Annex B: Sample report template

Part A: Emissions reporting

Facilities are asked to report their PM2.5 emissions as well as the methodology used to quantify those emissions in a table similar to the format provided below.

Annual reporting of PM 2.5 emissions
Source of PM2.5 Annual quantity of PM2.5 emitted (tonnes) Quantification methodology
Storage or handling    
Other non-point    
Road dust    
Total quantitiy emitted (t)    
Part B: Reporting on the implementation of the code of practice

The following provides a list of sample questions which may be used to demonstrate facility progress towards implementation of the code. For each recommendation in this code, facilities are asked to provide answers to the following questions:

  • Has the facility implemented the recommendation?
  • If the answer is yes, please describe how the facility has implemented the recommendation.
  • If the answer is no, please explain whether the facility plans to implement the recommendation. 
  • If the facility plans to implement the recommendation at a later date, please explain what will be done and by what date.
  • If the facility does not plan to implement the recommendation, please explain why and also describe what practices the facility has in place to ensure the optimal operation of the specified control device. 

Facilities should provide, if needed, any additional information on each recommendation.

Part C: Declaration

A declaration, as per the example below, is to be attached to each report.

I declare that this report is true, accurate and complete.
