Buhl and her past.

Dow Chemical to clean up dioxin contamination in Saginaw's Riverside Boulevard neighborhood

CHICAGO (July 15, 2008) - U.S. Environmental Protection Agency Region 5 today announced an agreement with Dow Chemical Co. that requires the company to clean up dioxin contamination in the Riverside Boulevard neighborhood of Saginaw, Mich.  Construction work in this neighborhood on the Lower Tittabawassee River is expected to begin in late July and continue through the fall.

EPA's data shows unacceptably high levels of dioxin contamination in yards, the unpaved Riverside Boulevard roadway and in the interior of some homes. 
Last April, EPA took soil samples at the residential properties following discussions and consultation with Michigan Department of Environmental Quality and Michigan Department of Community Health. 

"We are pleased that Dow and EPA were able to reach agreement on the terms of this cleanup," said EPA Region 5 Superfund Division Director Richard Karl.  "EPA will continue to oversee all aspects of the work along Riverside Boulevard in close coordination with MDEQ and MDCH."

The agreement, called an administrative order on consent, includes:
* Excavation of residential yards, then backfilling with clean soil.
* Interior cleaning of homes.
* Remediation of unpaved surfaces on Riverside Boulevard.

Dow's Midland facility is a 1,900-acre chemical manufacturing plant.  Dioxins and furans are byproducts from the manufacture of chlorine-based products.  Past waste disposal practices, emissions and incineration at Dow have resulted in on- and off-site dioxin and furan contamination.  A copy of the administrative order on consent and other documents are at http://www.epa.gov/region5/sites/dowchemical.

bullet06/01/08 EPA responds: Chamber of Commerce statements have little factual basis
As posted in the Saginaw News "My View" column Saturday June 1, 2008

Assumptions without research lead to misinformation

The U.S. Environmental Protection Agency shares the view recently expressed in these pages by Bob Van Deventer of the Saginaw County Chamber of Commerce that protecting the health and safety of residents in the Saginaw Valley environment is a top priority.

However, Van Deventer's presentation of the issues concerning dioxin contamination in the Tittabawassee River system leaves out several important details.

Van Deventer claims that "not one individual has ever been ill because of the effects of furans/dioxins" in the river. This is a striking oversimplification. To EPA's knowledge, no specific study has ever been conducted that supports this statement.

Certainly, in the case of dioxin, delaying action until people actually suffer clinical health effects would be irresponsible.

Considerable evidence shows that adverse health effects are possible and may begin to occur when individuals are exposed at levels not much higher than those expected for the general population. Also, available data show elevated dioxin levels in soils near many private homes as well as in local game and fish in the Saginaw Valley.

Another Van Deventer claim, that "wildlife along the Tittabawassee River is flourishing," has little factual basis. The EPA has never received a work plan for an ecological risk assessment by Dow or Michigan State University researchers that meets the agency's baseline requirements. Furthermore, the MSU wildlife studies to date have not undergone peer review.

Finally, in discussing the University of Michigan's preliminary results from its dioxin exposure study, Van Deventer states that it "clearly showed very little difference in dioxin blood levels" between Tittabawassee River floodplain residents and a test group not living in the area. Again, the U-M study has yet to be fully peer-reviewed.

To conclude anything definitive at this early date would seem to be an attempt to limit further discussion. A final report is not expected until late this year at the earliest.

The studies under way clearly demand the full scrutiny of the scientific and academic communities. The agencies also fully support the concept of new, additional studies of human and ecological health in the area by qualified researchers. To do anything less is to short-change the residents and the health of the Saginaw Valley.

bullet06/1/08 EPA: Agencies consider downstream effect of river restoration

As posted in the Saginaw News "My View" column Saturday June 1, 2008, 2-3 months after it was submitted in response to Horn's My View article of 2/29/08

Agencies consider downstream effect of river restoration

The U.S. Environmental Protection Agency agrees with state Rep. Kenneth B. Horn that all parties with a vested interest in cleaning up the pervasive, long-standing dioxin and furan contamination in the Tittabawassee and Saginaw rivers should work together to resolve this complex problem.

The residents who live along these valuable natural resources have been waiting for decades and deserve to finally see real action.

The EPA is working closely with the Michigan Department of Environmental Quality to accelerate the process and help bolster the state's efforts to compel Dow Chemical Co. to clean up the Tittabawassee River.

To be accountable to the public we serve, the EPA must also provide clarity, context and, in a few instances, corrections regarding some issues that were recently raised by Horn in these pages.

In 2006, Dow assured the DEQ that it would clean up three highly contaminated sections of the Tittabawassee River, but in 2007 the company indicated it would not finish by the end of the year. When Dow proposed two more years to finish work on the section near its Midland facility and made no plan to clean up the section six miles downriver, the EPA exercised its authority under Superfund and ordered Dow to complete all three cleanups simultaneously in 2007.

