A business group lobbying for the proposed £2.8bn Manchester Transport Innovation Fund (TIF) congestion charging and transport expansion scheme has called for concessions for businesses based in Trafford and for those crossing charging boundaries more than once.
The 'United City' lobby group want business users to have their congestion charge capped for businesses crossing and re-crossing a particular boundary, for example a delivery driver making repeat journeys over the M60 - one of the congestion boundaries.
For those in Trafford, United City also want to have special business exemptions because the Metrolink line will not be ready until after the congestion charge comes into effect in 2013.
They also call for any excess income from congestion charging to be ring-fenced, and then ploughed back into public transport schemes in Greater Manchester.
United City's Chris Oglesby says: "It is conceivable that after the 30 year period for repaying the £1.2bn of government loan, it will have raised surplus income. United City is calling on the authorities to guarantee that any such surplus will be invested in Greater Manchester's public transport network.
"We have been hugely pleased at our member numbers so far, and these demands reflect their feedback to us. We understand the needs of companies which make repeat journeys across the charging rings. However, we are not calling for total exemptions, as these are precisely the companies which will benefit from reduced congestion," he said.
The group, whcih has grown to more than 50 businesses in the past 10 days, claims it is responding to the concerns of members.
United City also want an exemption for motorcycles.
Despite these reservations, the group is in favour of the scheme, which will plough £2.8bn of government funds into Greater Manchester's transportation system.
The government has provisionally approved the scheme and is now waiting for the 10 Greater Manchester authorities to vote on whether they back the scheme or not. 6 are so far in favour, while Stockport, Trafford and Bury are against, while Bolton has indicated it will run a referrendum to decide.
