Directive 98-4: Interstate Animal Waste Distribution and Use Technology (13 KB) (Order hard-copy)

Publication date: 12/8/1998 | Type of document: Directive

The Interstate Animal Waste Distribution and Use Technology Directive supports the nutrient reductions goals of the 1987 Chesapeake Bay Agreement and the opportunity that it provides for all states within the Chesapeake Bay watershed to reduce the potential for nutrient loadings from animal wastes. In addition, technological advances are needed to develop sustainable systems to advance the re-utilization of nutrients contained in animal wastes.

The Phosphorus Detergent Ban (132 KB)

Publication date: 6/19/2000 | Type of document: Report

The phosphorus detergent ban was implemented in the Bay signatory jurisdictions in the mid to late eighties. After the ban's implementation, it became clear that the ban resulted in a significant reduction of discharge in phosphorus from wastewater treatment plants, the ban did not cost the consumer money, and the ban often resulted in O & M cost savings for the wastewater treatment plants. Phosphorus bans limit, to trace amounts, the amount of phosphorus that can be used in detergents and other cleaning products. The P ban resulted watershed wide in a reduction of influent P concentrations of 25-30% to wastewater treatment plants. Phosphorus loads to the bay declined by 6 million ...

Animal Nutrition Technology Exchange - Proceedings (524 KB) (Order hard-copy)

Publication date: 7/1/2000 | Type of document: Report

During the past several years, considerable attention has been directed at the potential environmental impacts of agriculture in the Chesapeake Bay Watershed. A primary focus has been on the potential nutrient loadings to surface and groundwater resulting from animal agricultural sources. There is an emerging body of science-based information on the formulation of animal rations that have the potential to cost-effectively achieve the objectives of producers and also result in potential reductions in the nutrient content of manures at the point of excrement. The Chesapeake Bay Program's Agricultural Nutrient Reduction Workgroup planned a technology exchange of the latest advances in animal ...

Directive 04-3: Building New Partnerships and New markets for Agricultural Animal manure and Poultry Litter in the Chesapeake Bay Watershed (192 KB)

Publication date: 1/10/2005 | Type of document: Directive

Agriculture is a significant source of nutrients entering the Chesapeake Bay, with animal manure and poultry litter contributing about half of the agricultural nutrient load. As animal operations become more concentrated and the acreage of cropland available for manure application is lost to development, the challenge of manure management will only intensify.

Estimates of County-Level Nitrogen and Phosphorus Date for Use in Modeling Pollutant Reduction (1.86 MB)

Publication date: 6/1/2009 | Type of document: Report

This report documents the calculations and procedures for the preparation of the input data to the Watershed Model - HSPF Phase 5. These calculations are used for creating the calibration data as well as scenario data. They form the basis of the Nutrient and Sediment Scenario Builder tool. The data created in this tool include: manure and chemical fertilizer applications by each nutrient type, land use in acres, plant uptake (the monthly amount of total nitrogen and total phosphorus taken into the entire plant -- roots, and all above-ground parts), nitrogen fixation (the amount of N fixed by leguminous plants each month), area of soil that is not covered by residue ...
