Lawyers  clarifies questions about Priority 2 documents

Residents who own property classified as Priority 2 should receive a letter soon about the   AKT Peerless mailings sent to them a few weeks ago.  The letter clarifies a number of questions  concerning the "Residential Property Use Activity" and "License Agreement" documents and offers suggestions on how to respond.  The letter is being sent by the law firms, Stueve-Siegel-Hanson-Woody and Trogan &Trogan.  These firms have been appointed by the Saginaw County Circuit Court as counsel in the Class Action lawsuit against Dow Chemical (currently in Appeal).

A few excerpts (be sure to click on the link below to read the letter for accurate details):

bulletFilling out and returning the "Residential Property Use Activity" document is entirely voluntary according to the MDEQ.
bulletIf you decide to complete and return the document to   AKT Peerless, consider adding the language mentioned the the lawyers letter.
bulletThe "License Agreement" must be completed to be eligible for Priority 2 mitigation measures.
bullet If you decide to sign and return, consider adding the language mentioned the the lawyers letter.
bulletIf you already returned either of the documents to   AKT Peerless, consider following the instructions mentioned in the lawyers letter, you can still amend, cancel, or ask for them back.
bulletIf you have any questions, contact Sherry Berry at 816-714-7100 or Tara Inzerillo at 816-474-8100.
bullet Click here to view the actual lawyer letter (pdf format), print and share with those who do not have a computer.

TRW note: Some of the mitigation measures being offered by   AKT Peerless may temporary reduce dioxin exposure risk IF performed properly, the decision to sign or not sign is entirely up to the resident.  See the 3/10/06 story below for more information on the lessons learned from the Priority 1 residents.

Property appraisals of contaminated properties is a complex process

Estimating the impact of dioxin contamination on Real Estate sales and value is not a simple process as some would have us believe.  Traditional appraisal processes used to evaluate a single property are limited in their ability to accurately determine the impact on a properties value when many properties in the area are contaminated.   What homes sell for in relation to the asking price is interesting, but if the asking prices are less than they would be without the contamination, then the survey results are essentially meaningless.   A few telephone calls and selected property records combined with self-serving comments of real-estate agents do not paint a fair picture of the market along the Tittabawassee or the impact of the contamination on our property values.

All of this is especially true when you have a Fortune 50 company in your midst spending millions of PR dollars with who knows who to cloud the issue.  A local wealthy individual making false promises and throwing good money after bad combined with real-estate agents downplaying the hazards of dioxin may have created the illusion for some that home sales and property values are unaffected.

Is this why people buy homes in areas with dioxin contamination at levels that scientists of the EPA, WHO, CDC, ATSDR, MDEQ, MDCH and almost every other respected health agency in the world consider hazardous to the health of humans, especially their children?  A recent MSU study found 71% of local residents consider dioxin in the flood plain to be a moderate to high risk to their health.  The MDEQ recently announced that people who do not try to reduce their exposure to flood plain soils and fish consumption can increase their dioxin levels by up to 3,900%.

We wonder if the local reporters called on residents who attempted to sell their property but took them off the market after fruitless attempts to sell.  We wonder how many others attempted to get a representative of the local tycoon to make an offer on their property and where either ignored or never received a call back after the initial encounter.  Both are examples of actual experiences and represent the true reality "reality" in the Tittabawassee flood plain.  

Viable, science based, peer reviewed processes for contaminated property appraisals have been available for years.   The methods used by a local news paper do not appear on anyone's list of approved protocols and are misleading.  Licensed Real Estate agents should be familiar with the UNIFORM STANDARDS OF PROFESSIONAL APPRAISAL PRACTICE, specifically the Advisory Opinion 9, "The Appraisal of Real Property That May Be Impacted by Environmental Contamination".  Evidently our local bunch have chosen to ignore them.  

