The Environmental Protection Agency has completed one of its last major rollbacks under the Trump administration, changing how it considers evidence of harm from pollutants in a way that opponents say could cripple future public-health regulation.EPA Administrator Andrew Wheeler is expected to formally announce completion of what he calls the “Strengthening Transparency in Regulatory Science” rule in an appearance before a conservative think tank on Tuesday.
The EPA completed the final rule last week, but so far has declined to make the text public.The new rule would require the release of raw data from public-health studies whose findings the EPA uses in determining the danger of an air pollutant, toxic chemical or other threat.
