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

Revises the provisions of proposed GS 113A-52.01(b), now more specifically requiring waters that have been classified as trout waters by the Environmental Management Commission to have an undisturbed, vegetated buffer zone 25-feet wide where agricultural related land-disturbing activities defined under GS 113A-52.01(a)(1) are prohibited (previously required such activities that are located adjacent to classified trout waters to have an undisturbed, vegetated buffer zone 25 feet wide; did not explicitly prohibit the activities described in subdivision (a)(1) in the buffer zone).
