The Iowa Administrative Code (IAC) contains several chapters regulating the direct discharge of wastewater to waters of the state. The chapters containing most of the wastewater permit regulations are as follows:
Rules regarding NPDES permits for Animal Feeding Operations (Chapter 65) can be found on the
Animal Feeding Operations page. Rules regarding onsite (private) wastewater systems (Chapters 68, 69, and 93) can be found on the Private Septic Systems page. The Water Quality Standards (Chapter 61) can be found on the Water Quality Standards page.
The chapters above are regularly updated through the state's rulemaking process. Please refer to the Current NPDES Rulemaking Actions section below for more information on any proposed rule changes.

Wastewater Cleanup Rulemaking:
Disadvantaged Community Rule: The disadvantaged community rule proposed in 2012 became effective on January 16, 2013. This rule implements Iowa Code 455B.199B, as modified by Senate File 407 (SF407). The code section and senate file establish criteria that DNR must use to determine if ratepayers or a community will experience substantial and widespread economic and social impact and qualify as disadvantaged as a result of complying with wastewater regulations. Please see the Rural Community Sewers page for more information on the disadvantaged community rule. For more information regarding the disadvantaged community rule and on how to qualify for disadvantaged status, please contact Courtney Cswercko at firstname.lastname@example.org.
