Logging operations are generally exempt from erosion control requirements. However, that only applies to logging operations and supporting activities (temp roads, etc). This does not apply to activities beyond typical logging activities, which very likely includes construction of the permanent road or grading beyond what’s necessary for logging operations. Many “logging” operations try to fly under the radar by doing grading work and permanent road building under their logging exemption; most get away with it because others don’t know the rules and unless someone complains, there really isn’t anyone out there policing it.
Forestry does require BMPs to be implemented to help control the sedimentation runoff. They are expected to do something. The NC Forest Service manages logging operation compliance but NCDEQ also manages these issues and can impose NOVs, etc.
