Code of practice for the management of air emissions from pulp and paper facilities: appendix 2

Appendix 2: characterization of sulphur dioxide and total particulate matter air emissions

1. General

Characterization of the emissions should include the following types of emission sources:

Characterization of the emissions should be expressed as follows:

The characterization of SO2 and TPM is based on a calendar year from January 1 to December 31.

2. Estimation methods

Emission sources subject to the code of practice can be characterized using the following measurement or estimation methods which are listed in hierarchical order:

  1. Measurements using a continuous emission monitoring system (CEMS), only if it is calibrated and maintained in accordance with approved provincial or federal methods.
  2. If no valid CEMS data is available, use measurements from a recognized sampling method listed in section 3.2.
  3. If no emission measurements are available for the reporting year, use a site-specific emission factor for the emission source, calculated from the previous year’s measurement results. The equipment must not have undergone major modifications that would affect the validity of the site-specific emission factor.
  4. If no site-specific emission factor is available, use industry-specific or generic emission factors such as AP-42Footnote 1 to estimate SO2 or TPM emissions.
  5. If no generic emission factor is available, use engineering calculations.

3. Guidance

This section provides guidance on how to calculate the annual SO2 and TPM emission sources depending on the measurement or estimation method used:
