(a) Designated agency processing. A designated agency shall investigate and process a complaint that has been filed with it and with the EEOC, a section 504 agency, or both, when either of the following conditions is met:

(1) The designated agency determines that it has jurisdiction over the complaint under title II and that neither the EEOC nor a section 504 agency (other than the designated agency, if the designated agency is also a section 504 agency) has jurisdiction over the complaint; or

(2) The designated agency determines that it has jurisdiction over the complaint under section 504 and the complaint meets the requirements for processing by a section 504 agency set forth in § 1640.8(a)(2).

(b) Referral by a designated agency. A designated agency that has jurisdiction over a complaint solely under title II (and not under section 504) shall forward a complaint that has been filed with it and with the EEOC, a section 504 agency, or both, to either the EEOC or to a section 504 agency, as follows:

(1) If the designated agency determines that the EEOC is the sole agency, other than the designated agency, with jurisdiction over the complaint, the designated agency shall forward the complaint to the EEOC for processing under title I; or

(2) If the designated agency determines that the section 504 agency is the sole agency, other than the designated agency, with jurisdiction over the complaint, the designated agency shall forward the complaint to the section 504 agency for processing under section 504; or

(3) If the designated agency determines that both the EEOC and a section 504 agency have jurisdiction over the complaint, the designated agency shall forward the complaint to the EEOC if it determines that the complaint solely alleges employment discrimination against an individual, or it shall forward the complaint to the section 504 agency if it determines that the complaint meets the requirements for processing by a section 504 agency set out in § 1640.8(a)(2)(i) or (a)(2)(ii).
