Environmental Monitoring System (EMS) Data Uploads

About the Environmental Monitoring System

The Environmental Monitoring System (EMS) is a database designed to capture data covering physical/chemical and biological analyses performed on water, air, solid waste discharges and ambient monitoring sites throughout the province. Most authorizations under Environmental Management Act (EMA) require monitoring data be uploaded to EMS.

This requirement is intended to consolidate our data collection and storage processes used to look for and identify trends and environmental outcomes related to your authorization.

Effluent Discharge Monitoring Data

What is it?

Data collected to show the quality of effluent (liquid) discharge that is conditionally authorized to be introduced into the environment (into water or onto land). These substances are generally, but not always, subject to monitoring requirements and discharge limits for specific parameters for the protection of the environment.

What is the information used for?

The province uses your data for a variety of reasons, including assessing compliance and conducting cumulative environmental effects assessments. Electronic data submission eases the use of data and improves our ability to communicate with you about your site.

Who is required to upload to EMS?

This requirement is for all authorizations with annual discharge fees exceeding $20,000 or securities exceeding $100,000, and for some larger municipal authorizations related to Liquid and Solid Waste Management plans. If applicable, please review the following documents for more information.

Do not add up the annual fees/security/reclamation bonds for multiple authorizations at one facility. Each of your authorizations should be assessed against the threshold (see above) independently. Please read the step-by-step guide for more information.

What are your requirements?

Generally, sections titled 'Authorized Discharges' and 'Monitoring Requirements' identify the location of effluent discharge monitoring site(s) and detail parameters to be monitored. If you are unable to determine the monitoring requirements for your current authorization, please contact your regional ministry office to confirm.

Who can upload the data to EMS?

The uploading of data to EMS, also known as electronic data transfer (EDT), is to be performed by a private laboratory that is capable of interfacing with the EMS database. This should be done after the authorization holder has taken steps to ensure the quality, accuracy and correctness of the monitoring data.

Not all laboratories are set up to upload data to EMS. It is the responsibility of the authorization holder to ensure the accuracy of the data being uploaded to EMS. Work with your laboratory to ensure your data meets professional quality standards.

For information about the database and detailed instructions on how to view data in EMS please visit the Environmental Monitoring System page.

Fees

Fees are determined by your lab. Depending on the laboratory, there may or may not be an additional cost associated with uploading this data. 

Other Authorization Reports

The upload of effluent monitoring data to the EMS database does not replace submitting routine monitoring data to the Routine Environmental Reporting Submission Mailbox (RERSM).
