Notice of Intended Action

Proposing rule making related to general permits

and providing an opportunity for public comment

The Environmental Protection Commission (Commission) hereby proposes to amend Chapter 64, "Wastewater Construction and Operation Permits," Iowa Administrative Code.

Legal Authority for Rule Making

This rule making is proposed under the authority provided in Iowa Code section 455B.173(11).

State or Federal Law Implemented

This rule making implements, in whole or in part, Iowa Code sections 455B.173(11), 455B.183 and 455B.186.

Purpose and Summary

This proposed rule making renews five National Pollutant Discharge Elimination System (NPDES) general permits (General Permit Nos.5, 6, 7, 8, and 9). General permits authorize certain types or classes of facilities to discharge wastewater without having to obtain an individual NPDES permit. General permits are required by law to be adopted through rule making.

The proposed renewal of all five permits in one rule making will streamline future renewals by aligning the permits' respective effective dates. The effective dates for all five general permits will be July 1, 2023, through June 30, 2028.

This rule making includes proposed changes to General Permit Nos.5 through 7 to align the permits with recently revised definitions in 567—Chapter 60. More substantive changes are made to General Permit Nos.8 and 9. This is the first renewal for these two permits. The changes to both of these permits are necessary to clarify and revise regulatory requirements. Among other updates, the changes clarify requirements for electronic Notice of Intent submittals, extend applicable time frames, and insert consistent terminology. Further changes to General Permit No.8 add eligibility criteria for ammonia and update the eligibility criteria for lead and aluminum.

The proposed permits can be viewed in full at

Fiscal Impact

This rule making has no fiscal impact to the State of Iowa. A copy of the fiscal impact statement is available from the Department of Natural Resources (Department) upon request.

Jobs Impact

After analysis and review of this rule making, no impact on jobs has been found. A copy of the jobs impact statement is available from the Department upon request.
