 (i) that it cannot result in the release into the air of any substance prescribed by regulation 6(1) or there is no likelihood that it will result in the release into the air of any such substance except in a quantity which is so trivial that it is incapable of causing harm or its capacity to cause harm is insignificant; and
 (ii) that it cannot result in the release into water of any substance prescribed by regulation 6(2) except in a concentration which is no greater than the background concentration; and
 (iii) that it cannot result in the release into land of any substance prescribed by regulation 6(3) or there is no likelihood that it will result in the release into land of any such substance except in a quantity which is so trivial that it is incapable of causing harm or its capacity to cause harm is insignificant.
