Sound Rivers’ Upper Neuse Riverkeeper and the NC Sierra Club sent a letter today to the NC Environmental Management Commission urging them to restore important language to a state report on riparian buffers. As previously reported in the News and Observer, the McCrory appointed administration at NC Department of Environmental Quality (NC DEQ) has edited reports to remove scientific based fact and in this instance downplay the importance of protecting riparian buffers.
Currently, our most polluted waterways employ buffers as a primary tool to reduce nutrient pollution. Generally, buffers of 50 feet are required on these stressed waterways. Buffers help to take up nutrient pollution, stabilize streambanks, regulate water temperature and provide habitat for aquatic species.
Requiring undisturbed vegetation close to a waterway is the best way to reduce pollution
flowing into the water and prevent erosion. Buffers that contain a mix of trees, shrubs and
grasses are more effective at capturing a wide range of pollutants than a riparian buffer that is
solely trees or grass. Trees have root systems that trap and uptake nutrients, stabilize banks, and
regulate the flow of water. Further, trees shade the river and provide an input of leaf litter and
branches that are necessary for many aquatic species.
The editing of technical staff reports by the administration of NC DEQ appears to be politically motivated in order to support the further weakening of clean water laws. The edited report mis-characterizes the true purpose of existing buffer rules and downplays the importance that buffers play in protecting clean water.
