Background
CS TAN Co., Ltd.’s leather processing factory located in Rithy I village, Kaev Pos commune, Stueng Hav district, Preah Sihanouk province, was found to have previously discharged untreated wastewater causing environmental pollution. Following amendments issued by the Ministry of Environment, the factory has been under directives to improve wastewater management to prevent environmental contamination.
Scope of Application
The measures apply specifically to the wastewater discharge systems of the leather processing factory’s production line, in particular the soaking and cleaning sections responsible for generating contaminated liquid waste. The Ministry’s environmental inspection teams monitor compliance at the factory site and natural waterways nearby.
Key Provisions or Decisions
The Ministry of Environment’s expert team has documented that the factory has undertaken corrective actions including constructing wastewater treatment ponds, achieving approximately 80% completion of these infrastructure improvements as of February 10, 2026, with plans for full completion by May 2026. Production segments identified as sources of wastewater pollution have been temporarily suspended. Inspections confirm no wastewater discharge into natural canals near the Stok pond.
Implications for Investors, Businesses, or Compliance
The case exemplifies the Ministry of Environment’s regulatory oversight in enforcing environmental protection through specific wastewater management mandates. Businesses in similar sectors are expected to comply with such environmental standards and may be subject to production suspension or infrastructure upgrades to mitigate environmental impacts. Compliance ensures alignment with environmental protection rules and contributes to sustainable industrial operation.
