Maps and Resources for SEPP N-1 and NIRV
Melbourne metropolitan area
In the Melbourne metropolitan area, the State Environment Protection Policy (Control of Noise from Commerce, Industry and Trade) No N-1 sets limits for noise from industry.

In current versions of Acrobat reader, the SEPP N-1 boundary and the urban growth boundary can be displayed or switched off using the layers tool to the left side of the map.
Calculating zoning levels
The SEPP N-1 method for setting noise limits is based on:
- the land use planning zones, referred to as a "zoning level" and
- the existing background sond level measured in the absence of industry noise.
Contact EPA if you need help calculating the zoning levels when using SEPP N-1 or NIRV for major urban areas.
Regional Victoria (NIRV)
Noise from Industry in Regional Victoria (NIRV) (PDF 910KB) has two approaches for setting levels for industry noise emissions. The method to use depends on whether you are located in:
- Major urban areas (large regional towns and cities and the outskirts of Melbourne), or
- Rural areas
In major urban areas, NIRV adopts the method of SEPP N-1 for setting recommended noise levels from industry. In rural areas the NIRV method applies.
Areas of Melbourne between the SEPP N-1 boundary and the Urban Growth Boundary are major urban areas. See the maps of SEPP N-1 area above.
