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):
 | Filling out and returning the "Residential
Property Use Activity" document is entirely voluntary according to the MDEQ.
 | If you decide to complete and return the
document to AKT Peerless, consider adding the language mentioned the the
lawyers letter. |
|
 | The "License Agreement" must be completed to
be eligible for Priority 2 mitigation measures.
 | If you decide to sign and return,
consider adding the language mentioned the the lawyers letter. |
|
 | If 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. |
 | If you have any questions, contact Sherry
Berry at 816-714-7100 or Tara Inzerillo at 816-474-8100. |

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.

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.
Tittabawassee 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:

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:
 | Annette 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. |
 | When 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. |
 | Not 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. |
 | Do NOT assume AKT Peerless will swoop in and take care of everything
without your participation. |
 | AKT 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. |
 | Before meeting with AKT Peerless, do the following:
 | Based 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. |
|
 | If you do not do the following, it's unlikely anything you ask for will
be done properly:
 | Point out the problem areas to the P-2 manager |
 | Document problem areas with the P-2 manager. |
 | Re-explain the problems in minute detail (show them your documents)
to all work crews that show up. Every time!! |
 | Supervise the work is completed to your satisfaction. |
 | Call the P-2 manager back as often as it takes to get things right. |
 | The 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 |
 | If 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). |
|
 | Be prepared for the following:
 | Work 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. |
 | If 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) ...". |
 | Observe 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. |
 | Most 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). |
 | Do 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). |
 | Take a controlling stance, instead of just getting out of their way
& expecting the work crews to know what to do. |
 | Take before and after pictures. |
|
 | The "License Agreement" included in the packet must be completed to be
considered for any P-2 IRA work.
 | The agreement authorizes Dow to access your property for the
purposes of conducting soil sampling and survey work. |
 | The 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". |
 | This is a legal document, you may want your lawyer to review, so do
it now. |
|
 | To be considered for P-2 IRA, you must complete the enclosed
"Residential Property Use Activity Survey" or "Agricultural Property Use
Activity Survey".
 | The State officials contributed to the design of the form but
indicate they are not really sure how the information will be used by
Dow. |
 | Many 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? |
 | Any 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. |

Lone Tree/TRW Dioxin Update
 | Dow Notice of Deficiency
 |
Dow has 60 days
from March 2nd to resubmit work plans to correct the
26 deficiencies
noted |
|
 | Midland Daily News editorial
 |
The government
seems to be asking The Dow Chemical Co. if it is serious about
addressing local dioxin contamination. |
|
 | Shame on you Mr. Musser
|
 | Dow Remedial Investigation Work
Plans for the Saginaw River NOT submitted
 |
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”. |
|
 | Dow blow's their own horn, We
can't hear you Mr. Liveris
 |
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. |
|
 | March 15th deadline for public
comment on Dow RIWP
 |
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. |

New video documentary: "Mr. Damore goes to Lansing" now on-line
Paul Damore, a Grand
Valley State University student and resident of the Tittabawassee River
flood plain, has created a short "opinion" documentary that is now being screened in a
number of film festivals in the Grand Rapids area. The film
covers Paul's 2005 journey to Lansing in attempt to

