Emissions of ammonia from Danish livestock farms are strongly regulated. Manure applications to the fields are restricted to take place during the growth season and within certain limits for the total load per hectare on annual basis. Farmers need to document access to fields for application of the manure. Farmers also need to apply to the local authorities to optain permits for increasing animal productions at their farm. These applications for increasing animal production are treated using an official Guideline for Environmental Impact Assessment (EIA) of the associated ammonia loads to local nature. A structural change of local authorities in Denmark is taking place in 2007, and this change will move the obligation to carry out these assessments from the current counties to the municipalities. The current guideline for making the assessment is under review. One of the aims is to make the assessment simple to perform and updated with respect to the latest knowledge about dispersion and deposition. The present paper outlines the planned methodology behind the suggested future guideline for EIA on local nature of ammonia emissions from livestock farming in Denmark.
