Evidence of Spills at Texas Toxic Site 09/19 06:06
PASADENA, Texas (AP) -- The U.S. government received reports of three spills
at one of Houston's dirtiest Superfund toxic waste sites in the days after the
drenching rains from Hurricane Harvey finally stopped. Aerial photos reviewed
by The Associated Press show dark-colored water surrounding the site as the
floods receded, flowing through Vince Bayou and into the city's ship channel.
The reported spills, which have been not publicly detailed, occurred at U.S.
Oil Recovery, a former petroleum industry waste processing plant contaminated
with a dangerous brew of cancer-causing chemicals. On Aug. 29, the day Harvey's
remnants cleared out, a county pollution control team sent photos to the
Environmental Protection Agency of three large concrete tanks flooded with
water. That led PRP Group, the company overseeing the ongoing cleanup, to call
a federal emergency hotline to report a spill affecting nearby Vince Bayou.
Over the next several days, the company reported two more spills of
potentially contaminated storm water from U.S. Oil Recovery, according to
reports and call logs obtained by the AP from the U.S. Coast Guard, which
operates the National Response Center hotline. The EPA requires that spills of
oil or hazardous substances in quantities that may be harmful to public health
or the environment be immediately reported to the 24-hour hotline when public
waterways are threatened.
The EPA has not publicly acknowledged the three spills that PRP Group
reported to the Coast Guard. The agency said an on-scene coordinator was at the
site last Wednesday and found no evidence that material had washed off the
site. The EPA says it is still assessing the scene.
The AP reported in the days after Harvey that at least seven Superfund sites
in and around Houston were underwater during the record-shattering storm.
Journalists surveyed the sites by boat, vehicle and on foot. U.S. Oil Recovery
was not one of the sites visited by AP. EPA said at the time that its personnel
had been unable to reach the sites, though they surveyed the locations using
Following AP's report, EPA has been highlighting the federal agency's
response to the flooding at Superfund sites. EPA Administrator Scott Pruitt
reiterated that safeguarding the intensely-polluted sites is among his top
priorities during a visit Friday to the San Jacinto River Waste Pits, one of
the sites AP reported about two weeks ago.
Pruitt then boarded a Coast Guard aircraft for an aerial tour of other
nearby Superfund sites flooded by Harvey, including U.S. Oil Recovery.
Photos taken Aug. 31 by the National Oceanic and Atmospheric Administration
show dark-colored water surrounding the site two days after the first spill was
reported to the government hotline. While the photos do not prove contaminated
materials leaked from U.S. Oil Recovery, they do show that as the murky
floodwaters receded, they flowed through Vince Bayou and emptied into the ship
channel leading to the San Jacinto River. The hotline caller identified Vince
Bayou as the waterway affected by a spill of unknown material in unknown
Thomas Voltaggio, a retired EPA official who oversaw Superfund cleanups and
emergency responses for more than two decades, reviewed the aerial photos,
hotline reports and other documents obtained by AP.
"It is intuitively obvious that the rains and floods of the magnitude that
occurred during Hurricane Harvey would have resulted in some level of
contamination having been released to the environment," said Voltaggio, who is
now a private consultant. "Any contamination in those tanks would likely have
entered Vince Bayou and potentially the Houston Ship Channel."
He said the amount of contaminants spread from the site during the storm
will likely never be known, making the environmental impact difficult to
measure. The Houston Ship Channel was already a polluted waterway, with Texas
state health officials warning that women of childbearing age and children
should not eat fish or crabs caught there because of contamination from dioxins
PRP Group, the corporation formed to oversee the cleanup at U.S. Oil
Recovery, said it reported the spills as legally required but said subsequent
testing of storm water remaining in the affected tanks showed it met federal
drinking water standards. The company declined to provide AP copies of those
lab reports or a list of specific chemicals for which it tested, saying the EPA
was expected to release that information soon.
U.S. Oil Recovery was shut down in 2010 after regulators determined
operations there posed an environmental threat to Vince Bayou, which flows
through the property in Pasadena. Pollution at the former hazardous waste
treatment plant is so bad that Texas prosecutors charged the company's owner,
Klaus Genssler, with five criminal felonies. The German native fled the United
States and is considered a fugitive. Genssler did not respond to efforts to
contact him last week through his social media accounts or an email account
linked to his website address.
More than 100 companies that sent hazardous materials and oily waste to U.S.
Oil Recovery for processing are now paying for the multimillion-dollar cleanup
there through a court-monitored settlement, including Baker Hughes Oilfield
Operations Inc., U.S. Steel Corp. and Dow Chemical Co.
Past sampling of materials at the site revealed high concentrations of
hazardous chemicals linked to cancer, such as benzene, ethylbenzene and
trichloroethylene. The site also potentially contains toxic heavy metals,
including mercury and arsenic.
A 2012 EPA study of the more than 500 Superfund sites across the United
States located in flood zones specifically noted the risk that floodwaters
might carry away and spread toxic materials over a wider area.
Over the past six years, remediation efforts at U.S. Oil Recovery have
focused on the northern half of the site, including demolishing contaminated
structures, removing an estimated 500 tons of sludge and hauling away more than
1,000 abandoned containers of waste.
PRP Group said the southern portion of the site, including the three waste
tanks that flooded during Harvey, has not yet been fully cleaned. Over the
years workers have removed more than 1.5 million gallons of liquid waste ---
enough to fill nearly three Olympic-sized swimming pools.
AP began asking the EPA whether contaminated material might have again
leaked from U.S. Oil Recovery last week, after reviewing the aerial photos
taken Aug. 31. The EPA said it visited the site on Sept. 4, nearly a week after
site operators reported an initial spill, and again the following week. The EPA
said that its staff saw no evidence that toxins had washed away from the scene
during either visit.
"Yesterday, an EPA On-scene coordinator conducted an inspection of Vince
Bayou to follow up on a rumor that material was offsite and did not find any
evidence of a black oily discharge or material from the U.S. Oil Recovery
site," an EPA media release said on Thursday.
PRP Group said the spills occurred at the toxic waste site on Aug. 29, Sept.
6 and Sept. 7. One of the EPA's media releases on Sept. 9, more than 11 days
after the first call was made to the hotline, made reference to overflowing
water at the scene, but did not describe it as a spill.
The company said it reported the first spill after Harvey's floodwaters
swamped the three tanks, filling them. The resulting pressure that built up in
the tanks dislodged plugs blocking a series of interconnecting pipes, causing
the second and third spills reported to the hotline the following week.
The company does not know how much material leaked from the tanks, soaking
into the soil or flowing into nearby Vince Bayou. As part of its post-storm
cleanup workers have vacuumed 63 truckloads holding about 315,000 gallons from
The Superfund site is located just a few hundred yards from the Pollution
Control Services offices for Harris County, which includes Houston. Its
director, Bob Allen, says his team took pictures of the flooding on Aug. 29,
when the area that includes the three big tanks was still underwater. The AP
requested those photos as public records, but they have not yet been released.
Allen said his staff did not note any black water or oily sheen on the
surface at the time, and did not collect water samples for testing. He said the
EPA later sampled the area to determine whether there was contamination.
"We knew that the water probably got into the plant, probably washed out
some of the stuff that was in the clarifier," Allen said, referring to one of
the old concrete tanks once used to store toxic waste. "Once they get done with
the assessment of that site and the other Superfund Harris County sites, then
they'll probably let us know, let the public know, what's been going on.
