Any person subjected to unlawful practice or conduct in violation of this Division may file with the Director a complaint in writing. The complaint shall state the name and address of the person alleged to have committed the violation complained of and the particulars thereof, but the Director may relax this requirement for illiteracy or for other good cause. Upon filing a complaint as set forth in this Section, the Director shall make such investigation as it deems appropriate to ascertain facts and issues. If the Director shall determine that there are reasonable grounds to believe a violation has occurred and is susceptible of conciliation, the Director shall attempt to conciliate the matter by methods of initial conference and persuasion with all interested parties and such representatives as the parties may choose to assist them. Conciliation conferences shall be informal. Nothing said or done during such initial conferences shall be made public by the Director or any member of the staff of the Department of the Environment unless the parties agree thereto in writing.
