Appendix 9: NPRI Emission Factor Database for Alternate-Threshold Substances
A database of emission factors has been developed to assist facilities reporting to the NPRI for substances with alternate thresholds. The electronic emission factor database is included in the NPRI Reporting Software CD-ROM for 2000 or can be downloaded from the NPRI Web site at www.ec.gc.ca/pdb/npri. A full paper copy of the database can also be printed from the Reporting Software CD-ROM. The following table provides a list of the sectors included in the database. The database is not a comprehensive compilation of relevant emission factors, but instead is designed to provide reporters with a quick reference. The emission factors were compiled from a number of sources, including the US EPA's Factor Information Retrieval (FIRE) data system and its Locating and Estimating documents. Also included in the database is a table of the mercury content of various products and materials (Appendix 8) and a list of substances known to contain mercury.
Reports can be generated from the electronic database by searching the database by NAICS code, Canadian SIC code, sector description or by substance or CAS number. Details of how to use the database are included with the database on the NPRI Reporting Software CD-ROM. If you are aware of published emission factors that you feel should be added to the database, please advise your regional NPRI office, or send an e-mail to NPRI@ec.gc.ca.
