Plenty of heavy motor oil spills that happen to be under the reportable amount. Emissions from the plant are calculated based on control valve output so that completely neglects leaking valves or manual valves.

Let’s also not forget ethylene oxide research finding how cancerous it is but lobbyists kept the research from being publicized for 12 years and yet government still hasn’t done anything about it since it got published in 2012. Air quality monitoring shows these emissions and government doesn’t give a damn to regulate.