Fortunately, experts in the field of contaminated property appraisals can be found at companies such as Greenfield Advisors.  GA has published many papers on the subject.  Visit their web site and check out the "Publications" page for all the details.  Below are a few excerpts:

How to increase your dioxin levels 3,900%
Answer: Live on the Tittabawassee River and ignore the MDEQ/MDCH Soil, Fish, and Wild Game advisories.

Click to enlargeTittabawassee River residents who are considered "Priority 2" properties in accordance to Dow's Interim Remedial Actions demanded by the state received their information packets in the mail this week.  All of it is very informative, especially on page 10 and 11. State toxicologists have created a graph comparing levels of exposure in different scenarios.  For instance, a person living in the floodplain who tries to limit exposures through dust inhalation, etc., and only eats one meal of walleye per month has a 320% increase in exposure compared to someone who doesn't live in the contaminated area.  Someone who does not try to reduce their exposure and eats 8 meals of sports fish per month have a 3,900% increase in exposure compared to a person not living in an area like ours.  Take a look, click on the graph above to enlarge.

A through explanation of the above graph can be found in the MDEQ pamphlet:

bullet Dioxin and Furans: Reducing exposure at home (includes the above graph)

Additional pamphlets included in the priority 2 package:

Priority 1 lessons learned, Priority 2 residents take note

First of all, contrary to media reports, the Priority 1(P-1) and Priority 2 (P-2) Interim Response Activities (IRA) performed by Dow and AKT  Peerless are NOT a "cleanup" plan.  Their original intent was to temporarily reduce dioxin exposure to residents who live in the contaminated flood plain, the IRA's are measures that Dow may be required to repeat time and time again as the river floods redistribute the dioxin contaminated soils.   Based on comments of others who have participated in the P-1 IRA, it is our opinion that most of these activities are more of a Dow public relations campaign than anything else.  We are not saying you should not participate, some of the activities may temporarily reduce your exposure if performed properly.  Use your own judgment and consider the following when you make your decision:

