Lung Association says Pittsburgh air better but not good
The Pittsburgh region had its best-ever air quality last year, but still was one of two places outside California to rank among the 25 most polluted in the American Lung Association's “State of the Air 2013” report.
Allegheny County trimmed its average of unhealthy air days to 20.7 from 26.3 in the 2012 report, but still earned an overall F grade. Several counties improved their grades with Armstrong and Beaver improving from an F to a C, Washington County improving from a D to a C and Lawrence County improving from a C to a B.
The association's methodology produces critics every year because of its selectivity. The report uses only the worst daily readings from federal monitors. For the Pittsburgh region, that means most readings come from Liberty, a small Mon Valley town about 16 miles southeast of the Golden Triangle that lies downwind of U.S. Steel Corp.'s Clairton Coke Works, the nation's largest coke plant.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.
While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.
We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers.
We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.
We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.
We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.
We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
