QUAPAW HISTORY
 Dhegihan Sioux
 Same Siouan linguistic
family as Ponca, Osage,
Omaha and Kansa tribes.
 Early 1600s: Started

QUAPAW HISTORY
~48,000 acres
30,000,000 + acres

TRI-STATE MINING DISTRICT
 Began mining the area
during the late 1800’s,
lasted until approximately
1970
 Mining and milling of ore
(primarily lead and zinc)
produced more than 500
million tons of waste in area
 Two primary types of
wastes from mining
processes: chat (coarse
tailings) and fine tailings

 ~32,000,000,000 gallons of
water fill the mines today.
 26,000 acres contained within
Superfund Site boundary (OU4).
 ~ 2,800 residential yards

TAR CREEK SUPERFUND SITE
 Environmental problems
began showing up in 1979
with the advent of acid
mine drainage from the
underground mines
flowing into Tar Creek
through abandoned mine
shafts and boreholes
 1980 Tar Creek Task Force

TAR CREEK SUPERFUND SITE
 Designated as a Superfund
Site in 1983, following the
establishment of Hazard
Rank System and National
Priorities List in 1981 and
1982, respectively under the
Comprehensive
Environmental Response,
Compensation and Liability
Act (CERCLA).
 Four Main Objects of
Remediation

 Operable Units
 OU1 – Surface
Water/Groundwater
 OU2 – Residential
Properties
 OU4 – Chat Piles, Other
Mine and Mill Wastes,
Smelter Wastes
 OU5 – Sediment and
Surface Water

INITIAL INVOLVMENT AT TAR CREEK
 Through the EPA Region 6 General Assistance Program
(GAP), the Quapaw Tribe Environmental Office was
established on October 1, 1997.
 In June of 1998, the Quapaw Tribe Chairman and the EPA
Region 6 Administrator signed a Tribal Environmental
Agreement, which established a formal agreement
between the Tribe and EPA to address the issues raised
regarding the environmental protection of lands within the
Quapaw Tribe’s jurisdictional lands.
12
INITIAL INVOLVMENT AT TAR CREEK
 Currently, the Quapaw Tribe is administering an EPA
Superfund management assistance grant under an existing
Superfund support agency cooperative agreement.
 The tribe entered into this support agency cooperative
agreement with EPA in 2001.
 This management assistance grant has enabled the tribe to
have “meaningful and substantial involvement” in the
decisions related to the development and implementation
of remedial activities.
13
INITIAL INVOLVMENT AT TAR CREEK
 Working together with EPA and other stakeholders on Tar
Creek issues over the past 12 years has enabled the
Quapaw Tribe Environmental Office to develop the
technical capacity required to administer a remedial
response cooperative agreement.
 Consequently, in 2013, the Tribe negotiated a remedial
response cooperative agreement with EPA Region 6 to
self-perform the remediation of an historic and culturally
significant tribal property know to the Quapaw as the
“Catholic 40.”

INITIAL INVOLVMENT AT TAR CREEK
 Cooperative Agreement for Remedial Action signed
between EPA and the Quapaw Tribe of Oklahoma was
the first-ever Remedial Action in the nation
conducted by a tribe on property that they own.
 On-the-ground remedial activities would be
completed by Quapaw Tribe’s construction division,
Quapaw Services Authority (QSA).

SE Distal Zone, Distal 8
“Catholic 40”
Tribal Trust Land
40-acre parcel owned by the
Quapaw Tribe of Oklahoma and was
set aside in 1892 to the Catholic
Church for religious and education
purposes. In that same year, St.
Mary’s of the Quapaw, a Catholic
Church, a cemetery, and a boarding
school was established.
 St. Mary’s operated up until 1927,
following abandonment, the church
leased the property for mining in
1937.
 In 1975, the Catholic Church deeded
the property back to the Quapaw
Tribe of Oklahoma.
