Puma Energy plans to convert the old KFC building on the corner of Clontarf Road and Carrington Street into a petrol station with eight fuelling bays, a convenience store and signage. It would be next to homes on its west side and operate around the clock.
Lesley Portelli (72) has lived at the home directly next to the site since she was 16.
She said the possibility of a petrol station operating just metres from her home was stressful.
�It�s gruesome, it�s terrifying,� she said.
�We�re getting older now, my husband and I, and the stress is too much.�
A planning application went before and was knocked back by the City of Cockburn in February, pushing it in the path of the State Administrative Tribunal and a mediation period, which is currently underway.
Marisa Leccese and Carmelina Pruiti are taking up the fight on behalf of residents, who gathered at the site on Wednesday to be updated on developments so far.
Ms Pruiti said residents had concerns about traffic modelling, lighting issues, pollution and odour, and space for the trucks, among other issues.
�A lot of people nearby are elderly. They�re less likely to be out and about so problems like noise, traffic and any fumes become 24-hour issues,� she said.
�We don�t feel the data in the reports put forward adequately address these concerns.�
Fremantle MLA Simone McGurk said residents had good reason to be opposed to a 24-hour petrol station.
�Most objectionable is how close (the petrol station would be) to residents,� she said.
�The proposed area where tankers would re-fuel in the initial proposal by Puma was about two metres from a bedroom window and I just think this is unacceptable. I hope the matter gets a very thorough examination at SAT.�
Cockburn deputy Mayor Carol Reeve-Fowkes was also at the meeting but was unable to say much while the matter was before the SAT.
Cockburn planning and development director Daniel Arndt said the mediation would determine whether a compromise between the parties could be reached.
�At this stage the mediation is still ongoing and due to the planning regulations council is restricted from commenting on the mediation or any deliberations,� he said.
A spokeswoman for Puma Energy said it was working with the Cockburn council and community to reach an agreement.
�Puma Energy is confident the proposed service centre, which will operate under stringent legal and environmental codes, will have a positive impact on the Cockburn community,� she said.
