EPA has reached an agreement with the Iowa Department of Natural Resources (IDNR) to make changes to Iowa’s Clean Water Act (CWA) permit and compliance program for concentrated animal feeding operations (CAFOs). The agreement includes specific actions the IDNR intends to take to remedy the program and a timeline for implementation of those actions to ensure clean, healthy water.
“Working with states to safeguard Midwestern waters is among EPA’s highest priorities,” said Karl Brooks, EPA regional administrator. “This agreement, developed after extensive public and industry input, commits the IDNR to making needed and achievable improvements to the system that keeps CAFOs compliant with the CWA. Iowans who operate a world-class livestock sector will continue to thrive in a first-rate permitting and inspection program.”
EPA considered public comments in its assessment of IDNR’s proposed actions to ensure clean water across the state. Public comments, including feedback from the agricultural community, were taken into consideration in the drafting of the final agreement.
EPA’s investigation of Iowa’s permit and compliance program for CAFOs was carried out in response to a petition for withdrawal of the National Pollutant Discharge Elimination System (NPDES) program authorization from IDNR that was filed in 2007 by the Iowa Citizens for Community Improvement, Sierra Club and the Environmental Integrity Project. Federal regulations allow interested parties to file these petitions when they are concerned that a state is not meeting the minimum NPDES program requirements.
The IDNR has committed to:
- Change several provisions of Iowa’s CAFO rules so that Iowa state law is consistent with the federal CWA.
- Conduct a comprehensive survey of all large CAFOs and medium animal feeding operations that currently don’t have CWA wastewater discharge permits and identify those that discharge to a water of the U.S. and have failed to comply with the permit application or other Iowa requirements. Size thresholds for each species define large and medium operations. For example, operations with more than 1,000 head of cattle are defined as large and those with 300 to 999 are defined as medium.
- Review all relevant available information to evaluate site-specific factors that may signal the likelihood of a wastewater discharge to local waterways. This desktop assessment will document baseline conditions at a facility and determine whether an on-site inspection will be conducted.
- Conduct on-site inspections following agreed upon inspection procedures for all large CAFOs. For medium operations, on-site inspections will be conducted when certain site specific circumstances exist or the desktop assessment determines that an on-site inspection is needed.
- Inspect all permitted NPDES CAFOs within five years following an agreed upon inspection procedure.
- Issue timely wastewater discharge permits to all CAFOs determined to discharge to local waterways.
- Take timely and appropriate enforcement actions when needed, including assessing penalties that ensure violators do not gain competitive advantage from non-compliance.
