When is AMDAL Required? The Complete Guide to Indonesia's Environmental Impact Assessment Triggers
1.0 Understanding Indonesia's AMDAL Requirement Framework
Indonesia's Environmental Impact Assessment system, known as Analisis Mengenai Dampak Lingkungan Hidup (AMDAL), represents one of the most comprehensive pre-project environmental evaluation frameworks in Southeast Asia. Established as a fundamental instrument under the Environmental Protection and Management Law (UU 32/2009) and detailed through Government Regulation PP 22/2021 on the Implementation of Environmental Protection and Management, AMDAL serves as the mandatory gateway for all business activities and projects that may cause significant environmental impact. The regulation creates a sophisticated three-pathway system where businesses must first determine whether they require AMDAL, UKL-UPL (Environmental Management and Monitoring Efforts), or SPPL (Environmental Management and Monitoring Commitment Statement), with each pathway triggered by specific criteria related to activity type, scale, and location. Understanding exactly when AMDAL is required has become essential knowledge for project developers, environmental consultants, investors, and regulatory agencies, as the consequences of incorrect classification can range from project delays and permit denials to administrative sanctions and potential criminal liability under Indonesia's omnibus law framework. This article provides a systematic analysis of the AMDAL requirement triggers under PP 22/2021, examining the dual pathway system based on activity scale and protected area proximity, the nine criteria that define significant environmental impact, the comprehensive exemption framework, and the three-tier AMDAL category system that determines assessment rigor based on cumulative risk scoring.
2.0 The Two Primary AMDAL Triggers
PP 22/2021 establishes that AMDAL is mandatory for any planned business and/or activity (rencana Usaha dan/atau Kegiatan) that has Significant Impact (Dampak Penting) on the environment. Article 5 paragraph 2 specifies two distinct pathways that trigger this requirement.
2.1 Scale/Size-Based Requirements
| Trigger Category | Indonesian Term | Determining Factor | Result |
|---|---|---|---|
| Activity Scale | Besaran/Skala | Activity type meets ministerial threshold list | AMDAL mandatory |
| Production Capacity | Kapasitas Produksi | Exceeds specified output limits | AMDAL mandatory |
| Land Area | Luas Lahan | Exceeds specified hectare thresholds | AMDAL mandatory |
| Infrastructure Size | Ukuran Infrastruktur | Exceeds specified dimensions | AMDAL mandatory |
The first trigger pathway operates through a positive list system where specific activity types are assigned scale or size thresholds. When a proposed activity meets or exceeds these thresholds, AMDAL becomes automatically mandatory regardless of other factors. This list is maintained by the Ministry of Environment and Forestry and subject to evaluation at least every five years under Article 9.
2.2 Protected Area Location Requirements
| Protected Area Type (Indonesian) | English Translation | AMDAL Trigger |
|---|---|---|
| Kawasan hutan lindung | Protection forest areas | Within or adjacent |
| Kawasan lindung gambut | Peat protection areas | Within or adjacent |
| Kawasan resapan air | Water catchment areas | Within or adjacent |
| Sempadan pantai | Coastal buffer zones | Within or adjacent |
| Sempadan sungai | River buffer zones | Within or adjacent |
| Kawasan sekitar danau/waduk | Lake/reservoir areas | Within or adjacent |
| Suaka margasatwa | Wildlife reserves | Within or adjacent |
| Cagar alam | Nature reserves | Within or adjacent |
| Kawasan pantai berhutan bakau | Mangrove coastal areas | Within or adjacent |
| Taman nasional | National parks | Within or adjacent |
| Taman hutan raya | Grand forest parks | Within or adjacent |
| Taman wisata alam | Nature tourism parks | Within or adjacent |
| Kawasan cagar budaya | Cultural heritage areas | Within or adjacent |
| Kawasan cagar alam geologi | Geological reserves | Within or adjacent |
| Kawasan imbuhan air tanah | Groundwater recharge areas | Within or adjacent |
| Sempadan mata air | Spring buffer zones | Within or adjacent |
| Kawasan perlindungan plasma nutfah | Germplasm protection areas | Within or adjacent |
| Kawasan pengungsian satwa | Wildlife refuge areas | Within or adjacent |
| Terumbu karang | Coral reefs | Within or adjacent |
| Kawasan konservasi pesisir | Coastal conservation areas | Within or adjacent |
| Kawasan konservasi maritim | Maritime conservation areas | Within or adjacent |
| Kawasan konservasi perairan | Aquatic conservation areas | Within or adjacent |
| Kawasan koridor satwa | Wildlife corridor areas | Within or adjacent |
The second trigger operates through spatial proximity to any of the twenty-three protected area categories listed in Lampiran I. Any activity located within (di dalam) or directly adjacent to (berbatasan langsung dengan) these protected areas requires AMDAL unless specific exemptions apply.
