SAFE OPERATIONS



        MSHA Citations



        The United States Department of Labor’s Mine Safety and Health Administration (MSHA) inspects each surface mine at least twice
        a year and each underground mine at least four times a year. As shown below, in the citations per inspection graph, MSHA
        conducted 728 inspections and spent 2,555 inspection days at Martin Marietta sites in 2024 and our operations were declared
        “Citation-Free” in 61% of those inspections. Our 2024 compliance performance was consistent with our strong historical
        performance as follows:

        • Citation-per-Inspection (CPI) Rate: 1.12 vs. 1.84 for the industry

        • Citations-per-Day (CPD) Rate: 0.32 vs. 1.13 for the industry.
