Okla. Admin. Code § 660:2-7-1
Investigations may be initiated upon inquiry, request or complaint by members of the public or by the Administrator or the Commission upon their own motion. The request or complaint by a member of the public should be in writing on the form identified in Chapter 6 of this Title, be signed by the complainant and contain a statement setting forth the acts, activities or matters and the name and address of the party or parties against whom they are complaining. No formal procedures are required in making such requests or complaints. The complainant is not regarded as a party, since the Administrator acts only in the public interest. The Administrator shall not take action when the acts, activities or matters complained of are merely matters of private controversy and do not tend to adversely affect the public.
