Analysis of the inventory methods for pollutants in ambient air in the EIA reports (environmental impact assessment) for investment proposals implemented on the territory of Riew Ruse for the 2013-2016 period

Abstract

The inventory methods used for pollutants in the Republic of Bulgaria for the purposes of the EIA reports are: Updated uniform inventory methodology for emissions of harmful substances in the air (Order № 165/20.02.2013 of MEW), EMEP/EEA Air pollutant emission inventory guidebook of the EEA and AP-42, Compilation of Air Pollutant Emission Factors of EPA – U.S. Environmental Protection Agency. The choice of methods used for the assessment is made by the independent expert who works on it. As a result of using different inventory methods for pollutants in ambient air in similar installations (sites) the recorded values for the amounts of emitted pollutants are different. The purpose of the study is to make a comparison between the estimated amounts of the same pollutants in similar sites /performing one and the same activity/ by using different methods in the approved EIA reports and register the deviations; to assess the need of establishing a uniform methodology for assessing the Ambient air component in EIA reports, reflecting the essence of the planned investment - new investment or expansion of an existing site.