3.0 The Nine Criteria for Significant Environmental Impact
Article 8 of PP 22/2021 defines nine criteria (kriteria) that characterize activities with significant environmental impact requiring AMDAL. These criteria function as the conceptual foundation for determining which activities warrant comprehensive environmental assessment.
3.1 Impact Criteria Matrix
| No. | Criterion (Indonesian) | English Translation | Example Activities |
|---|---|---|---|
| 3.1.1 | Pengubahan bentuk lahan dan bentang alam | Changes to land form and landscape | Land clearing, excavation, reclamation |
| 3.1.2 | Eksploitasi sumber daya alam terbarukan | Exploitation of renewable natural resources | Forestry, fisheries, agriculture |
| 3.1.3 | Eksploitasi sumber daya alam tidak terbarukan | Exploitation of non-renewable natural resources | Mining, oil and gas extraction |
| 3.1.4 | Proses yang menimbulkan pencemaran | Processes causing pollution | Manufacturing, waste processing |
| 3.1.5 | Proses yang menimbulkan kerusakan | Processes causing environmental damage | Heavy industry, resource extraction |
| 3.1.6 | Pemborosan sumber daya alam | Waste of natural resources | Inefficient extraction methods |
| 3.1.7 | Kemerosotan sumber daya alam | Degradation of natural resources | Unsustainable harvesting |
| 3.1.8 | Pengaruh terhadap lingkungan alam | Effects on natural environment | Habitat modification |
| 3.1.9 | Pengaruh terhadap lingkungan buatan | Effects on built environment | Infrastructure impacts |
3.2 Extended Criteria Analysis
| No. | Criterion (Indonesian) | English Translation | Regulatory Implications |
|---|---|---|---|
| 3.2.1 | Pengaruh terhadap lingkungan sosial budaya | Effects on social and cultural environment | Community consultation required |
| 3.2.2 | Pelestarian kawasan konservasi | Conservation area preservation | Heightened scrutiny |
| 3.2.3 | Perlindungan cagar budaya | Cultural heritage protection | Cultural impact assessment |
| 3.2.4 | Introduksi jenis tumbuhan | Introduction of plant species | Biosecurity evaluation |
| 3.2.5 | Introduksi jenis hewan | Introduction of animal species | Ecological risk assessment |

| 3.2.7 | Pembuatan bahan hayati | Manufacture of biological materials | Biosafety protocols |
| 3.2.8 | Penggunaan bahan nonhayati | Use of non-biological materials | Chemical safety review |
| 3.2.9 | Kegiatan berisiko tinggi | High-risk activities | Enhanced safety assessment |
| 3.2.10 | Pengaruh pertahanan negara | Effects on national defense | Security clearance required |
| 3.2.11 | Penerapan teknologi berpotensi besar | Application of high-impact technology | Technology assessment |
These criteria provide regulatory authorities with a conceptual framework for evaluating activities that may not appear on explicit threshold lists but nevertheless warrant AMDAL due to their inherent impact potential.
4.0 The Ten AMDAL Exemptions
Article 10 of PP 22/2021 establishes ten specific circumstances under which the AMDAL requirement may be exempted. Understanding these exemptions is critical for determining the appropriate environmental assessment pathway.
4.1 Strategic Environmental Assessment (KLHS) Exemptions
| Exemption Category | Condition | Alternative Requirement |
|---|---|---|
| RDTR with KLHS | Location in regency/city with detailed spatial plan and comprehensive KLHS | UKL-UPL or SPPL |
| Forest Management with KLHS | Location in forest area with management plan and comprehensive KLHS | UKL-UPL or SPPL |
| Government Program with KLHS | Government/Regional program with master plan and comprehensive KLHS | UKL-UPL or SPPL |
The first three exemptions under Article 10 paragraph 1 letters (a), (b), and (c) apply when the activity location is covered by a comprehensive Strategic Environmental Assessment (Kajian Lingkungan Hidup Strategis or KLHS). This requires that the KLHS be prepared and implemented using a holistic, integrative, thematic, and spatial approach (pendekatan holistik, integratif, tematik, dan spasial).
4.2 Protected Area Exemptions
| Exemption Category | Indonesian Description | English Translation |
|---|---|---|
| Exploration activities | Eksplorasi pertambangan, migas, panas bumi | Mining, oil/gas, geothermal exploration without AMDAL-scale supporting activities |
| Non-commercial research | Penelitian dan pengembangan nonkomersial | Research that does not disturb protected area functions |
| Conservation support | Kegiatan mendukung pelestarian kawasan | Activities supporting protected area preservation |
| Defense activities | Kepentingan pertahanan keamanan | National defense without significant impact |
| No significant impact | Kegiatan tidak berdampak penting | Activities demonstrably without significant impact |
| Indigenous cultivation | Budidaya penduduk asli | Indigenous people's cultivation with fixed area under supervision |
Article 10 paragraph 3 specifies six sub-categories of activities within or adjacent to protected areas that may qualify for exemption from the general protected area AMDAL trigger.
