On behalf of the over 400 members of the National Stone, Sand & Gravel Association (NSSGA), I am writing to express our opposition to the proposed Placitas Withdrawal, that would permanently ban future aggregate production in areas of central New Mexico, severely limiting critical resources needed in the construction of infrastructure and public works projects for this growing region. NSSGA represents aggregates producers and those who manufacture equipment and services that support the construction industry. Aggregates, such as sand, gravel, and crushed stone, are the bedrock of our infrastructure, providing the essential components for roads, bridges, wind farms, water treatment facilities, as well as residential and commercial buildings. The current proposal by the Bureau of Land Management (BLM) to withdraw 4,212.98 acres of land in New Mexico from mining and related activities raises significant concerns. This land is not only situated near the Albuquerque market, but it also harbors some of the region's only accessible aggregate supplies
