The iioise generated by the proposed project would be less than the appropriate noise <br />standards at both industrial and residential properties adjacent to the project site. This would be <br />true under both normal operations conditions as well as during times when crushing wouid take <br />place ai the facility. Monitoring ofthe existing noise levels near the project site was conducted. <br />The addition of the noise generated by the proposed project to the existing noise levels would <br />result in a slight increase of noise, less than two decibels in all instances. This small increase is <br />belo�� the human threshold for perceptible detections of changes in sound levels. As a result, the <br />proposed project would not result in significant impacts to n�ise levels in the project area. <br />T M7:! �&n�rtunous Rll 1 3�C9 RoscvJle Cll�`%oiu'sumo-201 O i 0-06 do: <br />
