Consequences of increased NOx emission to air during the treatment of gas from Kvitebjoern and the Haltenbanken Soer at Kaarstoe

This report discusses the consequences of increasing the emission to air of nitrogen oxides if landing facilities for North-Sea gas is developed at Kaarstoe, Norway. Three alternatives are considered. The pollution from such a facility comes in addition to the existing plant at Kaarstoe, the Aasgard terminal and the planned gas power station. The report considers concentrations in air, deposition to ground, impact on acidification of surface water and the impact of the natural environment. Concentrations in air have been calculated. The assessment of the deposition of nitrogen oxides to ground, the assessment of acidification of surface water and the assessment of the impact on flora and fauna are based on a consequence analysis for a gas power station at Kaarstoe. The influence of the development of the Kaarstoe plant on the local environment is largely determined by the amount of emissions and the tallness of the chimney. The regional impact is not very dependent on the emission conditions and the global impact is independent of the emission conditions and, to some extent, of the emission site.
