(a) Within 180 days of the receipt of a complete complaint, the Official shall complete the investigation of the complaint, attempt informal resolution, and if no informal resolution is achieved, issue a letter of findings. The 180-day time limit may be extended with the permission of the Assistant Attorney General. The investigation should include, where appropriate, a review of the practices and policies that led to the filing of the complaint, and other circumstances under which the possible noncompliance with this part occurred.

(d) If a complaint is resolved informally, the terms of the agreement shall be reduced to writing and signed by the complainant and respondent. The agreement shall be made part of the complaint file with a copy of the agreement provided to the complainant and the respondent. The written agreement may include a finding on the issue of discrimination and shall describe any corrective action to which the complainant and the respondent have agreed.

(e) The written agreement shall remain in effect until all corrective actions to which the complainant and the respondent have agreed upon have been completed. The complainant may reopen the complaint in the event that the agreement is not carried out.
