But applicant Olsons Eggs said City of Launceston council officers were satisfied that odour, noise and stormwater runoff would not impact the environment or neighbouring properties.

Aldermen will vote on Monday whether to approve the discretionary planning permit for Olsons to run 7200 free-range chickens on its Quills Road property, which neighbours a bed and breakfast business run by Rhonwen Pannenter.

The council had previously approved a 950-square metre shed to be built on the Olsons property, but construction was halted after it was discovered the chickens would be housed within the recommended 500-metre attenuation distance from neighbouring homes.

Poultry farmer Chris Olson said qualified testing of soil, water, runoff, odour and noise had proved the project worthy of discretionary approval, but Mrs Pannenter said the shed threatened her business.

‘‘It has caused a lot of anxiety in this community, not just for me but for a lot of people who live nearby and who have properties that back onto the waterway,’’ Mrs Pannenter said.

‘‘The smell, the noise ... We may even have to consider shutting our business down.’’

There were 15 representations made against the chicken shed, with complaints ranging from potential impact on the Pipers River to the effect on downstream properties.

Council officers recommended that aldermen approve the shed, subject to a number of conditions, including compliance with a nutrient management plan, a limit on the maximum number of birds to be kept on the premises and regular monitoring of stormwater runoff, surface water and soil.

Olsons Eggs is a family-run business that also houses about 30,000 birds at its Brown Mountain Road farm, which is just north of the proposed expansion.
