Prakas No. 3591 \u2014 issued on 6 May 2025 and in force from 6 June 2025 \u2014 sorts development projects into three control tiers (EPA, IEIA and FEIA), each with a statutory review limit of 30, 60 and 90 business days respectively. For light-industry manufacturers, the EPA (Environmental Protection Agreement) is currently the most time-efficient compliance route. This article explains the logic of Cambodia&#8217;s three-tier system and shows how locating in the Manhattan Special Economic Zone (MSEZ) \u2014 with its park-level Master EIA and shared green infrastructure \u2014 can help companies achieve fast, compliant setup while protecting their long-term ESG standing in international supply chains.<\/strong><\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-1\"><strong><strong>1. The EIA challenge in Southeast Asia: pressure on both time and cost<\/strong><\/strong><\/h2>\n\n\n\n<p style=\"font-size:16px\">For manufacturers planning to shift capacity into Southeast Asia, the environmental impact assessment (EIA) is often one of the biggest sources of uncertainty in the early project phase.<\/p>\n\n\n\n<p style=\"font-size:16px\">Under the previous framework \u2014 Cambodia&#8217;s Prakas No. 021 (2020) \u2014 classification was relatively blunt: most industrial investment projects were required to complete the full EIA process regardless of their size or pollution profile. Engaging a third-party consultant for field sampling and report preparation, followed by lengthy government review and public consultation, could mean tens to hundreds of thousands of US dollars in up-front advisory costs and an unpredictable approval timeline \u2014 a serious constraint when a company is trying to meet international order deadlines. <\/p>\n\n\n\n<p style=\"font-size:16px\">To direct regulatory attention toward higher-risk industries while easing the path for lower-impact ones, the MoE \u2014 building on the Environment and Natural Resources Code promulgated on 29 June 2023 \u2014 launched a modernization of the EIA regime in 2025, creating a clear, risk-based classification system.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-2\"><strong><strong>2. Cambodia&#8217;s new rules: Prakas 3591 establishes a three-tier system<\/strong><\/strong><\/h2>\n\n\n\n<p style=\"font-size:16px\">Prakas No. 3591, in force from 6 June 2025, is the cornerstone of this reform. Its key features:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:16px\">Risk-based classification: development projects are sorted into three control tiers according to industry type and investment scale.<\/li>\n\n\n\n<li style=\"font-size:16px\">Wider coverage: the controlled list expands from 197 to 238 project types (141 new activities added), covering mining, energy, industrial manufacturing, tourism development and infrastructure.<\/li>\n\n\n\n<li style=\"font-size:16px\">Statutory review limits: each tier has a defined business-day ceiling, making approval far more predictable.<\/li>\n<\/ul>\n\n\n\n<p style=\"font-size:16px\">An important clarification: this is precise tiering, not deregulation. Every project on the controlled list must still match the right tier and complete its environmental filing \u2014 but the compliance burden is now proportionate to the project&#8217;s actual environmental impact. For light industry, that is a structural advantage that can shorten the overseas setup timeline.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"section-2-1\"><strong>The three tiers: <strong>EPA<\/strong>, IEIA and <strong>FEIA<\/strong><\/strong><\/h3>\n\n\n\n<figure class=\"wp-block-table is-style-stripes\" style=\"padding-top:0;padding-right:var(--wp--preset--spacing--40);padding-bottom:0;padding-left:var(--wp--preset--spacing--40)\"><table class=\"has-fixed-layout\" style=\"border-width:26px\"><thead><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Tier<\/strong><\/td><td><strong>Full name<\/strong><\/td><td><strong>Typically applies to<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Statutory review limit<\/strong><\/td><\/tr><\/thead><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>EPA<\/strong><\/td><td>Environmental Protection Agreement<\/td><td>Low-impact projects; most light-industry manufacturing<\/td><td class=\"has-text-align-center\" data-align=\"center\">Up to 30 business days<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>IEIA<\/strong><\/td><td>Initial Environmental Impact Assessment<\/td><td>Medium-impact projects<\/td><td class=\"has-text-align-center\" data-align=\"center\">Up to 60 business days<\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>FEIA<\/strong><\/td><td>Full Environmental Impact Assessment<\/td><td>High-impact projects; heavy or polluting industry, large infrastructure<\/td><td class=\"has-text-align-center\" data-align=\"center\">Up to 90 business days<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"section-2-2\"><strong>EPA: the most efficient route for light industry<\/strong><\/h3>\n\n\n\n<p style=\"font-size:16px\">For light-industry manufacturers, the EPA route is the best balance of compliance and speed under the new system:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:16px\">Streamlined documentation: compared with IEIA and FEIA, the EPA significantly reduces requirements for baseline surveys, impact prediction and pollution-control design.<\/li>\n\n\n\n<li style=\"font-size:16px\">A 30-business-day ceiling: replacing the open-ended timelines of the old single-track EIA with a predictable schedule.<\/li>\n\n\n\n<li style=\"font-size:16px\">Ongoing compliance still applies: a simpler approval does not remove ongoing obligations. Under Prakas No. 6985 (25 August 2025), every project approved at EPA, IEIA or FEIA level must maintain an internal environmental management system and submit a quarterly or semi-annual Environmental Monitoring Report (EMR) to the MoE.<\/li>\n\n\n\n<li style=\"font-size:16px\">SMEs must attach an EMP: under Prakas No. 9540 (26 November 2025), small and medium factories applying for an EPA must also submit an Environmental Management Plan (EMP) as part of routine operating compliance.<\/li>\n<\/ul>\n\n\n\n<p style=\"font-size:16px\">In short, the EPA route is about lower cost and higher efficiency \u2014 not a compliance exemption. Companies should confirm the correct tier early, ideally with a knowledgeable local partner, to avoid start-up delays caused by misclassification.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-3\"><strong>3. Who benefits: the typical &#8220;EPA-tier&#8221; light-industry profile<\/strong><\/h2>\n\n\n\n<p style=\"font-size:16px\">Final classification always depends on a project&#8217;s specific investment amount and processes. But based on the logic of Prakas 3591 and common international screening criteria, sectors with low energy use, no toxic or hazardous chemicals, and no direct heavy-metal wastewater discharge are the most likely EPA beneficiaries:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:16px\">Light assembly and consumer electronics: component assembly and contract manufacturing that does not require high-grade clean rooms.<\/li>\n\n\n\n<li style=\"font-size:16px\">Traditional consumer light industry: garment sewing (excluding dyeing\/finishing), footwear, bags and leather goods.<\/li>\n\n\n\n<li style=\"font-size:16px\">Hardware and light metalworking: metal processing without electroplating; dry assembly of auto components.<\/li>\n\n\n\n<li style=\"font-size:16px\">Packaging and furniture: paper packaging; wooden furniture (excluding high-VOC coating processes).<\/li>\n<\/ul>\n\n\n\n<p style=\"font-size:16px\">Because their environmental load is comparatively low, these sectors can avoid the longer IEIA or FEIA routes and compress the pre-production lead time from what was often half a year to within a single quarter.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-4\"><strong><strong>4. <a href=\"https:\/\/www.manhattansez.com\/en\/why-choose-msez\/\" data-type=\"page\" data-id=\"6149\">Manhattan SEZ (MSEZ)<\/a>: a compliance advantage in the tiered-EIA era<\/strong><\/strong><\/h2>\n\n\n\n<p style=\"font-size:16px\">Management teams should keep one principle in mind: a simpler host-country procedure does not mean international buyers have relaxed their ESG supply-chain audits. When major global brands run supplier (factory) ESG audits, they continue to scrutinize wastewater discharge, solid-waste handling and the share of renewable energy used. Globally recognized standards such as the Higg Index, SMETA and ZDHC do not loosen because a project&#8217;s local EIA tier is lower. This is where an established SEZ can add real value.