Bulletin 2: Closure Report Worksheet (Appendix H) Version 2.0
Bulletin 2: Closure Report Worksheet (Appendix H) Version 2.0 [PDF 200 KB]
A company can seek a Remediation Closure Letter by submitting a Closure Report to the Canada Energy Regulator (CER). The Closure Report must demonstrate that acceptable Remediation Criteria and any site-specific conditions have been met, remedial measures or risk management controls are no longer required, and there are no potential adverse effects on people or the environment. The Closure Report should be standalone and contain sufficient supporting information and detail to demonstrate remediation has been achieved. The worksheet below replaces the Closure Report Worksheet published in Appendix H of the CER’s 2020 Remediation Process Guide. Read more about Site Closure in Section 14.
Requirement | Response | Description | Reference location in Closure Report | |
---|---|---|---|---|
Yes | No | |||

Declaration Letter |
☐ |
☐ |
The 2020 Remediation Process Guide Appendix I provides a template for the Declaration Letter to be submitted with all Closure Reports that are submitted 01 January 2021 onward. |
|
Background |
||||
Site background |
☐ |
☐ |
Summarize site history, setting, source(s) of contamination and previous site investigations. |
|
Maps, figures and supporting documentation |
☐ |
☐ |
Include site maps and figures relevant to the remedial activities, as applicable. Some examples include:
|
|
Conceptual site model |
☐ |
☐ |
Describe the conceptual site model as developed during site investigation and characterization. |
|
Commitments or conditions |
☐ |
☐ |
Reference any company commitments or CER requirements associated with the site (e.g., requirements from a Remedial Action Plan (RAP) acceptance, or conditions on an Order or Certificate). |
|
Overview of remedial activities |
☐ |
☐ |
Include the volume of all media removed from site and their disposal method(s), as applicable. If a RAP was previously accepted by the CER: Summarize the RAP. Provide a summary of the selected remedial approach(es) and the activities completed. Describe how and why the remedial activities differed from the RAP, as applicable. If a RAP was not previously accepted by the CER: Provide a summary of the selected remedial approach(es) and the activities completed. |
|
Contaminants of Concern (COCs) |
☐ |
☐ |
Present the COCs that were analyzed to determine remediation is complete. If not previously accepted in a RAP: Discuss the rationale for both the inclusion and exclusion of potential COCs to ensure that all contamination at the site has been addressed. |
|
Remediation Criteria |
||||
Soil texture/grain-size |
☐ |
☐ |
Summarize soil texture or grain-size analytical results. If not previously accepted in a RAP: Provide evidence of laboratory analytical results to support the selection of the Remediation Criteria (e.g., coarse- or fine-grained soils). |
|
Land use |
☐ |
☐ |
Provide a rationale for selected land use. See Section 11.4 of the 2020 Remediation Process Guide for further information. |
|
Remediation Criteria: Use of generic criteria |
☐ |
☐ |
If already accepted in a RAP:
If not previously accepted in a RAP:
|
|
Remediation Criteria: Use of Site-Specific Remediation Objectives (SSROs) |
☐ |
☐ |
If previously accepted in a RAP:
If not previously accepted in a RAP:
|
|
Demonstration Contamination is Remediated |
||||
Confirmatory sampling |
☐ |
☐ |
For all potentially affected media, describe the sampling protocol(s) for confirmatory sampling. Include both spatial and temporal information, as applicable (e.g., sampling frequency, seasonality for groundwater and soil vapour sampling). |
|
Analytical results |
☐ |
☐ |
Provide summary tables and attach laboratory analytical reports to demonstrate all potentially affected media are remediated. Ensure it is clear which samples represent final conditions. If generic Remediation Criteria or SSROs have been updated since remedial activities were completed, ensure analytical results are compared to the current Remediation Criteria. |
|
Groundwater consideration |
☐ |
☐ |
Compare post-remediation groundwater analytical results to current groundwater Remediation Criteria. Seasonality should be considered. If groundwater was not a component of active remediation, demonstrate groundwater was either:
|
|
Background conditions |
☐ |
☐ |
Do any parameters exceed the Remediation Criteria but are attributed to background conditions? If yes, include the rationale and supporting information to demonstrate background conditions, such as background sample analytical results. The use of statistics, publications, maps and figures may also be acceptable. |
|
Backfill quality |
☐ |
☐ |
Demonstrate backfill soil quality is appropriate for the site (e.g., pH, salinity, COCs, soil texture and any other relevant properties such as weed seed content or Clubroot testing for topsoil). |
|
Post-remediation activities |
☐ |
☐ |
Summarize the post-remediation reclamation activities and objectives for the site. Describe any reclamation related conditions and/or commitments made to potentially affected persons or communities. |
|
Engagement |
||||
Record of engagement with potentially affected persons and communities |
☐ |
☐ |
Provide an up-to-date record of engagement summarizing who was notified and/or engaged, along with any comments and/or concerns expressed by any potentially affected persons or communities. Include a summary of:
See Section 7 of the 2020 Remediation Process Guide and the 2020 Early Engagement Guide for additional guidance on engagement with potentially affected persons and communities. |
|
Record of engagement with other regulators |
☐ |
☐ |
Provide an up-to-date record of engagement with other regulators that were notified of the contamination and engaged on the plans for Remediation. Include contact information such as name(s), email address(es) and/or telephone number(s), along with a summary of the interactions. See Section 8 of the 2020 Remediation Process Guide for more information. |