It is important to note that the DEQ and Dow were already planning to remove dioxin-contaminated soil along the 1,600-foot section three miles downriver from Dow's plant before the EPA got involved.

The plan called for Dow to engineer the riverbank to minimize future erosion. The goal was to allow the river to expand up the bank and reduce its energy during high flow periods.

The U.S. Fish and Wildlife Service also provided expert opinion, and its recommendations were incorporated into the work plan. The EPA's order ensured that the work got done.

Horn made the point that "lots of rip-rap" should be used to keep the banks from eroding.

While the EPA agrees that using some rip-rap is warranted, overuse may concentrate the river's energy and cause problems for communities downriver.

The EPA and the DEQ recognize that extensive work needs to be done to stabilize rapidly eroding riverbanks. However, neither agency considers lining the river with rip-rap an acceptable solution.

It is also necessary to clarify that as a matter of fact, 300 majestic, 100-year-old oak trees were not ripped from the ground during the cleanup.

According to Dow's tree inventory, only three of the 419 trees cut down were oaks. The rest were fast-growing and short-lived cottonwoods and ashes, generally considered to be less desirable. It is highly unlikely that many of them were 100 years old since most were small in diameter indicating relatively young ages.

Certainly, the EPA realizes it is unfortunate that even one tree was cut down, and that is why Dow was required to plant 430 new trees.

The Fish and Wildlife Service recommended that Dow replace the trees with a greater variety of native species because diversity makes the area less susceptible to blight or infestation.

Dow also replaced groundcover in the area with native grasses, an improvement requested by the Natural Resource Trustees.

The EPA could not agree more with Horn that future work should be accomplished in a way that does the least damage possible to the natural beauty of the rivers. The EPA and the DEQ are working together to make sure that even greater care is taken in the future to protect existing vegetation and, when possible, enhance the habitat with natural bank stabilization methods.

FOR IMMEDIATE RELEASE
No. 08-OPA097

CHICAGO (May 28, 2008) - Officials from U.S. Environmental Protection Agency Region 5, Michigan Department of Environmental Quality and Michigan Department of Community Health met with residents of the Riverside Boulevard neighborhood in Saginaw last night to discuss results of recent sampling of dioxin-contaminated soil in the area.

Soil from residential properties in an area along the Lower Tittabawassee River was recently sampled and analyzed by EPA and evaluated in collaboration with MDEQ and health officials. While final data is still coming in, preliminary results show properties with unacceptably high levels of dioxin contamination.

EPA has notified Dow Chemical Co. of the situation and will meet with the company and MDEQ to discuss potential response actions. EPA and Dow successfully negotiated the terms of four hot spot cleanup projects implemented by Dow on the Tittabawassee and Saginaw Rivers downstream of its Midland, Mich., facility last year.

"This cleanup is a high priority as this dioxin contamination is in a residential neighborhood," said EPA Region 5 Superfund Division Director Richard Karl. "We will continue to work with the state agencies to evaluate results of sampling from other residential areas and consider appropriate actions.

The recent sampling project was prompted by Dow's February 2008 disclosure to the agencies of an elevated dioxin level found in a residential soil sample collected by Dow in November 2007. Under the company's Michigan operating license which requires Dow to conduct corrective action for historic releases, MDEQ has been requiring Dow to conduct floodplain soil, riverbank and sediment sampling in and along the Tittabawassee River downstream of Midland.

Dow's Midland facility is a 1,900-acre chemical manufacturing plant. Dioxins and furans are byproducts from the manufacture of chlorine-based products. Past waste disposal practices, emissions and incineration at Dow have resulted in on- and off-site dioxin and furan contamination.

bullet 05/01/08 EPA top Midwest administrator forced out by Bush because of enforcing Dow cleanup

Mary Gade,  based in Chicago, says Bush administration made her quit over Dow Chemical case

  Tribune reporter  May 1, 2008


The Bush administration forced its top environmental regulator in the Midwest to quit Thursday after months of internal bickering about dioxin contamination downstream from Dow Chemical's world headquarters in Michigan.

    snip: For the past year, Gade has been locked in a heated dispute with Dow about long-delayed plans to clean up dioxin-saturated soil and sediment that extends 50 miles beyond its Midland, Mich., plant into Saginaw Bay and Lake Huron.

    snip: Though regional EPA administrators typically have wide latitude to enforce environmental laws, Gade drew fire from officials in Washington last month after she sent contractors to test soil in a Saginaw neighborhood where Dow had found high dioxin levels.

    snip:"There is no question this is about Dow," Gade said. "I stand behind what I did and what my staff did. I'm proud of what we did."

 http://www.chicagotribune.com/features/lifestyle/green/chi-epa-official-resigns_webmay02,0,4655733.story

---- 

 Make no mistake good people of the Saginaw Bay Watershed, Mary Gade was a great asset to the region and to the Saginaw Bay Watershed.

