Alex Mills is a company man. He heads the largest state oil and gas association in the United States. He’s based in Wichita Falls, 90 minutes northwest of the Azle-Reno area, where a series of earthquakes hit six months ago. This story is part of our series on “What’s Behind the North Texas Quakes?”

As president of the Texas Alliance of Energy Producers, Alex Mills represents businesses in nearly 30 states. In a weekly column, he wrote that hydraulic fracturing has become a focal point of attack for many environmental groups that want to deter or ban oil and natural gas production.

“The issue with hydraulic fracturing is not really an issue,” Mills said. “Because hydraulic fracturing is a process that has proven to be safe and reliable to get hydro-carbons out of the ground, oil and natural gas.”

He says officials from a number of federal agencies, including the Environmental Protection Agency, agree that fracturing is safe.

In response, Oklahoma Insurance Commissioner John Doak advised Oklahomans to buy earthquake insurance.
