This update is provided as a service to inform you about changes made to the IMMAG Web Page or items of interest dealing with manure management and air quality from animal feeding operations.

CURRENT NEWS: The Current News page on the IMMAG site is updated weekly. Please check this site often for the latest news regarding animal feeding operations and manure management issues.

The Iowa Pork Producers Association still has hang tags available. STOP Manure Agitation and Pump–Out in Progress tags are designed to hang on facility doors during manure pump-out and agitation. These tags are being made available to Iowa pork producers and commercial manure applicators. These tags are designed to limit confusion and increase employee and family safety. Please remember that no one should enter a confinement site building or manure storage structure when agitation and pump-out is taking place. To request tags, please contact Tyler Bettin, IPPA Producer Education Director by calling (515) 225-7675 or email

Fall manure application season is right around the corner. Are you prepared? Read the IMMAG Top Ten List, PREPARING FOR FALL MANURE APPLICATION. Remember  manure spills or releases need to be reported as soon as possible or no later than 6 hours after onset or discovery to the 24-hr Reporting Number (515) 281-8694. Each fall millions of gallons of manure are safely applied in Iowa.  Keep up the great work! Do you have a specific practice you employ or a practice you train your employees to implement in manure spill response? If so, send me a brief paragraph and a high quality digital photo and I will compile a list of your ideas/suggestions and share it with IMMAG readers.

PUBLICATIONS AND REPORTS: Texas A&M University has just released the publication "Improving the Air Quality of Animal Feeding Operations with Proper Facility and Manure Management". This publication is available by visiting the Texas AgriLife Bookstore online at: and typing the reference number E-585 in the search function.

MANURE APPLICATOR CERTIFICATION: School has or is starting, family vacations are over and crop harvest is a few weeks away, so now is a great time to meet your annual manure applicator certification requirements. Confinement site manure applicators need to attend 2 hours of training annually to meet their certification requirements. Commercial manure applicators are required to attend 3 hours of annual training. Commercial applicators are allowed to work for 30 days prior to meeting certification requirements but must be working toward certification and must be supervised by a certified commercial manure applicator. The supervisor must be physically present at the application site and be in sight and able to communicate with the employee at all times.

Please contact your County Extension Office to schedule time to meet the required annual training or contact your local DNR Field Office to schedule time to take the certification exam.  If you need to determine you current certification status, contact the DNR Licensing Bureau at 515-281-5918. Please ask for the Licensing Bureau and state you are a manure applicator. Additional information can be found on the ISU Manure Applicator Certification Web Page at:  or on the DNR’s Web page at:
