But the U.S. Court of Appeals for the D.C. Circuit invalidated the rule in 2008 because certain states could purchase so many allowances they wouldn't have to cut their emissions at all, defeating the purpose of the Clean Air Act. The court allowed the rule to remain in place pending a stricter replacement.
That replacement arrived in 2010, when the EPA released a draft version of its new interstate pollution reg — the Cross-State Air Pollution Rule. It still included Texas, but only in a seasonal ozone reduction program. It did, however, ask utilities and the TCEQ to comment on the potential inclusion of Texas in the sulfur dioxide program.

Sure enough, when the completed version of the rule was unveiled last July, Texas was among the states that would have to further curtail sulfur dioxide emissions. For cash-strapped Luminant, whose northeast Texas plants are responsible for nearly half of the state total, it was just another problem stacked atop a mountain.
In reality, what the rule accomplished was a level playing field. Generators like Luminant, which operated plants without the additional cost of modern pollution controls, would be forced to buy allowances from utilities that invested in cleaner plants, like Xcel Energy.
Luminant responded quickly. "Without fair notice and opportunity to comment, the EPA has mandated that Texas slash its [sulfur dioxide] by half and greatly reduce [nitrogen oxide] emissions in less than five months — an unprecedented and impossible compliance timetable. These requirements would seriously jeopardize the ability of the state's electric grid to supply power to Texas businesses and consumers and threaten the loss of hundreds of high-paying jobs."
This wasn't exactly true. The deadline for demonstrating compliance wasn't until March 2013 — at that point nearly two years away. According to an EPA statement, the 2012 date was intended to make sure pollution levels didn't spike between the lapsing of one rule and the enactment of the next. And the industry had, in fact, been given an opportunity to comment back in July 2010. The writing was already on the wall.
To expect that Texas wouldn't be included in the rule, according to one knowledgeable industry source, was "wishful thinking" at best, and shortsighted at worst.
"A lot of people put pollution controls on their plants, expecting there were going to be new environmental regulations and wanted to stay ahead of the curve," said the industry source. "Other people waited."
Nevertheless, the Texas GOP establishment registered outrage.
"The implementation of this rule will result in a loss of valuable jobs in the 4th District at Luminant, the largest power generator in Texas," said U.S. Representative Ralph Hall of Rockwall, chairman of the powerful House Committee on Science, Space and Technology. "The rule will also seriously jeopardize the ability of the state's electric grid to supply power to Texas businesses and consumers, and will have damaging effects on families and local communities whose economies depend on the success of Luminant's facilities."
The chairman of the Texas Commission on Environmental Quality, Bryan Shaw, laid out a doomsday scenario: "The rule will impose great costs on coal-fired power plants, causing some to shut down or curtail operations, threatening the state's electrical capacity reserve margins needed to avoid power disruptions during times of peak demand. Such a scenario could lead to blackouts, which create serious health risks for Texans dependent on reliable energy."
But not everyone in the industry was so pessimistic. David Knox, spokesperson for Texas wholesale power generator NRG, said, "When it comes time to meet these requirements, we will be able to meet them, and the most important thing for our employees is we don't plan any plant closures or layoffs to do that."
In fact, analyses from the financial sector and ERCOT raised doubt about claims the pollution rule would imperil the Texas grid.
Financial analysts at Bernstein Research said Luminant could meet the requirements by purchasing $15 million a year in pollution allowances. That wasn't chump change, sure, but it was a drop in the bucket compared with its debt. The truth was, during times of peak demand, Luminant wasn't running its smokestack scrubbers, installed to remove sulfur dioxide. The reason was obvious: Generators make more money during peak demand, and running scrubbers reduces the amount of power the unit produces. If Luminant left its scrubbers on all the time, Bernstein calculated, it could meet the new EPA regs without idling Monticello. In fact, Luminant would receive more allowances from the EPA in part because the agency had assumed it was running its scrubbers at full capacity in its initial calculations.
But the real question was, would it make good business sense to spend as much as $500 million on a plant Luminant said was worth only $411 million? (Luminant, for its part, says it intends to spend $1.5 billion on pollution controls by 2020, accounting for other emissions rules coming down the regulatory pike.)
Said John Rowe, chairman and CEO of Exelon Corp., one of the largest utilities in the country, to an audience at an American Enterprise Institute conference: "These regulations will not kill coal. ... In fact, modeling done on the impacts of these rules shows that up to 50 percent of retirements are due to the current economics of the plant due to natural gas and coal prices."