4.3 Area-Wide and Emergency Exemptions
| Exemption Category | Condition | Alternative Requirement |
|---|---|---|
| Area-wide AMDAL | Activity within area covered by existing kawasan AMDAL | Subject to area environmental approval |
| RKL-RPL rinci | Activity in area requiring detailed RKL-RPL under kawasan AMDAL | Detailed RKL-RPL |
| Disaster emergency | Conducted during disaster response | No environmental document |
| Environmental recovery | Government restoration in unlicensed areas | No environmental document |
| Authority exemption | Exemption granted by competent protected area authority | UKL-UPL or SPPL |
Notably, activities under Article 10 paragraph 1 letters (h) disaster emergency and (i) environmental recovery do not require any environmental document. All other exempted activities must still obtain either UKL-UPL or SPPL as confirmed by Article 11.
5.0 The AMDAL Category System and Screening Process
PP 22/2021 Lampiran I establishes a sophisticated three-tier AMDAL category system (A, B, C) based on cumulative risk scoring across four dimensions.
5.1 Risk Scoring Parameters
| Parameter | Indonesian Term | Scale 3 | Scale 2 | Scale 1 |
|---|---|---|---|---|
| Activity Complexity | Kompleksitas | Sangat kompleks | Cukup kompleks | Tidak kompleks |
| Environmental Impact | Dampak | Sangat Penting | Lebih Penting | Penting |
| Location Sensitivity | Sensitifitas Lokasi | Conservation area | Other protected area | Outside protected area |
| Carrying Capacity Status | D3TLH | Highly exceeded | Exceeded | Not exceeded |
Each proposed activity is evaluated across these four parameters, with each parameter receiving a score of 1, 2, or 3. The cumulative score determines the AMDAL category.
5.2 AMDAL Category Determination
| Category | Indonesian | Cumulative Score | Assessment Rigor | Typical Activities |
|---|---|---|---|---|
| A | Kategori A | > 9 | Highest | Nuclear plants, large-scale mining, activities in conservation areas |
| B | Kategori B | 6-9 | Medium | Medium industry, activities near protected areas |
| C | Kategori C | < 6 | Standard | Standard industrial activities outside sensitive areas |
When the Environmental Carrying Capacity Status (D3TLH) data is unavailable for a location, the category determination thresholds adjust: Category A applies when cumulative score > 6, Category B for scores 4-6, and Category C for scores < 4.
5.3 Eight-Step Screening Process
| Step | Indonesian Description | English Translation | Decision Point |
|---|---|---|---|
| 1 | Mengisi ringkasan informasi lingkungan | Complete environmental information summary | Information gathering |
| 2 | Pencocokan dengan daftar wajib Amdal | Match against mandatory AMDAL list | List verification |
| 3 | Evaluasi kegiatan utama/pendukung | Evaluate main and supporting activities | If on list: AMDAL required |
| 4 | Evaluasi lokasi kawasan lindung | Evaluate protected area proximity | Location assessment |
| 5 | Pencocokan kriteria pengecualian | Match against exemption criteria | If within protected area |
| 6 | Kesimpulan wajib UKL-UPL/SPPL | Conclude UKL-UPL or SPPL required | If exemption applies |
| 7 | Kesimpulan wajib Amdal | Conclude AMDAL required | If no exemption |
| 8 | Kesimpulan UKL-UPL/SPPL | Conclude UKL-UPL or SPPL for others | If outside protected area |
This eight-step screening process provides a systematic pathway for determining the appropriate environmental assessment requirement for any proposed activity.
Conclusion: Navigating Indonesia's AMDAL Framework
The AMDAL requirement framework under PP 22/2021 creates a comprehensive system for ensuring that business activities with significant environmental impact undergo rigorous environmental assessment before receiving operational permits. Project developers must systematically evaluate their proposed activities against three primary criteria: (1) whether the activity type and scale appear on the mandatory AMDAL list, (2) whether the location falls within or adjacent to any of the twenty-three protected area categories, and (3) whether any of the ten exemption pathways apply. For activities requiring AMDAL, the three-tier category system further determines the rigor and complexity of the required assessment based on activity complexity, impact significance, location sensitivity, and environmental carrying capacity status. Failure to correctly determine AMDAL requirements can result in permit denial, administrative sanctions, or project cancellation. Environmental consultants and project developers should maintain current knowledge of ministerial implementing regulations that specify activity-specific thresholds and procedural requirements for AMDAL preparation and approval.
