(a) EEOC determination of jurisdiction. Upon receipt of a charge of employment discrimination, the EEOC shall:

(1) Determine whether it has jurisdiction over the charge under title I of the ADA. If it has jurisdiction, except as provided in paragraph (b)(2) of this section, the EEOC shall process the charge pursuant to title I procedures.

(2) If the EEOC determines that it does not have jurisdiction under title I, the EEOC shall promptly refer the charge to the Civil Rights Division. The Civil Rights Division shall determine if a Federal agency may have jurisdiction over the charge under section 504 or title II, and, if so, shall refer the charge to a section 504 agency or to a designated agency with jurisdiction over the complaint.

(b) Retention by the EEOC for investigation. (1) The EEOC shall retain a charge for investigation when it determines that it has jurisdiction over the charge under title I.

(2) Referral to an agency. Any charge retained by the EEOC for investigation and processing will be investigated and processed under title I only, and will not be deemed dual filed under section 504, except that ADA cause charges (as defined in 29 CFR 1601.21) that also fall within the jurisdiction of a section 504 agency and that the EEOC (or the Civil Rights Division, if such a charge is against a government, governmental agency, or political subdivision) has declined to litigate shall be referred to the appropriate section 504 agency for review of the file and any administrative or other action deemed appropriate under section 504. Such charges shall be deemed complaints, dual filed under section 504, solely for the purposes of the agency review and action described in this paragraph. The date of such dual filing shall be deemed to be the date the complaint was received by the EEOC.
