Conservation issues presented to the World Heritage Committee in 2012
The State Party submitted a succinct report on 29 March 2012 that provides an update on actions implemented in response to Decision 35 COM 7B.120.
The final report of the geophysical study was received by the World Heritage Centre on 28 March 2012 and contained a report dated 30 January 2012 from the Corporacion Minera de Bolivia (COMIBOL).
a) Implementation of emergency measures identified by the 2011 Technical Mission
The State Party reports that the following emergency measures were takenin relation to the geotechnical and stabilization studies for the CerroRicoMountain:
i) The report of the first phase of the geophysical and stabilization study of the CerroRicoMountain undertaken by the Ministry of Mining and Metallurgy, dated 12 August 2011, was submitted by the State Party. It includes the mapping of cavities found in the mountain and the geotechnical and stabilization study (Phase I) prepared by SERGEOTECMIN, a decentralized entity of the Ministry. The recommendations made by the study include: (i) the necessity to complete as a matter of urgency, the measurements of galleries in order to dispose of updated data and exact coordinates of the location of the mine entries and their dimensions; (ii) the urgent need for a detailed topography of the mountain which will allow the localization of the mine entries and other specificities which are affecting the mountain, as a tool for monitoring; (iii) the need to sensitize the miners to ensure that they use modern technology in the design of galleries, blasting systems and extraction, systems of extraction of minerals and sewage systems.
The study concludes that only when adequate and precise topography and measurements are available can the second phase of the geotechnical and stabilization study of Cerro Rico commence.
ii) Creation of the Emergency Committee for the Safety of the CerroRicoMountain in December 2011, which includes representatives from the following Ministries: Cultures, Mining and Metallurgy, Environment and Water, Presidency and Foreign Affairs. The report states that this entity is still evaluating the various Ministry reports for the development of a Strategic Emergency Plan for Cerro Rico. No information was provided on the terms of reference for the operation of the Emergency Committee; however, it has held six meetings and produced two reports which were submitted to the World Heritage Centre;
iii) Signing of an agreement with the Manquiri Mining Enterprise by the Ministry of Cultures which will allow work on the consolidation and protection of the top of the mountain and the conservation of old mine remains for future tourism activities;
iv) Presentation of a project by the Corporacion Minera de Bolivia (COMIBOL) for the consolidation and protection of the top of the mountain; this project will have a cost of USD 2,700,000 and will be supported by the local government and COMIBOL. No further details or a proposed course of action were provided for this project. The report also states that the Ministry of Mining and Metallurgy will be involved in the development of projects for the consolidation of the mountain;
v) A report dated 30 January 2012 presented by the Regional Director of COMIBOL on the suspension of exploitation works on the mountain was also submitted. In this report, it is also stated that based on the recommendations made by the geophysical study, legal measures have been taken against illegal mining activity at the property. No information was presented on amendments to Supreme Decree 27787 or on the monitoring system to assess conditions of stability.
b) Development of a participatory Management Plan for the property and the official submission of the buffer zone
The State Party reports that a seminar will be held in April 2012 to initiate a process for the development of the Management Plan for the property and also for the delimitation of a new buffer zone. The seminar will also evaluate the work of the Emergency Committee for the Safety of Cerro Rico, as well as the various tourism projects to be developed by private entities. As for the delimitation of boundaries for the property and the buffer zone, this is expected to be submitted within the Retrospective Inventory process of the Periodic Reporting exercise of the Latin America and the Caribbean region.
Analysis and Conclusions of the World Heritage Centre, ICOMOS and ICCROM
The World Heritage Centre and the Advisory Bodies note the establishment of the Emergency Committee for the Safety of the Cerro Rico, as well as the plans for the development of a Strategic Emergency Plan for the property. They would also encourage the involvement of stakeholders and representatives from non-governmental organisations concerned with the protection of the CerroRicoMountain and the City of Potosi.
They note the completion of the geophysical study and consider its recommendations important in further identifying the anomalies affecting Cerro Rico, and also in undertaking a more complete analysis. In particular, the study recommended performing or conducting seismic refraction profiles in the mines directly on ceilings or floors of the galleries to check the speed values and if possible, drilling exploratory wells to verify the physical characteristics of the resistivity and seismic anomalies of the mountain, and based on the collected information, creating a three dimensional model covering the entire Cerro Rico in the range of elevations studied.
They note the various projects planned to ensure the consolidation and structural stability of the mountain, and also the legal measures put in place to halt illegal extraction, but note that there is no updated information on the changes to Article 6 of Supreme Decree 27787. They also note that no information was provided on the undertaking of a comprehensive topographic study and the installation of a monitoring system to assess the stability of the mountain at monthly intervals.
The World Heritage Centre and the Advisory Bodies note the progress made in addressing the unstable and dangerous conditions of CerroRicoMountain, but wish to highlight to the Committee that further information is needed on how the recommendations of the geophysical study will be implemented and the proposals for stabilizing the top of the mountain. Given the urgent need to ensure the safety of existing mining activities, they recommend that the Committee reiterate its request to install as soon as possible, a monitoring system to assess the stability of the mountain at regular intervals. They also recommend to the Committee that in the case of confirmation of the ascertained or potential danger to Outstanding Universal Value, or in case that no intervention will be undertaken as a matter of urgency to prevent any further collapse of the summit of the mountain, to consider the possible inscription of the property on the List of World Heritage in Danger.
