National detailed regulation for ESIA

Consolidated text of environmental management of the Ministry of the Environment (Texto Únificado de la legislación secundaria de manejo ambiental; TULSMA), published in official register No. 725 year 2002 Decree No. 3399.


Book I establishes the environmental authority
Book VI of environmental quality, title I describes the system of environmental management (Sistema Únificado de Manejo Ambiental; SUMA) that regulates the process of environmental impact assessment at national level.
The “Rules of implementation of social participation mechanisms” from 2008 (Decree Presidential No. 1014, Articles 9-22) establish social participation as a tool for knowledge, integration and the citizen initiative to strengthen the implementation of the process of environmental impact studies and reduce the margins of risk and environmental impact. 

The Ministerial Agreements No. 112 and 212 of 2008 establish citizen participation in the environmental licensing process approved by the Ministry of the Environment.

Central ESIA authority

The Ministry of Environment is the national environmental authority.

The Ministry of Environment may accredited other state agencies as Delegated Environmental Authorities (Autoridades Ambientales de Aplicación Responsable, AAAR) according to the unique system of environmental management (SUMA). The functions of the Delegated Environmental Authorities are regulated by a Ministerial Agreement.They can approve, reject or ask for modifications of the EIA, and approve or reject environmental licenses.

The Ministry of Environment manages a register and publishes on its website a list of bodies accredited to the SUMA.

Other key (governmental) parties involved in ESIA, and their roles

The National Electrification Council (CONELEC) is the Delegated Environmental Authority (AAAR) for the activities of the electricity sector (Ministerial Decision of 2005).

The Ministry of Natural Non Renewable Resources (MRNNR) is the ministry that regulates, promotes and develops policy for the mining and oil sector. The Ministry of Natural Non Renewable Resources coordinates with the Ministry of Environment in environmental matters.Environmental licenses for mining and oil and gas activities are awarded by the Ministry of the Environment. In 2009 the National Government issued the resolution (No. 1630) "Art, 1.- . transfer to the Ministry of the Environment, all competencies, authority, functions, and delegations related to environmental issues from the Department of Environmental Protection of the Ministry of Mines and Petroleum; the National Department of Mining and Environmental Protection (DINAPAM) and the National Department of Environmental Protection of Hydrocarbons (DINAPAH)".

Resolution no. 1630 of 2009

(De)centralisation of ESIA mandates

The provincial governments (that are accredited through the SUMA) have the authority to assess and approve studies of environmental impact assessments, environmental sheets, environmental management plans and environmental licenses.

Local municipalities of major cities such as Quito and Guayaquil are also accredited to the SUMA and function as Delegated Environmental Authorities.

Payment system

Payments for issuing of environmental licenses to the competent environmental authority is regulated by the regulation of the Ministry of the Environment (TULAS, book IX on “the rights or rates for the services provided by the Ministry of Environment and the use and exploitation of domestic goods that are under his charge and protection”).

Payments are made to the bank account of the Ministry of Environment of the Banco Nacional de Fomento.


ESIA procedure

to the top


Screening process

The proponent submits an application to the competent environmental authority in order to start the process of environmental licensing of the proposed activity. The proponent prepares a draft environmental sheet or in the case of possible significant negative environmental impacts the proponent directly prepares draft terms of reference. The competent environmental authority (the Ministry of the Environment or AAAR) reviews the draft.

Environmental sheets and draft ToR are revised by the Delegated Environmental Authority (Autoridad Ambiental de Aplicación Responsable, AAAR); the Ministry of Environment or another State Agency accredited to the SUMA. The authorities request additional information, approve or reject the sheets or draft ToR. 

Sensitive areas

The classification takes into account whether the proposed activity or work affects national protected areas. All activities, projects or works in the state protected areas, protective forests and forest heritage areas are subject to the preparation of environmental impact assessment, and must be processed by the Ministry of Environment. Protected areas are legalized and managed through the National System of Protected Areas (Sistema Nacional de Áreas Protegidas, SNAP).

