Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options AgEcon
Shih, Jhih-Shyang; Burtraw, Dallas; Palmer, Karen L.; Siikamaki, Juha.
The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to...

CONFINED ANIMAL PRODUCTION AND MANURE NUTRIENTS AgEcon
Gollehon, Noel R.; Caswell, Margriet; Ribaudo, Marc; Kellogg, Robert L.; Lander, Charles; Letson, David.
Census of agriculture data were used to estimate manure nutrient production and the capacity of cropland and pastureland to assimilate nutrients. Most farms (78 percent for nitrogen and 69 percent for phosphorus) have adequate land on which it is physically feasible to apply the manure produced onfarm at agronomic rates. (The costs of applying manure at these rates have not been assessed). Even so, manure that is produced on operations that cannot fully apply it to their own land at agronomic rates accounts for 60 percent of the Nation's manure nitrogen and 70 percent of the manure phosphorus. In these cases, most counties with farms that produce "excess" nutrients have adequate crop acres not associated with animal operations, but within the county, on...

Economic Impacts of EPA's Manure Application Regulations on Dairy Farms with Lagoon Liquid Systems in the Southwest Region AgEcon
Huang, Wen-Yuan; Magleby, Richard S.; Christensen, Lee A..
EPA's new restrictions on land application of manure nutrients by concentrated animal feeding operations (CAFOs) could decrease the net return of 6-17% of the medium and large dairy farms with lagoon systems in the southwestern United States. Many of the other dairy CAFOs in the region could achieve higher net income under the restrictions if they reduce feed costs by better utilizing manure and expanding homegrown feed production.

MANAGING MANURE TO IMPROVE AIR AND WATER QUALITY AgEcon
Aillery, Marcel P.; Gollehon, Noel R.; Johansson, Robert C.; Kaplan, Jonathan D.; Key, Nigel D.; Ribaudo, Marc.
Animal waste from confined animal feeding operations is a potential source of air and water quality degradation from evaporation of gases, runoff to surface water, and leaching to ground water. This report assesses the potential economic and environmental tradeoffs between water quality policies and air quality policies that require the animal agriculture sector to take potentially costly measures to abate pollution. A farm-level analysis of hog farms estimates the economic and environmental tradeoffs that occur when policies are designed to address pollutant flows to one environmental medium without considering flows to another medium. A national analysis addresses the broader impacts of coordinated (water and air) policies, including long-term structural...

MANURE MANAGEMENT FOR WATER QUALITY COSTS TO ANIMAL FEEDING OPERATIONS OF APPLYING MANURE NUTRIENTS TO LAND AgEcon
Ribaudo, Marc; Kaplan, Jonathan D.; Christensen, Lee A.; Gollehon, Noel R.; Johansson, Robert C.; Breneman, Vincent E.; Aillery, Marcel P.; Agapoff, Jean; Peters, Mark.
Nutrients from livestock and poultry manure are key sources of water pollution. Ever-growing numbers of animals per farm and per acre have increased the risk of water pollution. New Clean Water Act regulations compel the largest confined animal producers to meet nutrient application standards when applying manure to the land, and USDA encourages all animal feeding operations to do the same. The additional costs for managing manure (such as hauling manure off the farm) have implications for feedgrain producers and consumers as well. This report's farm-level analysis examines on-farm technical choice and producer costs across major U.S. production areas for hauling manure to the minimum amount of land needed to assimilate manure nutrients. A regional...
