House committee substitute to the 1st edition makes the following changes. Deletes proposed GS 106-701(a1). Instead, amends GS 106-701 to provide that no agricultural or forestry operation or any of its appurtenances is or will become a nuisance when all of the following are met: (1) there has been a changed condition in or about the locality of the operation, (2) the operation has been in operation of more than one year, (3) the operation was not a nuisance at the time the operation began, and (4) there have been no fundamental changes to the operation. Provides that this does not apply whenever a nuisance results from the negligent or improper operation of any agricultural or forestry operation or its appurtenances. Sets out five activities that are not considered exclusions from fundamental changes to the operation. Retains changes to (b1), proposed (f), and the effective date from the previous edition. Makes a conforming change to the act's title.
