1. A material transfer system for controlling dust emissions generated during a transfer operation for bulk material when material is being moved from a first location to a second location and wherein the first and second locations are spaced from each other, the system comprising,a conveyor system having at least one end portion associated with the first location for moving bulk material which generates fugitive dust emissions to the second location;

  • a chute member having opposed end portions and being positioned between the first and second locations for receiving the material from the one end portion of the said conveyor system and delivering the material to the second location, one end portion of said chute member being positioned adjacent the first location and the opposed end portion of said chute member being positioned adjacent the second location, said chute member being configured to eliminate direct impact of the material at the second location;

    a deflector member spaced from said chute member and positioned in the area adjacent the one end portion of said conveyor system, said deflector member being shaped and dimensioned so as to direct the material from the one end portion of said conveyor system onto to said chute member; and

    an enclosure member enclosing at least the one end portion of said conveyor system, said chute member, and said deflector member, said enclosure member being further positioned at least adjacent to the second location and having sufficient volume to allow for recirculation of the induced air flow associated with the moving material as such material is moved from said conveyor system to the second location, said enclosure member including increased volume in the area adjacent to said chute member, said deflector member, and in the vicinity where the material is delivered to the second location wherein fugitive dust emissions generated during the transfer of bulk material between first and second locations are substantially contained within the enclosure member.
