Calculation Tool for
Dust Collectors
Version: 3.2, Last Updated: June 07, 2013 by AK & ZI
This page contains necessary instructions that will help you use this calculator to estimate the amount of priority
substances and other chemicals that are manufactured, processed, otherwise used (MPO) and released during the
operation of dust collectors.
How to use this 1. Click on the "Input-Output" Tab
calculator:
2. Fill out the appropriate amounts in the yellow boxes
3. Scroll down to view the Output Summary
Input summary: 1. Select the industry or process most closely related to your facility
2. Enter the airflow rate for each dust collector
3. Enter the operating schedule for each dust collector during the reporting year
Output summary: This table gives you the estimated quantity of ChemTRAC priority substances this process
manufactured, processed, otherwise used and/or released for the reporting year.
Other processes: If your facility has other activities or sources that MPO or release priority substances (chemicals), then you need to calculate the am
Total MPO and Once you have your estimates for activiti(es) or process(es), enter the amounts of MPO and
Releases: release of each substance from each process into the "Calculation of Totals" calculator
(available at www.toronto.ca/chemtrac) to determine if you need to report.
Before you start - the airflow rate for each dust collector
make sure you have: - the operating schedule for each dust collector during the reporting year

Definitions1
Manufacture - To produce, prepare or compound a priority substance and includes the conincidental production of a
priority.substance as a by-product.
Process - The preparation of a priority substance, after its manufacture, for commercial distribution and includes the
preparation of a substance in the same physical state or chemical form as that received by the facility, or preparation which
produces a change in physical state or chemical form.
Otherwise Use - Any use, disposal or release of a priority substance at a facility that does not fall under the definitions of
"manufacture" or "process." This includes the use of the priority substance as a chemical processing aid, manufacturing aid
or some other use.
Release - The emission or discharge of a priority substance, whether intentional, accidental or coincidental, from a facility
into the environment.
