Protesters have reignited their campaign to get rid of the so-called 'Penrith Pong'.
It comes after the Environment Agency investigated the factory, Omega Proteins, last month and found five issues that resulted in an increase in the smell.
Residents in and around Penrith have been fighting to bring an end to the 'vile' odour that has plagued the town for generations.
The factory responsible for the bad smell is located on the outskirts of the town.
It's an animal rendering facility which processes products from abattoirs and meat-processing plants to produce oils and meals for use in biofuels, cosmetics, oleo, pet food and power industries.
Almost 400 people have signed an online petition to block future planning applications to expand the factory.
Jeff Thomsonn started the petition:
The Environment Agency informed Penrith residents that Omega Proteins had investigated the smell and its source and found five potential issues:
- Problems with oxidisers that treat the smell.
- Refurbishment of bio-filters.
- Power outages.
- Material waiting to be processed.
- Cracks in the walls that allowed the odour to escape.
The plant's owner said they are now addressing the problem.
