AN ACT to eliminate certain subbasin designations and remove the requirement for an interbasin transfer certificate for water transfers between those certain subbasins within the same major river basin and to revise 2020 farm act tmdl transport factor calculation applicability.

The General Assembly of North Carolina enacts:

ELIMINATE SUBBASIN DESIGNATIONS FOR IBT PROCESS

SECTION 1.(a)  Legislative Findings. – The General Assembly finds the following, with respect to eliminating the Haw River, Deep River, and Contentnea Creek subbasin designations:

(1)        These subbasins serve rapidly growing areas facing urgent water supply and economic development pressures.

(2)        Flexibility in intrabasin transfers within the Neuse and Cape Fear major river basins strengthens drought resilience and supports emergency water management.

(3)        Reducing unnecessary regulatory barriers allows municipalities and utilities in these subbasins to better plan and finance regional water infrastructure, improving affordability for consumers.

(4)        Existing watershed planning and management systems within the Cape Fear River and Neuse River major river basins mitigate potential environmental impacts caused by intrabasin transfers.

SECTION 1.(b)  G.S. 143‑215.22G reads as rewritten:

§ 143‑215.22G.  Definitions.

In addition to the definitions set forth in G.S. 143‑212 and G.S. 143‑213, the following definitions apply to this Part.

REVISE 2020 FARM ACT TMDL TRANSPORT FACTOR CALCULATION APPLICABILITY

SECTION 2.  Section 15 of S.L. 2020‑18, as amended by Section 14 of S.L. 2023‑137, reads as rewritten:

SECTION 15.(a)  Notwithstanding 15A NCAC 02B .0701 (Nutrient Strategies Definitions), 15A NCAC 02B .0703 (Nutrient Offset Credit Trading), and 15A NCAC 02B .0713 (Neuse Nutrient Strategy: Wastewater Discharge Requirements), nutrient offset credits shall be applied to a wastewater permit by applying the TMDL transport factor to the permitted wastewater discharge and to the nutrient offset credits as specified in the 1999 Phase I TMDL.

SECTION 15.(b)  Subsection (a) of this section applies only to wastewater discharge permit applications for a local government located in the Neuse River Basin with a customer base of fewer than 15,000 connections.Basin.

SECTION 15.(c)  The Department of Environmental Quality, in conjunction with affected parties, may begin the modeling necessary to determine new transport zones and delivery factors for the Neuse River Basin for point source discharges and nutrient offset credits. Once the Department has completed the watershed modeling, it shall provide the Environmental Management Commission a list of qualified professionals from which the Commission shall select at least two to validate the modeling. If each of the professionals selected by the Commission validate the model, the Commission may use the modeling and other information provided during the public comment period to adopt new transport zones and delivery factors, if warranted, by rule.

SECTION 15.(d)  This section is effective when it becomes law. Subsection (a) of this section shall expire when the rule required by subsection (c) of this section becomes effective.
