The department has received intermittent complaints relating to odours in the vicinity of the GD Pork piggery in West Pinjarra since 2014, peaking in early 2015.
Odour field surveys were performed by odour panellists at various locations and times in the vicinity of the identified potential odour sources. The purpose of the survey was to establish the presence of odour, if any, but not the offensiveness or the unreasonableness of the possible odour impacts.
