The process of air blowing of asphalt could not only be conducted at oil refineries but also at asphalt processing and asphalt roofing plants. The emissions of air pollutants in that plants depend on various parameters like process conduct and measures to control and abate emissions. All that information is not available to determine the activity rates and emission factors. The Tier 2 emission factors for asphalt blowing in the EMEP/EEA air pollutant emission inventory guidebook 2019 only are uncontrolled emission factors based on US plants before 1980 seeming unsuitable to represent national conditions. Therefore it is planed to gather information to report emissions on a Tier 2 level. That reporting could not start before submission 2022. | The process of air blowing of asphalt could not only be conducted at oil refineries but also at asphalt processing and asphalt roofing plants.
