A. Summary of Proposed Changes
An extension of the Project Closing Date (from November 27, 2015, to September 27, 2016) is proposed to
enable the completion of four key activities: (i) Malargüe uranium remediation works; (ii) creation of a
public green space in Malargüe; (iii) final deployment of the Environmental Monitoring Management
System Tool (SIGA); and (iv) development of an environmental strengthening plan for provincial
authorities. These activities are key to the satisfactory achievement of the PDO and meeting the overall
project targets.
An adjustment to the results matrix is also proposed in order to make some indicators more specific and
measurable, and to better monitor the progress and results achieved during the remaining Project’s lifespan.

B. Project Status
The Board approved this Project on July 31, 2008, and it became effective on April 28, 2010. At Mid-term
review of the Project (December 2012), disbursement was around 12%. Disbursement to date from the
US$30 million Loan is US$23.14 (or 77% of the total Loan amount).

                                                                                                           5
In August 2015, the Borrower and the Bank agreed to a short-term action plan to improve the
implementation progress of the Project. To date, the National Nuclear Energy Commission (CNEA) has
accomplished most of the actions agreed in this action plan, achieving the following results:

       Acceleration of the remediation works in Malargüe, which aims to contain permanently -in an
        engineered construction cell- a total of 700,000 tons of uranium contaminated tailings from the
        closed Malargüe processing plant (global progress of civil works is now 80%).
       Complete transportation of the total volume of contaminated tailings to the Malargüe remediation
        site; thereby reducing pollution and economic and public health risks for the surrounding
        communities.
       Complete the environmental studies of five uranium legacy sites (old uranium mines and uranium
        processing facilities) located in five provinces in the country.
       Resolution of the national budgetary credit line for the project
       Presentation of the pending External Financial Audit, with no major issues to report.
       Development and installation of an Environmental Monitoring Management System Tool (SIGA) in
        CNEA almost complete.
       Remediation plans for the “El Chichón" and “Los Gigantes�? sites agreed between CNEA and the
        local and provincial governments, based on the Malargüe 'best-practice' example.

As a result of the significant progress made by CNEA in the implementation of the agreed action plan, the
progress toward achieving the PDO and the Implementation Progress (IP) were both rated as Moderately
Satisfactory, after the mission undertaken in October, 2015. With the proposed extension of the Closing
Date, the PDO remains relevant, strategic, and achievable.

ENVIRONMENTAL BASELINE OF THE OTHER SEVEN SITES. The project has concluded
environmental and radiological baseline studies of seven other uranium legacy sites: El Chichón, Los
Gigantes, Tonco, Pichiñán, La Estela, Los Colorados, and Huemul. The results of these studies will
contribute in the identification of the most appropriate alternative for the future remediation of these sites
and for the preparation of the environmental impact assessments.

SAFEGUARDS. The Project's safeguard performance has ranged from satisfactory to moderately
satisfactory throughout the last two years of implementation. CNEA has developed the remediation works in
Malargüe according to the agreed Environmental Management Plan (EMP), maintains a team that on a daily
basis supervises the contractor and implements a very detailed Monitoring Program that measures
radiological, environmental, health and safety parameters at the remediation site. Additionally, the Project
maintains close monitoring of several sites around Malargüe to reduce risks to the local community and
workers.

The local and provincial governments as well as the National Nuclear Regulatory Authority (ARN) of
Argentina have supervised the remediation works in Malargüe. Consultations and communication with the
local government and communities were performed in a satisfactory manner and have continue during
Project implementation. Access to information related to environmental monitoring has been limited, but
CNEA has presented the Bank with a plan to improve it; thus access to information is expected to show
improvement once the SIGA is completed. The Environmental Impact Assessment for the Malargüe works
is published in the web site of CNEA.

As of today, there are no Indigenous Peoples in the Project sites, no resettlement nor any other safeguards
issues related to the Project.

COMMUNICATION STRATEGY. CNEA has implemented a communication plan involving local

                                                                                                                 6
authorities and civil society since the beginning of the project. In Malargüe, workshops, technical fora, site
visits, and inspections have been performed together with the local government, universities, agricultural
agencies, high schools, and members of the surrounding communities. At the El Chichón, a focused strategy
with the municipality, provincial government, and universities using the Malargüe works as an example,
facilitated the remediation agreement for this site.

