Water Quality Bureau Rulemaking

General Information - Executive Order 10

Executive Order 10 (EO10) signed by the Governor on January 10, 2023, requires all state agencies to identify which administrative rule chapters will be retained or rescinded. The EO10 process for both the review of existing rule chapters and the reauthorization of rule chapters that will be retained includes public engagement with the opportunity for meaningful input throughout the process. During the Water Quality Bureau's implementation of EO10, opportunities for public input and information for public review will be posted on this webpage as they become available.

WQB Rulemaking Schedule, News & Meetings

Anticipated Rulemaking Schedule and General Chapter Information

The WQB currently manages 31 rule chapters, all of which are in 567 (Environmental Protection Commission) of the Iowa Administrative Code (IAC). For ease of review, the Bureau’s chapters have been placed into groups by topic. The current and proposed rule documents, EO10 materials, and staff contacts for each group are listed below.

The Regulatory Analyses for the EO10 rule revisions for all of the WQB chapters except Chapter 9 were published in the Iowa Administrative Bulletin on 9/4/2024, and the Notices of Intended Action (NOIAs) were published in the Bulletin on 1/8/2025. Two public hearings were held for each of the chapters in January and February of 2025. 

The final rules Chapters 39, 49, 82, 50, 53, 54, 55, 60, 62, 63, 67, 68, 81, 83, and 90 were presented to the Environmental Protection Commission (EPC) at their meeting in April. The new rules and rescissions for these chapters will become effective on June 18, 2025. 

The final rules for chapters 40,41, 43, and 69 will be presented to the commission in June or July.

Public Hearings, Meetings & Comments

This section will be updated as new meetings are scheduled. Direct comments and questions on the proposed rules to the contact(s) listed in each Group.

Delegation of Construction Permitting Authority, Chapter 9

This group contains Chapter 9, which was the department’s delegation of construction permitting authority to local systems. The rule was intended to provide a framework for the water supply and wastewater extension delegated authority program in Iowa Code 455B.183. However, in practice, the rule effectively mirrored the Code. Since there was no reason to have the language in two places, we rescinded this chapter, effective June 19, 2024.

Wells, Chapters 38, 39, 49, & 82

This group contains the chapters regarding private water well construction permits (38), properly plugging abandoned wells (39), nonpublic water supply wells (49), and well contractor certification (82).
