(A) Projects subject to this chapter shall meet nitrogen loading targets through a combination of the following methods:
(1) Any combination of engineered stormwater controls treating runoff on the site;
(2) In an approved offsite regional engineered stormwater control; or
(3) Through the acquisition of permanent nutrient offset credits.
(B) The developer shall calculate the nitrogen reduction provided by these controls using the approved accounting tool.
(C) Proposed development projects may utilize an offsite regional engineered stormwater control, dedicated to treating an area encompassing the project, provided the engineered stormwater control is designed to meet all applicable requirements.
(D) Where a project does not meet the nitrogen target loading rate, the developer may meet nitrogen reduction needs for the project through the use of permanent nutrient offset credits. A project with less than 24% BUA may meet nutrient rate targets entirely by nutrient offset credits but must also meet low density stormwater requirements set forth in 15A NCAC 02H.1003.
(E) Proposed development undertaken by a local government solely as a public road expansion or public sidewalk project, or proposed development subject to the jurisdiction of the Surface Transportation Board, may meet nitrogen reduction needs for the project entirely through the use of permanent nutrient offset credits pursuant to the Nutrient Offset Credit Trading Rule, 15A NCAC 02B.0703.
