Quellaveco submits the fifth modification of its environmental study to public consultation

Anglo American Quellaveco S.A. has submitted to the National Service of Environmental Certification for Sustainable Investments (Senace) the “Fifth Modification of the Detailed Environmental Impact Study of the Quellaveco Mining Unit,” thereby opening the citizen participation stage of the procedure. The official notice was published in the Official Bulletin of the Official Gazette El Peruano on Monday, October 19, 2026, pages 28 and 29, with reference 081-2565112-1. Citizens have 15 calendar days from that publication to submit contributions, comments, or observations to Senace.

The process is based on Article 138 of the Environmental Protection and Management Regulation for Mining Exploitation, Processing, General Labor, Transport, and Storage Activities, approved by Supreme Decree No. 040-2014-EM, and Article 20 of the Rules regulating the Citizen Participation Process in the Mining Subsector, approved by Ministerial Resolution No. 304-2008-MEM/DM. The project under evaluation is located in the department of Moquegua, and the assigned file number is M-EIAD-00190-2026.

The planned mechanisms

According to the Citizen Participation Plan of the Fifth MEIA-d Quellaveco, the company will deploy six mechanisms:

• Publication of notices in the official gazette El Peruano and in the newspaper Prensa Regional, radio announcements on Radio Americana (95.7 FM), and the posting of A2-sized posters in public venues.
• Access to the full content of the study and its Executive Summary, in printed, digitized, and audiovisual versions.
• Operation of Permanent Information Offices (OIP) in Moquegua, Ilo, and Torata.
• Distribution of a graphic brochure among stakeholders in the social area of influence.
• Interaction with the population through a team of facilitators.
• Submission of contributions, comments, or observations to the competent authority.

The OIPs will be open Monday to Thursday from 8:00 to 13:00 and from 14:30 to 18:00, and Fridays from 8:00 to 12:30 and from 13:30 to 17:00. Their locations are Ancash Street No. 453, in the district of Moquegua; Abtao Jr. No. 910, in Ilo; and Coronel La Torre Street No. 24, in Torata. The contact channels are the telephone line 053-309 224, WhatsApp 939 551 443, and the email aateescucha@angloamerican.com.

Communities and modification zone

The interaction mechanism with facilitators will be applied in the localities located in the proposed modification zone, consisting of the Tumilaca-Pocata-Coscore-Tala Peasant Community, the Asana Peasant Community, and the Calientes Benito Huacanane Annex, in the districts of Torata and Samegua, Mariscal Nieto province, Moquegua region.

The content of the study and its Executive Summary will also be available at the Regional Directorate of Energy and Mines of Moquegua and in a set of municipalities:

• Provincial Municipality of Mariscal Nieto and Provincial Municipality of Ilo.
• District Municipalities of Carumas, San Cristóbal, Cuchumbaya, Torata, Samegua, San Antonio, Pacocha, and El Algarrobal.
• Peasant communities of Aruntaya, Asana, and Tumilaca-Pocata-Coscore-Tala.
• Populated Center of Titire, annexes of Huachunta, Chilota, and Calientes Benito Huacanane, Populated Center of Chen Chen, and the locality of San Antonio.

How to submit observations

Contributions should be addressed to the Directorate of Environmental Evaluation for Natural and Productive Resource Projects (DEAR) of Senace, through the Digital Filing Office module (https://enlinea.senace.gob.pe/mpd) or the email participacionciudadana@senace.gob.pe. The deadline is fifteen (15) calendar days from the publication of the notice in El Peruano, that is, until November 3, 2026.

The digital version of the file can be consulted on the Information Platform of the Single Window for Environmental Certification of Senace (https://www.senace.gob.pe/eva/), by entering Citizen Consultation and the file number M-EIAD-00190-2026. Copies of the documents may be requested from the authorities indicated in the notice.

The opening of this stage is decisive for the communities of Torata and Samegua, which will be able to review the scope of the fifth modification of the mine’s environmental instrument and establish a position before Senace before the agency resolves the evaluation. File M-EIAD-00190-2026 therefore concentrates the citizen observations that could condition the environmental viability of the changes proposed by Anglo American Quellaveco S.A. in Moquegua.
