Pig Improvement Company Australia (PICA) is seeking approval to build an intensive breeding facility at the Flanagans Road property to cater for up to 15,000 pigs.

The council received 29 submissions during the public exhibition period, with seven in support of the plan and 22 objecting to the expansion of the piggery's operations.

In addition, two online petitions, totalling 9000 signatures, were lodged protesting the application, while 133 people submitted a 16-page pro-forma document expressing their objections.

The majority of objectors, drawn from right across the country, expressed their concerns over the welfare of animals at intensive farming operations.

Despite the "significant number of objections", the council's assessing officer said there were "no justifiable grounds" for councillors to refuse the application and recommended its approval.

The animal rights advocacy group Animal Liberation was behind one of the two petitions given to the council. Campaign coordinator Alex Vince challenged the report's findings because of the many problems linked to industrial and intensive farming on this scale.

"Not only does it impact the environment and local community, it poses a moral question that we have to answer for ourselves ... do we need to be doing such intensive farming of animals when there are so many other alternatives that we can easily choose?" he said.

Animal Liberation's campaign coordinator Alex Vince doubts that Wagga councillors will consider the welfare of the animals during Tuesday night's meeting that will decide if the project moves forward.

"It would be good if they considered that, but I have had experience in the past with development applications in council that go through similar stages as this one. Invariably, the welfare of the animals that will be kept in this facility is not considered," he said.

Mr Vince said the group will not stop its fight to have SunPork's development application thrown out regardless of whether it gains council's approval.

"This is something we have worked hard against in the past and we have managed to get similar development applications eventually (refused)," he said.

Robert van Barneveld, the chief executive and managing director of SunPork, which owns Pig Improvement Company Australia, was contacted for comment.

The application's environmental impact statement stated that the development would result in an extra 13 full-time jobs and "an estimated contribution to the gross regional product of $4 million". It also emphasised that the facility would be accredited by the Australian Pork Industry Quality Assurance Program.

"The proposed development presents significant economic benefits for the community, the broader pork industry as well as PICA," the report states.

"PICA is one of the largest employers in the region and the proposed development represents a capital expenditure of $9 million and a significant injection into the local economy.

"The subject site has been chosen due to its location and surrounding environment."
