Última The Chesapeake Bay and the Control of NOx Emissions: A Policy Analysis AgEcon Krupnick, Alan J.; McConnell, Virginia D.; Austin, David H.; Cannon, Matthew; Stoessell, Terrell; Morton, Brian. Nitrogen oxide emissions not only affect air quality but have recently been found to be an important source of nitrate pollution in the Chesapeake Bay. This analysis examines the costs, emissions, source specific and location-specific allocations of NOx emissions reductions and the ancillary ozone related health benefits under a range of policy scenarios. The paper includes analysis of three separate policies. The first is a detailed analysis of the effect on nitrate loadings to the Bay of command and control policies specified in the Clean Air Act and as part of the OTAG process. The second is a comparison of alternative scenarios for reducing NOx emissions that meet nitrate loading goals, with or without concern for reducing ozone concentrations and the...

Ano: 1998 URL: http://purl.umn.edu/10576 Simulated Trading for Maryland's Nitrogen Loadings in the Chesapeake Bay AgEcon Hanson, James C.; McConnell, Kenneth E.. We investigate nutrient trading for point and non-point sources for the Bay Restoration Fund in Maryland. We demonstrate how to use the proceeds from the tax revenue to mimic a market by trading high-cost upgrades of sewage treatment plants for low-cost winter cover crops. Under an optimistic assumption about costs for non-point sources and naïve assumptions about the lag from planting cover crops to changes in nitrogen load, we calculate that 100 percent of abatement could be achieved at 56 percent of total costs, while in a pessimistic scenario, 100 percent of abatement could be could be achieved at 83 percent of total costs.

Ano: 2011 URL: http://purl.umn.edu/117403 A REGIONAL MODELING STRUCTURE FOR ASSESSING MANURE MANAGEMENT POLICIES: APPLICATION TO THE CHESAPEAKE BAY WATERSHED AgEcon Aillery, Marcel P.; Gollehon, Noel R.; Ribaudo, Marc; Breneman, Vincent E.. A modeling framework addresses manure management policies within the Chesapeake Bay watershed. Policy focus is on manure-land application at agronomic rates, as proposed under the EPA/USDA Unified Strategy. Manure-nutrient flows are assessed subject to assimilative capacity of farmland. National data bases and GIS coverages facilitate model transferability to other watersheds.