bulletAnnette Lucas, the AKT Peerless employee who spearheaded the P-1 IRA last year has left the company.  Rumor has it her replacement is Melissa Robishaw.
bulletWhen speaking with a P-1 resident, Melissa indicated that "things will be different" this year for the P-2 residents and "they" will not be handing out services to everyone.  It's possible the only IRA you receive is the mailing packet sent out this week.
bulletNot everyone can be "serviced" at once, there are approximately 500 P-2 properties, P-1 had about 140 or so. So start planning early, work stops for the winter. 
bulletDo NOT assume AKT Peerless will swoop in and take care of everything without your participation.
bulletAKT Peerless is an Environmental Engineering firm hired by Dow to hire subcontractors from the area such as lawn care or nursery firms to perform the actual work.
bulletBefore meeting with AKT Peerless, do the following:
bulletBased on how you use your property, determine exactly what you want done and put them in written form using sketch's/pictures/lists and express your needs to the AKT Peerless P-2 manager.
bulletIf you do not do the following, it's unlikely anything you ask for will be done properly:
bulletPoint out the problem areas to the P-2 manager
bulletDocument problem areas with the P-2 manager.
bulletRe-explain the problems in minute detail (show them your documents) to all work crews that show up.  Every time!!
bulletSupervise the work is completed to your satisfaction.
bulletCall the P-2 manager back as often as it takes to get things right.
bulletThe MDEQ is overseeing Dow's implementation of these activities, you may request an audit of the Dow proposal by the MDEQ at any time, contact Allan Taylor at taylorab@michigan.gov
bulletIf you want dioxin sampling performed on your property, ask for it otherwise Dow may not even mention it's an option (you have to complete and sign the "License Agreement" received in your packet, more on that later).
bulletBe prepared for the following:
bulletWork crews may just show up without notice and have little idea of what they are actually supposed to do.  Patronizing work crew owners may follow to smooze and shake hands and utter platitudes about how they "cleaned up" your dioxin problem, indicating it is no longer an issue.
bulletIf you are to receive indoor IRA's such as dusting, they will not move anything out of the way, it's your responsibility.  The MDEQ "Reducing Exposure at Home" brochure recommends "When dusting and cleaning inside the home, avoid creating airborne dust (to minimize breathing and swallowing dust) ...". 
bulletObserve how the work crews dispose of contaminated material, it is not acceptable to pour contaminated wash water down your sink, drain, or toilet as was done at some P-1 properties.
bulletMost members of work crew will know nothing about dioxin or proper techniques to reduce exposure and will do whatever they think is "good"  or "pretty" if you do not intervene. (Example from P-1: a quarter inch of new dirt spread over exposed contaminated soil is NOT acceptable).
bulletDo not consider the work crews knowledgeable about the situation, most of them know nothing of the real facts (the EPA, ATSDR, CDC, WHO, MDEQ, and MDCH versions, not Dow's propaganda) and will offer opinions that range from gross misinformation to the absurd (example from P-1: dioxin comes from trees).
bulletTake a controlling stance, instead of just getting out of their way & expecting the work crews to know what to do. 
bulletTake before and after pictures.
bulletThe "License Agreement" included in the packet must be completed to be considered for any P-2 IRA  work.
bulletThe agreement authorizes Dow to access your property for the purposes of conducting soil sampling and survey work.
bulletThe agreement authorizes the MDEQ to access your property for the purposes of overseeing the Dow sampling and surveying.  Consider asking that the sampling ALWAYS be supervised by the MDEQ and that the techniques used meet EPA standards, not Dow's.  Always ask for the names and credentials of everyone who visits your property, the license states the work will be done "at times convenient to the Resident".
bulletThis is a legal document, you may want your lawyer to review, so do it now.
bulletTo be considered for P-2 IRA, you must complete the enclosed "Residential Property Use Activity Survey" or "Agricultural Property Use Activity Survey".
bulletThe State officials contributed to the design of the form but indicate they are not really sure how the information will be used by Dow.
bulletMany of the questions require a simple Yes or No answer which in our opinion cannot be properly answered if you have been following the States Soil, Fish, and Wildlife advisories/recommendations.  To do so based on your current state may require a NO answer which is misleading, you want to carry out all these activities on your property but the contamination prevents it.  The form does not provide for comments or clarifications, will they pay any attention to what you scribble in the margins or attach as separate documents?  If you answer No, will your property be disqualified?  Will the information be used in other ways at a later date?
bulletAny information provided on the form must be provided to the MDEQ and therefore may be subject to a Freedom of Information Act (FOIA) request and become publicly available.

bullet Dow has 60 days from March 2nd to resubmit work plans to correct the 26 deficiencies noted
bulletMidland Daily News editorial
bullet The government seems to be asking The Dow Chemical Co. if it is serious about addressing local dioxin contamination.
bulletShame on you Mr. Musser
bullet Dow’s John Musser argues that Dow Chemical is not responsible to EPA. This is a bare faced lie and a deliberate attempt by Mr. Musser to deflect criticism of Dow pathetic work plans
bulletDow Remedial Investigation Work Plans for the Saginaw River NOT submitted 
bullet Dow was to submit work plans for the upper Saginaw River by March 1 2006. It didn’t happen.  Lone Tree Council, using the Freedom of Information Act, requested a copy of the work plans. DEQ responded with the following statement.  “The State of Michigan DEQ & Dow Chemical Company have mutually agreed to defer submission of the Conceptual Work Plan for the Upper Saginaw River”.
bulletDow blow's their own horn, We can't hear you Mr. Liveris
bullet Recent Dow propaganda states they are recommitting to Responsible Care in the chemical industry.  Dow is making unprecedented profits and is financially structured to meet their environmental responsibilities. They choose not to because they can. The big mistake we make is assigning any sense of ethic or social responsibility to this particular corporation. 
bulletMarch 15th deadline for public comment on Dow RIWP
bullet Lone Tree is preparing comments on the Dow’s work plans and we will send them out soon. We did ask DEQ for a public Technical Information Meeting ( TIM)  sometime after the deadline to discuss the Notice of Deficiency and how they will be remedied. It is imperative the sampling season and data collection not be delayed because of Dow’s refusal to submit adequate work plans. We remain optimistic that the DEQ will agree to hold a TIM.

