Circuit and practiced environmental law at Sidley Austin in Washington, D.C.

Recent administrative experience includes:

  • Lesley and a team of Liskow lawyers obtained a decision in favor of South Louisiana Methanol LP (“SLM”) in the appeal of air quality permit modifications by a group of environmental petitioners.

The permits authorize construction of what would be the largest methanol plant in the world.
