Position Summary: The Director of Environmental provides strategic and operational leadership for all environmental compliance, stewardship, and sustainability activities across Atalco's integrated bauxite-to-alumina value chain. The role holds single-point accountability for environmental performance at two geographically and jurisdictionally distinct operations: the Gramercy alumina refinery in Louisiana, United States, and the St. Ann bauxite mining operation in Jamaica. Reporting to senior leadership, the Director sets environmental policy and standards, ensures full compliance with all applicable United States federal and Louisiana state regulations as well as Jamaican national environmental and mining law, and drives a proactive culture of environmental risk management, continuous improvement, and responsible resource stewardship. The role is central to protecting Atalco's license to operate, managing all permitting, exploration, alumina processing, bauxite residue and mined-land liabilities, safeguarding air, water, and land resources, and maintaining constructive relationships with regulators, communities, and other stakeholders in both countries. Scope of Operations Gramercy Alumina Refinery — Gramercy, Louisiana, USAA Bayer-process alumina refinery on the Mississippi River that converts imported bauxite into smelter- and chemical-grade aluminas. Key environmental features and risk areas include Title V air emissions sources (calcination, digestion, power/steam generation), process and stormwater discharges to the Mississippi River under a Louisiana water discharge permit, bauxite residue (red mud) storage and management areas, caustic and chemical handling, spill prevention, and hazardous and industrial waste management within a densely regulated US industrial corridor. This scope is expanding to cover gallium extraction from the Gramercy Bayer process, as well as potentially the beneficiation of critical minerals and other elements from the bauxite residue. St. Ann Bauxite Operation — St. Ann Parish, Jamaica An open-pit bauxite mining, drying, and export operation set in Jamaica's karst limestone terrain. Key environmental features and risk areas include permitting, exploration, sensitive specie preservation and relocation, land clearing and progressive mine development, mined-land reclamation and restoration, dust and air quality management from mining, trucking, railing, and drying, material handling/conveying, ship loading, protection of groundwater and surface water resources, biodiversity and reforestation obligations, haul-road and shipping-terminal impacts, and management of overburden and red-earth materials—all governed by Jamaican environmental permits, licenses, and mining lease conditions.

Key Responsibilities: Environmental Strategy & Leadership Define and own the environmental strategy, policy, standards, permits, and related management systems that apply consistently across both operations while respecting each jurisdiction's legal requirements. Establish a single, harmonized environmental management framework (aligned to ISO 14001 principles) that sets a common standard of performance while accommodating US and Jamaican regulatory differences.

Embed environmental accountability into operational decision-making, capital planning, and site leadership performance objectives. Regulatory Compliance — Gramercy (United States) Ensure full and continuous compliance with all applicable US federal and Louisiana state environmental requirements, including the Clean Air Act, Clean Water Act, Resource Conservation and Recovery Act (RCRA), and Emergency Planning and Community Right-to-Know Act (EPCRA).Own the site's Title V air operating permit, Louisiana water discharge (LPDES) permit, and all related permits, ensuring conditions, monitoring, and reporting obligations are met. Maintain compliant relationships and correspondence with the US Environmental Protection Agency (EPA), Louisiana Department of Environmental Quality (LDEQ) and applicable local agencies. Oversee Toxic Release Inventory (TRI / Form R), Tier II, greenhouse gas, and other mandated federal and state reporting.

Manage environmental permit and license applications, renewals, Environmental Impact Assessments (EIAs), environmental permit conditions, and related matters for mine exploration, development and expansion. Ensure compliance with mined-land reclamation, restoration, and post-mining land-use obligations under Jamaican law and lease commitments. Bauxite Residue, Waste & Materials Management Direct the safe management, processing, monitoring, and long-term stewardship of bauxite residue (red mud) storage areas at Gramercy, including structural integrity, seepage control, water balance, and closure planning. Oversee management of overburden, red-earth, tailings, and process waste materials at St. Ann in line with permit conditions and reclamation plans. Ensure hazardous, industrial, and general waste is characterized, stored, transported, and disposed of in compliance with applicable regulations at both sites. Air, Water, Land & Biodiversity Oversee air emissions monitoring, control, and dust management across refining from bauxite discharging through to final product loading (Gramercy) and mining/drying/shipping (St. Ann) activities. Manage water resources, process water, wastewater, and stormwater programs, including discharge monitoring, groundwater and surface-water protection, and water quality reporting. Lead progressive mined-land reclamation, revegetation, reforestation, and biodiversity protection programs at St. Ann, and land stewardship and site remediation at Gramercy. Permitting, Monitoring & Reporting Own the full lifecycle of environmental permits, licenses, and authorizations at both operations—applications, renewals, modifications, and condition tracking. Ensure timely, accurate, and defensible environmental monitoring, recordkeeping, and regulatory reporting in both jurisdictions. Maintain an audit-ready compliance calendar and documentation system spanning both sites. Incident Management & Emergency Response Establish and maintain environmental incident prevention, spill response, and emergency preparedness programs at both operations. Lead environmental incident investigations, root-cause analysis, corrective action, and regulatory notification and follow-up.
