Generator: any person, by site, whose act or process produces hazardous waste identified or listed, or whose act first causes a hazardous waste to become subject to regulation. ( Please note this is a tricky question; if an owner hires a contractor to remove waste and stores it in the contractors site to be taken at a later time for disposal, the owner is still the generator as long as the contractor does not process or change the waste. )
