The adminsitrative rules on this page are provided for the convenience of interested parties. While DES has taken care with the accuracy of the files accessible here, they are not necessarily the "official" administrative rules of the N.H. Department of Environmental Services. Administrative rules are periodically revised and readopted. Although every effort is made to see that the rules on this page are the most current versions available, some lapse in time may occur between adoption and the electronic posting of new rules or other files which may alter the meaning or context of those files. An "official" hard copy of all DES-related rules may be obtained from the DES Public Information and Permitting office, (603) 271-2975.
