RE: Request for Data
Dear Counsel:

On November 15, 2016, the US. Environmental Protection Agency (EPA) was provided a copy of a
Petition ?led by you on behalf of your clients, Michael and Robbin Dailey. This Petition contains certain
allegations regarding radioactive contamination at the Dailey?s property, some of which include the
following:

0 Paragraph 7: ?Dusts inside the Dailey Home were shown to contain radioactive Th?230 at levels
at least two hundred times higher than Background levels. . 

0 Paragraph 12: ?Plaintiffs ?rst learned that the Dailey Property was contaminated with
radioactive material in 2016.?

0 Paragraph 90: ?The Dailey Property is contaminated by radioactive material."

0 Paragraph 91: ?Samples taken on and around the Dailey Property con?rm a highly elevated
presence of radioactive particles in the soil and dust.?

0 Paragraph 92: ?Dust samples from inside the Dailey Home contain decay products of
radioactive isotopes U-238 .. 

We have also received your November 16, 2016 letter to EPA Region 7 Regional Administrator Mark
Hague providing the December 2015 published journal article, map and summary data table. As a
public health agency, EPA takes very seriously any information that relates to the actual or potential
exposure to hazardous substances, pollutants or contaminants. EPA notes that the samples identi?ed in
the summary table were collected in July 2016, but this information is only now being provided to EPA

several months later.

Out of an abundance of caution, EPA is developing a plan for sampling of dusts and soils at the Dailey
home and other areas in Bridgeton. In order for us to develop a scienti?cally sound plan, as well as fully
assess the potential for unacceptable exposure to radioactive contaminants, EPA needs the relevant data
that you have. We ask that you immediately provide the soil and dust data not just from the Dailey
residence associated with the allegations referenced by you in the Petition, but also any other similar
data you possess from nearby residences, businesses and publicly accessible locations in that area. EPA
will utilize this data to inform the development of a sampling plan.

Speci?cally, EPA requests all laboratory data, laboratory reports, and any Quality Assurance Project
Plan or other written procedures that describe how the samples were collected, analyzed and validated.
Further, EPA asks that you provide documentation identifying the speci?c locations where samples were
collected. Once EPA has an opportunity to review this data and methods employed to collect and
analyze these samples our Agency will determine the appropriate next steps.

EPA continues to emphasize that our Agency will evaluate all scienti?cally valid data, and we greatly
appreciate your expedited attention in providing this information. We understand that the allegations in
the Petition have caused great concern for your client and others in the Bridgeton community, and we
take these concerns seriously. Please do not hesitate to contact me at (913) 551-7826 if you have any
questions.

Sincerely,

 
Alyse Sioy, 
Associate Deputy Regional Counsel
