Updated Draft Water Supply Watershed (WSW) Model Ordinance
The Updated Draft Water Supply Watershed Model Ordinance was considered by the EMC's Environmental Management Commission (EMC) at their September 9, 2021 meeting. The EMC recommended that the UNC School of Government review the ordinance. After appropriate UNC-SOG comments are incorporated, NCDEQ will seek approval of revised ordinance in 2022.
