Directs the Environmental Management Commission (Commission) and the Department of Environmental Quality (DEQ) to implement the "Protection of Existing Buffers Rules" (defined by various rules as identified in the NCAC; Rules) whereby the Commission provides a minimum riparian buffer of 100 feet unless the Commission specifically finds, based on findings of fact specific to the river basin or stream segment, that such a riparian buffer would provide no additional water quality, flood prevention, or flood mitigation benefits over the buffers currently in the Rules. Directs the Commission to adopt rules consistent with the described directive. 

Repeals GS 143-214.23A, Limitations on local government riparian buffer requirements, and GS 143-214.7C(a)(1), which prohibits DEQ from requiring mitigation of impacts to an intermittent stream.
