AER S-30 Sulphur Balance Reporting Project

Update September 16, 2026

Title: Sulphur Balance (S-30) Learning Module Now Available

The Sulphur Balance (S-30) learning module is now available in the external Learning Management System (LMS). We have released it ahead of schedule to give operators and reporting agents more time to learn the new process before S-30 reporting moves from DDS to Petrinex on October 8, 2026.

How to access the training

Sign in to your LMS Learning profile to find the course. No LMS profile, or trouble signing in? Contact Petrinex Administration at petrinexadmin@petrinex.ca

Before October 8, we recommend that you:

  • complete the learning module; and
  • review the TIP - AER Sulphur Balance (S-30) Reporting Moves from DDS to Petrinex; and
  • if you are using the CSV functionality rather than just online, review the CSV Spreadsheet Upload Specifications and Template
    • Interoperability (IIO) Testing of your CSV file is currently available. Review the IIO Instructions for information on how to submit your IIO test files.

Remember: September 25, 2026, is the last day to submit or amend S-30 reports in DDS. No S-30 submissions or amendments can be made in either suste, from September 26 to October 7.

Documents Available:

 The update to the CSV Upload specifications is a correction of decimals places for column P.

Update September 4, 2026: Sulphur reporting functionality will be implemented in Petrinex on October 7, 2026.  Petrinex will be unavailable from 6:30 p.m. on October 7 for code implementation, and the new functionality will be available on October 8, 2026.

AER Communication:

The Alberta Energy Regulator (AER) has published the following message on the Digital Data Submission (DDS) System regarding the upcoming changes to the AER S-30 Sulphur Balance Reporting process transition to Petrinex.

  • The Sulphur Balance Reporting System
    In fall 2026, the submission system for the S-30 Sulphur Balance Report will transition from the Digital Data Submission (DDS) system to Petrinex. Once the transition is complete, DDS will no longer be available for S-30 Sulphur Balance Report submissions, viewing historically submitted reports, or amendments to prior periods. After the transition is complete, all S-30 Sulphur Balance reporting, including amendments for prior periods, must be submitted using Petrinex and historically submitted reports can also be viewed in Petrinex. More information, including key transition dates, will be provided as it becomes available. If you have any questions about this change, contact EmissionsCompliance@aer.ca.

Frequently Asked Questions:

When will the training modules be available?

The Sulphur Balance (S-30) learning module is now available in the Petrinex external Learning Management System. If you require assistance accessing your learning profile or creating a new profile contact petrinexadmin@petrinex.ca.

When can I add the sulphur role in Petrinex and assign it to my users?

User Security Administrators (USAs) can set up their users beginning October 8, 2026, once the functionality is available.  USAs will assign either an edit role or a read-only role for sulphur reporting, depending on each user's requirements.

Will users need a separate role in addition to sulphur?

After the USA creates the two new sulphur reporting roles and assigns the required tasks, every BA user responsible for S-30 sulphur reporting must be assigned one of these roles.

  • Users with other Petrinex responsibilities will retain their existing roles and be assigned the new sulphur reporting role in addition.
  • Users whose only responsibility is sulphur reporting will only require the applicale sulphur reporting role and no other roles or tasks.