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"section-4-1\"><strong><strong>Park-level Master EIA accelerates EPA filing<\/strong><\/strong><\/h3>\n\n\n\n<p style=\"font-size:16px\">MSEZ (about 600 hectares, with more than 40,000 industrial workers) obtained official EIA approval at the master-planning stage. Companies locating in the park benefit from:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li style=\"font-size:16px\">Direct use of the park&#8217;s environmental baseline database \u2014 saving the time and cost of outsourcing hydrology, soil and air monitoring.<\/li>\n\n\n\n<li style=\"font-size:16px\">Reuse of the park&#8217;s existing EMP framework \u2014 easing the later EMR monitoring obligation.<\/li>\n\n\n\n<li style=\"font-size:16px\">The park&#8217;s compliance track record as supporting evidence when filing with the MoE, improving first-time approval rates.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"section-4-2\"><strong><strong>Centralized effluent treatment and renewable power for ESG audits<\/strong><\/strong><\/h3>\n\n\n\n<p style=\"font-size:16px\">Companies that build on standalone land outside a park can struggle to provide the wastewater-treatment evidence that European and US buyers demand. MSEZ has built a Centralized Effluent Treatment Plant (CETP) to international standards: tenants connect domestic and low-concentration industrial wastewater to the park network for compliant treatment. Combined with the park&#8217;s reserved capacity for solar power expansion, this lets companies enjoy the EPA&#8217;s faster approval internally while still meeting buyers&#8217; Scope 3 carbon and environmental-audit requirements externally.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"section-4-3\"><strong>Full-lifecycle compliance under the Prakas 6985 monitoring rules<\/strong><\/h3>\n\n\n\n<p>Under Prakas No. 6985, every approved project must keep internal environmental records and submit an EMR to the MoE quarterly or semi-annually \u2014 an ongoing obligation across the project&#8217;s life. MSEZ has an in-house compliance team working in Chinese, English and Khmer that can provide end-to-end support: planning monitoring indicators, sampling methods and frequency in line with the approved EMP; centrally managing permits and regulatory files; drafting and submitting the periodic EMR; and tracking the latest enforcement guidance, including the SME-focused Prakas 9540.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-5\"><strong>5. Conclusion<\/strong><\/h2>\n\n\n\n<p style=\"font-size:16px\">Cambodia&#8217;s three-tier EIA system replaces a slow, one-size-fits-all model with risk-based, targeted oversight. For light industry, the EPA route&#8217;s 30-business-day statutory ceiling removes much of the old uncertainty and buys valuable time to meet relocated international orders. <\/p>\n\n\n\n<p style=\"font-size:16px\">With international buyers&#8217; ESG audit thresholds rising rather than falling, the most rational strategy is to use the host country&#8217;s tiering to take the shortest viable approval path, while relying on a mature SEZ&#8217;s infrastructure to protect high-value orders. Choosing an established zone such as MSEZ \u2014 with existing EIA authorization, a high-standard CETP and renewable-energy capacity \u2014 helps manufacturers achieve both fast setup and durable global ESG compliance.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"section-6\"><strong><strong>6. FAQ<\/strong><\/strong><\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p style=\"font-size:16px\"><strong><strong>Q1.

Compared with the full EIA (FEIA, up to 90 days) and the initial EIA (IEIA, up to 60 days), the EPA requires far less documentation \u2014 but it still requires an environmental management plan and is subject to ongoing official monitoring.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Q2. If my factory is classified as EPA, can it discharge wastewater without limits?<\/strong><\/p>\n\n\n\n<figure style=\"font-size:16px\" class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>No \u2014 this is a common and serious misconception. The EPA only simplifies the up-front approval. Once in operation, a factory&#8217;s wastewater, air emissions and industrial solid waste remain subject to Cambodia&#8217;s national environmental discharge standards, and EPA projects must still submit a quarterly or semi-annual EMR under Prakas 6985. Illegal discharge can lead to suspension, heavy fines, or criminal liability under the Law on Environmental Protection.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p><strong>Q3.
