Re: NPDES Permit No. NCC000001
Annual Report for 2020
Dear Danny:
The Neuse River Compliance Association is pleased to submit its 2020 annual report as required in
the above referenced permit. As included in the attached report, the co-permittee members
delivered a total of 516,645 pounds of total nitrogen to the Neuse Estuary during calendar year
2020, approximately 43% of the permit limit of 1,187,213 pounds for 2020.
We are very proud of the continued accomplishments of the Association and the efforts made by
our members to control nitrogen loading to the Neuse River Estuary.
We hope that the enclosed report provides the detailed information that the Division has requested.
If you have any questions, or if you need any further information, please contact our Executive
Director, Haywood M. Phthisic, III, at 919.796.8049.
