The Senate Environment and Public Works Committee will host a hearing on April 11 to consider the nomination of current Environmental Protection Agency (EPA) Assistant Administrator for Air and Radiation Gina McCarthy to be EPA Administrator. While she will likely be confirmed, Senate Republicans are expected to question McCarthy on agency transparency, air standards for industrial boilers, greenhouse gas emission standards, hydraulic fracturing, national ambient air quality standards, and sulfur in gasoline. Sen. John Barrasso (R-WY), an Environment and Public Works Committee member, has said he considered placing a hold on the nomination.