 Harken back to the 1980's and Dow interference with EPA.  For months now Dow has been reaching out to EPA headquarters shopping around for a better deal, a quick-out or an  opportunity to skirt the law. Same thing they've been doing for thirty plus years.

 

Looking forward to the ongoing investigative story by the Tribune. Go to the link and watch the video clip of Joy and Lloyd Cooper who live on the Tittabawassee River in the neighborhood that drew Mary Gade so much fire.

EPA, MDEQ to sample Saginaw residential area for dioxin contamination
 
(Chicago- Apr. 2, 2008) U.S. Environmental Protection Agency Region 5 and Michigan Department of Environmental Quality have begun screening a residential neighborhood in Saginaw Mich., for dioxin-contaminated soil.
An estimated 10 residential properties in an area along the Tittabawassee River will be sampled.  Small plugs from up to 36 inches below surface level will be sent for laboratory analysis. 
Analysis may take two to three weeks.  Once the data is returned, EPA and MDEQ, along with Michigan Department of Community Health, will consider a range of options, including more comprehensive sampling in the area and possible cleanup actions.
"Residential soil contamination is a serious matter," said Associate Superfund Director Ralph Dollhopf.  "At this time of year, children are playing outside again and families are planning gardens.  If action is needed, this project will ramp up very quickly." 
The investigation aims to determine the extent of dioxin contamination present in the neighborhood.  The project was prompted by Dow Chemical Co.'s February 2008 disclosure to the agencies of an elevated dioxin level found in a residential soil sample collected by Dow in November 2007.  Under the company's Michigan operating license, MDEQ required Dow to conduct certain soil and embankment sampling along the Middle Branch of the Tittabawassee River.
Dow's Midland facility is a 1,900-acre chemical manufacturing plant.  Dioxins and furans are byproducts from the manufacture of chlorine-based products.  Past waste disposal practices, emissions and incineration at Dow have resulted in on and off-site dioxin and furan contamination.

bullet 01/04/08  EPA Terminates negotiations with Dow on river cleanup

Maybe there is hope yet.  In our previous update (see 12/22/07 entry below) , the EPA negotiations with Dow seemed to be following a  familiar pattern with a predicted outcome.  Today's EPA Press Release (below) may indicate a fundamental shift in the right direction.  Dow influenced Local and State politicians are preventing the MDEQ and it's hard working staff from accomplishing much other than a few public relations "hotspot" cleanup stunts in a long and protracted process that would take decades to resolve the entire watershed.  In contrast, recent EPA comments indicate they are ready to cut through all the bull and prepared to force Dow to come up with a comprehensive plan that protects human health and the environment.  Only time will tell.

What we need is a cleanup plan that immediately addresses the entire 50 mile river system and the floodplains that surround it.  What's next?  Speculation ( that's all it is at this point since the negotiations are closed to the public) is that the EPA may just hire contractors to perform the necessary cleanup and send the bill to Dow.  We doubt Dow would just roll over and pay, a Federal lawsuit may be in the works and Dow's operating license could be in jeopardy.   We hope it does not come to that, maybe Dow will decide to start to play ball in earnest.

FOR IMMEDIATE RELEASE
No. 08-OPA001

(Chicago, Ill. - Jan. 4, 2008) U.S. Environmental Protection Agency Region 5 today stopped its negotiations with Dow Chemical aimed at a settlement to conduct a study and interim cleanup actions for dioxin contamination in the Tittabawassee River system.

"EPA does not believe that the deal Dow is offering goes far enough," said Ralph Dollhopf, Associate Director for the Superfund Division of EPA's Regional Office in Chicago. "Key issues that are paramount for protecting human health and the environment remain unresolved. EPA simply will not accept any deal that is not comprehensive."

Last October, EPA called for 60 days of negotiations under provisions of the Comprehensive Environmental Response, Compensation and Liability Act, or Superfund. Superfund specifies the process in which a remedial investigation and feasibility study must be conducted, as well as the design and execution of a cleanup plan. Last month, EPA extended its Dec.10, 2007, deadline to resolve remaining issues and reach a final agreement.

"I am extremely disappointed with this outcome," said Regional Administrator Mary A. Gade. "EPA approached negotiations with high hopes and realistic expectations. Our team put in many long hours of good faith efforts that came to an unfortunate end today. EPA is now reviewing its options for ensuring that dioxin contamination in the river system and the Midland area can be fully addressed."

The targeted area begins upstream of Dow's Midland, Mich., facility and extends downstream to the Saginaw River, its floodplains and Saginaw Bay in Lake Huron.

Under Superfund, an investigation and study are necessary to evaluate the nature and extent of hazardous substances, pollutants or contaminants from a site and assess the risks they present to human health and the environment. It would also require that enough data be developed to evaluate a range of cleanup options.