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:
 |
Major Items and Issues for the Tittabawassee
River and Midland RIWPs (TR RIWP and Midland RIWP)
 |
The RIWP must contain a single
comprehensive schedule that consolidates the major work activities
proposed by the RIWP and associated studies. |
 |
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. |
 |
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. |
 |
The RIWP does not address comments
previously provided to Dow on the PCOI identification process. |
 |
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. |
 |
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:
 |
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. |
 |
The processes and equations upon
which the model is built. |
 |
The process by which the model will
be calibrated to the n samples. |
 |
Verification of the model by
demonstrating that it also matches existing data. |
|
 |
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 |
 |
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. |
 |
The RIWP needs to specifically include
mapping and sampling of erosional areas (e.g. cut banks). |
 |
The Midland PCOI investigation strategy
needs to be reevaluated as indicated by U.S. EPA. |
 |
DQOs These will need to be revised
to reflect required modifications to the RIWPs. |
|
 |
Major Items and Issues for the Human Health
Risk Assessment Work Plans (HHRA WP)
 |
Review and approval process for
components of the HHRA WP. |
 |
Preliminary Conceptual Site Model (PCSM) |
 |
Identification of Exposure Pathways |
 |
Exposure Data Collection |
 |
Exposure Inputs to HHRA Equations |
 |
Toxicity values |
 |
Toxic Equivalency Factors (TEFs) |
 |
Screening Level Risk Assessment (SLRA) |
 |
Forward-looking Probabilistic Risk
Assessment |
 |
Area Wide Cleanup Criteria (AWCC) and
Site Specific Cleanup Criteria (SSCC) |
 |
Soil and Sediment Concentrations related
to food-chain pathways |
 |
Identification of other PCOIs |
 |
Citations and/or references need to be
included for all applicable Part 201 regulatory requirements or EPA
guidance |
 |
Sequence of proposed HHRA WP components |
 |
A review and approval process for the
individual workplan for each component of the HHRA work plan is
necessary. |
 |
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:
 |
Ignore compliance with their
license
|
 |
Delay defining the extent of
their contamination
|
 |
Deny the toxicity of dioxin
|
 |
Rewrite the science to benefit
them
|
 |
Rewrite the laws that govern
them
|
 |
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:
 |
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. |
 |
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. |
 |
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. |
 |
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. |
 |
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. |
 |
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. |
 |
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. |
 |
Dow’s proposal for three surface water sample locations in
the TR to be sampled during a base flow and flood event is
inadequate. |
 |
EPA requests that MDEQ require Dow to undertake the
following four sequential steps in order to properly characterize the TR and
Floodplain:
-
Completion of a thorough PCOI study (Principle
Contaminants of Interest)
-
Completion of a thorough geochemical study on all of the
identified PCOIs (or all PCOI chemical groupings)
of interest
-
Completion of a pilot characterization study to
determine horizontal sampling grid interval for both the River
sediments and the floodplain soils
 |
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). |
 |
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. |
Completion of a full characterization study including
the preparation of depth-based contaminant-concentration contour maps
for all identified PCOIs
|
 |
EPA recommends that, at a minimum, the final work products
of the T-RIWP characterization process include the following:
 |
90 ppt TEQ boundary line map (vertical and horizontal). |
 |
Depth based concentration
contour maps with a 100 ppt TEQ contour line.
 |
0-6 inch surface TEQ
concentration contour map. |
 |
TEQ concentration contour
maps for all underlying 1-foot vertical compositing intervals |
|
 |
Comparable boundary lines and
maps should be produced for all other PCOIs. |
|
 |
Dow’s proposal in the M-RIWP to delay Phase II sampling
until 2008 is not acceptable to EPA. |
 |
... 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. |
 |
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. |
 |
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.
 |
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. |
 |
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. |
 |
Dow's proposal, in the HHRAWPs, to use probabilistic
methods for deriving dose-response parameters for the PCOIs is
unacceptable.
 |
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.
 |
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. |
|
|
|

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.

Quality.

Excerpts
from this issue:
 |
The good the bad and the ugly
 | MDEQ fills in data
gaps |
 | Saginaw river
floodplain soil not as contaminated as the Tittabawassee River
flood plain |
 | Saginaw River
sediment is highly contaminated |

Attractive Nuisance: Frankenlust Slurry pit and Dow boat docks
 |
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. |
 |
What about the fishing docks being built by Dow Chemical ? Aren’t
they an attractive nuisance for
kids? |
|
 |
Dow says dioxin only causes Chloracne
 |
Dr. Collins from Dow assures a young woman that there was no
problem with dioxin. |
 | MDEQ offers little response,
Lone Tree had to do it for them. |
|
 |
New Jersey, dioxin and the Passaic River ( We can dream)

 |
Dow Work Plans
 |
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. |
 |
It should come as no surprise that cursory review of the plans show
Dow is attempting to do three things:
 | Rewrite the laws that regulate them |
 | Develop the science they want (even if it takes years)
|
 | Delay any semblance of real investigation |
|
