Deletes provision prohibiting local governments from regulating vegetation cutting, trimming, pruning, or removal within the limits of interstate or primary highway rights-of-way. Makes a clarifying change. Amends proposed GS 136-133.2 by removing all provisions concerning the criteria that, if found by the Department, requires the Department to deny a permit to remove vegetation. Changes the effective date of the act from October 1, 2011, to September 1, 2011 (unless otherwise specified in the act), and applies to permit applications or renewals submitted on or after that date and to offenses occurring on or after that date.