Dow's Midland facility is a 1,900-acre chemical manufacturing plant. Dioxins and furans are byproducts from the manufacture of chlorine-based products. Past waste disposal practices, fugitive emissions and incineration at Dow have resulted in on- and off-site dioxin and furan contamination.

bullet 12/22/07 Dow requests deadline extension

Dow missed the EPA's cleanup 60 day negotiation deadline of December 10, 2007.  The October 10, 2007 EPA press release , EPA to Dow Chemical: 60 day clock to negotiate on Tittabawassee River system cleanup starts today,  stated "EPA may choose to extend negotiations until Jan. 9, 2008, if appropriate".  Is anyone surprised?  Dow always delays everything it can. 

What should concern everyone is that on the surface, this process closely resembles the pattern of the last "negotiation" in 2004 when the Governor Granholm stopped the transparent public process and went behind closed doors with Dow.   Is this just another replay of 2004/2005?    Should we substitute the abbreviation "DEQ" with "EPA" in the timeline below?  Any one seen Dave Camp hanging around the EPA office lately?  We hope not, however with negotiations behind closed doors again, only time will tell.

Click here to view the confidential EPA memo detailing Dow's deceptive tactics accidentally released to the Lone Tree Council as part of a FOIA request.  See 12/7/07  Detroit Free Press story for an interpretation.  Note: there have been two breaking stories in the last 24 hours, the whistle blower lawsuit filed yesterday about Dow submitting flawed data to the MDEQ is unrelated to the leaked EPA memo above. However they both share a common theme: a sneaky and unscrupulous Dow Chemical The Detroit Free Press reports (a few snippets)

EPA found state failed to stand up to chemical giant

With the state's complicity, Dow Chemical Co. has delayed cleanup and misled the public about the dangers of dioxin it dumped decades ago into rivers downstream of its Midland plant, Environmental Protection Agency officials charged in a confidential August internal report.

The memo, obtained by the Free Press, also said Dow impeded state efforts to force a cleanup, concealed data and studies, tried to keep documents confidential that should have been made public and insisted on negotiating cleanup details with Gov. Jennifer Granholm's office, rather than staff of the state Department of Environmental Quality.  ...

The situation has left people living along the Tittabawassee and Saginaw rivers frustrated. Their yards and homes are contaminated with dioxin that continues to wash onto their land during flooding. ...

 

Separately from the EPA memo, a high-ranking Dow employee, whose job was to oversee validation of test results of soil samples tested for dioxin along the river, filed a lawsuit in Saginaw County last month claiming tests by Dow contractors were so flawed that the laboratory doing the validation rejected them and then quit, saying it didn't want to continue validation work for Dow. ...

A revealing memo

The EPA memo accidentally was released within recent weeks to the Lone Tree Council, an environmental group, under a Freedom of Information Act request. ...
 
The memo said that Dow, unlike most companies, has insisted on direct negotiations with the governor and with Chester of the DEQ.
The EPA memo also said:

• Dow had done unapproved studies and collected data without telling regulators. The DEQ fined the firm $70,000 in January 2006 over illegal sampling.

• Political figures, including legislators, have been involved on Dow's behalf, trying to soften standards in the company's favor.

• Dow tried to make dioxin seem less toxic. The EPA issued a press release last month rebuking Dow for statements downplaying the extremely high sample found in the Saginaw River.

• Dow used a dispute process to make documents confidential that should not be. The memo itself is one of those documents. ...

Getting to the truth

In her suit, whistleblower Denney said the independent laboratory double-checking the dioxin results told her in November 2006 that the data from Dow's contractor was badly flawed. ...
 

Denney told her bosses. A week later, they ordered her to stop doing any work relating to the data validation.

The lab rejected the data in a letter Dec. 5, 2006, saying it couldn't validate it.

On Dec. 8, the lab sent Dow a letter terminating its contract, citing a breakdown in procedures. Denney's suit said Dow submitted the bad data to the DEQ in February.

"She's been shut out," said Victor Mastromarco Jr., Denney's attorney.

EPA: DOW TO CLEAN UP DIOXIN HOT SPOT IN THE SAGINAW RIVER

CHICAGO (Nov.15, 2007) — U.S. Environmental Protection Agency Region 5 and Dow
Chemical Co. of Midland, Mich., today signed a consent order to begin an emergency
cleanup of a previously unknown dioxin hot spot on the Saginaw River.

Under the order, Dow must dredge dioxin-contaminated sediments in the Saginaw.
Field work must begin immediately with the dredging to be completed by Dec. 15.

“The extremely high level of dioxin found in the Saginaw River and its possible
consequences warrant immediate action,” said Regional Administrator Mary A. Gade.
“Today’s Superfund emergency order requires action now to eliminate an imminent
and substantial threat to human health and the environment.

