Three Prachin Buri factories were ordered to suspend operations after suspected toxic chemical leaks polluted floodwater. Authorities will first order improvements under Factory Act Section 37 and move to closure under Section 39 if firms do not comply. Officials want higher fines and treating illegal industrial waste dumping as a financial crime that allows asset seizure. Investigators are also checking nominee shareholding and financial links at two companies with 400 million baht combined registered capital. For factory owners in flood-hit eastern provinces, check waste handling and permits now, and expect tighter enforcement and penalties if the amendments pass.
