Narrative:

A gulfstream III; departing teb; utilizing the 'dalton departure' procedure; ended up approximately less than 2 miles behind and approximately 300 ft below a B757; on approach to ewr. The dalton departure; a VFR departure procedure; for IFR aircraft; places (teb) departing aircraft dangerously close to ewr arriving heavy jet and other aircraft. The possibility of a departing aircraft encountering wake turbulence from an arriving aircraft is extremely great and may possibly create an extremely unsafe situation for one or both aircraft. It is impossible to achieve and or apply wake turbulence separation given the procedures as written and published today. Please review and redesign this dalton procedure prior to a catastrophic event taking place. Too many aircraft departing teb are flying into wake turbulence and therefore dangerous conditions immediately after departure.
