Republicans on Friday said a Government Accountability Office (GAO) report proved their claims that a pair of environmental rules would harm the economy and electric reliability.

The GAO report released Thursday touched on two forthcoming Environmental Protection Agency (EPA) regulations that have drawn criticism from Republicans. Though the report said complying with those rules would pose “reliability challenges,” it maintained those risks were avoidable.

GOP staff from two committees saw the final report differently. They said the report points to glaring problems their members have long identified as significant risks to electric reliability and costs.
