Public Notices Overview

A Public Notice is prepared as the primary method of advising all interested parties of a proposed activity for which a permit is sought and of soliciting comments and information necessary to evaluate the probable beneficial and detrimental impacts on the public interest.  Public notices are only prepared for projects determined to exceed minimal individual or cumulative adverse environmental effects and that may be contrary to the public interest.
