Al Armendariz was appointed to the head EPA region 6 in 2009 by President Barack Obama. It was a speech he made two years ago that led to his resignation over the weekend. In the videotaped remarks, Armendariz used Roman crucifixion as an example of how big oil and gas companies had to be dealt with to set an example for the rest of the industry.
Ken Kramer is head of the Sierra Club in Texas and says Armendariz will be missed.
"He was really moving aggressively to try to help clean up the air in major Texas cities like in the Houston-Galveston area and I think it's unfortunate that he resigned because there's not going to be that personal commitment there on the part of an individual to really move us forward to try to clean-up our air."
Sugar Land Republican Congressman Pete Olson says he applauds the resignation and that Armendariz and the EPA have had it out for energy industry in Texas.
"To have an administrator who was so hostile to domestic energy production, basically wanting to keep our dependence on foreign source of energy so he can pursue his own personal agenda is just flat wrong. He represents the people of Region 6, not some personal agenda."
Armendariz has been replaced on an interim basis in Region 6 by EPA veteran Samuel Coleman.
