TITLE 327 WATER POLLUTION CONTROL DIVISION

Amends 327 IAC 20 concerning updates to the United States Department of Agriculture (USDA) Natural Resource Conservation Service (NRCS) Conservation Practice Standards for consistency with the requirements found in 327 IAC 19. Effective 30 days after filing with the Publisher.

Findings and Determination of the Commissioner Pursuant to IC 13-14-9-7 and Second Notice of Comment Period: February 10, 2021, Indiana Register (DIN: 20210210-IR-327210028FDA).

Notice of Public Hearing: February 10, 2021, Indiana Register (DIN: 20210210-IR-327210028PHA).

Date of First Hearing: May 12, 2021.

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 10, 2021, at DIN: 20210210-IR-327210028FDA, the Indiana Department of Environmental Management (IDEM) is not requesting additional comment on this proposed rule.

IDEM requested public comment from February 10, 2021, through March 12, 2021, on IDEM's draft rule language. No comments were received during the second comment period.

On May 12, 2021, the Environmental Rules Board (board) conducted the first public hearing/board meeting concerning the development of amendments to 327 IAC 20. No comments were made at the first hearing.
