Fall manure application is in full-swing in Iowa and that requires us to remind you about safety practices when pumping manure as well as taking extra precautions when transporting manure.  Please take a few moments to review the information in this press release and to train and remind family members and employees about these practices related to pumping liquid manure. Caution Urged when Pumping Manure from Deep Pits.

Get plenty of rest, take breaks and slow down. Observe all laws of the road and watch out for the "other driver". They may not realize you are moving at a much slower rate of speed or how long your tractor and tank wagon are when they attempt to pass you on the road. Check “slow moving vehicle signs” and replace as needed. Check lights to make sure they are working and are visible. Install additional lights as needed to improve your visibility and to help people see you. Make sure employees and family members meet manure applicator certification requirements and are well trained to handle various situations. Take time to train new employees and refresh the memory of experienced employees.

The Environmental Protection Commission, a panel of nine Iowa citizens who provide policy oversight regarding Iowa’s environmental protection efforts, is meeting on October 16 in Des Moines.  One of the agenda items for the meeting will be the EPC's final decision on the pending ban of liquid manure application to soybeans.  You can find information on this topic by viewing EPC agenda link and then in the left column of the pdf file, click on bookmark 5 to find the supporting information regarding this topic.  Or, the information pertaining to this topic starts on page 4 and continues through page 129.

In other news, the Environmental Protection Agency (EPA) Region 7 is taking public comments on Iowa DNR’s response to the EPA report on CAFO permitting and compliance program.   Written comments must be sent by email to or mailed and postmarked on or before Oct. 17, 2012, to Stephen Pollard, Water Enforcement Branch, EPA Region 7, 901 N. 5th Street, Kansas City, KS 66101.

Action on this issue is summarized as follows. 

  • In September 2007, several environmental groups filed a petition with EPA saying Iowa DNR’s implementation of the NPDES permitting program did not comply with the Clean Water Act and asked EPA to withdraw Iowa DNR’s authority of the program. 
  • In July 2012, the EPA issued a report into its investigation of the allegations.
  • In September 2012 the Iowa DNR responded to EPA’s report.

You can access to EPA’s investigation and report to DNR and DNR’s response on this web page:

As part of the "Water Quality Initiatives for Small Iowa Beef and Dairy Operations", commonly known as the small feedlot project,  Iowa State University is hosting two field days at the end of October.  The purpose of these field days is to review low-cost options for managing runoff water and manure from small to medium size beef and dairy feedlot operations. 

Oct. 29 Wall Lake field day
The first field day will be on Monday, Oct. 29 from 10:30 a.m. to noon at the Bob Ziegmann farm located near Wall Lake. This field day will feature a system designed to keep manure runoff out of the road ditch and distribute it in a crop field instead. The Ziegmann feedlot is located at 3740 B Ave., Wall Lake, Iowa. To get to the feedlot from Wall Lake, go south 5 miles on M64 and then 2.5 miles west on B Ave. 

Oct. 31 Andover field day
The second field day will be on Wednesday, Oct. 31 from 10:30 a.m. to noon at the Ray and Andrew Naeve feedlot located west of Andover. This field day will look at two different kinds of manure handling systems. One is an earthen basin located below one feedlot that provides protection to a nearby stream. The other is a concrete settling basin adjacent to a feedlot that captures manure runoff and settles the manure solids with the effluent discharged to cropland.
The Naeve feedlot is located at 4166 135th St., Clinton, Iowa. To reach the feedlot go 0.5 miles north of the intersection of County Hwy E50 and Z50 on County Hwy Z50 (thru Andover) to 135th Street. Turn left (west) on 135th Street and go 1.6 miles to first place on north side of road. Lunch will be served by the Clinton County Cattlemen’s Association.

Both field days will be held rain or shine. In addition to the manure control systems, the field days will also include information on regulations for small and medium sized feedlots, nutrient content of feedlot manure and use in cropping systems, manure stockpiling regulations, and financial and technical assistance opportunities for feedlot owners.

This initiative is supported by the Iowa State Dairy Association, Iowa Department of Natural Resources, Iowa Cattlemen’s Association, Iowa Department of Ag and Land Stewardship, USDA-NRCS, and Iowa State University Extension and Outreach, and is supported in part by a section 319 grant from the IDNR and U.S. Environmental Protection Agency, Region 7. More information is available in the events list below.


Any commercial manure applicator who was certified in 2011 and has not yet attended training or taken the certification exam, must meet certification requirements prior to any manure application work this fall.  Because that person was certified in the previous year, there is no 30-day exemption for training. 

Any new, never been certified before, commercial manure applicators may handle, haul, or land-apply manure for the first 30 days of employment without being certified, but they must be working toward their certification requirements.  Do not delay.  Some Extension offices have pre-set days of the month for training commercial and confinement site applicators.  Call you County Extension office to determine training dates or to make an appointment to watch the training video.

Confinement site applicators should plan to attend the required 2 hours of annual training by contacting their County Extension office to determine the training schedule or to make an appointment to view the training video.  Confinement site applicators are required to attend 2 hours of training each year to maintain their 3-year license.  If you miss a year of training during your three-year certification period, you will be required to take and pass the remedial exam prior to renewing your next certificate. 

If training does not work in your schedule, you may contact a DNR Field Office to schedule an appointment to take the certification exam.
