A Brief History and Background of the EPA CAFO Rule
U.S. Environmental Protection Agency (EPA) rules affecting animal feeding operations (AFOs) have evolved from the 1972 Federal Clean Water Act (CWA). Section 502 of the CWA specifically defined “feedlots” as “point sources” along with dozens of other industries such as meat processing and fertilizer manufacturing. The goal of the 1972 CWA was to restore “fishable, swimmable” quality of lakes, streams, and estuaries in the United States.
A federal permit program termed the National Pollutant Discharge Elimination System (NPDES) was created for point sources that discharged into “waters of the United …

Alternative Treatment Systems
The February 13, 2003 Federal Register revised the Environmental Protection Agency’s (EPA’s) “Part 412-Concentrated Animal Feeding Operations (CAFO) Point Source Category,” which described the revised Effluent Limitations Guidelines (ELG) and New Source Performance Standards (NSPS) for concentrated animal feeding operations (CAFOs). The regulation applies to manure, litter, and/or process wastewater discharges resulting from CAFOs. Subpart C addresses dairy cows and cattle other than veal calves, which includes dairy operations and beef cattle feedlots. Subpart D addresses swine, poultry, and veal calves. Baseline ELGs in the revised rule prohibit discharge of process waste waters except when rainfall events …

New BSE Rule Will Change Re-Feeding of Poultry Litter to Ruminants
The Food and Drug Administration announced on January 26, 2004 several new public health measures, to be implemented, to strengthen significantly the multiple existing firewalls that protect Americans from exposure to the agent thought to cause bovine spongiform encephalopathy (BSE, also known as mad cow disease) and that help prevent the spread of BSE in U.S. cattle. One of those changes will impact how re-feeding of waste to animals is allowed.
To implement these new protections, FDA will publish two interim final rules that will take effect immediately upon …

The Value of Manure for Crop Production
Manure has value for crop production when it provides nutrients or soil amendments needed for optimal crop yields. Crop producers can in many cases justify paying animal feeding operations to apply manure to their land. A recent extension publication “Calculating the Value of Manure for Crop Production

Rural Development Through Pork Production: The Nebraska Model
Nebraska’s producers of pork are striving to create systems of production that are environmentally, economically & socially acceptable.
This is no small challenge. While attempting to comply with environmental rules, producers are faced with the rules changing as they implement adoption. Social acceptance varies with locale but is generally less positive than in the past. And, Fewer operations have livestock and fewer people in the rural population rely on livestock for their livelihoods—which makes any livestock production operation less acceptable.
The issues facing all agricultural producers today are more complex and difficult …

Land Area Available in Cuming County to Expand Livestock Operations based on Zoning Setback Requirement
A GIS was used to study the spatial impact that 1/4, 3/8, 1/2, 3/4, and 1 mile setbacks have on the area available to the livestock industry in Cuming County, Nebraska. A geographic information system was used to analyze the amount of land available under the current zoning requirements in Cuming county, Nebraska. The colored area of these maps represent the land areas that are excluded from livestock construction or expansion. These maps graphically represent the impact zoning setbacks have on the actual available land …

Phosphorous Runoff Risk During Years following Manure Application
Manure application may result in increased water infiltration and reduced runoff but it can also lead to excessive soil P levels and increased P concentration in runoff. Research was conducted to determine the residual effects of composted manure on runoff loss of water, sediment and phosphorus, and to evaluate soil P tests in prediction of P concentration in runoff. The residual effects of previously applied composted feedlot manure were studied from 2001 to the spring of 2004 at a runoff facility established in 1998 at the UNL Agricultural Research and Development Center. …

Reducing Phosphorus Concentration of Ethanol Distiller Byproducts by Using Low Grain Phosphorus Corn
Ethanol production plants are using about 800 million bu of corn each year to produce ethanol. In the ethanol production system, the starch is converted to ethanol and CO2 and the remaining grain material is called distiller byproduct (wet distiller grain plus soluble or dry distiller grain plus soluble). This byproduct is high in energy, protein, and P contents and is usually fed to feedlot cattle and other livestock. Removal of starch from grain concentrates P in the byproduct and when this high P material is added …
