Description: Lyttelton Inner Noise Control Boundary as shown in Map 5.1 of the Canterbury Regional Coastal Environment Plan 2005. This area refers to Rule 8.22 of the plan related to Discretionary Activities within the Operational Area of the Port of Lyttelton, in particular any activity related to the operation of the Port of Lyttelton that is emitting noise at any point within the Operational Area of the Port of Lyttelton, is a Discretionary Activity if the noise generated by that activity exceeds any of the following noise limits within the areas and times stated: 65 dBA Ldn average sound level calculated on an energy basis over any five consecutive days, when measured and assessed at any point on land at, or beyond, the Lyttelton Inner Noise Control Boundary. 68 dBA Ldn day-night average sound level on any day when measured and assessed, at any point on land at, or beyond, the Lyttelton Inner Noise Control Boundary. 60 dBA Leq (9 hour) time average level over any 9 hour period from 10 p.m. on any day to 7 a.m. the next day, when measured and assessed at any point on land at, or beyond, the Lyttelton Inner Noise Control Boundary. 65 dBA Leq (15 min) time average level for any 15 minute period between 10 p.m. to 7 a.m. the next day, when measured and assessed at any point on land at, or beyond, the Lyttelton Inner Noise Control Boundary. 85 dBA Lmax maximum sound level on any night from 10 p.m to 7 a.m. the next day, when measured and assessed at any point on land at, or beyond, the Lyttelton Inner Noise Control Boundary.
