The Mackenzie Valley Land and Water Board (the Board) is satisfied that the preliminary screening of Application MV201OX0003/MV201OL8-0002 — GNWT-Department of Transportation — Miscellaneous, Bridge Construction has been completed in accordance with section 125 of the Mackenzie Valley Resource Management Act (MVRMA).
The Board is satisfied that a reasonable period of notice was given to communities and First Nations affected by the application as required by subsection 63(2) of the MVRMA so that they could provide comments to the Board.
Having reviewed all relevant evidence on the Public Registry, including the submissions of the Applicant, the written comments received by the Board and any Staff Reports prepared for the Board, the Board has decided that:
• There is no likelihood that the proposed development might have a significant adverse impact on the environment; and • There is no likelihood that the proposed development might be a cause of public concern.
The Board is also of the opinion that the Application can proceed through the regulatory process and that any impacts of the development on the environment can be mitigated through the imposition of the terms and conditions in the attached Land Use Permit.
As a result, the Board, having due regard to the facts and circumstances, the merits of the submissions made to it, and to the purpose, scope, and intent of the Mackenzie Valley Resource Management Act and the Mackenzie Valley Land Use Regulations, has decided that this Land Use Permit be issued subject to the terms and conditions contained therein.
