# 124.17 Response to comments.

(a) (*Applicable to State programs, see 40 CFR 123.25 (NPDES), 145.11 (UIC), and 271.14 (RCRA).*)At the time that any final permit decision is issued under § 124.15, the Director shall issue a response to comments. States are only required to issue a response to comments when a final permit is issued. This response shall:

(1) Specify which provisions, if any, of the draft permit have been changed in the final permit decision, and the reasons for the change; and

(2) Briefly describe and respond to all significant comments on the draft permit raised during the public comment period, or during any hearing.

(b) For EPA-issued permits, any documents cited in the response to comments shall be included in the administrative record for the final permit decision as defined in § 124.18. If new points are raised or new material supplied during the public comment period, EPA may document its response to those matters by adding new materials to the administrative record.

[48 FR 14264, Apr. 1, 1983, as amended at 89 FR 103501, Dec. 18, 2024]
