This notice also sets out the deadline for filing statements of concern on these applications. For filing dates, see the section below on how to file a statement of concern.

Description of the Applications
CNRL has applied under the OSCA, EPEA, Water Act, and PLA to construct, operate, and reclaim the proposed NPE Project.

The proposed NPE Project is an extension of the existing North Mine Pit at the Horizon Oil Sands Processing Plant and Mine (Horizon) and is being developed to sustain approved production rates for Horizon.

Horizon is in the Regional Municipality of Wood Buffalo, 70 kilometres (km) north of Fort McMurray and about 20.5 km north of Fort McKay. The NPE Project will be immediately beside and east of the existing North Mine Pit and west of the Athabasca River. Development will occur in parts of Townships 96 and 97, Ranges 11 and 12, West of the 4th Meridian.

The NPE Project will be developed for about nine years. It includes the mine extension (1015 hectares) and the additional area required for overburden/interburden storage (2396 hectares), which together increase the disturbance area by about 18 per cent. The NPE Project will include the construction of works to manage surface runoff water and groundwater in the project area. As much as 4 275 000 cubic metres of surface runoff per year and as much as 1 380 000 cubic metres of groundwater per year will be collected in the project area and used as makeup water for the Horizon mine.

Pending regulatory approval, site preparation is anticipated to begin in Q4 2020.

CNRL has also submitted an EIA report, which is part of the applications to the AER.