INTERNATIONAL ADVISORY PANEL. The establishment of an international advisory panel, as foreseen
in the Project Appraisal Document did not materialize due to a variety of issues such as governmental
regulations limiting the hiring of international consultants. As an alternative, CNEA has confirmed the
formation of this panel with the participation of two international experts in nuclear remediation from the
International Atomic Energy Agency (IAEA) and a national expert to review the remediation works in
Malargüe, the proposed remediation plan of El Chichón and Los Gigantes and to participate in a high level
uranium-remediation training in Malargüe, with the involvement of governmental and provincial agencies.

The input and participation of this panel in these activities will contribute in the strengthening of the
Government of Argentina's capacity to assess and mitigate environmental risks associated with closed
uranium mines and other related legacy sites, in accordance with international good practice which is an
important aspect of the PDO of the Project.

C. Proposed Changes

                                    Development Objectives/Results
Project Development Objectives
Original PDO
The development objectives of the project are to: (a) strengthen Government of Argentina's capacity to
assess and mitigate environmental risks associated with closed uranium mines, processing sites, and related
mining sector investments in accordance with international good practice; and (b) reduce potential economic
and health damages associated with a closed uranium mining site in Malargüe, Mendoza.
Change in Project's Development Objectives
Change in Results Framework
Explanation:
Some of the current indicators are difficult to track and measure because they include merged parameters
(environmental impact assessments studies, design, remediation plans, communication plans, etc.) for
different sites with different environmental conditions which are located in six different provinces, instead
of specific site and the related investments. Therefore, a revision of the indicators is proposed in Annex 1,
to better reflect the expected outcomes of the project and actual progress made towards the PDO.

The four indicators for the PDO are being revised and a new one is added.
Indicator 1. Sites separated into two indicators (1 and 2) to better measure results and investments.
Indicator 3. Rephrased to measure the number of CNEA labs accredited with the ISO 17025.
Indicator 4. Rephrased to address the reduction of health, environmental and economic risks through the
removal and containment of the tailings.
Indicator 5. Rephrased to measure the number of governmental agencies that will be trained by the Project

Out of 10 Intermediate Indicators, five are being revised. The updated indicators will be included in the
Project Operations Manual to comply with the provisions of the Loan Agreement.

Change in Loan Closing Date(s)
Explanation:
On October 22, 2015, the Government of Argentina (GoA) made the formal request for a 10-month
extension of the current Closing Date. The extension of the Closing Date (from November 27, 2015, to
September 27, 2016) will allow the project to be completed successfully and the PDO to be achieved
through the completion of the uranium Malargüe Remediation works, the first uranium remediation in the
country and probably in Latin America. The extension will also afford additional time needed to complete
the following:

(i)     the creation of a public (green) space in Malargüe;
(ii)    the final deployment of the Environmental Monitoring Management System Tool (SIGA);
(iii)   the institutional strengthening plan for provincial authorities.

These activities are key to the satisfactory achievement of the PDO and meeting the overall project targets,
thus ensuring that all environmental and human health risks are permanently addressed, per the agreed
international standards.

REMEDIATION WORKS. The extension of the current Closing Date will make it possible to: i) complete
the removal and transportation of contaminated soils to the remediation site and iii) build the final layer to
close the encapsulation cell. CNEA has estimated that the additional time needed to complete these works is
seven months. Climatic conditions have in the past seriously affected the speed of the remediation works;
thus a 3-month period is added as a precautionary measure to the proposed deadline.

Given the health, social, and economic risks associated with uranium-contaminated sites, the Project is
politically sensitive and carries a high reputational risk for both the Government of Argentina (GoA) and the
Bank, if the remediation works were not to be completed. The Government of Argentina and CNEA plan to
use this Project as a demonstration for future remediation works of the other seven uranium legacy sites in
the country.

PUBLIC GREEN SPACE IN MALARGÜE. As part of the mitigation measures of the legacy site, the
municipality and CNEA agreed to build a public green space in Malargüe (in a non-contaminated area)
based on a design to be proposed by local citizens. The estimated time required to complete the bidding and
construction of the park is seven months.

ENVIRONMENTAL MONITORING SYSTEM TOOL. The completion of the SIGA is estimated to take
four months. The activities to be undertaken are: i) complete testing of the system, ii) provide training to
CNEA staff, iii) complete the public portal and iv) install a Business intelligence module.

INSTITUTIONAL STRENGTHENING PLAN FOR THE PROVINCIAL GOVERNMENTS. CNEA has
prepared and proposed an Environmental Strengthening Provincial Plan which was consulted and agreed
with the governmental agencies where the uranium legacy sites are located. The estimated time required to
complete the implementation of the plan is about eight months.
