3.2. Direction-dependent separation distances
3.2.1. Introductory remarks
Direction-dependent separation distances are calculated for twoodour impact criteria used in Austria: 1 OUE/m3 and 3% exceedenceprobability, representative for recreation areas (high odour protection),1 OUE/m3 and 8% exceedence probability, representativefor residential areas mixed with commercial activity (lower odourprotection). According to the methodology outlined in Section 2,three comparisons of separation distances between AODM andLASAT are possible. For both models, separation distances can be
