A tip will be allowed to handle waste from work on the new Bingley Relief Road.

The planning panel has approved plans to turn the disused Hallas Rough Quarry, in Cullingworth, into a dumping area for the 300,000 cubic metres of excavated waste anticipated from the construction of the new bypass.

However, conservationists have voiced their fears that the increase in lorries will lead to greater congestion, pollution and noise for local people.

The number of vehicle movements will be limited to 110 per day, with wagons making a maximum of 55 trips in and 55 out of the five hectare site on Black Moor. Lorries will take a route along the A650 to Keighley and then join the A629 Halifax Road.

Members of the Aire Valley Conservation Society claim the movement of HGVs will increase pollution, noise and congestion on the roads. They fear the development will have a devastating effect on people in Keighley, especially those living next to Halifax Road.

Secretary Penny Ward said: "Halifax Road is congested enough by slow moving vehicles. We think this is going to have a horrendous effect on residents' lives." Quarry spokesman Dennis Gillson said: "This is the nearest site to the road available. There will be less traffic than if we took it to a different site."

Planners at Bradford Council say the length of tipping will be dependent on the construction of the road, although they anticipate it will last between two and three years.

The site will operate between 7.30am and 6pm, Monday to Friday, and 7.30am to 1pm on Saturdays. No tipping will take place on Sundays or bank holidays. The site will be restored to moorland after all the waste has been deposited at the site.

Planning officers say this will have the advantage of removing an eyesore, which was not previously subject to any restoration conditions.

They also argue that it could also prevent off-road motorbike riders scrambling on the land.

Cullingworth Parish Council and Denholme Town Council both support the application, but requested that lorries were properly sheeted and that a replacement area be provided for off-road motorcyclists.
