February 2007 IMMAG Update

Welcome to the monthly electronic 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. If you wish to receive this mailing or have your name removed from the mailing list please contact me at (515) 294-9590 or You may also view this update with direct links on the CURRENT NEWS site on IMMAG.

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.  

IMMAG Fact: In 2006, the IMMAG Web page had 149,162 visitors, up from 74,904 in 2005.

Recent News from DNR:
OPEN FEEDLOT MANUAL AVAILABLE. Producers who need a construction permit for an open feedlot will want to check out the Open Feedlot Construction Permit Manual. The manual was developed to help speed the application process and allow producers who use the new process to receive a construction permit within 60 days or less. A pre-application meeting between the producer(s), consultant(s) and the DNR is the biggest change in the process.  Generally, producers need a construction permit if they need a National Pollutant Discharge Elimination System (NPDES) permit, and plan to construct or expand their open feedlot or its run-off handling system. Less than 10 percent of the 1600 open feedlots registered with the DNR have needed construction permits. Some of those dropped below 1,000 animal units, but would need a construction permit and an NPDES permit if they expand to 1,000 animal units and discharge to a stream at any time.  Some feedlots, such as medium and designated CAFOs, need an NPDES permit even if they have less than 1,000 animal units. There is no fee to apply for an open feedlot construction permit. The manual includes an updated version of the Open Feedlot Construction Permit Application form (542- 1427), which was updated in January 2007.

FORM FOR NPDES PERMITS REVISED. An updated version of the Application for Individual NPDES Operation Permit (542-4001) has been posted on the forms page of the DNR Web site. The form was revised in January of 2007 and should be used by producers who are required to have a National Pollutant Discharge Elimination System permit (NPDES). According to state and federal law, all large CAFOs (generally those animal feeding operations with 1,000 or more animal units) who discharge to a stream at any time are required to have an NPDES permit. Iowa open feedlots need carefully consider if their facility discharges or has the potential to discharge at any time in deciding if they need to have an NPDES permit. If a large CAFO does not have an NPDES permit it would be a violation of state and federal law to discharge to a stream under any circumstances even if the open feedlot did not anticipate a discharge. Medium CAFOs (generally, 300 to 1,000 animal units) may also be required to have an NPDES permit. And, smaller operations may be required to have an NPDES permit if the DNR determines they are a designated CAFO. More information is available on the U.S. EPA Web site.

DNR FORM FOR NUTRIENT MANAGEMENT PLAN IS NOW AVAILABLE. The DNR has developed a nutrient management plan (NMP) form, primarily for the convenient use of open feedlot and other producers required to have an NPDES permit. The Nutrient Management Plan form is available on the forms page of the DNR Web site. Producers who must have an NPDES permit or have more than 1000 animal units on open lots are required to have an NMP. However, producers who apply for cost-share through the Environmental Quality Incentives Program (EQIP) are required to have a comprehensive nutrient management plan (CNMP) – available through the Natural Resources Conservation Service.

SMALL ADDITION MADE TO MMP FORM. The DNR has added a category for the status of an operation on page 1 of the manure management plan (MMP) form (542-4000) for an "existing operation, new owner." The new addition should help avoid confusion about whether or not indemnity fees are due.

And finally, the DNR reports that counties have finalized their resolutions to adopt and implement the Master Matrix.  A map showing the list of counties that have adopted the Master Matrix for 2007 can be found at: For more information on the Master Matrix, please see

SERVICE PROVIDERS: The manure plan writers and engineering consultants lists were updated this past week. Producers who need to file manure management plans are encouraged to seek help in developing their plans. Due to the complexity of the software program RUSLE2 which is used in calculating soil loss for the Phosphorus Index, which subsequently is used to determine if you will apply manure based on nitrogen or phosphorus, please do not wait until the last moment to complete your manure management plan.  You need to prepare for your P Index plan several months in advance by making sure you meet soil sampling requirements and can provide all of the necessary field information for use in the software.  A list of manure plan writers can be found on the Service Providers section of the IMMAG site.  This list currently contains 42 businesses or individuals who offer services to develop manure management plans. You can access the manure plan writers list directly at:

MANURE APPLICATOR CERTIFICATION:  All confinement site applicators renewing their 3 year licenses and all commercial manure applicators are reminded they have until March 1 to submit their forms and fees to DNR to renew their licenses without the penalty of the late fee.  If you have not yet met your certification requirements, you should contact your county extension office to schedule an appointment to watch the training videos or contact your DNR field office to make an appointment to take the certification exam. 

If you are one of the 230 confinement site applicators who missed one or more of the annual training requirements for the Manure Applicator Certification Program, you should have received a letter from DNR stating your need to take the remedial certification exam.  You need to take this exam and meet certification requirements before you apply any manure.  Please see for additional information.


Dry Poultry Manure Applicator Workshops.  There are 3 remaining dry poultry manure applicator certification workshops scheduled in February.  These workshops will meet the certification requirements for both commercial manure applicators and confinement site manure applicators.  Workshops will be held on:
February 20, at the Washington County Extension Office, 9 a.m. to noon;
February 23, at the Heartland Museum, Clarion, 9 a.m. to noon; and
February 26,  at the Branding Iron Restaurant, Thompson, 9 a.m. to noon.
