Water Quality Rulemaking

General Information

Executive Order 10 - Background

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on January 10, 2023, requires all state agencies to identify which administrative rule chapters will be retained or rescinded.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 rules and the reauthorization of retained rules includes public engagement throughout the process. Opportunities for public input and information for public review during the Water Quality Bureau's implementation of EO10 will be posted on this webpage as they become available.

WQB Rules Grouped by Topic

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 nine groups by topic. Each group and its corresponding chapters are listed below. To view the current and proposed rule documents, EO10 materials, and staff contacts for each group, please use the links below.

Quick Links to Groups with Posted Rules:

Group 1 - Chapter 9
Group 2 - Chapters 38, 39, 49, & 82
Group 3 - Chapters 40, 41, 42, & 43
Group 4 - Chapters 50 to 55
Groups 5 and 6 - Chapters 60, 62, 63, 64, 66, and 67, and the IWFDS
Group 7 - Chapters 68 and 69
Group 8- Chapters 81 and 83, Operator Certification and Laboratory Certification
Group 9 - Chapters 90 to 93 & 44, Clean Water and Drinking Water SRF

Group 1 - Delegation of Construction Permitting Authority, Chapter 9

Short Summary: Group 1 contains Chapter 9, which is the department’s delegation of construction permitting authority to Local Systems. The intended benefit of the rule was 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 is no reason to have that language in two places, we are proposing to rescind this chapter. The rescinded version of Chapter 9 was effective on June 19, 2024.

Chapter 9 Rule Documents:

Group 2 - Wells, Chapters 38, 39, 49, and 82

Short Summary: Group 2 contains Chapters 38 (Private Water Well Construction Permits), Chapter 39 (Requirements for Properly Plugging Abandoned Wells), Chapter 49 (Nonpublic Water Supply Wells), and Chapter 82 (Well Contractor Certification). We are proposing to revise Chapters 39 and 82, and combine Chapters 38 and 49 in to one chapter, a new Chapter 49.
