Since 1956, CSSGA has championed Colorado’s aggregate industry through advocacy, sustainability, and infrastructure support.
Our Mission is Impact-Driven
CSSGA advocates for Colorado’s aggregate industry through education, safety, and public policy. In partnership with the Mine Safety Institute (MSI), we promote responsible operations and long-term sustainability.
We're Committee-Run and Community-Led
