The restart of ExxonMobil’s Torrance refinery narrowly received regulatory approval Saturday after a South Coast Air Quality Management District Hearing Board (AQMD) voted 3-2 to allow it to reopen after a daylong hearing at City Hall, the Los Angeles Daily News reports. The plant was shuttered after a February 2015 explosion. The agency also imposed a fine of about $5 million in for air pollution violations as a result of the explosion and for violations that could occur during the startup of the refinery.
