The U.S. government imposed tougher standards on smog-producing ozone in a far-reaching clampdown that will affect everything from factories to power plants, and which industry groups said will cost jobs.
The U.S. Environmental Protection Agency tightened nationwide limits on concentrations of ground-level ozone, the main component of smog, to 70 parts per billion, from 75. The EPA’s standard falls at the weaker end of the range of 65-70 parts per billion that the agency proposed in November.
