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

CSSGA’s work is driven by its members. Through active committees focused on safety, regulation, outreach, and advocacy, we unite industry voices to shape smart policy, share best practices, and strengthen Colorado’s aggregate community.

Why Membership Matters

Membership provides producers, suppliers, and small businesses with advocacy support, safety resources, and a strong industry network working toward a sustainable future.
