The Trump administration has been an ally to the energy industry, promising “energy dominance” from the campaign trail to the recent rollback of unnecessary regulations. But its latest move—tariffs imposed on imported steel and aluminum—is proving problematic for the industry.

In a March 2018 letter to President Trump, nine trade associations including GPA Midstream warned the president of the tariffs’ negative impacts. “We fear that broad tariffs on the specialty steels used by our industry would cause future projects to be delayed or canceled, thus threatening America’s energy dominance and risking higher prices for families at the gas pump, natural gas ratepayers and energy-consuming employers nationwide,” it warned.
