Re: Nutrient Offset Banking Instrument Approval
Dear Sir,
On June 5, 2020, the Division of Water Resources (DWR) issued an approval letter for the
Stormwater Management Plan received for the Whirligig Station Sand Filter System (Sand Filter).
The Sand Filter was proposed as a nutrient reduction project and met the nutrient offset credit
approval standard outlined in 15A NCAC 02B .0703 (c) of the Nutrient Offset Credit Trading rule.
On July 31, 2020, the City of Wilson Stormwater Division (Bank Sponsor) submitted the Whirligig
Station Nutrient Offset Banking Instrument (NOBI) requesting DWR review and approval for the
Sand Filter to be a nutrient offset credit bank per 15A NCAC 02B .0703 (e). DWR reviewed the
NOBI document and provided comments and recommendations. DWR received a revised NOBI that
addressed all comments and recommendations. The table below summarizes the timeline of the
NOBI:
