Frontier and Offshore Regulatory Renewal Initiative
The Frontier and Offshore Regulatory Renewal Initiative (FORRI) aims to modernize the regulatory framework governing oil and gas activities in Canada's frontier and offshore oil and gas areas. It is a partnership of federal and provincial government departments and includes participation of the Boards responsible for the regulation of frontier and offshore oil and gas activities.
The objective of FORRI is to modernize the regulatory framework by:
- Reducing redundancy amongst multiple regulations;
- Moving, where possible, to performance-based requirements instead of prescribing specific technologies/approaches;
- Bringing standards up to date where they are required; and
- Ensuring an efficient and effective regulatory regime.
Modernizing the regulations governing frontier and offshore oil and gas activities will contribute to maintaining Canada’s high standards for safety, environmental protection and resource management.
This regulatory framework applies to companies and/or individuals that propose to, or have been authorized to, carry out activities related to the exploration and drilling for, and the production, conservation, processing and transportation of oil and gas in Canada’s frontier and offshore areas. These activities include geophysical operations (such as seismic activities), exploration and development drilling, and the construction, certification, operation and decommissioning of production facilities.
The Framework Regulations
Through FORRI, government partners will work to modernize the following five regulations, and integrate these into new Framework Regulations:
- Drilling and Production Regulations (2009)
- Geophysical Regulations
- Certificate of Fitness Regulations
- Operations Regulations
- Installation Regulations
Framework Regulations Consultation Process
FORRI will consult with stakeholders, Indigenous groups (utilizing separate meetings where necessary) and the public at various stages:
- Policy intent: one-day, multi-stakeholder consultation sessions on proposed policy intention followed by a written comment period
- Anticipated March 2016 – August 2017
- Draft regulation: one-day, multi-stakeholder consultation session on draft regulatory text followed by a 30-day written comment period (materials to be shared two weeks in advance)
- Anticipated Early 2018
- Pre-publication: Canada Gazette I pre-publication on draft Framework Regulations followed by a 30-day comment period
- Anticipated Fall 2018
- Final publication: Canada Gazette II publication of final Framework Regulations at least 90 days prior to entry into force
- Anticipated 2019
Framework Regulations Consultation Process for the Policy Intent
The development of the policy intent for the proposed Framework Regulations occurred in three phases:
- Phase 1 – Board Powers, Applications, Management Systems and Operator Duties
- Stakeholder consultation commenced March 2016
- Written feedback has been received on Phase 1 from multiple stakeholders.
- Phase 2 – Reporting and Resource Management
- Stakeholder consultation commenced June 2016
- Written feedback has been received on Phase 2 from multiple stakeholders
- Phase 3 – Installations and Operations
- Stakeholder consultation commencing in June 2017 with written feedback due by September 20th 2017.
The stakeholder feedback provided to date has been posted to the FORRI web page: www.nrcan.gc.ca/energy/crude-petroleum/17729
Next Steps – Phase 3
This document outlines the proposed policy intent for Phase 3 of the Framework Regulations, specifically focusing on Installation, systems and equipment design, operation and maintenance.
Following receipt of this document, stakeholders are invited to a consultation session on July 25, 2017 in St-John’s, NL, where governments and stakeholders can discuss the various elements of the draft policy intent.
Stakeholders are invited to provide written comments on this policy intent document by September 20, 2017 to Daniel Morin (Daniel.firstname.lastname@example.org). For transparency, stakeholder comments will be posted on the FORRI web page: www.nrcan.gc.ca/energy/crude-petroleum/17729.
Following the receipt of written comments, governments will consider the feedback received, prior to submitting the policy intent for regulatory drafting. Governments will respond to stakeholders following receipt and analysis of written feedback and after a complete draft regulation has been created and shared with stakeholders.
