Vice President, Senior Chemical Engineer

Profile Picture

Lori oversees large, complex air-quality-permitting and environmental-management projects for mining and other industrial clients. Her 25-year background encompasses:

  • Environmental review and Environmental Impact Statements (including EISs prepared in compliance with NEPA) 
  • Air emissions permitting
  • Dispersion modeling
  • Stack testing
  • Compliance with federal air-quality regulations including PSD, NSR, NSPS, MACT, BACT, Title V, SARA Title III, and the Clean Air Act

Lori’s recent work includes serving as principal in charge of environmental approvals for the Essar Steel Minnesota project, which comprises iron ore mining, taconite production, direct-reduced-iron processing, and a steel mill. She led the preparation of successful applications for multiple environmental permits, including a PSD air permit and a permit to mine. She also led the preparation of an Environmental Assessment Worksheet and a state and federal Environmental Impact Statement that included cumulative-impact studies for air, including particulates, acid deposition, mercury, and visibility.

In addition, Lori served as principal in charge of environmental approvals for U. S. Steel’s Keetac expansion project in Minnesota, for which the final EIS was recently approved.
