Establish nutrient sensitive waters
(NSW) protection
measures (for programs with development or
redevelopment draining to NSW waters)
“Develop, adopt and implement an ordinance (or similar
regulatory mechanism) to ensure that the best management practice for
reducing nutrient loading is selected. In areas where the Environmental
Management Commission has approved a Nutrient Sensitive Waters Urban
Stormwater Management Program, the provisions of that program fulfill the
nutrient loading reduction requirement. Develop and include a nutrient
application (fertilizer and organic nutrients) management program in the
Post-construction Stormwater Management Program.”
A number of Phase II communities in North Carolina are
already meeting this requirement through one of the following programs:
- The Neuse NSW Stormwater Management Program,
- The Tar-Pamlico NSW Stormwater Management Program, or
- The Randleman Lake Water Supply Watershed Program.
Phase II communities that are NOT subject to these
programs will work with staff from DWQ to create a model Phase II NSW
Stormwater post-construction stormwater control program. The affected
Phase II local governments will have the opportunity to meet with DWQ
staff to formulate the model Phase II NSW program. You can contact
appropriate DWQ staff via the
DWQ Stormwater Unit home page.
DWQ’s vision for the Phase II NSW program is that it will require ONLY
non-structural BMPs; that is, managing the sources of nutrients through
education and pollution prevention.
DWQ staff do NOT envision that the Phase II NSW program will include
different or additional structural BMPs on new development or
redevelopment projects.
