IDNR COVID-19 Enforcement and Compliance Protocol

IDNR has issued a compliance and enforcement protocol in response to the current COVID-19 pandemic. The protocol is to provide regulatory relief and alleviate the economic effects of businesses and key state facilities closings. IDNR will exercise enforcement discretion through April 30, 2020 by, (1) not seeking administrative penalties for cited violations, or by (2) renewing or not seeking to revoke certain licenses, certifications or permits. The protocol addresses key concerns and annual reporting extensions for solid waste, animal feeding operations, air quality, stormwater, IDNR certified time of transfer program, wastewater, and water supply programs. If you would like to discuss the protocol with us, please reach out to either our Burlington, IA or West Des Moines, IA offices.