“ Friday evening, Nov. 9, Dow notified EPA and Michigan Department of Environmental
Quality of preliminary results of over 1.6 million parts per trillion (ppt) of dioxin in one
sample of sediment taken from the Saginaw River. This dioxin concentration is probably
the highest ever found in the Great Lakes. The sample came from a location a half-mile
below the confluence of the Tittabawassee and Shiawassee Rivers, roughly adjacent to
Wickes Park in Saginaw.

On Sunday, EPA provided Dow legal notice of its potential liability and the Agency’s intent
 to immediately begin cleanup. Under the Superfund law, EPA gave Dow the option to
 perform the cleanup under EPA oversight. On Monday, EPA and MDEQ technical experts
 surveyed the site and met with Dow to discuss cleanup alternatives. On Tuesday, Dow
 notified EPA that it would agree to perform the work under an EPA order.   ....

FOR IMMEDIATE RELEASE

07-OPA217

(Chicago, Ill. - Nov. 13, 2007) Acting immediately on information received from Dow Chemical Co. of Midland, Mich., U.S. Environmental Protection Agency, Michigan Department of Environmental Quality and the company have begun preliminary emergency removal activities at a previously unknown dioxin hot spot on the Saginaw River.

Late Friday, Dow notified EPA and MDEQ of preliminary, unvalidated results of over 1.6 million parts per trillion (ppt) of dioxin in one sample of sediment taken from the Saginaw River. This concentration is 50 times higher than a 32,000 ppt level, previously the highest found in the Saginaw River. It is 15 times higher than any dioxin levels found at hot spots in the Tittabawassee River. This new Saginaw River sample came from a location a half mile below the confluence of the Tittabawassee and Shiawassee Rivers, roughly adjacent to Wickes Park in Saginaw.

"EPA has determined that this emergency work should be performed under an EPA Superfund order," said Regional Administrator Mary A. Gade. "EPA and MDEQ are working closely together on a thorough and appropriate plan to remove this hot spot. Moreover, we must be very cautious to make sure, through laboratory tests, that we determine the extent of this high level of contamination. It may be only one additional hot spot or it could cover a larger area."

Dow discovered the latest hot spot during sampling done according to its own Sept. 14, 2007 work plan, which has not been approved by either EPA or MDEQ.

As a result of EPA Superfund orders in June 2007, Dow is now wrapping up the cleanup of three dioxin hot spots in the Tittabawassee River and should be done by year's end. Those dioxin hot spots along the first six miles of the Tittabawassee River were contaminated at levels up to 87,000 ppt, far above state and federal action levels. The area is prone to flooding and erosion which can spread contamination.

Dioxins are highly toxic compounds that pose serious risks to human health and the environment. EPA's reassessment of the most recent scientific findings on dioxin indicates that it is a more potent chemical than previously understood.

For more information about the health impacts of dioxin and eating fish from the Saginaw River system, members of the public may call the Michigan Dept. of Community Health at 800-648-6942 and the Agency for Toxic Substances and Disease Registry at 312-886-0840.

Dow's Midland facility is a 1,900-acre chemical manufacturing plant. Dioxins and furans come from the production of chlorine-based products. Past waste disposal practices, fugitive emissions and incineration at Dow resulted in dioxin and furan contamination both on- and off-site.

In separate legal actions last week, EPA cited Dow for air and hazardous waste violations at its Midland facility. These involve preliminary findings of violations and Dow has 30 days to discuss resolution of the allegations.

Click here for a biased Dow media spin article released earlier today to preempt
 the EPA report.  Local media bought it up hook, line, and sinker.  TV news had
the Dow spinmister John Musser comparing the find to 6 drop in a 55 gallon barrel
and interviews with fishermen lowering their hook almost directly over the contaminated
 area.  Both articles are using the term "Dioxin-Like" (assume it was a sound bite provided
by Dow) in an attempt to downplay the discovery.  Regardless of the "dow-ese" used by
the media, the samples taken near Wickes park revel dioxin in unprecedented levels and it
is the same Dow DIOXIN found throughout the Saginaw Bay watershed.  Suffice it to say
that this is  "sound science" at it's finest.

Dioxin-Like refers to compounds from a group of halogenated aromatic hydrocarbons that
have molecules shaped like TCDD and produce similar toxic effects, such as certain other
chlorinated dibenzo-p-dioxins (CDDs) and certain chlorinated dibenzofurans (CDFs),
polychlorinated biphenyls (PCBs), polybrominated biphenyls (PBBs),
brominated dibenzo-p-dioxins (BDDs), and brominated dibenzofurans (BDFs).

 

bullet11/09/07 EPA notifies Dow of clean-air & hazardous waste violations

Chicago, Ill. - Nov. 9, 2007) U.S. Environmental Protection Agency Region 5 today notified
Dow Chemical Co. that it has found potential clean-air and hazardous waste violations at
the company's Midland, Mich., facility.


EPA issued a finding of violation under the Clean Air Act and a notice of violation under
the Resource Conservation and Recovery Act. It also issued requests for information under
 both acts.


