Investigating emission limits for the Norwegian Environment Agency
The Norwegian Environment Agency has commissioned CERC to study how air concentration benchmarks for specific metals and polycyclic aromatic hydrocarbons (PAHs) correspond to annual emissions to air from a particular source.
In Norway, the major industrial sources of these emissions are non-ferrous metal industries such as aluminium and manganese production. Other contributors include graphite producers, inorganic chemical manufacturers and oil and gas refineries.
The key question in the study is how much can be emitted for a given set of emission parameters before the concentration benchmarks are reached? The answer will be determined through modelling using CERC's industrial dispersion model ADMS 5.
The Norwegian Environment Agency will use the results for screening, to decide whether detailed dispersion modelling is required for a specific facility.