DEQ issues Dow Notice of Deficiency: 60 days to respond

On March 2, 2006, the MDEQ issued Dow Chemical it's official Notice of Deficiency concerning Dows proposed Remedial Investigation Work Plans (RIWP) for the Tittabawassee River and Midland.  Dow has 60 days to resubmit work plans to correct the 26 deficiencies noted.  Many of the MDEQ demands parallel the EPA's objections (see related stories below) and are intended to force Dow to use  principals and scientific methodologies acceptable to the EPA and other regulatory agencies rather than the Corporate Science they are so fond of.  Dow is well aware of the proper way to comply with regulations, they chose to ignore them to force another 60 day delay in the process.

DEQ agrees with EPA's criticism of Dow work plan

The MDEQ issued a DRAFT Notice of Deficiency to Dow's Remedial Investigation Work Plans on 2/10/06 which basically agrees with all of the EPA's criticism (see related story 2/21/06 story  below).  The final version to be sent to Dow is expected some time in the next few weeks which will start the EPA's recommended 60 day window for Dow to resubmit amended RIWP's.

Excerpt from MDEQ email: "MDEQ “high level” review comments on the TR RIWP and the Midland RIWP submitted by Dow to MDEQ for review and approval. Please note that the MDEQ is in substantial agreement with U.S. EPA’s comments of February 10, 2006 (also attached) and that the comments below are intended to supplement the U.S. EPA comments. These comments are not intended to be all inclusive. These do represent significant deficiencies that must be addressed in order to obtain MDEQ approval and to move forward with a more detailed technical review." 

Topics Include:

bullet

Major Items and Issues for the Tittabawassee River and Midland RIWPs (TR RIWP and Midland RIWP)
bullet

The RIWP must contain a single comprehensive schedule that consolidates the major work activities proposed by the RIWP and associated studies.

bullet

In addition to lacking detail on the overall RI process, the new schedule proposed in the RIWP is not consistent with the schedule in the approved Scope of Work for the Tittabawassee River.

bullet

The RIWP Conceptual Site Model or Current Conditions report does not address or list the specific exposure pathways that are currently known to be present or identify other exposure pathways that may be present and require investigation.

bullet

The RIWP does not address comments previously provided to Dow on the PCOI identification process.

bullet

Many concerns with proposed collection of soil samples randomly distributed throughout the Tittabawassee River floodplain for PCOI identification and to provide data to develop a geospatial model to predict the distribution of dioxins and furans in the floodplain.

bullet

If Dow proposes to conduct geospatial modeling as part of the RIWP, the following information must be directly included in the work plan for review and approval:
bullet

The statistical basis for the sampling grid (the point to area spatial representation) and a clear basis for proposing the sample population(s) for the study areas.

bullet

The processes and equations upon which the model is built.

bullet

The process by which the model will be calibrated to the n samples.

bullet

Verification of the model by demonstrating that it also matches existing data.

bullet

Dow is proposing to collect 25 sediment samples for PCOI identification (see comments in number 4) and to test their theory that sediment levels of dioxin are “random.” The workplan needs to provide detail to describe how the hypothesis of randomness is to be tested and at what scale this hypothesis may apply

bullet

The RIWP does not address Preliminary Feasibility Study Planning or data needs as required by III.F of the approved SOW and as discussed in Dow’s “Performance Based Approach” proposal.

bullet

The RIWP needs to specifically include mapping and sampling of erosional areas (e.g. cut banks).

bullet

The Midland PCOI investigation strategy needs to be reevaluated as indicated by U.S. EPA.

bullet

DQOs These will need to be revised to reflect required modifications to the RIWPs.

bullet

Major Items and Issues for the Human Health Risk Assessment Work Plans (HHRA WP)
bullet