"The issuance of these notices and requests for information shows that the agency takes
seriously its responsibility of protecting human health and the environment," said Regional
Administrator Mary A. Gade. "Our investigation of this very large facility spanned eight
weeks over a two-year period and included personnel from EPA's National Enforcement
Investigation Center. Today's actions are a product of that investigation."


EPA alleges Dow violated the Clean Air Act by, among other things, failing to follow
regulations aimed at detecting and repairing leaks, as well as failing to conduct a required
stack test. Dow was also allegedly found to be in violation of multiple Resource Conservation
 and Recovery Act requirements for managing hazardous waste.


These are preliminary findings of violations. To resolve them, EPA may issue a compliance
 order, assess an administrative penalty or bring suit against the company. Dow has 30 days
 from receipt of the notice to meet with EPA to discuss resolving the allegations.


EPA said Dow's alleged clean-air violations may have increased public exposure to organic
 hazardous air pollutant emissions including, but not limited to, ethyl chloride, toluene, ethylene,
 perchloroethylene, methanol and hydrogen chloride. Hazardous air pollutants may cause serious
 health effects including birth defects and cancer and may also cause harmful environmental
and ecological effects. These pollutants are also volatile organic compounds and are major
 precursors of ground-level ozone (smog).


Smog is formed when a mixture of pollutants react on warm, sunny days. Smog can cause
respiratory problems, including coughing, wheezing, shortness of breath and chest pain.
 People with asthma, children and the elderly are especially at risk, but these health
concerns are important to everyone.


Hazardous wastes have properties that make them dangerous or potentially harmful to
human health and the environment. They exhibit at least one of four characteristics - flammability,
corrosivity, reactivity or toxicity. They can be liquids, solids, contained gases or sludges and
 can be products of manufacturing processes or simply discarded commercial products like
cleaning fluids or pesticides.

bullet10/23/07 EPA right in urging Dow to speed up work

To the editor (Midland Daily News):

    Your editorial of Sept. 17th entitled "Our View: EPA should finish its work" suggests that
 because the agency's dioxin reassessment is not yet completed, dioxin toxicity remains
open to serious scientific debate. This is simply not true.

    EPA has extensive scientific knowledge on the toxicity of dioxin. Thousands of peer-reviewed
 scientific studies have been published. No matter how you look at dioxin, one fact remains indisputable:
dioxin is a highly toxic compound. In fact, EPA's reassessment of the most recent science indicated
that dioxin is a more potent toxic chemical than previously believed. A recent University of Michigan
study funded by Dow Chemical revealed that people consuming fish from the Tittabawassee River,
Saginaw River and Saginaw Bay have higher than average levels of dioxin in their blood. Any increase
 in the dioxin levels of fish consumers is a health concern.

    For more than 25 years, the State of Michigan has found it necessary to issue consumption
advisories on fish from the Tittabawassee River, the Saginaw River and the Saginaw Bay because
 dioxin contamination extends over 50 miles. EPA believes that the current science on dioxin is
 sufficient to develop cleanup criteria for the watershed. Even without a final dioxin reassessment,
EPA has moved forward with dioxin cleanups across the nation to protect public health.

    The Midland Daily News is right to urge EPA to continue its work on a final dioxin reassessment
and take into consideration comments provided by the National Academy of Science. And EPA is
 right to urge Dow Chemical to continue and accelerate its work to restore the Saginaw Bay watershed
 so that fish consumers will no longer need to be concerned about dioxin in the fish they eat.

FOR IMMEDIATE RELEASE               
No. 07-OPA175

CHICAGO (Oct. 10, 2007) - At a meeting today in Chicago, U.S. Environmental Protection Agency Region 5 formally notified Dow Chemical that it has a limited opportunity to negotiate with the Agency on a settlement to conduct an investigation, a study and interim response actions for dioxin contamination in the Tittabawassee River system. The Midland, Mich., company has until Oct. 17 to decide whether it will negotiate.

The targeted area begins upstream of Dow's Midland Plant and may extend downstream to the Saginaw River, its floodplains and portions of Saginaw Bay in Lake Huron. 

EPA has the authority to call for negotiations under the Comprehensive Environmental Response, Compensation and Liability Act, or Superfund. Superfund specifies the process in which a remedial investigation/ feasibility study (RI/FS), cleanup removal actions and remedy design must be conducted.

"The Superfund law provides a strong mechanism to continue necessary actions to comprehensively and definitively address the issue of dioxin contamination in the river system," said Ralph Dollhopf, associate director of EPA's Regional Superfund Division. "The work begun this summer to address three hot spots in the Tittabawassee River is also being performed under Superfund authority."

Dow's expected RI/FS effort must evaluate the nature and extent of hazardous substances, pollutants or contaminants from the site and assess the risks they present to human health and the environment. It must also provide enough data to develop and evaluate a range of cleanup options.


