I dunno about state law requiring them to accept oil but I can understand it on a business basis. It costs more to remove such contaminates. In fact if you are going to DIY recycle oil into diesel fuel it takes extra (somewhat expensive) effort to remove such contaminates. This means they can probably sell to recyclers for a higher price clean oil vs dirty oil.
