• Coordinate with regulatory agencies, clients, consultants, and internal project teams to move projects through permitting and approval processes.
• Analyze field data, identify project impacts and benefits, site regulatory constraints, and permitting requirements to support project decisions.
• Review and interpret maps, design plans, drawings, technical reports, and project documents.
• Develop schedules, communicate expectations, and coordinate timely completion of regulatory deliverables.