If the company agrees begin negotiations, Dow will have until Dec. 10 to present EPA with a good faith offer demonstrating its willingness to conduct or finance an RI/FS and design a remedy. EPA may choose to extend negotiations until Jan. 9, 2008, if appropriate. 

Top EPA and Michigan Department of Environmental Quality officials are meeting today in Lansing to discuss their respective roles throughout this process.

Dow's Midland facility is a 1,900-acre chemical manufacturing plant. Dioxins and furans were byproducts from the manufacture of chlorine-based products. Past waste disposal practices, fugitive emissions and incineration at Dow have resulted in on- and off-site dioxin and furan contamination.

 
bullet09/12/07 EPA has had enough, pulling out of current mediation process

The United States Region 5 Environmental Protection Agency has declared the current mediation process between
 Dow Chemical and the State of Michigan broken and is pulling out of the process. 

"EPA believes a more open and transparent process is the best way to make important decisions that will affect
the future health and vitality of the watershed for the people of Michigan and the United States," said Regional
Administrator Mary A. Gade. "Despite the best intentions of all involved, the current process is not working as
effectively as it should and it is time to consider a new approach."

Citizens were denied an open and transparent process back in 2005
 when Lt. Governor John Cherry signed the infamous "framework" agreement. 

What's next?  Will the EPA propose or mandate a new plan, sue Dow for
the missing information, or just walk away?  We doubt it's the latter, stay
tuned.

EPA issues demand for Midland dioxin sampling data

(Chicago, Ill. - Aug. 31, 2007) U.S. Environmental Protection Agency Region 5 today issued a request for information to the city of Midland, Mich., for all dioxin sampling data taken within the city in 2006 and 2007. 

The city of Midland has information that would give EPA a more complete picture of Dow Chemical Co.'s dioxin contamination in that area.  EPA has also sent information requests to two other entities that hold relevant information.

"It appears that the data is obscured by an unusual double blind system that EPA has been unable to obtain voluntarily from the city of Midland," said EPA Region 5 Superfund Division Director Richard Karl.  "The city holds the key to the data and we're requiring them to provide it." 

Today's request is part of a larger investigation of dioxin contamination in the Midland area.  In mid-August, EPA issued two requests to Dow asking for  information on off-site and on-site dioxin sampling conducted by Dow and more extensive data on numerous other hazardous materials produced at the Dow Midland plant.  

Dow began a dioxin cleanup in three hot spots of the Tittabawassee River as a result of EPA orders in late June.  Those cleanups are expected to be completed this year and set the stage for additional work downriver.

The Dow facility is a 1,900-acre chemical manufacturing plant located in Midland, Mich.  Dioxins and furans were byproducts from the manufacture of chlorine-based products.  Past waste disposal practices, fugitive emissions and incineration at Dow have resulted in on- and off-site dioxin and furan contamination. 

bullet07/11/07  READ THIS - Unbelievable, shocking, it isn't just dioxin anymore!!

Speechless.....

A EPA document recently obtained by the Lone Tree Council exposes the TRUE state of the Tittabawassee River and Dows attempts to repeatedly delay addressing the problems.  It's not just dioxin any more folks

It seems we are a true silicon valley now thanks to Dow Corning. Silicon has been found in every soil sample taken.  Not to mention another 29+ dangerous chemicals including Octachlorostyrene , Hexachlorobenzene, Aldrin, Dieldrin, Fhloradane, DDT, Mirex, and Toxaphene. 

But lets not forget about the unprecedented levels of dioxin. The document offers valid scientific references which counter almost every lie Dow has purported as "Sound Science" over the last 5 years.

The contents are mind blowing and the implications staggering. This is a must read for everyone, please download it, print it and pass around (it's 44 pages but everyone of them contains important myth busting facts).   Politicians should pay close attention, the cats out of the bag.

Below are a few of the key points of the document, many more are contained in the document with supporting evidence.

