Attachment 5 - Environmental Noise Assessment

The results presented in Table 5.1 show that the predicted noise levels comply with the most
stringent criteria during the day and evening time periods.
Calculations have also been made to determine the noise emissions during the night period with
the site operating based on the night time period usage percentages in Table 1.1. Site operations
include one auto wash bay and super wash bay operating simultaneously, along with vehicles
travelling through the site and the continuous noise from the plant room. Table 5.2 presents the
resultant noise levels.
