Thirteen workers injured in last week’s ammonia release in Matagorda County are suing OQ Chemicals, claiming negligence and seeking damages. The contractors were working at a Bay City plant when equipment failure led to ammonia exposure. Röhm, the plant’s owner, confirmed all hospitalized workers have been released. Some were treated on-site. Officials say the release was contained quickly, and the plant remains in startup mode. The lawsuit aims to hold OQ Chemicals accountable for the incident.
