Researchers from UC San Diego and their partners found that the W.A.
Parish coal plant is the largest producer of cloud-forming particles in the greater Houston region.
In a statement, NRG Energy, which owns the power plant, said it is evaluating the study.
The researchers are part of the Experiment of Sea Breeze Convection, Aerosols, Precipitation, and Environment (ESCAPE) campaign.
The team is studying how pollution is impacting atmospheric heating and cooling patterns that lead to cloud formation.
Greg Roberts, an atmospheric scientist with UC San Diego's Scripps Institution of Oceanography, helped lead the study.
"Obviously Houston itself has many different sources of pollution," he said.
"It could be vehicular traffic.
It’s obviously refineries, the power plants, cooking fires — these kinds of things — and in any urban environment you will see those sorts of pollution."
Roberts said the Houston area is surrounded by both the Gulf Coast and rural areas with low air pollution, which provide a baseline for comparing pollution impacts.
His research team flew an airplane with research tools from the National Research Council of Canada around the greater Houston area to study the effects of pollution on cloud formation.
"It became very clear that the particles coming from the refineries ... are very small aerosol particles on the orders of 10 nanometers or so or less," Roberts said.
"And they were not activating at all into cloud droplets."
Like the refineries, the Parish coal plant produces volatile organic compounds.
However, Roberts said the coal plant also produces sulfur dioxide — which he said accelerates particle growth.
"A combination of the size and the chemistry then enables these particles to serve as seeds for clouds,"
he said.
Roberts said these particles are between 30 and 50 nanometers in size.
"It also yields these particles that tend to penetrate the deepest into lungs, which has a big effect for understanding the health impacts that this power plant could imply on the population," he said.
In a statement about the study, NRG reiterated its commitment to meeting regulatory standards.
"We are aware of the study and reviewing its findings," a spokesperson said.
"Houston's air environment includes many sources, and this excerpt/article reflects one piece of a broader picture.
What we can speak to is how we operate: meeting all local, state and federal regulatory standards with controls and significant monitoring in place.
We support regulations grounded in sound science that ensure/uphold the safe, reliable, and affordable production of electricity, and we work closely with regulators and local communities to uphold those standards."
Local advocates have called for the coal plant's closure for several years, citing research about potential health impacts from its emissions.
