NEW DELHI (AP) — India's capital has been choking under a thick layer of smog this month, the worst the air quality has been all year in a city that's among the most polluted in the world. While some people work indoors and get a measure of relief from the pollution during the day, others in the city of more than 17 million aren't so fortunate.

The Allegheny County Health Department's new proposed pollution limits at Allegheny Technology Inc.'s specialty steel plant in Harrison threaten public health, according to four environmental groups.

But the health department, which regulates ATI's air emissions, disagrees.

Environmentalists say ATI's new air pollution limits are about 36 percent higher than the ones proposed last year in a draft operating permit.
