Metal Processing – ChemTRAC Reporting
Use the following assessment process for ChemTRAC reporting on business activities in this sector.
You May Be Required to Report | You Are Not Required to Report |
If your facility is located in Toronto
and You do one or more of the following activities:
(—– Do the Calculations —–) |
If your facility is NOT located in Toronto
or You only do one or more of the following activities:
|
The documents below are available by contacting: chemtrac@toronto.ca or 416-338-7600.
Review the processes below and click on the related calculators. If you use more than one calculator, use the “Calculation of Totals” to add up the use and release amounts.

Keep the following records and supporting document for 5 years, including:
– Calculation files
– Summary of the alloy types and the total weight of each alloy you used for the reporting year
– Summary of the amount of paint products, cleaning or degreasing materials or other chemicals that contain VOCs along with their MSDS for the reporting year
– Summary of type of electrodes and the weight of each electrode you used for the reporting year
– The monthly summary of natural gas used for the reporting year, if you used natural gas for any process heat
– Confirmation page that you printed after submitting your report (see step 4)
Compare the results (from the categories in the Output Summary table of the calculators) with the thresholds
Chemical Name | Sources | Threshold (kg/yr) |

Submit your Report if any of your amounts are equal to or exceed the reporting thresholds
Or
if all of your amounts are below the reporting threshold, you may Submit a Report as a below threshold facility
