      <strong>The heart of Texas' oil refining industry was hit by
      Hurricane Harvey</strong>
    </p>
  </li>
  <li>
    <strong>Storm-related flooding overwhelmed existing safety
    precautions at many plants</strong>
    <strong>, releasing hundreds
    of thousands of pounds of chemicals</strong>
  </li>
  <li>
    <strong>4.6 million pounds of chemicals were released overall,
    some of which are cancer-causing</strong>
  </li>
  <li>
    <strong>While advocates expressed concern about potential
    health effects, federal and state representatives said there is
    littleÂ reason for alarm</strong>
  </li>
</ul><p>
  Hurricane HarveyÂ <a href="http://www.businessinsider.com/hurricane-harvey-impact-texas-oil-refineries-2017-8">struck
  the heart</a> of Texas' oil refining industry when it pummeled
  Houston last week, resulting in the release of 4.6 million pounds
  of chemicals.
</p><p>
  Those chemicals include cancer-causing and potentially lethal
  gases like carbon monoxide and benzene, among others.
</p><p>
  But public health advocates and state and federal
  regulatorsÂ are split aboutÂ whether or not people should
  worry. While anÂ EPA representativeÂ <a href="https://www.nytimes.com/interactive/2017/09/08/us/houston-hurricane-harvey-harzardous-chemicals.html?mcubz=3">told
  the New York Times</a>Â that residents âshould not be
  concerned about air quality issues related to the effects of the
  storm,â environmental advocates have said the opposite.
</p><p>
  âThese are cancer-causing compounds, like benzene and butadiene,â
  Elena Craft, an Environmental Defense Fund senior health
  scientist, told the Times. âWeâre very concerned about peopleâs
  long-term health in the area.â
</p><p><a href="http://engineering.ucmerced.edu/content/wei-chun-chin">Wei-Chun
  Chin</a>, a professor of engineering at the University of
  California, Merced, has conductedÂ research on the
  after-effects of oil spills like Deepwater Horizon. He told
  Business Insider in August that although the immediate effects of
  the pollutants in Texas sounded concerning, he wasÂ more
  worried about the possibility thatÂ some of those chemicals
  mightÂ stick around.
</p><p>
  "Iâm more concerned about things that could have a lingering
  effect and stay in the soil," said Chin. "Benzene is a known
  carcinogen. So if that's coming back into the ground that would
  be very bad."

  The Texas Commission on Environmental Quality, the state's
  pollutant-monitoring agency, <a href="https://www.epa.gov/newsreleases/epatceqcity-houston-harvey-update">
  said in a statement</a>Â that most of its air-surveying
  equipment didÂ not detect emissions at levels that would be
  harmful to human health. Yet on September 5, Houston officials
  said they had detected high levels of benzeneÂ near one of
  the refineries that wasÂ damaged by the storm.Â Loren
  Raun, the chief environmental science officer for the Houston
  Health Department, <a href="https://www.nytimes.com/interactive/2017/09/08/us/houston-hurricane-harvey-harzardous-chemicals.html">
  told the Times</a>Â that although the readings varied,
  officials in the area were seeing âhigh numbers.âÂ 
</p><p>
  <span>The EPA isÂ working with Texas state regulators to
  clean up spillsÂ from a dozen industrial facilities, but
  representatives said itÂ was still too earlyÂ to estimate
  the amounts spilled, the <a href="http://www.businessinsider.com/r-us-coast-guard-epa-cleaning-up-a-dozen-texas-chemical-spills-after-harvey-2017-9">
  Associated Press</a>Â reported.</span>
</p><h2>
  Harvey's rising waters overwhelmed existing safety precautions
</h2><p>
  Shortly after Harvey made landfall, companies including <a href="http://markets.businessinsider.com/stock/xom-Quote">Exxon
  Mobil</a> and <a href="http://markets.businessinsider.com/stock/vlo-Quote">Valero
  Energy</a> began to shutter local facilities and evacuate
  workers, taking <a href="http://www.businessinsider.com/hurricane-harvey-impact-texas-oil-refineries-2017-8">
  close to a fifth of the nation's total refining capacity</a>
  offline.
</p><p>
  Yet in many cases, those efforts failed to prevent the release of
  hazardous pollutants into the environment.

  Preliminary reports</a>Â severely underestimated the scope of
  theÂ leaks, pegging the figure at somewhere around 2 million
  pounds. A more recentÂ analysis â fromÂ the Environmental
  Defense Fund, Air Alliance Houston, and Public Citizen
  âÂ suggests the number is closer to 5 million.
</p><p>
  In some cases, companies intentionally burned chemicals to
  dispose of them in anticipation of the storm. This type of burn,
  called a chemical flare,Â is a means ofÂ relieving
  pressure on a plant during a shutdown and is considered standard
  industry practice, <a href="https://www.americanchemistry.com/Media/PressReleasesTranscripts/ACC-news-releases/Statement-By-ACC-President-and-CEO-Cal-Dooley-in-Response-to-Hurricane-Harvey.html">
  according to the American Chemistry Council</a>.
</p><p>
  Chevron Phillips, the company thatÂ <a href="http://www2.tceq.texas.gov/oce/eer/index.cfm?fuseaction=main.getDetails&amp;target=266261">reported
  the largest release</a>, burned close to 800,000 pounds of
  chemicals as it shuttered its plant to prepare for Harvey. The
  colorless, odorless, and <a href="https://www.cdc.gov/co/faqs.htm">potentially deadly gas carbon
  monoxide</a>Â made up nearly 300,000 pounds of that total.
</p><p>
  At other plants, <a href="http://www.businessinsider.com/hurricane-harvey-floodwater-dangerous-tetanus-2017-8">
  Harvey's rising waters</a> easily overwhelmed existing safety
  precautions.
</p><p>
  San Antonio-based refiner Valero Energy toldÂ local
  regulators that a floating roof covering a tank at its Houston
  refinery sank on August 27 due toÂ Harvey-related flooding,
  and benzene subsequently leaked into the air. Similarly,
  officials at Kinder Morgan's Pasadena terminal, which released
  close to 300,000 pounds of chemicals, <a href="http://www2.tceq.texas.gov/oce/eer/index.cfm?fuseaction=main.getDetails&amp;target=266269">
  noted in a filing</a> that several floating roof tanks were
  "impacted by torrential downpour" from Harvey.Â 
</p><p>
  Â At Exxon's Baytown plant, the floating roof covering one
  tank also "partially sank during the <a href="http://www.businessinsider.com/harvey-rain-rainfall-break-record-2017-8">
  excess rain event</a>". The companyÂ <a href="http://www2.tceq.texas.gov/oce/eer/index.cfm?fuseaction=main.getDetails&amp;target=266294">noted
  the issue in a filing</a>Â that showed that close to 13,000
  pounds of chemicals â including <a href="http://www.who.int/ipcs/features/benzene.pdf">cancer-causing
  benzene</a> and toxic lung-irritant xylene â
  wereÂ released.Â 
</p><p>
  <span>Charlotte Huffaker, a representativeÂ for Exxon Mobile,
  told Business Insider that the company "reported and responded"
  to theÂ partially submergedÂ tank "as soon as it was
  identified," and said the containerÂ was currently stable and
  secure.Â </span>
</p><p>
  Still, these impacts may have lingering health effects.
</p><p>
  Last week, testing done in the Manchester district near the
  Valero refinery reveledÂ <a href="https://www.nytimes.com/2017/09/06/us/harvey-houston-valero-benzene.html?rref=collection%2Fsectioncollection%2Fhealth&amp;action=click&amp;contentCollection=health&amp;region=stream&amp;module=stream_unit&amp;version=latest&amp;contentPlacement=8&amp;pgtype=sectionfront">high
  levels of the cancer-causing pollutant benzene</a>, the Times
  reported.Â The sampling showed concentrations of up to 324
  parts per billion of benzene, which isÂ aboveÂ <a href="https://www.atsdr.cdc.gov/ToxProfiles/tp3-c1-b.pdf">the
  level</a>Â at which federal safety officials
  suggestÂ workers use special breathing equipment.
</p><p>
  ValeroÂ did not immediately respond to a request for comment.
