House committee substitute to the 1st edition makes the following changes.

Amends GS 47-30(l), which provides exemptions from the statute's mapping requirements for the registration of certain plats and subdivisions, to provide that the statute does not apply to the registration of highway right-of-way plans of plats acquired by the North Carolina Turnpike Authority as provided for in GS 136-89.184 (this provision was deleted in the 1st edition). 

Amends the act's effective date provision to make the act effective when it becomes law, removing the provision specifying that the act is applicable to maps filed on or after the date the act becomes law.
