Trump Exempts Scores of Plants From Biden’s Pollution Rules

President Donald Trump is allowing chemical makers, coal-fired power plants and other facilities to bypass a range of environmental regulations on grounds that the waivers are needed for national security purposes.

The plants, which also include taconite iron ore processing operations and chemical manufacturing facilities that play a role in the production of semiconductors and energy, were granted two-year waivers from Environmental Protection Agency rules via proclamations signed by Trump and released on Thursday evening. The rules were finalized under the Biden administration.