bulletMost of Dow's proposed Scope of Work (SOW) and Remedial Investigation Work Plans (RIWP) are deficient and should not be approved by the MDEQ.
bulletDow is not complying with it's RCRA license
bulletDow's deviation from the EPA's guidelines concerning Human Health Risk Assessments are unacceptable.
bulletDow's deviation from the EPA's guidelines concerning Ecological Risk Assessments are unacceptable.
bulletDow's lack of progress in completing their Immediate Response Actions (IRA) is unacceptable.
bulletDow did not include any of the several hundred hazardous chemicals and byproducts produced in it's plants history, the EPA wants a revised RIWP which includes them.
bulletDow demonstrates a pattern of missed deadlines and incomplete corrective action document submittals to the MDEQ, this is a violation of their RCRA License.
bulletDow has failed to report all environmental monitoring data and has inappropriately applied confidential status to much of the data.
bulletThe EPA has major concerns about the Geomorph studies which have many deficiencies and feels the process has not been fully proven.
bulletSilicon has been found present in all soil samples and could be an explanation for the unusual distribution of dioxin and furans in the environment.
bulletEPA believes the 1986 flood caused a release of hazardous chemicals from Dows waste water treatment facility.
bulletEPA is very concerned with 29 chemicals that have been found in the sediment and fish that have been produced by the Dow plant over the years.
bulletDow is manipulating chemical concentration data in it's studies.
bulletDow's Human Health Risk Assessment (HHRA) cite scientific literature in a very selective manner, ignoring recent cancer and other studies which offer contrary outcomes.
bulletThe Dow TCDD Worker study they cite so often is flawed and the outcome meaningless
bulletEPA considers Dow's selective citations to scientific literature unacceptable.
bulletEPA has significant concerns with human dioxin exposure through the food chain pathway.
bulletBecause of the risk to human health, the EPA considers Dows plans to do additional studies before taking remedial action unacceptable.
bulletThe University of Michigan needs to release the raw data from it's Dioxin Exposure study to the EPA and MDEQ.  This can be done without revealing the identity of the participants.
bulletThe EPA believes the University of Michigan  has not been cooperating in producing information to the EPA and MDEQ and therefore wants the MDEQ to investigate why.
bulletDow is not meetings it's time lines and needs to be held accountable in order to keep its RCRA license.

Below are a few snippets from the document:

Dow, however, is conducting its remedial investigation of the Saginaw Bay watershed without approved or enforceable compliance schedules in conflict with the terms and conditions of Dow’s RCRA Permit. ...

U.S. EPA is concerned that Dow’s ecological risk assessment (ERA) is inconsistent with current Agency guidance and the typically accepted methods for conducting such risk assessments. ... U.S. EPA does not believe that ecological risk has been adequately addressed by Dow in the revised RIWPs. ... This concerns U.S. EPA because it is known that individuals within a population can be adversely impacted by contaminants without observed population-level effects. ...  levels of dioxin and furan contamination in the Saginaw Bay watershed through the timely implementation of Interim Response Actions (IRAs) as required by Dow’s RCRA Permit. ... U.S. EPA believes that hazardous constituents are actively migrating downstream from Dow’s facility into Lake Huron. ...  U.S. EPA does not consider Dow’s description to be complete given the scope of Dow's chemical operations in Midland, Michigan. The limited information provided by Dow to MDEQ in the revised RIWPs is problematic. ... U.S. EPA believes that the record in this matter demonstrates a pattern by Dow of missed deadlines and the submittal of incomplete corrective action documents to MDEQ (see Dow Off-Site Corrective Action Activity Table below). U.S. EPA considers these actions by Dow to be inconsistent with the requirements of Dow’s RCRA License. ... Failure to Report all Environmental Monitoring Data and Improper Application of Confidential Status to Data ...  This ongoing failure to provide data within time frames specified in Dow’s RCRA permit continues despite the fact that Dow was issued a Notice of Violation (NOV) by MDEQ for a similar series of violations on September 19, 2005. ... U.S. EPA also has significant concerns with the agreement between the City of Midland and MDEQ to allow Dow to partially shield corrective action data gathered within the City of Midland from public disclosure. U.S. EPA considers the holding of what would normally be publicly available corrective action data in a confidential manner by a third party not subject to the terms and conditions of Dow’s RCRA License to be inconsistent with the recordkeeping and reporting requirements of Dow’s RCRA License. ... Nowhere within Section II.L (Recordkeeping and Reporting) does Dow’s RCRA License provide for the selective or partial reporting of data by Dow. ...  A fundamental component of the GeoMorph process, as explained by ATS, is real-time remediation.

U.S. EPA does not agree with the assertion that the GeoMorph process has been fully proven at this site. ...  While Dow has provided a relatively detailed history of Dow's historic chlorine production at Section 3.3.1.1 of the TR RIWP, Dow provides virtually no additional specific information, other than a list of products organized by decade(s), in the revised RIWPs concerning the many hazardous constituents potentially released by Dow to the Saginaw Bay watershed. U.S. EPA does not consider Dow’s description to be complete.  ... constituents from the Dow Corning facility may have potentially affected the distribution of contaminants from Dow’s Midland facility within the Saginaw Bay watershed. ... Dow’s characterization of the hazardous contamination in the Saginaw Bay watershed, therefore, will not be complete without an understanding of the historic operations and waste management practices of the Dow Corning facility whose operations were, and are, intertwined with those of Dow’s Midland facility. ... In 2004, the Superfund Innovative Technology Evaluation project conducted by the Battelle Memorial Institute identified silicone compounds in all of the soil samples taken from the TR. U.S. EPA believes the presence of silicones in the soils and sediments of the Saginaw Bay watershed to be unique and, therefore, could be an explanation for the unusual distribution of dioxins and furans in the subject environment.  ...  Dow does not provide a detailed discussion of the 1986 flood event on the Tittabawassee River and the potential releas
