Cabinet approved a 7.2 billion baht dam project on August 5, 2026, in Chanthaburi to serve EEC and irrigate 87,700 rai, citing a 13.18% economic return and 2.20 B/C ratio. However, government communication omits environmental costs: forest area within Khao Sip Ha Chan National Park will be submerged. The Seub Nakhasathien Foundation questions the incomplete disclosure and notes the project still requires National Park Board deselection approval. The foundation previously filed an administrative court case (dismissed July 15) and plans to appeal, citing flawed environmental impact assessment data.
