18.17.3 BOWSER AIRSTRIPRegular chartered flights will transport mine personnel to and from the Project site fromthe point of origin to an aerodrome located west of Bowser Lake. Personnel will then betransported from the aerodrome to the mine camp by bus.The new airstrip will be constructed at the site of the current gravel airstrip, which will beimproved and expanded to provide a safe and maintainable facility for the chartered airtraffic. The new airstrip is shown in Figure 18.12. This site was chosen without thebenefit of meteorological information to confirm the direction of prevailing winds, orsufficient topographical or geotechnical information to confirm precise pavementstructures or earthwork quantities.The passenger aircraft used in the design of the aerodrome is the Beechcraft 1900however, the aerodrome facilities are sized sufficiently to allow DE Havilland Dash 8turboprops and C-130 Hercules aircraft upon acceptance of the sites by the aircraftoperators.The aerodrome will be designated as “Registered”, which will allows service with anapproved chartered aircraft without having to meet and comply with all of TransportCanada’s standards and operational requirements. The aerodrome will be designed toallow future “certification” for Beechcraft 1900 aircraft, should Transport Canadaregulations change regarding charter flights into registered aerodromes. Upgrading to a“Certified” status will require additional earthworks on the west approach and additionalgrading and earthworks along the edges and ends of the runway. To certify for Dash 8aircraft in the future will require even greater earth removal from the hill west of therunway. Future certification will also require significant additional administrative,reporting, safety management, wildlife management, and documentation duties on anongoing basis.The aerodrome will be supported by Instrument Approach Procedures (IAP) allowingInstrument Flight Rules (IFR) approaches and departures under suitable meteorologicalconditions.The aerodrome will have a granular surfaced runway, taxiway, and apron and will bemaintained to operate year round.Pretium Resources Inc. 18-45 1291990200-REP-R0012-02Feasibility Study and Technical Report on the BrucejackProject, Stewart, BC
