Tar-Pamlico Nutrient Strategy Overview
Agricultural operations in the basin are collectively subject to two nutrient goals: a 30% reduction for nitrogen loading and no increase in phosphorus loading.
Riparian buffers are subject to protection under the Tar-Pamlico strategy, with exceptions for uses that existed before the strategy was developed. Some new uses are allowable as long as impacts are appropriately mitigated elsewhere.
Relatively populous areas in the basin are subject to rules that limit nutrient runoff from new development projects. If necessary, some nutrient loads can be offset by restoration projects in other areas after meeting onsite requirements. The following jurisdictions are subject to the Tar-Pamlico new development stormwater rules:
City of Greenville | City of Henderson | City of Oxford | City of Rocky Mount |
Town of Tarboro | City of Washington | Beaufort County | Edgecombe County |
Franklin County | Nash County | Pitt County
Resources to assist in compliance with the Tar-Pamlico strategy include:
- Tar-Pamlico 2003 Model Stormwater Program
- Coastal Plain Export Calculation Worksheets
- Piedmont Export Calculation Worksheets
- DWR Nutrient Offset Program
- DEMLR Stormwater Permitting Program
- Rules: 15A NCAC 02B .0731, .0703
- 2021 Local Program Guide
- 2021 Model Ordinance
- 2021 Model Stormwater Management Plan
Members of the Tar-Pamlico Basin Association, a consortium of wastewater dischargers, limit their nutrient loading pursuant to an agreement with the Environmental Management Commission, DWR, and the N.C. Department of Agriculture and Consumer Services. Other wastewater dischargers are also subject to nutrient limits as described in rule.
DWR and its partners actively monitor water quality in the Tar-Pamlico basin and routinely assess its performance against existing water quality standards.