Review and approval process for components of the HHRA WP.

bullet

Preliminary Conceptual Site Model (PCSM)

bullet

Identification of Exposure Pathways

bullet

Exposure Data Collection

bullet

Exposure Inputs to HHRA Equations

bullet

Toxicity values

bullet

Toxic Equivalency Factors (TEFs)

bullet

Screening Level Risk Assessment (SLRA)

bullet

Forward-looking Probabilistic Risk Assessment

bullet

Area Wide Cleanup Criteria (AWCC) and Site Specific Cleanup Criteria (SSCC)

bullet

Soil and Sediment Concentrations related to food-chain pathways

bullet

Identification of other PCOIs

bullet

Citations and/or references need to be included for all applicable Part 201 regulatory requirements or EPA guidance

bullet

Sequence of proposed HHRA WP components

bullet

A review and approval process for the individual workplan for each component of the HHRA work plan is necessary.

bullet

The PSCM must describe known and expected human and ecological exposure pathways for each land use including transport mechanisms or migration routes known or expected to occur between environmental media (e.g., soil and sediment) and receptor populations.

Lone Tree/TRW Dioxin Update

The recent work plans submitted by Dow Chemical to MDEQ which were at the center of the recent DEQ- Dow meeting on Feb. 9th, have been reviewed by EPA Region V  and the review is highly critical of Dow’s plans (see the next story below for details and a link to the EPA document).  The work plans are of highest priority because they determine how the state proceeds with cleanup.

 

Failing to pass scientific scrutiny within EPA Dow once again submits plans so deficient as to be transparent. No company with the resources that Dow has can consistently submit plans so inadequate and so lacking unless it is by design. Like the Consent Order in 2002, the Risk Assessment in 2002, the Scopes of Work in 2003 and the IRA’s, Dow’s intentions are to deliberately:

 

bullet
Ignore compliance with their license
bullet
 Delay defining the extent of their contamination
bullet
 Deny the toxicity of dioxin
bullet
 Rewrite the science to benefit them
bullet
 Rewrite the laws that govern them
bullet
 Delay Cleanup

 

It’s a legitimate question to ask if “voluntary corrective action” really works or if it’s just a burden on the taxpayers as it drains resources and tax dollars within our budget strapped DEQ. Not to mention the natural resource and public health implications associated with deliberate delays created by a corporation that has no interest in being responsible. Under the provisions of voluntary corrective action the State of Michigan has spent years working with Dow to bring them into compliance. Folks it's not working!

EPA finds Dow IR Workplans "Critically Deficient"

In a recent memo to the MDEQ states:"...the United States Environmental Protection Agency, Region 5 (EPA or the Agency) has conducted a preliminary review of the Tittabawassee River and Floodplain Remedial Investigation Work Plan (T-RIWP) and the Midland Area Soils Remedial Investigation Work Plan (M-RIWP) submitted to Michigan Department of Environmental Quality (MDEQ) by the Dow Chemical Company, Midland, Michigan (Dow) on December 29, 2005. As detailed in the attached comments,the Agency has determined that the T-RIWP and M-RIWP (RIWPs) are critically deficient".

A few excerpts:

bullet

The RIWP deficiencies set forth in EPA’s comments need to be addressed by Dow prior to initiation of a more comprehensive review of these documents.

bullet

Dow’s Human Health Risk Assessment Work Plans are fundamentally flawed, and it would not be a wise or efficient use of either agency’s resources to attempt to approve them with modifications in their current form.

bullet

EPA requests that MDEQ require Dow to promptly address the deficiencies detailed in the attached comments and then require Dow to resubmit amended RIWPs to the State of Michigan no later than sixty (60) days from the date that Dow is provided written notice of the subject deficiencies.

bullet

EPA also requests that MDEQ not approve either RIWP, in full or in part, until all of the requested changes are made by Dow and such changes have been reviewed and approved by MDEQ.

