    From Table 2, the following average ambient noise levels should be noted:

    o      LAeq,T:
                o     daytime:    49.4, 48.9, 49.8, 49.2, 48.5, 48.1, 52.3     Average = 49.6 dB(A);
                o     evening:    44.8, 46.5, 44.3, 53.1, 44.4, 52.7, 45.9     Average = 47.4 dB(A);
                o     night-time: 42.0, 43.7, 41.4, 43.1, 43.2, 42.2, 43.6     Average = 42.7 dB(A);

    o      LA1,T:
                o     daytime:    58.4, 57.2, 58.6, 59.0, 57.7, 57.2, 63.1     Average = 58.7 dB(A);
                o     evening:    53.4, 55.9, 52.8, 57.7, 53.1, 57.7, 53.5     Average = 54.9 dB(A);
                o     night-time: 50.9, 51.4, 49.8, 52.4, 52.6, 52.5, 52.7     Average = 51.8 dB(A);

    o      LA10,T:
                o     daytime:    51.3, 51.1, 51.5, 51.9, 51.1, 50.7, 56.1     Average = 52.0 dB(A);
                o     evening:    47.4, 48.5, 46.9, 55.7, 46.8, 55.1, 48.3     Average = 49.8 dB(A);
                o     night-time: 44.3, 45.5, 44.1, 45.3, 45.4, 44.3, 45.8     Average = 45.0 dB(A);

    o      LA90,T:
                o     daytime:    42.1, 43.6, 43.9, 41.0, 41.8, 41.3, 43.2     Average = 42.4 dB(A);
                o     evening:    37.7, 40.6, 38.4, 47.5, 37.9, 46.9, 41.2     Average = 41.6 dB(A);
                o     night-time: 36.8, 38.3, 35.2, 37.0, 36.7, 35.6, 37.5     Average = 36.7 dB(A).

    Based on the above 2018 background noise levels the appropriate noise limits are:

    Closest Residences to North-east

    •      steady state noise: background + 0 dB(A): daytime = 42 dB(A) LA90,T;
                                                     evening = 42 dB(A) LA90,T;
                                                     night-time = 37 dB(A) LA90,T;

    •      time varying noise: background + 5 dB(A): daytime = 47 dB(A) LAeq,adj,T;
                                                     evening = 47 dB(A) LAeq,adj,T;
                                                     night-time = 42 dB(A) LAeq,adj,T.

    As the 2018 ambient noise assessment has resulted in lower noise limit criteria than the 2009
    assessment the above 2018 noise limits are the noise limits that have been adopted in this report for
    noise from the subject site.
