Workshops Provide Environmental Issues Update for Medium-Sized Beef Feedlots and Dairies

AMES, Iowa — Iowa State University Extension will offer four workshops in northeastern and eastern Iowa featuring environmental issues for feedlots and dairies that are medium-sized concentrated animal feeding operations (CAFOs).

The workshop schedule is as follows:

  • June 27 — Northeast Iowa Dairy Foundation Center in Calmar
  • June 28 — Country Junction Restaurant in Dyersville
  • June 29 — Buzzy’s Restaurant in Welton
  • June 30 — Moose Lodge in Charles City 

All workshops will run from 10 a.m. to 3 p.m. 

“Medium CAFOs are defined by a combination of size and pollutant discharge conditions,” said Angie Rieck-Hinz, ISU Extension program specialist. “If you meet the size threshold, you are defined as a CAFO if you discharge pollutants to waters of the U.S. by direct contact of the animals with the waters or by discharging through a man-made ditch, flushing system or similar man-made device.”

Each workshop will cover the following topics: definition of a medium-sized CAFO; National Pollutant Discharge Elimination System (NPDES) permit requirements; design criteria for manure and effluent handling and storage; operation, maintenance and nutrient management plans; and resources for technical and financial assistance.

Staff from the Iowa Department of Natural Resources will present information on the permitting process and Iowa regulations. Consultants and companies from Iowa and surrounding states are sponsors for the workshops and will be available to discuss engineering services, manure plans and technical assistance.

Registration for the workshop is $30 for individuals and the first person from each livestock operation and $15 for each additional person from the same livestock operation.