bullet

The sampling protocol set forth in the T-RIWP by Dow to determine the nature and extent of hazardous constituent contamination in the Tittabawassee River (TR) sediments is severely inadequate.

bullet

Existing data is insufficient to support Dow’s conclusion that sediment contaminant concentrations in the TR are random and that no consistently elevated areas of contamination exist within the TR sediments. Dow’s proposal of one sediment sampling location per mile is very likely to be orders-of magnitude greater than the actual distance of spatial correlation.  Consequently, analytical results obtained from sampling locations with a separation of one mile would have a strong tendency to exhibit the unpredictability postulated by Dow.

bullet

EPA does not consider geospatial modeling as an acceptable substitute to an empirical characterization of the nature and extent of contamination. ...  EPA recommends that MDEQ require Dow to implement a significantly more comprehensive and intensive sampling program that will establish the nature and extent of the PCOIs within the TR floodplain.

bullet

Dow’s proposal for three surface water sample locations in the TR to be sampled   during a base flow and flood event is inadequate.

bullet

EPA requests that MDEQ require Dow to undertake the following four sequential steps in order to properly characterize the TR and Floodplain:

  1. Completion of a thorough PCOI study (Principle Contaminants of Interest)

  2. Completion of a thorough geochemical study on all of the identified PCOIs (or all PCOI chemical groupings)      of interest

  3. Completion of a  pilot characterization study to determine horizontal sampling grid interval for both the River  sediments and the floodplain soils
    bullet

    Sampling for both PCOIs and geochemistry should be performed on transects across the river at a minimum of 1/4 mile intervals (approximately 100 transects).

    bullet

    EPA recommends that the sampling locations be gridded on a one hundred (100) foot interval throughout both the floodplain and the River, extending from one side of the one hundred (100) year floodplain to the other.

  4. Completion of a full characterization study including the preparation of depth-based contaminant-concentration contour maps for all identified PCOIs

bullet

EPA recommends that, at a minimum, the final work products of the T-RIWP characterization process include the following:
bullet

90 ppt TEQ boundary line map (vertical and horizontal).

bullet

Depth based concentration contour maps with a 100 ppt TEQ contour line.
bullet

0-6 inch surface TEQ concentration contour map.

bullet

TEQ concentration contour maps for all underlying 1-foot vertical compositing intervals

bullet

Comparable boundary lines and maps should be produced for all other PCOIs.

bullet

Dow’s proposal in the M-RIWP to delay Phase II sampling until 2008 is not acceptable to EPA.

bullet

... this multi-year process of developing, reviewing and approving these risk-based and/or area-wide criteria will preclude a thorough evaluation of the extent and intensity of the D/F contamination within the City of Midland. Such a delay is not acceptable or appropriate in light of the significant potential risks posed by the known hazardous constituent contamination in the City of Midland.

bullet

EPA requests that MDEQ require Dow to include in the M-RIWP’s proposed Phase II sampling plan, soil sampling at the Dow Midland facility.

bullet

The Human Health Risk Assessment Work Plans (HHRAWPs), as proposed by Dow in the RIWPs, do not comply with EPA risk assessment policy and guidance and, therefore, cannot be approved by EPA.
bullet

EPA requests that MDEQ require Dow to identify in the RIWPs the likely and potential specific pathways of human exposure to PCOIs in the Midland soils and TR soils and sediments. Such exposure pathways will likely include direct contact to PCOIs and indirect exposure to PCOIs after fate and transport processes have occurred, e.g. consumption of contaminated fish and/or wildlife. In addition, Dow must identify appropriate high-end receptor populations, such as subsistence fish and wildlife consumers and native American populations.

bullet

Dow should be required to identify the specific data which will be collected and used to support the exposure assessment portion of the HHRAWPs. In addition, Dow should be required to explain how the PCOI concentrations will be incorporated into the HHRAWPs to determine levels of risk and used for comparison to Cleanup Criteria.

bullet

Dow's proposal, in the HHRAWPs, to use probabilistic methods for deriving dose-response parameters for the PCOIs is unacceptable.
bullet

