This odor impact assessment was carried out to determine the potential for odor impacts on the proposed development of an area known as the Turner Road Precinct, which is within the area of the local of Camden administration.
According to the plans for the district, it would develop into an urban community consisting of approximately 4,000 homes, business zones and facilities such as schools, shopping centers and sports fields. The current rural character of the area means that there is a potential for existing land use to conflict with the planned future use of the area, with nuisance odor impacts, as a potential odor source – a poultry farm – was identified approximately 200 meters from the southern edge. of the district. An assessment of the potential odor sources was made by visiting these sites and applying the techniques described in the NSW DEC Technical Notes "Assessment and Management of Odor from Stationary Sources in NSW" (November 2006).
It was determined that the poultry farm located near the district has the potential to encroach on some of the land earmarked for residential development within the district. It is recommended that further research be carried out to determine whether there is indeed a risk of odor impacts within the district from sources of poultry odors.

Winds from the southeast tend to be most prominent in the later hours of the day, followed by winds from the southwest, while winds from the northwest maintain an insignificant trend. Fall is the season with wind patterns closest to the annual average. Winds from the southwest are a strong feature of the season, followed by winds from the southeast.
Winds in spring are the strongest of the season, with an average wind speed of 3 m.s-1, followed closely by summer with an average of 2.9 m.s-1. The length of the triangles, or "petals", indicates the frequency at which the wind blows from the direction shown. In the assessment of wind resources in the vicinity of the site, attention has been paid to a poultry farm located approximately 200 meters from the southern boundary of the site.
The population near the farm is reduced due to the intention to establish an industrial area on the west side of the district, including the southwestern corner of the district, which is closest to the poultry farm. The terrain around the farm rises in a ridge to the northeast of the farm and dips in the south and southeast directions. The Turner Road Precinct, located north of the farm, would therefore be uphill from the farm.
Since winds must blow in the direction of a receptor (±40 degrees) more than 60% of the time to warrant the use of a wind frequency factor of 1.5, this choice is also eliminated. In addition to the aforementioned odor sources, a proposed sewage treatment plant is the only other odor source believed to have development implications for the area. The exact location of the STP and associated pumping stations was however not known and thus no comment can be made on the consequences for the area.
It should be noted that the perimeter defining the separation distance is only valid for the Turner Road area north of the poultry farm, as the separation distance will vary in other directions when considering terrain, populations, vegetation and wind frequency. Note that the contours shown in the figure are not the original contours, but a recreation of the original contours by tracing. However, the recreated contours are accurate enough to see the effects of the poultry farm on the Precinct predicted by the modelling.
Figure 4-3 shows that the predicted layer 2 OU is approximately equal to the perimeter of the calculated separation distance north of the farm. Model results again support a commercial/employment use of the southwest corner of the district.
The obvious solution to development restrictions on odor-affected land within the district is for developers and/or the council to either buy the poultry farm land and close the farm, or help relocate the farm, should the farm operator agree to the proposal. It is recommended that Council and Oran Park stakeholders consider entering into negotiations with the poultry farm operator if the south west corner of the precinct is to be developed for residential use.

Odour Sources in Commercial / Employment Areas
A Level 1 Odor Impact Assessment was carried out for the proposed development of the Turner Road area in residential areas and associated facilities. The investigations carried out as part of this study were in accordance with the requirements for a Level 1 assessment as set out in the current NSW DEC Technical Notes. It was determined in this assessment that land planned for residential development could be affected by odor impacts due to the presence of a poultry farm 200 meters south of the Ward.
Other bird farming operations further afield do not appear to pose any risk of odor impacts to the area. It is assumed that odors from grazing animals in the area will not have any effect on the development. No other significant sources of odor have been identified either within the area or near it.
This report provides recommendations for further assessment, including a Tier 3 odor impact assessment, and management strategies such as the level of development. Most of the recommendations understandably refer to the aforementioned poultry farms, as they have the greatest consequences for the Area.
