• Maintain all environmental permits and records (Air, Water, Reclamation). Ensure the site remains in 100% compliance with local, state, and federal laws.
• Oversee the daily crushing, washing, and screening operations. Design and adjust plant flows to maximize Tons Per Hour (TPH) and minimize downtime.
• Develop and execute short- and long-term mining plans, including stripping, reclamation, and pit development.
• Collaborate with the QC department to ensure all products meet ASTM and DOT specifications. Investigate and resolve any material quality complaints immediately.
• Manage the plant’s operating budget, focusing on cost-per-ton reduction and efficiency improvements.
• Assist in the development of Capital Expenditure (CAPEX) requests and oversee the installation of new equipment or facility upgrades.
• Manage stockpiles and end-of-month inventory reporting; coordinate with Sales to ensure product availability matches market demand.
• Implement and manage a robust PM program for all fixed and mobile equipment to ensure maximum mechanical availability.
• Plan and execute major plant shutdowns for repairs, ensuring projects are completed safely, on time, and within budget.
• Directly supervise, coach, and mentor a team of production supervisors, lead persons, and hourly staff.
• Conduct annual performance reviews, identify training needs, and manage labor relations.
• Act as the primary face of Martin Marietta for the local community, neighboring landowners, and regulatory inspectors.
