The Preliminary Environmental Assessment (EVAP) is a technical tool used to initially identify the potential environmental impacts of a project or activity before conducting a more in-depth evaluation, such as an Environmental Impact Study (EIA). Through this process, environmental risks can be detected early, laying the foundation for more informed and responsible decision-making in terms of sustainability.

In this article, we explain what the Preliminary Environmental Assessment is, when it is necessary, its benefits, and how it is carried out.

What is the Preliminary Environmental Assessment (EVAP)?

The EVAP is an initial study that provides a general overview of the potential effects of a project on the environment. This analysis is broader and less detailed than a full Environmental Impact Study, but it serves to determine whether a project has the potential to generate significant impacts or if a more in-depth evaluation is required.

This type of assessment is conducted in the early planning stages of a project when a final design has not yet been developed. Through the EVAP, the environmental components that may be affected by the proposed activity are identified, such as natural resources, biodiversity, nearby communities, air, water, and soil.

When is a Preliminary Environmental Assessment (EVAP) Required?

The EVAP is generally used in small or medium-sized projects that are not subject to a detailed Environmental Impact Study but still need to be evaluated from an environmental perspective. It is especially useful for activities whose scope is not entirely clear or where the magnitude of the impacts is not well defined.

Some examples of projects that may require an EVAP include:

• Small and medium-scale construction projects.
• Industrial activities with moderate potential impacts.
• Agricultural or forestry projects in sensitive areas.
• Urban or road infrastructure works.

The EVAP acts as a first filter to determine whether the project presents any relevant environmental risks that justify a more thorough evaluation.

Objectives of the Preliminary Environmental Assessment

The main objective of the EVAP is to enable early identification of potential environmental risks associated with a project. To achieve this, it aims to:

• Determine the environmental feasibility of the project in its early stages.
• Identify potential impacts and their magnitude (if any).
• Propose prevention and mitigation measures to minimize negative effects.
• Decide whether a detailed EIA is necessary or if the project can proceed with a simple declaration or preventive measures.

The EVAP also helps establish initial contact with environmental authorities to determine the type of evaluation required and ensure compliance with current regulations.

How is a Preliminary Environmental Assessment Conducted?

The Preliminary Environmental Assessment includes several key steps to ensure a proper analysis of the project’s potential impacts:

1. Project Description: A detailed description of the activities to be developed, including the project’s objectives, site characteristics, required resources, and estimated duration of the works or activities.
2. Identification of Environmental Components: Identification of the natural resources and environmental components that could be affected by the project, such as air, water, soil, flora, fauna, and nearby communities.
3. Assessment of Potential Impacts: Analysis of how the project’s activities could affect these components, considering their magnitude, duration, and reversibility. Although this analysis is preliminary, it helps detect potential issues that may require a deeper evaluation.
4. Proposal of Mitigation Measures: If negative impacts are identified, the EVAP proposes preventive and corrective measures to minimize or avoid these impacts. These measures may include design modifications, resource use restrictions, or the implementation of clean technologies.
5. Recommendations: Based on the EVAP results, recommendations are issued regarding the project’s environmental feasibility and whether a more detailed assessment like an Environmental Impact Study is necessary.

Benefits of the Preliminary Environmental Assessment

The EVAP offers several advantages for project developers, authorities, and the community in general:

• Early risk detection: Identifies potential impacts before the project progresses, helping to reduce future costs and delays if modifications are needed.
• Regulatory compliance: Ensures that projects meet legal and environmental requirements, avoiding sanctions or delays in project approval.
• Sustainability: Contributes to making projects more sustainable by minimizing negative effects on natural resources and promoting responsible land-use practices.
• Effective planning: Provides key information for proper project planning, ensuring that the right decisions are made from the start.

Why is the EVAP Important for Sustainable Development?

The Preliminary Environmental Assessment plays a crucial role in the sustainable development process. By conducting an early assessment of environmental impacts, informed decisions can be made that not only protect the environment but also promote the responsible use of resources and ecosystem integrity. The EVAP helps balance development needs with environmental preservation, contributing to a greener and more equitable future.

Conclusion

The Preliminary Environmental Assessment (EVAP) is a fundamental tool for identifying environmental risks from the early stages of a project. Being a broader and less expensive analysis than a detailed Environmental Impact Study, it allows potential issues to be detected in time, proposes corrective measures, and, in some cases, avoids the need for a more exhaustive evaluation. This not only ensures regulatory compliance but also promotes sustainable and responsible development, minimizing negative impacts on the environment and communities.
