The 8-Hour Laso of 33.5 dB(A) indicates that a noise level criteria of 57 dB(A) Lato.1e-nou (free field) is
applicable to the development (refer to Section 2) for assessment of road traffic noise impacts. For
private open space, the 60 dB(A) Lato,1enow (free field) criterion is applicable.

Based on the average background Laso noise level of 35 dB(A) (between 10 pm and 7 am) and
43 dB(A) (between 7 am and 10 pm), fixed plant noise criteria of 38 dB(A) and 48 dB(A) applies for
the nighttime and daytime respectively.