Dow implies that the methodology for applying probabilistic risk assessment (PRA) to dose-response data in HHRAWPs would be straightforward, but this is far from the case.
bullet

For example, Dow does not explain whether the PRA analysis will use human studies in addition to animal bioassay studies. If data from one animal species were to show a clearly defined (and human related) dose-response effect (positive), but the  data from another species did not (negative), it is not clear in the HHRAWPs whether Dow would give the data from the positive species more weight than the data from the negative species, in accordance with EPA policy and guidance.

bullet

EPA does not believe that Dow has proposed an adequate or widely accepted methodology for constructing Probability Distribution Functions (PDFs) for dose-response data. Because the establishment of dose-response data and toxicity factors for chemicals has national implications, EPA cannot approve requested deviations on a site-specific basis. National standards are based upon scientific consensus and are established by EPA Headquarters in Washington, D.C. Recognition and use of these standards are a necessary prerequisite to national consistency. As a result, EPA, Region 5 cannot approve a PRA which includes probabilistic methods for deriving dose-response parameters.

MDEQ / MDCH respond to misinformation

Steven E. Chester and Janet Olszewski, Editorial posted in Midland Daily News 02/19/2006

A recent forum piece by Dr. Richard Reitz, former toxicologist for Dow Chemical, suggested that the Michigan Department of Environmental Quality (MDEQ) has failed to use science to guide our decisions concerning the cleanup of historic dioxin contamination in the Midland area. This assertion is false, and with the great deal of progress we have made over the past year to move this process forward, it is disappointing to see these misleading statements made.

The MDEQ, along with our partners at the Michigan Department of Community Health (MDCH), have a clear goal in mind: Protecting the environment and the public health of those affected by dioxin contamination. Our combined efforts are the work of some of the top scientists and health experts in the state, all of whom have dedicated their careers to serving the people of Michigan. To suggest that they have used anything but the highest degree of scientific review to guide their work simply demonstrates a lack of understanding as to how our agencies fulfill our commitment to the public.

Dr. Reitz makes a number of misstatements throughout his article, all of which have been refuted by many people time and again, but which warrant additional response here. First, he states that soil samples that have been taken throughout the area have shown inconsistent results, causing us to simply make assumptions on the area of contamination. This is simply not true.

The results from sampling done along the Tittabawassee River have consistently shown elevated levels of dioxin within the March 2004 floodplain area. Dow has acknowledged this in their recently submitted remedial investigation work plans that specifically state, "Éthese results suggest that the 8-year flood boundary may be a good predictor of whether or not TEQ (dioxin & furans concentrations) will fall below 90 parts-per-trillion." This does not suggest that there are not elevated levels of dioxin outside of the floodplain area, however, it clearly shows that existing data provides the basis to make a consistent and reasonable estimate of the scope of contamination.

Dr. Reitz states that scientific experts from around the world disagree with our cleanup criteria for dioxin. Again, this is not correct. He cites the Agency for Toxic Substances and Disease Registry (ATSDR) level of 1,000 ppt for dioxin exposure. The ATSDR 1,000 ppt level is an action level, meaning that they have determined that levels of dioxin in soil should trigger measures to interdict or prevent exposures. The action level of 1,000 ppt is considered protective by ATSDR only when it is combined with site-specific evaluation of levels such as Michigan's 90 ppt, which is a preventative level meant to safeguard the long term health of those living in contaminated areas. A number of other states go well below Michigan's risk level. Oregon, for example, has a residential soil cleanup level for dioxin of 3.9 ppt, while Massachusetts' is 4 ppt.

Dr. Dennis Paustenbach is quoted by Dr. Reitz as concluding that persons living near concentrations of dioxin in soil containing 1,000 ppt have no greater than a 1 in 100,000 chance of contracting cancer due to their exposure. Actual risk evaluations that have been conducted by federal and state agencies for people residing on property with soil concentrations at 1,000 ppt indicate that risk to be far higher; in fact, the U.S. Environmental Protection Agency has estimated that the 1,000 ppt level represents a 2.5 in 10,000 cancer risk. Those numbers certainly can not be overlooked.

