Parts of an Emission Inventory
Emission Inventory Preparation Plan (QAPP)
Gather Data Enter Data into TEISS Submit Date to Emission Inventory System Write a Report Utilize Data for Air Quality Program
Uses of EI Data•Monitor site selection
• Land use planning
• Permitting
• Inspections
• Future needs of the program
• Yearly work schedule
• Funding
• Proximity to Sensitive Groups
