AUGUSTA — Attorney General William Schneider is asking state Department of Environmental Protection Commissioner Darryl Brown for additional documents to prove that he does not have a conflict of interest.

“In the absence of new information, it appears you are unqualified to serve as Commissioner of the Department of Environmental Protection under Maine law,” Schneider said in a statement.

Brown’s personal attorney Clint Boothby wrote letters to Schneider and the U.S. Environmental Protection Agency because of questions surrounding Brown’s income from Main-land Development Consultants in the period before he became commissioner.

Boothy “expresses concern about potential damage to Main-land Development’s business interests from the public disclosure of its client list and revenue information, and questions whether such records would become part of the public domain if submitted to the Attorney General’s Office for its review,” according to the Attorney General’s Office.

Schneider said those records would be subject to public review.

He also advises that “if he has a conflict, as suggested by Mr. Boothby, Mr. Brown would be precluded from serving as Commissioner of the Department of Environmental Protection under Maine statute.”
