SJV in autumntime: 2nd of two lulls between heightened episodes of fine PM, smog

There is a chill in the air. The smog in it – the air – is fading. Not because of diminishing daylight but, presumably, on account of lower ambient levels of heat.

At long last, a curbing-air-pollutant-emissions-and-greenhouse-gases focus

Will railroad, neighbor settle diesel-emissions-related dispute? Time will tell

There is a to-do astir, a dust-up if you prefer, in Pennsylvania’s Kutztown borough.
