IC 13-14-9-4.5 states that a board may not adopt a rule under IC 13-14-9 that is substantively different from the draft rule published under IC 13-14-9-4, until the board has conducted a third comment period that is at least 21 days long.

Because this proposed rule is not substantively different from the draft rule published on February 12, 2020, at DIN: 20200212-IR-326190082SNA, the Indiana Department of Environmental Management (IDEM) is not requesting additional comment on this proposed rule.

IDEM requested public comment from February 12, 2020, through March 13, 2020, on IDEM's draft rule language. No comments were received during the second comment period.

On November 18, 2020, the Environmental Rules Board (board) conducted the first public hearing/board meeting concerning the development of amendments to 326 IAC 6.5-6-31. No comments were made at the first hearing.
