Emissions Inventory

Every three years the District performs an emissions inventory for the majority of our permitted sources. The last complete inventory was for emissions in 2007. An annual emissions inventory is conducted for major and special interest sites. The tables and charts below document the "criteria" pollutants and particulate matter observations and estimates for inventory year 2007.
