Oil & Gas



In the Know about NOx?

March 10, 2017

In 2016, the Canadian government released new federal regulations under the Canadian Environmental Protection Act regarding NOx emissions limits and the impact that they will have on the oil and gas industry. The following blog provides an overview of the regulations and how WSP can help oil and gas producers and facility owners to move forward.


What does NOx mean for you?

Do you ever walk around your facility and wonder: how does NOx and the new government regulations impact my business? WSP has regulatory and engineering professionals within the Oil and Gas Sector as well as Environmental and Air Quality specialists that can assist impacted companies with strategies for achieving compliance.

At times like this, our clients are asking us - how does this impact the Oil & Gas industry and what do we need to know going forward? Now is the time to start evaluating existing facilities and meeting with regulatory experts to plan for these changes.

We can support your company with the following actions:

  • Determine the NOx emissions of pre-existing and modern engines. This would be completed using manufacturer data, emission testing, company records, etc.
  • Identify which sources of NOx emissions are not compliant.
  • Plan how to group emission sources into subgroups for classification at flat rate emission sources or yearly average emission sources.
  • Identify which engines will need to be replaced or retrofitted to meet new performance standards.
  • Initiate the design work required for retrofitting and replacing engines in the field.
  • Confirm and maintain compliance through reporting, record keeping and emission testing programs.


You might be wondering how we would work with you to complete the actions outlined above. Here is a step-by-step summary of how this relationship works:

1. Initial Meeting

This kick-off meeting would include our regulatory team, project manager, client and the client’s regulatory team (if applicable). The purpose of the meeting would be to gain an understanding of objectives and scope out deliverables. For example, do you just want an understanding of the impacts to your business, do you want a detailed plan with timelines, budgets, etc?

2. Record Review

We will require access to your facility records to gather and evaluate existing data. We would use this to create a clear picture of current status with regards to these new regulations.

3. Detailed Plan

We will put together a detailed plan for you based on your objectives. This would include a detailed scope, budget and schedule for regulatory and engineering support (if requested or required).

4. Approvals

Next we would review the budget and obtain the required client approvals to move forward with executing the detailed plan.

5. Execution

Then we will execute the detailed plan. Most plans will take on the form of a series of smaller project, prioritized by risk, to be completed over the next few years.


Where to go from here

If you have any questions about these new legislative requirements, we can work with you to help identify areas of non-compliance and draft a plan for a smooth, timely, transition to meet the new NOx emissions compliance standards.
