CREAMFIELDS' move to Dares-bury could be scuppered by an objection from Warrington Council after residents complained the event would be too loud.
The massive weekend event, which will feature Gnarls Barkley and The Zutons, is planned to be held in Dares-bury on August 26.
But organisers are still waiting for the go-ahead from Halton Council to erect their 45,000-capacity rigs.
Neighbouring council Warrington has lodged a formal objection to the festival, saying it is concerned about the impact it would have on about 200 residents.
It says a technical assessment shows the event is unlikely to comply with the Noise Council's code of practice because people living nearby will be able to hear the music beyond 11pm.
Several residents made representations to the council to raise concerns about noise levels and the potential for congestion, litter, damage to the environment and anti-social behaviour.
But organisers of the Creamfields festival said they have 'every confidence' their licence would be granted later this month.
Chief executive James Barton said: 'Our track record shows we have the necessary expertise for staging and managing a major outdoor event, allowing thousands of people to enjoy themselves in a safe and secure environment, while effectively minimising the disruption for those living nearby.
'We have had a tremendous response from people in Halton and Warrington supporting the event.
'The business community, who will see the economic benefits, are also right behind it.'
Creamfields has been held at the former Liverpool Airport site in Speke for the past eight years.
Mr Barton said issues such as noise, traffic management, litter and anti-social behaviour had all been success-fully managed throughout that time.
The Daresbury Estate, the proposed venue, straddles the border of Halton and Warrington.
