Red Bull needs to clear some hurdles before the Austrian grand prix can go ahead in 2014.Wheels24 reported that Red Bull and Bernie Ecclestone announced an agreement to stage a race mid-2014 at the former A1-Ring, now called the Red Bull Ring, has been reached.APA news said the "provisional" deal is for at least seven consecutive Austrian GP.Red Bull admitted the deal is "on condition of approval by the required authorities".NOISE ISSUESOne necessary approval, it has emerged, is the extension of the circuit's allowed spectator attendance for an event from just 40 000 people on two consecutive days.Red Bull's Dietrich Mateschitz said: "The question of the limits of the spectators is to be clarified."Reports also refer to limitations of the allowed decibel noise levels at the track, and backdated permission for the formation of a spectator bank.Local ombudsman Karl Arbesser said: "The conditions (for a F1 race) will certainly not be easy to fulfil. I do not know if they (Red Bull) will have an operating license for 2014."Another local administrator, Harald Schnedl, told APA that Red Bull will have to submit a full "noise, emissions and traffic engineering concept" prior to approval.'I WILL COVER THE ORGANISATIONAL COSTS'Kleine Zeitung newspaper said the Red Bull Ring will have to improve the current media centre, which is currently "too small" for F1.Local residents could also put up obstacles.The report said: "Residents will have a say and could delay the proceedings with objections."Meanwhile, Mateschitz admitted the race will cost him money: "With the gate (ticket) receipts I will cover the organisational costs, but not the license fee."Red Bull won both of the world championships in the past three years, which was certainly an advantage to getting the race."