Procedures for the Galapagos Islands are subject to the special law for the Galapagos Island region. The law dictates that "… all actions proposed for its implementation or execution in such jurisdiction shall be subject to environmental impact assessment process ".

Contents of the starting document

The minimum content of the starting document is:

  • Data of the proponent
  • A brief description of the project, activity or work
  • Location (important to note whether located within and/or influencing a protected area, protective forest, or forest heritage area)
  • Significance of environmental impacts (physical, biotic, landscape, cultural, social and economic)
  • Waste generation
  • Legislation
  • Level of social acceptability
  • Location in indigenous territories
  • Archaeological sites

The document has attached: the certification of land use granted by the municipality where the project located; as well as: identity document, legal document of the legal representative; and payment to the Banco Nacional de Fomento.

Timeline Screening

11-20 day


Scoping process

Development of the scope of the EIA is required. In the case the project, activity or work might generate negative environmental impacts, the proponent develops terms of reference for an environmental impact assessment. The terms of reference determine scope, focus, and the methods to be applied in carrying out the environmental impact assessment. The ToR are elaborated on the base of the characteristics of the activity or proposed project including the criteria obtained through citizen participation. The environmental authority reviews, and if necessary modifies, the draft terms of reference. After this the environmental authority approves of rejects the ToR.

For mining activities the Ministry of Environment established technical rules of the content, features, and minimum conditions of the terms of reference for the elaboration of environmental impact studies.

Assessment process

The proponent develops the EIA with a multidisciplinary team. In the baseline and evaluation the following issues are taken into account: physical, biological, landscape, cultural, social, economic and archaeological issues. The environmental management plan must be developed to minimize, mitigate and compensate for significant environmental impacts. The contingency plan is included. It is important to develop mechanisms to involve civil society in the area of influence.

The proponent submits a draft environmental impact assessment to the competent environmental authority and makes it available to the public. After this the process enters into the public participation process. The proponent organizes the public participation in coordination with the environmental authority.

General Environmental Law

Accreditation of consultants

The Ministry of Environment has a central register of authorized entities that are accredited to conduct environmental studies.


Review process

If only an environmental sheet is required, the Delegated Environmental Authority (AAAR) reviews the environmental sheet. And if the environmental sheet is approved the environmental license will be issued.
Where an environmental impact assessment is required, the proponent presents the environmental impact assessment before the AAAR. The AAAR reviews the environmental impact assessment and reviews the compliance with the public participation. The AAAR reviews in coordination with the Environmental Authority for Coordination (Autoridad Ambiental de Aplicación de Coordinación, AAAC).  AAAC are the governmental authorities which are involved in the EIA process but are not accredited to take decisions.

In the process of reviewing the public may observe and comment on the draft of the environmental impact assessment.

Review expertise

In the process of reviewing the Environmental Authorities for Coordination (Autoridades Ambientales de Aplicación de Coordinación, AAAC) plays a role as advisor.

For projects, activities and works in state protected areas, forest heritage areas and protective forest the Department of Environmental Quality of the Ministry of Environment reviews and coordinates the assessment of environmental impacts with the Directorate of Biodiversity and Forestry Division of the Ministry of Environment. 

Decision making

Integration of ESIA into decision-making

The environmental license is a requirement prior to the execution of the project, activity or work involving environmental risk.

The Ministry of Environment, which is the National Environmental Authority and the Delegated Environmental Authority (AAAR) are the authorities to take the decision on the approval or rejection of environmental licenses.

In the case of activities, projects or works proposed by an AAAR the Ministry of Environment is the competent authority. In the event that the Ministry of Environment is the proponent of an activity, work or subject to environmental license the National Council for Sustainable Development determines the authority.

Decision justification

The competent environmental authority specifies the technical and legal considerations underlying the decision.

The ministerial resolution of environmental license approval is published.
