Refineries Belch Tons of Pollution During Texas Blackout

By Amy Lupica, ODP Staff Writer

Despite over four million Texans losing power during the recent deep freeze, oil refineries released an increased amount of pollution into the air. In a state that leads the nation in both power production and carbon emissions, experts say that failure to winterize power infrastructure resulted in harmful releases of toxic air pollution. The excess emissions produced during the freeze were caused by controlled flares that were needed to prevent damage to gas processing units.  Jane Williams, chair of the Sierra Club’s National Clean Air Team, told Reuters that “these emissions can dwarf the usual emissions of the refineries by orders of magnitude.”

Why This Matters: Texas is the nation’s leading power producer, and to achieve this, the state has heavily deregulated not only its power grid but the fossil fuel industry as well. As of 2016, Texas was producing 653 million metric tons of carbon emissions every year, almost twice that of the next highest, California. The consequences of these emissions impact air quality across the state, but primarily impact communities of color and poor communities that often live near refineries. Those affected have reported symptoms from asthma to neurological issues, and experts say that communities plagued by low air quality may even be at a higher risk of severe COVID-19. 

By the Numbers

Many refineries were forced to perform these controlled burns to protect their existing, (and flawed) infrastructure, leading to a disastrous spike in emissions that darkened skies in east Texas. According to the Texas Commission on Environment Quality (TCEQ), toxins released into the atmosphere included benzene, carbon monoxide, hydrogen sulfide, and sulfur dioxide.

  • The five largest refineries released 337,000 pounds of pollutants.
  • Valero Energy Corp reported that it released 78,000 pounds over 24 hours.
  • Motiva’s Port Arthur refinery reported 118,100 pounds of excess emissions, more than three times the amount reported for the entire year of 2019.
  • Marathon Petroleum Corp’s MPC.N Galveston Bay Refinery reported releasing 14,255 pounds of pollutants in just 5 hours.
  • Exxon Mobil Corp reported that its Baytown Olefins Plant released nearly one ton of benzene and 68,000 tons of carbon monoxide.

These burns are harmful, but they wouldn’t have been necessary had the state winterized its infrastructure as it was advised to in 2011.  

Blissful Ignorance

Most of the state operates on its own privatized power grid which is managed by a single company, the Electric Reliability Council of Texas (ERCOT). After facing similarly devastating deep freezes in 1989 and 2011, several national organizations came together to advise ERCOT on how best to winterize its infrastructure, but despite encouraging private energy providers to upgrade, ERCOT never made the changes mandatory. This time, over two dozen people died in relation to the freeze, and poor communities and communities of color were left with no power or water while richer, whiter communities stayed warm with the lights on. All the while, conservative pundits and politicians blamed renewable energy, completely ignoring the real reasons they found themselves in this crisis: an overreliance on natural gas and a failure to learn from past mistakes.

Study Finds That Half of All Methane Emissions Come from Aquatic Ecosystems

By Amy Lupica, ODP Staff Writer A new paper published Monday in the journal Nature Geoscience found that up to half of the global methane emissions come from aquatic ecosystems and man-made water sources like flooded agricultural land, ponds, wetlands, reservoirs, and salt marshes. Experts say that these emissions have gone uncounted for too long […]

Biden’s Ambitious New Rail Plan Expands Service Map To New Cities

Right now, Las Vegas, Nashville, and Phoenix all don’t have Amtrak service. That could change if the new Amtrak service map, released last week as part of President Biden’s infrastructure plan, gets built.

Why This Matters: Getting around by train is more energy-efficient than driving or flying, especially if it’s electrified.
