An application for amendment of a license for a water power project must contain the following information in the form specified.
  1. (a)Initial statement.
  2. (b)Required exhibits for capacity related amendments. Any application to amend a license for a hydropower project that involves additional capacity not previously authorized, and that would increase the actual or proposed total installed capacity of the project, would result in an increase in the maximum hydraulic capacity of the project of 15 percent or more, and would result in an increase in the installed name-plate capacity of 2 megawatts or more, must contain the following exhibits, or revisions or additions to any exhibits on file, commensurate with the scope of the licensed project:
    1. (1)For amendment of a license for a water power project that, at the time the application is filed, is not constructed and is proposed to have a total installed generating capacity of more than 10 MW—Exhibits A, B, C, D, E, F, and G under § 4.41;
    2. (2)For amendment of a license for a water power project that, at the time the application is filed, is not constructed and is proposed to have a total installed generating capacity of 1.5 MW or less—Exhibits E, F, and G under § 4.61 of this chapter;
    3. (3)For amendment of a license for a water power project that, at the time the application is filed, is not constructed and is proposed to have a total installed generating capacity of 10 MW or less, but more than 1.5 MW—Exhibits F and G under § 4.61, and Exhibit E under § 4.41;
    4. (4)For amendment of a license for a water power project that, at the time the application for amendment is filed, has been constructed, and is proposed to have a total installed generating capacity of 10 MW or less—Exhibit E, F, and G under § 4.61; and
    5. (5)For amendment of a license for a water power project that, at the time the application is filed, has been constructed and is proposed to have a total installed generating capacity of more than 10 MW—Exhibits A, B, C, D, E, F, and G under § 4.51.
  3. (c)Required exhibits for non-capacity related amendments. Any application to amend a license for a water power project that would not be a capacity related amendment as described in paragraph (b) of this section must contain those exhibits that require revision in light of the nature of the proposed amendments.
  4. (d)Consultation and waiver.
    1. (1)If an applicant for license amendment under this subpart believes that any exhibit required under paragraph (b) of this section is inappropriate with respect to the particular amendment of license sought by the applicant, a petition for waiver of the requirement to submit such exhibit may be submitted to the Commission under § 385.207 of this chapter, after consultation with the Commission's Division of Hydropower Compliance and Administration.
    2. (2)A licensee wishing to file an application for amendment of license under this section may seek advice from the Commission staff regarding which exhibits(s) must be submitted and whether the proposed amendment is consistent with the scope of the existing licensed project.
  5. (e)For any amendment that requires certification under section 401(a)(1) of the Federal Water Pollution Control Act (Clean Water Act), a certifying authority is deemed to have waived the certification requirements of section 401(a)(1) of the Clean Water Act if the certifying authority has not denied, expressly waived, or granted certification by one year after the date the certifying authority received a written request for certification.
