KUALA LUMPUR: A leak from a storage tank at an acrylic processing plant in Kampung Orang Asli, Kuang, in Rawang, has been identified as the cause of the pollution that temporarily shut down the Rantau Panjang Water Treatment Plant in Sungai Selangor.
Natural Resources and Environment Minister, Nik Nazmi Nik Ahmad, said the Department of Environment identified the cause of the pollution as a chemical leak from a storage tank containing Poly-Methacrylic Acid (PMAA). The chemical is a clear, colourless liquid with a pungent odour.
"The leak resulted in the release of the odour, due to the distinctive characteristics of PMAA. As a result, the DoE immediately issued instructions to the operator to clean up the mess within the premises and at the affected drains and tributaries. These operations have been completed," he said in a statement today.
Nik Nazmi said three samples were collected and submitted to the Chemistry Department for composition testing, and matching.
"All processing equipment at the facility was seized by the DoE upon the issuance of a Suspension of Operations Notice under Section 38(1)(a) of the Environmental Quality Act 1974, pending the completion of investigations," he added.
He said the department also initiated legal action, and confirmed the arrest of two individuals to assist in investigations. The case is being investigated under Section 25 of the Environmental Quality Act 1974 (Amendment 2024).
He said the government takes environmental crimes seriously, as reflected in the Environmental Quality Act (Amendment) 2024, which imposes mandatory imprisonment of up to five years, and a maximum fine of RM10 million for river pollution offences.
"Businesses must play a crucial role in ensuring that their factories or operations comply with all environmental legislation, and do not cause environmental pollution," he said.
He urged members of the public to provide information to the authorities, including the DoE, regarding activities that could harm the environment.
