Objectives and Strategies for Amending
the 2014-2018 Five Year Plan to Address
Impacts of Uranium Contamination from
Tronox Navajo Area Uranium Mines
INTRODUCTION
On January 21, 2015, the Tronox settle-
ment agreement resolving fraudulent
conveyance claims against Kerr-McGee
Corporation and related subsidiaries of
Anadarko Petroleum Corporation went
into effect. Pursuant to the settlement
agreement, Anadarko paid $5.15 billion
plus interest to the litigation trust on
January 23, 2015, of which, U.S. EPA
received approximately $1 billion to fund
cleanups at over 50 abandoned uranium
mines in and around the Navajo Nation.
In addition, Navajo Nation received
directly approximately $45 million from
the settlement, http://www2.epa.gov/

PURPOSE
In January 2013, EPA, the Bureau of Indian Affairs, the Nuclear
Regulatory Commission, the Department of Energy, the Indian Health
Service, and the Agency for Toxic Substances and Disease Registry,
in consultation with the Navajo Nation, completed a five-year effort
to address uranium contamination in the Navajo Nation. The effort
focused on the most imminent risks to people living on the Navajo
Nation. While the last five years represent a significant start in
addressing the legacy of uranium mining, much work remains and
the same federal agencies have collaborated to issue a second Five
Year Plan http://www3.epa.gov/region9/superfund/navajo-nation/
pdf/nn-five-vear-plan-2014.pdf. The purpose of the second Five-Year
Plan is to build on the work of the first plan, make adjustments based
on information gained during this period, and plan the next steps in
addressing the most significant risks to human health and the environ-
ment.
As a result of the Tronox/Kerr McGee settlement, the second Five-Year
Plan (2014-2018) is being amended to address impacts of uranium
contamination from Tronox Navajo Area Uranium Mines.
OBJECTIVES
The objectives of the 2014-2018 Five-Year Plan Tronox addendum are designed to comprehensively assess and cleanup,
contamination related to Tronox legacy uranium mining and milling activities on and impacting the Navajo Nation.
The objectives are:
Objective 1: Assess Water Supply Sources for Contamination in the Cove Watershed
and San Mateo Creek Basin
The goal is to assess water supply sources and build conceptual site models by 2018 that can be used as a tool to under-
stand impacts of legacy uranium mining and milling in the soils and groundwater systems and to identify the current
and potential future risks to human health.

Objective 2: Assess and
Cleanup Tronox Uranium
Mine Sites
During the next five years, the EPA
will conduct a series of assessments
and engineering evaluation/cost
analyses at uranium mine sites for
the purpose of obtaining necessary
information to develop an appropri-
ate number of investigations which
will be become the basis for any
subsequent actions that may be
necessary to reduce the threats to
human health and the environment
posed by these 49 mine sites.
Objective 3: Assess and
Cleanup of Quivira North-
east Churchrock Legacy
Uranium Mine Sites
During the next five years, the EPA
will complete the assessments and
engineering evaluation/cost analy-
ses at the two Quivira Northeast
Churckrock uranium mine sites. EPA
will release the engineering evaluation/
cost analysis for public comment and
hold public meetings for the purpose
of getting community input prior to
selecting a final action to reduce the
threats to human health and the envi-
ronment posed by these mine sites.
Objective 4: Communicate
and Coordinate with Com-
munities
The goal for the 2015 Five-Year Plan
partners is to provide clear and under-
standable information about ongoing
and planned actions and activities in
the Grants Mining District. This will
be accomplished through enhanced
coordination amongst the partners
to provide clear and understandable
information that the community
members request, want, and/or need.
Objective 5: Provide
Job Opportunities and
Work Force Development
throughout the Navajo
Communities
The implementation of the Tronox/
Kerr McGee settlement at various
sites has identified the need for addi-
tional resources and attention to job
training and workforce development
for Navajo businesses and commu-
nity members. The goal is to provide
opportunity and development to
Navajo businesses and community
members through Grants, Contracts,
and Interagency Agreements.
