3.10 Emissions

Emissions are the types and quantities of air contaminants released from EPNs. Emissions are
linked to FINs and EPNs, and are identified by contaminant codes. Other emissions data items
are listed below.
1. Source ID (FIN) (Mandatory).
The Source ID that generated the emissions, such as a combustion source, storage tank,
wastewater source etc.
2. Point ID (EPN) (Mandatory).
The Emissions Point associated with the Source ID, where the emissions were released
into the atmosphere.
3. Determination Method (Mandatory).
The appropriate emission determination methods.
A – AP-42
B – Material Balance (Please Specify in Comments)
D – Continuous Emissions Monitoring (CEMS)
E – Estimated (Best Guess)
M – Measured (Please Specify in Comments)
V – Vendor Data
F – Predictive Emission Monitoring (PEMS)
S – Scientific Calculations
O – Other
4. Contaminant Name (Mandatory).
The specific contaminant name from the list.
5. Contaminant Code (Mandatory).
The specific contaminant code from an agency-approved code list.
6. Annual Emissions (TONS/YEAR).
The actual (i.e., controlled) emissions for a Source ID and Point ID during the inventory
year, excluding non-routine emissions such as releases from maintenance activities and
upsets (all as defined by the regulatory agency).
7. Ozone Season Emissions (LBS/DAY) (Mandatory in certain areas).
The average daily emission rate in pounds/day from June 1 – August 31 during the
inventory year.
8. Maximum Short Term Emissions (LBS/HR).
The maximum controlled emissions for this Source ID and point during the inventory
year, expressed in pounds/hour.
