Public information on the macro-farm of 3,059 sows in Monzón

The Aragonese Institute of Environmental Management (INAGA), under the Department of Environment and Tourism of the Government of Aragon, has opened the public information process for the environmental impact study and the basic project for the Integrated Environmental Authorization of a pig farm with 3,059 breeding sows in the municipality of Monzón (Huesca). The announcement was published in the Official Gazette of Aragon number 220, dated November 13, 2026, with the official reference BOA20261113023 and file number INAGA 500305/02/2026/08893. The resolution corresponds to INAGA, and interested parties have 30 business days from the day following the publication to submit observations.

The project: 863.99 LSU in polygon 36

The application was submitted by Cooperativa D’Ivars, SCCL, which is requesting the Integrated Environmental Authorization to build a piglet production farm. The announcement details the declared capacities:

3,059 breeding sows with their piglets up to 6 kilograms.
696 replacement gilts.
6 boars.
863.99 livestock units (LSU) as total equivalent capacity.

The facility would be located in polygon 36, plots 9 and 48, in the municipality of Monzón, in the province of Huesca. INAGA considers that the execution of the project “will not produce significant environmental effects on another European Union State,” therefore no cross-border consultation phase will be opened.

Thirty days and exclusively via electronic means

The process is handled in accordance with Article 55 of Law 11/2014, of December 4, on Environmental Prevention and Protection of Aragon, and includes both the public information of the environmental impact study and the consultation of interested persons and affected public administrations. The conditions for the participation period are as follows:

Deadline: 30 days from the day following the publication of the announcement in the BOA.
Body before which it is presented: the Aragonese Institute of Environmental Management.
Format: exclusively electronic, in accordance with the fourth additional provision of Law 10/2013, of December 19, of the Aragonese Institute of Environmental Management, modified by Law 1/2021, of February 11, on administrative simplification.
Accepted channels: any electronic registry of the Administration, preferably the electronic office indicated in the announcement itself.
Consultable documentation: environmental impact study and basic project, available at the INAGA electronic office (https://www.aragon.es/inaga/informacionpublica).

Who decides and with what effects

The competence to formulate the environmental impact statement and to resolve the application for Integrated Environmental Authorization corresponds to the Aragonese Institute of Environmental Management. The granting, if applicable, falls to the Director of the organization, and the authorization is configured as the definitive administrative resolution, against which the appropriate appeals may be filed.

The environmental impact statement is not issued as a separate act: it will be integrated into the same integrated environmental authorization resolution, as established by article 56 of the aforementioned Law 11/2014. The announcement appears signed in Zaragoza, on October 23, 2026, by Diana Remón Galindo, Head of Area III.

A second porcine file in the same municipality

The announcement is added to another procedure from the same organization in Monzón: the public information, published on November 12, 2026, in the Official Gazette of Aragon, regarding the environmental impact study and the basic project for Integrated Environmental Authorization for the expansion of a fattening pig farm up to 3,998 places (479.76 LSU) in polygon 38, plot 182, in Selgua, with file number INAGA 500305/02/2025/10507. Both files share the same competent body, a 30-day period, and the same electronic channel for participation.

File INAGA 500305/02/2026/08893 directly concerns the residents of Monzón and Selgua, the irrigation communities of the area, and the organizations that monitor the development of industrial pig farms in Aragon. With 863.99 LSU, the facility is among the largest farms subject to integrated environmental authorization in the region, meaning that the 30-day period now open is the only formal window for individuals, city councils, and affected entities to submit allegations to the file before INAGA resolves it. The full text of the announcement and the technical documentation can be consulted on the organization’s electronic headquarters.
