Dive Summary:

• The Dallas County Medical Society has petitioned the Texas Commission on Environmental Quality to mandate three coal-fired plants owned by Luminant in East Texas to curtail emissions they say are causing toxic ozone levels in North Texas.
• Luminant, a subsidiary of Energy Future Holdings, said the doctors’ claims are “wrong and misleading” and attributed 90% of nitrogen oxide pollution to vehicles and airplanes. "[B]laming the real cause doesn't fit with these activists' narrow agenda of trying to close coal plants and force Texans to pay higher costs for their electric power from less reliable sources," Luminant said.
• The physicians are worried for citizens' health as research suggests that high ozone levels caused by emissions increase the risk of premature death.

From the article:

“The study said the three plants account for nearly half the sulfur dioxide emissions by Texas power plants, many of which have improved their emissions in the past decade. As of 2012 the plants' sulfur dioxide emissions were more than double that of all other old coal-fired plants per megawatt-hour of electricity generated, and about four times that of the 10 cleanest old coal plants.”
