On September 11, the EPA Region 7 and Iowa DNR finalized the “Work Plan Agreement” as a means to "strengthen Iowa’s implementation of the federally authorized NPDES program". You can access the final work plan agreement, information regarding desktop surveys, and standard operating procedures as well as a question and answer document on the EPA web page at: The same materials and DNR reports on workplan obligations are included on this DNR Animal Feeding Operations link.

All livestock producers, regardless of size or species, should take time to read through all of the materials available via the above links. Historically, in Iowa, when using the term "NPDES program" in context of livestock production this has referred to large livestock operations, generally speaking over 1,000 head of cattle on open lots.This agreement is structured to address livestock operations that have not been traditionally associated with NPDES permits, such as medium-sized open lots and confinement operations.

The Iowa NRCS has released their new Iowa Nutrient Management Conservation Standard, more commonly known as the 590 standard.The press release highlights the major changes in the new standard. This document is used as the basis for nutrient management planning for those farmers who choose to receive EQIP funding or technical assistance from the Iowa NRCS.

The Iowa DNR has recently updated the list of contacts for Animal Feeding Operations.

Now is a great time to make-sure your manure applicator certification status is up-to-date. Commercial manure applicators conducting business in Iowa must attend 3 hours of annual training offered at their local County Extension Office, or, must take and pass the certification exam once every year. The exams are only offered at the DNR field offices. Commercial manure applicators who have not met certification requirements yet this year must do so before they can handle, haul or land-apply manure. Confinement site manure applicators must attend 2 hours of training each year, or take and pass the certification exam once every three years. Additional information for both commercial and confinement site manure applicators can be found on the IMMAG site at, or on the DNR Web page.

Are you a commercial manure applicator business owner or manager certified in Iowa? If so, we would really appreciate if you could take a few moments to complete a survey. Please click on this link: The survey will take about 10-15 minutes. The survey will be open until October 31, 2013. Thanks in advance for your time.

The next LPELC webinar, Capturing Valuable Nutrients from Manure, is scheduled for November 15 at 1:30 p.m. (central).This webcast is the first in a series of three webcasts that will provide information on: the need to capture nutrients for recycling off-farm, global phosphorus supplies, and technologies that are being used on-farm to capture nitrogen and phosphorus from manure. These webinars are open to the public and available at no charge. Click on the link above to find instructions on how to participate the day of the webinar.

Please hold November 19 as a tentative date for a small dairy field day. ISU Extension is planning to hold a field day at the Wayne and Wade Brunsman farms near Dyersville, Iowa. The field day will look at practices and management techniques to help small dairies address potential water quality impacts. In addition, field day participants will also tour a nearby beef feedlot.  This effort is part of the Water Quality Initiatives for Small Beef and Dairy Feedlot Operations. A final date will be announced closer to November 1, and specific details will be shared on the Small Feedlot Web page at and the Iowa State Dairy Association web page at as they become available.

Iowa State University Extension, South Dakota State University, the USDA U.S. Meat Animal Research Center, and the University of Nebraska-Lincoln  are hosting a one-day beef facilities conference on November 21, 2013 at the Best Western Ramkota Hotel and Conference Center in Sioux Falls, South Dakota. This one-day conference features research and extension presentations in addition to panel discussions on management options for four different types of beef housing. Program highlights include the results of a recent air emissions study in mono-slope barns, a review of air quality regulations, capturing manure nutrients, building management and cattle performance in these types of housing facilities.