As a toxicologist, Dr. Reitz should also understand that the MDEQ and MDCH have acted in accordance to common scientific practice in relying on cancer studies in rats when setting cleanup standards. In fact, we relied on a Dow Chemical Co. rodent study to derive an appropriate soil cleanup criterion for dioxin. This study has been and continues to be widely used while states and other organizations await finalization of the EPA's Dioxin Reassessment, which preliminarily estimates that the cancer potency for dioxin is approximately 10 times higher than previously estimated.

Dr. Reitz also appears to be under the impression that the U of M Dioxin Exposure Study will establish a soil cleanup level, something that it was not designed to do. The U of M study is an exposure investigation that we hope will provide valuable information, however, it is not a health study and is not designed to determine a health risk based on soil concentration.

Perhaps most troubling, however, is Dr. Reitz' claim that the work done by the MDEQ and MDCH does not undergo independent scientific review. Being public agencies, our work goes through extremely thorough public and scientific review on a regular basis. We work very closely with the U.S. EPA, ATSDR and other state and federal agencies, and our scientific processes are consistent with those of the World Health Organization, the International Agency for Research on Cancer, and others. We have in the past, and will continue to have independent scientific reviews conducted through Toxicology Excellence for Risk Assessment (TERA), a peer review organization used by Dow Chemical, among many others in our state.

All of our work is guided by the very best scientific research, methodologies, and processes accepted by the scientific community, and we make great efforts to ensure that we are transparent in how that work is done, and that it is understood by the public.

Our ultimate goal is to develop a remediation plan that is protective of human health, the environment, and local economic needs and interests.

We are requiring Dow to perform the investigations necessary to determine what cleanup alternatives are practical, however we have not reached the point to determine what those alternatives are. The MDEQ and MDCH are making progress in this area, and will continue to work with Dow Chemical to find the answers necessary to guide us toward a reasonable, scientifically-based plan that ensures the health and well-being of those affected by dioxin contamination.

Lone Tree/TRW Dioxin Update

Excerpts from this issue:

bullet The good the bad and the ugly
bulletMDEQ fills in data gaps
bulletSaginaw river floodplain soil not as contaminated as the Tittabawassee River flood plain
bulletSaginaw River sediment is highly contaminated
bullet Attractive Nuisance: Frankenlust Slurry pit and Dow boat docks
bullet The MDEQ, EPA, and US Fish and wildlife want to mitigate the proposed Frankenlust slurry pit as an  “attractive nuisance” because it is a hazard and  will expose wildlife to high levels of dioxin.
bullet What about the fishing docks being built by Dow Chemical ? Aren’t they an attractive nuisance for kids?
bullet Dow says dioxin only causes Chloracne
bullet Dr. Collins from Dow assures a young woman that  there was no problem with dioxin.
bulletMDEQ offers little response, Lone Tree had to do it for them.
bullet New Jersey,  dioxin  and the Passaic River ( We can dream)
bullet The NJ Department of Environmental Protection ( DEP) filed suit against Occidental Chemical to began the cleanup and dredging of the Passaic River which is contaminated with very high levels of dioxin. Levels that exceed 1million ppt in some areas.
bullet They want the river cleaned up to 17 ppt maximum level.
bullet

Why? Because it makes good economic sense and because clean healthy rivers attract people and add to the quality of life in our communities.

Dow Work Plans
bullet

If history repeats itself Dow will once again, with their army of consultants, PhD's, regulatory lawyers submit plans that will be deficient and create additional delays, tax resources at the state level and cost the taxpayers money.

bullet

It should come as no surprise that cursory review of the plans show Dow is attempting to do three  things: 
bulletRewrite the laws that regulate them
bulletDevelop the science they want (even if it takes years)
bulletDelay any semblance of real investigation

bullet
