2 REGULATORY AND INFORMATION REQUIREMENTS The regulatory requirements for undertaking an HDD in Canada depend upon the jurisdiction in which a project is to be built. Each watercourse crossing may be subject to federal, provincial, territorial and local regulatory review. Many jurisdictional agencies have codes of practice, guidelines and/or policies regarding watercourse crossings, and require notifications and/or applications for permits, authorizations or licenses. The following sections describe the federal, provincial and territorial regulatory framework. Information requirements for each of these agencies are briefly discussed. This document has been written to reflect the regulatory information requirements at the time of publication. It does not address draft or proposed acts, codes of practice, guidelines or policies. Appendix B provides a brief, summary checklist of the regulatory framework and the appropriate contacts. Since the regulatory requirements are complex and continually changing across the country, the responsibility to ensure that all requirements are met falls upon the proponent. Project planners should confirm with the appropriate agencies that the applicable permit applications are made and regulatory requirements have been identified. 2.1 Federal Jurisdictions There are two federal acts which are most applicable to HDD watercourse crossings in Canada: the Fisheries Act and the Navigable Waters Protection Act (NWPA). Other acts are applicable but should only be considered in certain situations. 2.1.1 Fisheries Act The Fisheries Act was enacted to protect fish, fish habitat and water frequented by fish, and to provide for sustainable fisheries in Canada. There are several sections in the Fisheries Act (paraphrased below) which are most likely to pertain to HDD pipeline watercourse crossings: Section 20 Provides for safe passage of fish. Section 22 Provides for flow of water and passage of fish. Section 30 Provides for water diversions or intakes to have a fish guard or screen. Section 32 Prohibits the destruction of fish by any means other than fishing except as authorized by the Minister of Fisheries and Oceans (MFO) or regulation.
