Incinerator plans for Javelin Park, near junction 12 of the M5, could be modified to reduce the size of the burner to 36 metres in height.
David Elvin QC, barrister for Gloucestershire County Council, who are defending their decision to refuse the plans by Urbaser Balfour Beatty, made the claim at a planning inquiry on Tuesday.
Diana Shirley, from campaign group GlosAIN, said: “Mr Elvin spent time on referring to the scale and design. By using examples of other energy from waste sites in the UK, Mr Elvin demonstrated that it should be possible to reduce the size of the building to around 36 metres without the need to sink it into the ground therefore indicating that Urbaser Balfour Beatty had not attempted to mitigate the size of the building.”
The comments came as the inquiry continues to rumble on, with a report expected in March by planning inspector Brian Cook.
Mr Cook’s recommendations will then go before Eric Pickles, secretary of state for communities, who will have the final say on whether to allow the burner.
