Rensselaer County residents are being invited to a town hall-style meeting on air quality issues at the Lafarge cement plant located across the Hudson River, according to local press.

Lafarge officials will present their findings on its recent voluntary emissions tests conducted last year, along with an update on its efforts to modernize its facility in Ravena.

The Lafarge Cement Plant was categorized by the Environmental Protection Agency in 2007 as the nation’s fourth worst mercury polluter for its toxic air emissions.

Rensselaer County lawmakers had expressed concern over emissions from southern Albany County migrating across the Hudson River to southern Rensselaer County.
