Water Quality Rulemaking

General Information - Executive Order 10

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.

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 Notice of Intended Action to rescind Chapter 9 was presented to the Environmental Protection Commission at their meeting on October 17, 2023.
