M.G.L. c. 111, § 2B provides that any aggrieved person may appeal to the Commissioner or his designee for relief from the continuance of an Order. If the Commissioner or his designee finds that the continuance of any Order in whole or in part is unreasonable or unnecessary in light of the then prevailing conditions of air pollution, he may terminate or modify any such Order.
