1 am writing to request additional information from the Environmental Protection Agency (EPA) 

regarding dioxin and dioxin exposure, prior to providing my comments during the public 

comment period on the agency's recently released interim preliminary remediation goals (PRGs) 

for cleanup of dioxins in soil. 

1 . Has EPA, or any other federal agency, conducted an economic analysis to determine the 

financial impact of implementing the interim PRIG? If so, please outline the costs to 

private and public entities, the expected impact on jobs, and commercial and residential 

property values. 

2. What was the impetus to issue PRGs by the end of 2009? Similarly, why have you 

selected the end of 2010 as the date by which a complete dioxin reassessment is to be 

completed? 

3 . 1-low many sites are currently on EPA's National Priorities List (NPL) for dioxin 

contamination? How many sites would be added if this interim PRIG is adopted? 

4 . How many sites currently have dioxin contamination that is classified under the 

Superfund Alternative (Site Listing) Approach? How many additional sites would EPA 

expect to pursue under this approach if the interim PRG is adopted? 

5. What are the dioxin toxicity equivalent (TEQ concentrations in NPL and Superfund 

Alternative sites that have been identified as having dioxin contamination? 

6. How many households are within NPL and Superfund Alternative sites that have been 

identified as having dioxin contamination? What is the total population of these 

locations? How would this change under the new PRG? 

7. Given that the dioxin contamination in Tittabawassee River/Saginaw River and Bay 

Contamination Site and within the City of Midland are not listed in the EPA's database 

as either on the NPi. or through the Superfund Alternative Approach, how will you 

accurately estimate the effect on the new PRIG on the nation and its citizens?

8 . How many residential sites have received cleanup decisions for dioxin contamination? 

Will EPA be reviewing those sites that have received cleanup decisions in lieu of new 

interim or final PRGs? 

9. Under Michigan state law, residential properties that have dioxin contamination would 

be labeled as "facilities" (Part 201 of Michigan state cleanup law) . How many 

residences within the Tittabawassee River/Saginaw River and Bay Contamination Site 

and the City of Midland would be labeled as toxic facilities based upon you the new 

interim PRG? What are the economic consequences regarding such a finding to both 

property owners and the local municipalities? What is the appeal process for a property 

owner and what would their disclosure obligations be as a result of this finding? 

10. Upon the issuance of EPA's final dioxin reassessment and final PRGs by the end of 

2010, does the EPA anticipate to re-evaluate cleanup decisions made with the interim 

PRGs simultaneous with the release of the final PRGs, or after the release? How many 

sites does EPA anticipate to re-evaluate? If done after the release of the final PRGs, 

when does EPA anticipate finalizing those re-evaluations? 

11 . Which studies, if any, studied how and to what extent soil dioxins are absorbed into the 

human body? Did any of those studies specifically examine the health risks associated . 

with exposure to soil dioxins'? 

12. How does lowering the soil criteria reconcile with EPA's own assertion that contact with 

contaminated soil is only 1 % of a person's total exposure? "EPA's Review of the 

University of Michigan Dioxin Exposure Study, Page 8." 

13 . How has the EPA worked with Agency for Toxic Substances and Disease Registry 

(ATSDR) in determining this new level? If so, what was ATSDR's involvement and 

contributions? Has ATSDR agreed that this interim PRG level is appropriate to 

safeguard public health? 

I respectfully request that you respond to these questions in writing by February 1, 2010. Please 

do not hesitate to contact me, or Brian Sutter of my staff, at 202-225-3561 should you need 

further clarification . Thank you for your timely attention to this matter .
