Back in September, the Texas chapter of the environmental group, the Sierra Club, said it had done its own analysis of pollution data from the Parish Power Plant. The huge plant burns tons of coal a day. It’s owned by NRG and sits on the southern edge of the booming suburb of Sugar Land.
The Sierra Club said data showed air pollution from the plant was exceeding government health standards for sulfur dioxide. NRG disagreed.
Now, two months later, the Sierra Club suggests in emails to News 88.7 that some of the data it used may have been incorrectly entered into a computer model and that their results may have overstated the impact of sulfur dioxide emissions. However, the group said it still believes the plant is in violation of government safeguards.
NRG had no official comment.
But it and the Sierra Club have each been submitting their own research to the U.S. Environmental Protection Agency. It’s in the process of tightening limits on sulfur dioxide and is looking at how much a plant like Parish should be allowed to emit.
