• Provide clear, proactive project updates — including scope changes and permit timing — to stakeholders and leadership.
• Lead or support development of air permit applications, complete detailed reviews of draft permits, and recommend solutions to complex permitting issues.
• Build productive relationships with state agencies and Field Environmental Specialists to obtain permits that support business objectives.
