From Air Quality Services
Accurate knowledge of a facility's air emissions is important for regulatory purposes, for determining available emission offsets and for developing permitting strategies. During the past five years, Source has prepared nearly 200 air emission inventories (including the air emission sections of air permit applications and SARA Toxic Release Inventories). These inventories were for facilities ranging from very large chemical complexes to small manufacturing plants.
Included in the inventories prepared by Source is a determination of fugitive emissions from valves and flanges, speciation of chemical compounds, size distribution of particulates, and calculation of emissions from storage ponds and related wastewater facilities. In-house developed computer software with comprehensive spreadsheets is used to calculate and to display facility air emissions. Preparation of process flow diagrams, material balance tables and detailed reports describing all calculations is included in Source's inventory services.
