Arlington Heights, IL., August 31

CETCO, a wholly owned environmental business subsidiary of AMCOL International Corp. (NYSE:ACO), today announced the rollout of its new CETCO-Lining Technologies Engineering Website, www.cetco.com/lte.

The new site provides engineers with an updated version of all technical references, as well as standard references.
