Complete Guide to NCEC Environmental Permitting in Saudi Arabia (2026)

Saudi Arabia's National Center for Environmental Compliance (NCEC) has tightened the environmental permitting framework throughout 2025, and the changes coming into force in **2026** will reshape how industrial facilities, EPC contractors, and developers operate. Whether you are commissioning a new plant in Jubail, expanding a cement line in Yanbu, or relicensing a paint factory in Dammam, the NCEC environmental permit is the gate that determines whether your project can break ground, operate, or export. This complete 2026 guide walks you through the **NCEC permit categories**, document requirements, **Environmental Impact Assessment (EIA)** workflow, fees, timelines, and the four mistakes that cause most rejections — with practical advice from OzoneCo's NCEC-licensed consultants who have processed permits across 14 industrial sectors in the Kingdom. [image:1] ## What is the NCEC Environmental Permit? The NCEC environmental permit is now the **single mandatory clearance** for any activity that may impact air quality, water, soil, or biodiversity in Saudi Arabia. It is governed by the **Environmental Law (Royal Decree M/165)** and its 2025 executive regulations, and aligns with **Vision 2030** and the Saudi Green Initiative. A valid permit is required to: - Build, expand, or modify any industrial, mining, or energy facility - Operate emissions sources, wastewater outfalls, or waste treatment units - Import, store, or handle hazardous chemicals - Run quarries, asphalt plants, or large construction sites - Renew commercial registration for environmentally regulated activities > Without a current NCEC permit, facilities face administrative shutdown, fines up to **SAR 10 million**, and personal liability for plant managers under Article 26 of the Environmental Law. ## NCEC Permit Categories in 2026 ### Category A — Major Impact Refineries, petrochemical complexes, cement plants, steel mills, power stations >50 MW. Requires a **full EIA**, public disclosure, and CEMS. ### Category B — Moderate Impact Food processing, pharmaceuticals, paint, plastic compounding, automotive, mid-size data centers. Requires an **Initial Environmental Examination (IEE)** and periodic stack testing. ### Category C — Minor Impact Workshops, light assembly, warehousing of non-hazardous materials. Requires a **simplified self-declaration**. [callout: Tip — projects on the Category A/B boundary should request an early-scoping meeting with NCEC to lock the classification before spending on studies.] ## The 7-Step NCEC Permitting Workflow [image:2] 1. **Pre-screening** — submit project profile via the NCEC e-portal. 2. **Scoping** — define EIA terms of reference. 3. **Baseline studies** — air, noise, soil, groundwater, biodiversity by NCEC-accredited labs. 4. **Impact assessment** — modelling (AERMOD, MIKE) and risk evaluation. 5. **Environmental Management Plan (EMP)**. 6. **Public consultation** — required for Category A. 7. **Decision and conditions** — permit issued with binding limits and reporting calendar. ## Timelines and Fees You Should Plan For - Category A (full EIA): **9 to 14 months** - Category B (IEE): **4 to 7 months** - Category C: **3 to 6 weeks** Government fees range from SAR 5,000 (Category C) to SAR 250,000+ for major refineries.

[callout: A well-prepared file with current baseline data and a quantitative EMP cuts review time by an average of **38%**.] ## Renewals and Amendments Permits are issued for **3 to 5 years**. Renewals must be submitted **120 days before expiry**. Process changes (new feedstock, capacity uplift >10%, new emission point) trigger a **permit amendment**. ## How OzoneCo Helps You Secure the NCEC Permit OzoneCo is an **NCEC-licensed environmental consultancy** with a track record of approvals across petrochemicals, cement, food, pharma, and energy in Saudi Arabia.
