Environmental Impact Assessment

A structured, evidence-based EIA that identifies real project risks early and gives the reviewing authority a clear, defensible basis for its decision.

Overview

An environmental impact assessment (EIA) is a systematic study that identifies, predicts and evaluates the likely environmental effects of a proposed project before it is approved. In Saudi Arabia, it determines the project's environmental classification, defines mitigation and monitoring measures, and forms the basis of the environmental permit application reviewed by the National Center for Environmental Compliance (NCEC).

Under the Environmental Law and its Implementing Regulations, projects that may affect the environment must be classified and, depending on their category, assessed before construction or operation can begin. The EIA is the document that carries this assessment. It describes the project and its alternatives, establishes the existing environmental and social conditions, and predicts how construction and operation will change them. A well-prepared EIA links each significant impact to a specific mitigation measure and to a monitoring commitment that can be verified later.

For project owners, the EIA is also a planning tool. Baseline surveys of air, noise, soil, groundwater, ecology and land use often reveal constraints that are far cheaper to address at design stage than after contracts are signed. Early screening shows which studies are needed and which are not, so field work, modelling and specialist input are scoped to the actual risk of the project rather than to a generic checklist. This keeps the study proportionate and the schedule realistic.

Selorin manages the full EIA process: screening and classification, scoping, baseline data collection, impact prediction, environmental risk assessment, mitigation design and report preparation. Where the project category requires it, we plan and document stakeholder input. After submission, we prepare structured responses to review comments from the NCEC and, where relevant, from bodies such as the Royal Commission for Jubail and Yanbu or MODON, and we translate the approved commitments into the environmental management plans your contractors will implement.

When you need this service

You may need this service when:

  • You are planning a new industrial, infrastructure or development project that requires an environmental permit.
  • You need to confirm your project's environmental classification under the Implementing Regulations.
  • An existing facility is expanding capacity, adding processes or changing its fuel or raw materials.
  • The reviewing authority has returned comments on a submitted EIA and requested clarifications.
  • Lenders or investors require an independent environmental and social risk assessment of the project.
  • Your project site lies near sensitive receptors such as communities, coastlines, wadis or protected areas.

What we deliver

01

Screening and classification

Review of project scope, location and activities to determine the likely environmental category and the level of study the Implementing Regulations require.

02

Scoping report

Definition of study boundaries, key environmental aspects, alternatives to consider, data gaps and the baseline survey programme needed to close them.

03

Baseline studies

Field surveys and desk studies covering air quality, noise, soil, groundwater, ecology, land use and social conditions within the defined study area.

04

Impact and risk assessment

Prediction and evaluation of construction and operational impacts, including environmental risk assessment of accidental releases and other non-routine events.

05

Mitigation and monitoring measures

Practical, costed-in-principle measures for each significant impact, with monitoring parameters, locations and frequencies that can be verified during implementation.

06

EIA report and review support

A complete EIA report prepared for submission, followed by structured responses to authority review comments until the study is accepted.

Our approach

  1. Screen and classify

    We review project information, site location and planned activities to confirm the likely classification and the scope of assessment required.

  2. Scope the study

    We define key aspects, study area, alternatives and data needs, and agree the baseline programme with your project team.

  3. Establish baseline

    We collect field and secondary data on environmental and social conditions, using documented sampling methods and locations.

  4. Assess impacts

    We predict impacts for construction and operation, rate their significance and assess environmental risks from non-routine events.

  5. Design mitigation

    We define mitigation, monitoring and management measures and, where required, document stakeholder input and how it was addressed.

  6. Report and respond

    We prepare the EIA report, support its submission and respond to review comments until the authority closes the review.

Regulatory context

  • Environmental Law (2020) and its Implementing Regulations, including the requirements for environmental classification and impact assessment of projects.
  • National Center for Environmental Compliance (NCEC), which reviews EIA studies and issues environmental permits.
  • Royal Commission for Jubail and Yanbu (RCJY) and MODON, where projects are located within their jurisdictions and their environmental requirements apply.
  • National Center for Wildlife (NCW) and National Center for Vegetation Cover Development and Combating Desertification (NCVC), where projects may affect habitats or vegetation.
  • Lender and investor environmental and social requirements, where the project is externally financed.

Requirements vary by activity, location and permit conditions. We confirm the applicable requirements for your project at the start of every engagement.

Frequently asked questions

Does every project in Saudi Arabia need a full EIA?

No. The Implementing Regulations classify projects according to their potential environmental impact, and the level of assessment depends on that classification. Some projects need only limited documentation, while others require a detailed study with baseline surveys and impact modelling. Screening at the start of the project confirms which category is likely to apply, so you do not commission more study than the project requires, or less than the authority will expect.

What information do you need from us to start?

We typically need a project description, site location and layout, the main processes and equipment, expected raw materials, utilities, emissions, effluents and wastes, and the construction schedule. Early-stage design information is sufficient for screening and scoping. Where details are not yet fixed, we work with stated assumptions and update the assessment as the design develops, recording each change so the final report remains consistent.

How long does an EIA take?

Duration depends on the project category, the size of the study area, the number of baseline surveys and whether seasonal data is needed. Authority review time also varies by project. We give you a programme after scoping, once the required studies are known, and we identify the activities on the critical path so that your design and procurement schedule can be planned around them.

What happens if the authority returns comments on the EIA?

Review comments are a normal part of the process. We log every comment in a response matrix, prepare a clear technical answer for each one, revise the relevant report sections and, where additional data is needed, explain how and when it will be provided. This keeps the exchange traceable and helps the reviewer close each point without repeated rounds of clarification.

How does the EIA connect to construction and operation?

The mitigation and monitoring measures approved in the EIA become commitments that must be implemented on site. We translate them into a construction environmental management plan and an operational environmental management plan, with clear responsibilities, monitoring schedules and records. This makes it easier to demonstrate compliance during inspections and when renewing or amending environmental permits later in the project life.
