Previous Work

Before joining ArentFox Schiff, Amy was an assistant attorney for the Illinois Pollution Control Board. Amy advised board members on interpretations of Illinois environmental statutes and regulations. A former adviser to the Illinois Pollution Control Board, Amy understands the ins and outs of the multitude of matters falling under the Board’s jurisdiction. Because Amy served as a hearing officer, she knows how to make her clients’ perspectives heard—and often favorably acted upon. She also served as a hearing officer in regulatory matters and drafted legal opinions in quasi-adjudicatory enforcement cases, permit appeals, and requests for relief from Illinois environmental laws.

Earlier in her career, Amy served as assistant counsel for the Illinois House of Representatives, where she drafted legislation, interacted with various stakeholders and lobbyists, and advised representatives on proposed legislation. Now, when her clients’ site-specific situations clearly fall outside the rules, Amy seizes the opportunity, working quickly and creatively under pressure to craft site-specific new rule proposals. Many of those rules have been adopted and, more importantly, have helped her clients sidestep the costly standstill of regulatory non-compliance.
