Potash sector: code of practice overview

The code of practice for the management of PM_2.5 emissions in the potash sector in Canada has been in effect since September 9, 2017.

Objective

This code of practice aims to identify and promote best practices intended to control and minimize fine particulate matter (PM_2.5) air emissions. Adoption of best practices will facilitate continual improvement in environmental performance for PM_2.5 in this sector.

Target audience

The code of practice is intended to be used by potash mining facilities, whether they use conventional underground mining or solution mining.

Adopting the code of practice

If the code of practice applies to your facility, you are encouraged to:

• apply best practices appropriate to your facility
• monitor new or modified procedures on a regular basis and retain information to demonstrate that the objectives of the code are being met
• quantify PM_2.5  emissions from your facility on a regular basis using standard methods
• submit annual reports containing total emissions of PM_2.5 by source as well as the methodology used to quantify those emissions
• submit details on the implementation of the recommendations in the code every two years

Reporting

If your facility was in operation prior to December 31, 2017:

• annual reports are due by June 1 every year for the previous calendar year (Jan 1 to Dec 31)
• details regarding implementation of the recommendations in this code are due by June 1 of every odd year for the previous calendar year (Jan 1 to Dec 31)

If your facility started operating after December 31, 2017:

• annual reports are due by June 1 of the year immediately following the first full or partial calendar year of operation
• details regarding the implementation of the recommendations in this code are due by June 1 of the second year immediately following the first full or partial calendar year of operation, and every two years thereafter

You should send your annual reports by email to ec.cop-cdp.ec@canada.ca. 

Performance results to date

All 12 facilities subject to the code of practice submitted their annual reports in 2018 and 2019.
