Remedial Action

The OU4 remedy addresses the source materials, rural
residential yard contamination, transition zone soil
contamination, and contamination in water drawn
from rural residential wells. The remedy also includes
chat sales and relocation, which will continue to be
implemented by the Lead Impacted Communities Re-
location Assistance Trust. EPA will assist chat sales
participants as part of EPA's CERCLA remedy. EPA
does not own any chat and will not purchase any chat.

The cleanup will be conducted in phases as EPA ob-
tains signed access agreements and documents re-
quired to perform the work. The first phase will
address mine and mill waste that is located in distal
areas. Distal areas are outside of the core area of
Picher and Cardin. This approach will allow chat
sales that are occurring within the core area of the site
to continue. It is EPA's intent to remove the waste to
reduce its footprint on the property and enable prop-
erty owners to maximize the use of their land.

Several contracts were awarded in December 2009.
These contracts will construct a part of the repository
(i.e. the location where mine and mill waste will be
disposed), and clean up the contaminated soil in rural
residential properties, smelter waste, and move unre-
stricted chat in distal areas. Site activities will start in
January 2010.

Sampling Efforts

Access agreements must be received from the owners
of property that have source materials for EPA to
clean up source materials. There are two types of ac-
cess agreements for unrestricted property, Consent
for Entry and Access to Property and a Settlement
Agreement and Release.

The Consent for Entry and Access to Property

gives EPA permission to enter properties and to eva-
luate the amount and condition of chat deposits, other
mine and mill waste, and surface soil through sam-
pling. If needed, EPA may also install a temporary
haul road to perform the remediation (to be removed
afterwards), and remove the chat, mine and mill
waste, and contaminated soil for further disposition.

The Settlement Agreement and Release give EPA
permission to remove the chat and dispose of it. The
actions that EPA performs to excavate, transport, and
dispose of the chat are consi dered adequate compen-
sation for any value the chat may have.

For restricted properties, the Consent for Entry and
Access to Property to Sample gives EPA permission

to enter restricted properties and to evaluate the
amount and condition of restricted chat deposits, oth-
er mine and mill waste, and surface soil through sam-
pling.

EPA will work with chat owners and the Department
of the Interior and its agencies on plans to help facili-
tate chat sales. This includes but is not limited to find-
ing locations to stage the chat for future sales (with
appropriate tracking and security measures), and fa-
cilitating chat sales.

Without these signed documents, the implementation
of the remedial action will be delayed.

Community Participation

The EPA, in coordination with the Oklahoma De-
partment of Environmental Quality, and the Quapaw
Tribe has kept the community, public, governmental
entities, citizen advisory groups and interested parties
informed of Superfund response actions, and involved
these groups in planning. EPA would like to maintain
this effort and encourages residents and interested
parties to participate in meetings. EPA also encour-
ages individuals to contact our toll free number with
suggestions and ideas that can help the implementa-
tion of the remedial action to be successful. Informa-
tion on how you can get involved is available in the
"For More Information "section. Your participation
can make a difference.

Site Background

The Tar Creek Superfund Site is a former lead and
zinc mining area located in the northern portion of
Ottawa County, Oklahoma. The Site is part of the Tri-
State Mining District located at the junction of Okla-
homa, Kansas, and Missouri. The Site occupies ap-
proximately 40 square miles consisting of the Ottawa
County, Oklahoma, portion of the Picher Field mining
region and any area where a hazardous substance
from mining or milling in Ottawa County has been
stored or disposed. The Site is bounded by the State
of Kansas to the north. The major communities in-
clude Cardin, Commerce, North Miami, Picher, and
Quapaw.

The EPA is the lead agency and ODEQ is the support
agency for Operable Unit 4. Some of the Potentially
Responsible Parties (PRPs) identified for the Site par-
ticipated in the Remedial Investigation and Feasibility
Study for Operable Unit 4. EPA performed the hu-

man health and ecological risk assessments at the Site
and completed the Feasibility Study.

Frequently Asked Questions

Why are there two access agreements to sign?

The document named "Consent
for Entry and Access to Prop-
erty" grants EPA access to
evaluate, sample, and remove
chat. The Consent for Entry
signed, will allow EPA to
evaluate marketability of the
chat and facilitate communica-
tion between the property owner
buyers.

The document named "Settlement Agreement and
Release" grants EPA the right to remove the chat. The
chat will be removed, and unmarketable chat will be
properly disposed either in depressed features located
in distal areas or taken to a central repository for dis-
posal.

Will signing the consent for entry and/or settlement
agreement at this time prevent the property owner
from selling the chat independently before EPA be-
gins work on the property?

No. The property owner is welcome to sell its chat at
any time in accordance with the "Chat Rule." If the
property owner sells some or all of his chat before the
remediation work begins, EPA will address only the
chat or contaminated soil that remains, if any.

Will signing the access agreement or settlement
agreement "lock-in " the property owner such that
the property can't be sold until the work is com-
plete?

No. The access agreement does not bind the owner to
the property until work is completed. The owner can
sell the property at any time and EPA will work with
the new property owner to obtain access agreements.

Is the access agreement binding on someone that
might want to buy the property before the work is
completed?

No. If the property is sold, the access agreement be-
tween EPA and the property seller expires. EPA will
work to obtain new access agreements from the buyer
before proceeding with chat remediation.

Legal Considerations

If waste material is used in a way that creates a threat
to human health or the environment, the owner of the
property and the party responsible for creating the
hazardous situation could be liable for a cleanup un-
der the CERCLA law. Because these mine wastes of-
ten contain lead, cadmium, zinc or other metal
contaminants at levels that could cause harm to both
human health and the environment. Using them in
situations that would allow people, animals, plants, or
fish, etc. to come into contact with the material could
cause harm that need clean up action under CERCLA.
To avoid potential CERCLA liability, EPA generally
recommends that property owners, haulers, operators,
and individuals or businesses that sell, buy, or use
mine waste materials which contain hazardous mate-
rials, use the materials in a manner that prevents ex-
posure to humans and other receptors that would not
cause harm to the environment.
