   1. (i) A copy of the water quality certification;
   2. (ii) A copy of the request for certification, including proof of the date on which the certifying agency received the request; or
   3. (iii) Evidence of waiver of water quality certification as described in paragraph (b)(5)(2) of this Section.
2. (2) A certifying agency is deemed to have waived the certification requirements of section 401(a)(1) of the Clean Water Act if the certifying agency has not denied or granted certification by one year after the date the certifying agency received a written request for certification. If a certifying agency denies certification, the applicant must file a copy of the denial within 30 days after the applicant received it.
