Step 1- Do I Need to Report?

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: Metal cutting, grinding, blasting Machining, stamping, forging, drilling on metal to produce metallic products Welding Painting, using cleaning or degreasing chemicals Using any chemicals that contain VOCs Using heat for your processes Using dust collector (—– Do the Calculations —–)	If your facility is NOT located in Toronto or You only do one or more of the following activities: Operating a store Distributing alloys or metallic goods Operating a warehouse Assembling components

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:

Metal cutting, grinding, blasting
Machining, stamping, forging, drilling on metal to produce metallic products
Welding
Painting, using cleaning or degreasing chemicals
Using any chemicals that contain VOCs
Using heat for your processes
Using dust collector

(—– Do the Calculations —–)

If your facility is NOT located in Toronto

You only do one or more of the following activities:

Operating a store
Distributing alloys or metallic goods
Operating a warehouse
Assembling components

Step 2: Do the Calculation

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.

Process	Calculators	Guide
Metal Processing: – Metal cutting – Machining, drilling and other processes on metal alloys to produce or manufacture metallic products	Metal Processing (Excel) (Processes such as cutting, drilling, bending, etc on metals)
Welding	Electric Arc Welding (Excel) Resistance Spot Welding (Excel)
Dust Collection (if you have one or more dust collector)	Dust Collectors (Excel)
Painting or use of chemicals that contain VOCs	Volatile organic compounds (VOCs) (Excel)	Guide (PDF) for volatile organic compounds (VOCs) calculator
Process heating	Natural gas boilers (0-99 MMBTUs) (Excel) if you use natural gas to provide heat for your processes Click to find more calculators for process heating
If you use 2 or more calculators	Calculation of totals (Excel) (Add the results from output summary of two or more calculators into this calculator to find the total amounts and identify if any chemical meets the reporting threshold)

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)

Step 3: Compare the results

Compare the results (from the categories in the Output Summary table of the calculators) with the thresholds

Chemical Name	Sources	Threshold (kg/yr)	Category
Cadmium and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	1.0	Processed
Chromium, non-hexavalent, and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	100	Processed
Chromium VI (hexavalent) and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	10	Processed
Lead and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	10	Processed
Manganese and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	10	Processed
Nickel and its compounds	Metal cutting, processing, machining, welding; natural gas combustion	10	Processed
Volatile organic compounds total (VOCs)	Paint products, cleaning solvents, other chemicals that contain VOCs; natural gas combustion	100	Released to Air
Particulate matter (PM2.5)	grinding, cutting, blasting, sanding, welding; natural gas combustion	30	Released to Air
Nitrogen oxides (NOx)	Metal cutting, natural gas fired boilers you have used to provide heat for your processes	200	Released to Air

Step 4: Submit your report

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
