Federal Greenhouse Gas Reporting Program – 2018 Reporting Year

     Posted by Marnie Freer on

Federal Greenhouse Gas Reporting Program – 2018 Reporting Year

The 2018 Reporting Period was opened on Friday, March 29, 2019 for the Canadian Greenhouse Gas Reporting Program (GHGRP).  Reports are due June 1, 2019 via the Single Window system, and pertain to GHG emitted between January 1 and December 31, 2018.  For most facilities, the reporting threshold is 10 000 tonnes of CO2eq emitted during 2018.  In accordance with the 2018 Reporting Notice published on January 19, 2019, the 2018 reporting year encompasses Phases 1 and 2 of the expanded reporting requirements.  

Facilities covered under Phases 1 and Phase 2 must utilize specific quantification methodologies to estimate emissions which are detailed in Canada’s Greenhouse Gas Quantification Requirements for 2018.   Phase 1 and 2 activities include:

  • CO2 capture, transport, and storage activities
  • mining
  • electricity and heat generation
  • petroleum refineries
  • the production of:
    • cement
    • lime
    • aluminium
    • iron and steel
    • ethanol
    • ammonia
    • nitric acid
    • hydrogen
    • pulp and paper
    • base metal

Due to similarities with Provincial reporting requirements, facilities in BC, ON, PQ, NS and NL can elect to submit their provincial report to the GHGRP to satisfy 2018 reporting requirements.  Environment and Climate Change Canada has not indicated whether this coordination will be offered in subsequent years.  More details are available on the GHGRP Reporting website.  

Contact LEHDER for more information and assistance.

The following information was disseminated by the Greenhouse Gas Reporting Program of Environment and Climate Change Canada on May 4, 2018 and includes a list of resources now available for 2017RY GHG Reporting.


Environment and Climate Change Canada (ECCC)’s Greenhouse Gas Reporting Program (GHGRP) is accepting GHG reports for the 2017 calendar year:

Available Resources

Here are resources available to help you report to the GHGRP (includes newly added resources).

We conducted several Webex information sessions in April to explain the general requirements (for all facilities) and newly expanded requirements (for specific facilities). We also gave a demonstration on how to use the Single Window to submit a GHG report.

NEW! Below are links to the information provided during these sessions.

Policy Summary on Cumulative Effects Assessment in Air Approvals

     Posted by LEHDER News on

In November 2017, the MOECC proposed an air approvals policy with the intent to more effectively consider cumulative impacts from multiple air pollution sources. The final policy decision notice was published on the Environmental Registry of Ontario (formerly EBR) on April 26, 2017. The policy will take effect on October 1, 2018.

Impacted Facilities

The policy applies to ECA applications for new or expanding facilities located in Sarnia/Corunna that emit benzene, and those in Hamilton/Burlington that emit benzene or Benzo[a]pyrene (BaP). Key definitions are shown below.

New Facility: no construction of any part of the facility has occurred before the date that the ECA application was received by the Ministry, and no ECA has been issued in respect of any part of the facility before the date that the ECA application was received by the Ministry.

Expanding Facility: the application involves a modification at the facility that will result in an increase in production rate; or a net increase in the POI concentrations for benzene or benzo[a]pyrene compared to the ESDM report that was submitted in respect of the facility’s current approval; or an increase in emissions of benzene or benzo[a]pyrene.

The MOECC has conducted multi-source modelling to identify areas of elevated contaminant concentrations within these cities and has classified specific areas according to the level of cancer risk (Level 1/2/3). Sarnia/Corunna is classified as a Level 1 area, and Hamilton/Burlington has a mix of levels 1, 2 and 3.

Required Actions

Areas with higher cancer risk will be required to undertake more detailed assessments to support ECA applications, and may be required to install specific equipment in accordance with Technology Benchmarking studies. The Action Levels and required actions are detailed in the table below. 

Action Level Cumulative Concentration/ Lifetime Incremental Combined Cancer Risk Management Actions
N/A <1 in a million Does not trigger further action
1 1 to 10 in a million No further action for industry.
Triggers periodic evaluation (by ministry) to determine if the Action Level changes
2 > 10 to 100 in a million ECA Applications for new or expanding facilities may be required to:
1. include a technology benchmarking report with some exceptions
2. include best available pollution control methods
3 > 100 in a million ECA Applications for new or expanding facilities may be required to:
1. include a technology benchmarking report with some exceptions
2. include pollution control methods to achieve the lowest possible emission rates as compared to an  existing pollution source of the same kind globally

Impacted facilities located in Action Level 2 or 3 areas will be required to participate in pre-consultation with Approvals Branch at least 9 months prior to submission of the ECA application. The meeting will provide the MOECC an understanding of dominant sources and assist in determining the scope of the Technology Benchmarking Report (TBR).

Facilities located in Sarnia/Corunna will not be required to complete any additional actions for their ECA applications under this policy since the entire area is classified as a Level 1 at present. However, it should be anticipated that additional scrutiny and detailed review of calculations, modelling and documentation related to benzene is a potential.

CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines Released

     Posted by LEHDER News on

CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines On November 18, 2017, notification of the release of the CEPA Guidelines for the Reduction of NOx Emissions from Natural Gas–fuelled Stationary Combustion Turbines were posted to the Canada Gazette. This guideline was developed to support the federal, provincial and territorial air quality management system (AQMS). The AQMS includes Canadian ambient air quality standards for fine particulate matter and ground-level ozone, base level industrial emissions requirements (BLIERs) and local air zone management by the provincial/territorial jurisdictions.

This guideline introduces a NOx emission limit that is up to 50% more stringent than emission limits set out in the national emission guidelines for stationary combustion turbines published by the Canadian Council of Ministers of the Environment (CCME) in 1992 for combustion turbines commissioned after January 1, 2020. The Minister of the Environment and Climate Change recommends that the appropriate regulatory authorities adopt the guidelines as a baseline emission limit for NOx from natural gas-fuelled stationary combustion turbines.

These guidelines will provide the basis for the provinces and territories to adopt policies which incorporate these NOx emission guidelines however, the guidelines do not prevent the provinces and territories from adopting more stringent emission requirements for combustion turbines. Additionally, the Minister of the Environment and Climate Change continues to recommend those requirements of the 1992 CCME guidelines that have not been superseded by the requirements in this document.  A copy of the guideline is provided below.
