December 2008 IMMAG Update

Welcome to the monthly update for the Iowa Manure Management Action Group (IMMAG) Web site. 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.

In early December the NRCS made this announcement regarding changes to the 590 Nutrient Management standard. The conservation practice standard Nutrient Management (590) has been revised to reflect the recent change in Natural Resources Conservation Service (NRCS) policy. See Iowa Bulletin No. IA180-8-6, dated July 29, 2008. NRCS policy now states that for livestock production facilities that do not have historic records, estimates of manure production and wastewater volumes will be based on the procedures found in the NRCS Agricultural Waste Management Field Handbook (AWMFH), Chapter 4. References allowing the use of Iowa State University publications for estimating manure nutrient content and volumes have been removed from the standard. Questions regarding this document should be directed to John Myers, State Resource Conservationist, at 515 323-2223 or

The IA 590 Standard can be found at:

As reported in the October 2008 edition of the IMMAG Update, earlier this year, the Iowa Legislature passed a bill that brought certain provisions of the animal feeding operations rules into compliance with the EPA's Concentrated Animal Feeding Operations (CAFO) rules. One of these provisions was the method in which animals are counted to determine if a National Pollutant Discharge Elimination System (NPDES) permit is needed. For more information regarding this rule and whether it could potentially affect your livestock operation please see The deadline for applying for these permits is December 31, 2008. If you have questions about how this may apply to your livestock facility you should call your DNR field office. In addition, DNR has introduced a proposed rule package that will address some of the concerns with this issue and meeting federal regulations. You can access that information at:

Information on the proposed rule package regarding the application of manure on snow-covered and frozen ground can be found at:

There are plenty of opportunities to make public comments regarding water quality issues in Iowa. Currently the DNR is asking Iowans to comment on the draft 2008 Iowa impaired waters list, which identifies 445 streams, rivers and lakes. The list was presented to the DNR's Environmental Protection Commission Dec. 9. The draft list and supporting materials are available on the DNR Web site. Comments can be submitted to John Olson, DNR, 502 East Ninth St., Des Moines, Iowa 50319. Or, comments can be e-mailed to

In addition, DNR is also accepting comments on proposed water quality standard rules to implement an antidegradation policy in Iowa.  

The antidegradation policy, required by Iowa law, would set minimum requirements for the state to conserve, maintain and protect water quality and existing uses of Iowa's waterbodies. People can also submit written comments by sending them to Adam Schnieders, Iowa DNR, 502 East 9th St. , Des Moines, IA 50319, or by e-mail to The DNR will accept comments until January 29, 2009. For more information, including a list of public hearings and view the complete rule proposal, click here.
