Environmental Law and Community Relations

Projects and activities expressly listed by Law No. 19,300 (Ley N° 19.300) must be submitted to the Environmental Impact Assessment System (SEIA), for example certain energy, industrial, real estate, agro-industrial, mining, or infrastructure projects that exceed the thresholds set by the regulation. The assessment is processed before the Environmental Evaluation Service (SEA), created by Law No. 20,417 (Ley N° 20.417). Determining whether a project must enter the system, and through which route, is key: carrying out an activity that required assessment without having obtained it exposes you to penalties and even to a shutdown of the works. It is advisable to analyze the case from the project’s design stage.

They are the two ways of entering the Environmental Impact Assessment System (SEIA). The Environmental Impact Statement (DIA) applies when the project does not generate the significant effects or circumstances listed in Law No. 19,300 (Ley N° 19.300); it is a more limited procedure. The Environmental Impact Study (EIA) is required when the project can indeed generate those effects, such as risk to health, impact on natural resources or communities, or alteration of heritage; it involves a deeper analysis, mitigation measures, and, normally, citizen participation processes. Correctly classifying the project avoids rejections and delays, so it is advisable to assess it with technical and legal advice.

Indigenous consultation is a good faith dialogue process that the State must carry out with Indigenous peoples when an administrative measure or a project is liable to affect them directly, in accordance with ILO Convention 169. In the case of investment projects, it is usually channeled within the Environmental Impact Assessment System (SEIA) when the assessment detects a possible impact on communities or on their lands and customs. It is not a mere informational formality: it seeks to reach agreements and must be carried out in a prior, informed, and appropriate manner. Early, well-managed community engagement reduces the risk of challenges and of conflicts during execution.

The Superintendency of the Environment (SMA), created by Law No. 20,417 (Ley N° 20.417), oversees compliance with environmental permits (resoluciones de calificación ambiental) and with the sector’s regulations. If it brings charges, the holder has a deadline to submit its defenses and, in certain cases, to enter into a compliance program that allows it to correct the infringements and mitigate or avoid the penalty. Fines can be high and, in the most serious cases, can lead to closure or to revocation of the environmental permit. That is why it is key to act within the deadline, with a technical and legal strategy, and to properly document the corrective measures adopted.

Permitting (permisología) is the set of permits, authorizations, and sector approvals that a project needs in order to be built and to operate, in addition to its environmental assessment: for example construction, health, water, electrical, or land-use permits, before different State agencies. Delays usually arise from sequential procedures, requirements discovered late, or incomplete background information. A good strategy identifies from the outset all the applicable permits, their order, and their timelines, and coordinates their processing in parallel where possible. Anticipating permitting avoids cost overruns and the halting of the project.

Poor community engagement is today one of the main risks for an investment project. It can translate into a challenge to the environmental permit before the Environmental Courts or the Court of Appeals, into claims over an Indigenous consultation carried out improperly under ILO Convention 169, into conflicts and on-site work stoppages, and into reputational harm. Beyond the strictly legal, social license is decisive for the project’s viability. That is why it is advisable to integrate dialogue with communities from the design stage, with clear and documented agreements, and not to treat it as a final formality.
