zone or scenic protection zone, as definedon a council zoning map (Local EnvironmentalPlan (LEP) or other planninginstrument).Suburban—an area that has local traffic withcharacteristically intermittent traffic flows orwith some limited commerce or industry. Thisarea often has the following characteristics:—decreasing noise levels in the eveningperiod (1800–2200); and/or—evening ambient noise levels defined by thenatural environment and infrequenthuman activity.This area may be located in either a rural,rural-residential or residential zone, asdefined on an LEP or other planninginstrument.Urban—an area with an acoustical environmentthat:—is dominated by ‘urban hum’ or industrialsource noise—has through traffic with characteristicallyheavy and continuous traffic flowsduring peak periods—is near commercial districts or industrialdistricts—has any combination of the above,where ‘urban hum’ means the aggregatesound of many unidentifiable, mostlytraffic-related sound sources.This area may be located in either a rural,rural-residential or residential zone asdefined on an LEP or other planninginstrument, and also includes mixed landusezones such as mixed commercial andresidential uses.Urban/industrial interface—an area definedas for ‘urban’ above that is in close proximityto industrial premises and that extends out toa point where the existing industrial noisefrom the source has fallen by 5 dB. Beyondthis region the amenity criteria for the ‘urban’category applies. This category may be usedonly for existing situations. (See example ofhow this category is used in Appendix A,Section A5).Commercial—an area defined as a businesszone, except neighbourhood business zone,on an LEP.Industrial—an area defined as an industrialzone on an LEP. For isolated residenceswithin an industrial zone the industrialamenity criteria would usually apply.7. Time of day:—day: the period from 7:00 am to 6:00 pmMonday to Saturday; or 8:00 am to 6:00 pmon Sundays and public holidays—evening: the period from 6:00 pm to 10:00pm—night: the remaining periods.(These periods may be varied whereappropriate, for example, see Section 3.3.)8. The L Aeqnoise level for a specific periodrepresents the L Aeqlevel calculated or measuredover the applicable day, evening ornight period (i.e. L Aeq, period) except whereotherwise stated (for example, school classroom,hospital).9. If existing noise levels from industrial noisesources already approach or exceed therecommended acceptable noise levels in Table2.1, any increase in these levels should bestrictly limited, as described in Table 2.2.10. In the case where existing schools are affectedby noise from existing industrial noisesources, the acceptable L Aeqnoise level maybe increased to 40 dB L Aeq(1hr).11. The acceptable and recommended maximumL Aeqnoise levels can provide a guide toapplying the negotiation process set out inSection 8. While negotiation between theproponent and the community for an agreednoise level can occur at any time, typicallythe proponent would negotiate with the EPAwhere noise-level emissions fall between theacceptable and recommended maximum. Forsite levels beyond the recommended maximumlevels, the proponent would need tonegotiate directly with the community.2.2.2 Determining the receiver typeThe selection of the type of receiver is important indetermining which noise amenity criteria levelshould apply. In most instances the receiver cat-NSW industrial noise policy18
