Neuse RiverBasinwide Water Quality
Management Plans
• First in series of 5-Year plans issued March 1993 – listed 32 federal and state NPS programs
• Second – December 1998 – included the corrective actions with the NSW strategy
• Third – July 2002

Goal: 30% reduction of nitrogen within five years
Established by committee of informed scientists as the level that, if achieved,
would likely have detectable water quality improvement.
Neuse Nutrient-Sensitive Waters StrategyOrdered by House Bill 1339, ratified June 1996Administrative rules adopted December 1997
![Page 7: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/7.jpg)
Elements of the Strategy
• Point Sources
• Agriculture Sources
• Nutrient Management for Non-Ag Sources
• Urban Stormwater Management
• Riparian Buffers
![Page 8: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/8.jpg)
Strategy: Point Sources
30% nitrogen reduction within 5 years Nitrogen cap of 2.8 million pounds of
nitrogen per yearTrading program for point sources to
be implemented by a coalition of participating dischargers
An offset (in-lieu fee) fee program for new or expanding sources

Strategy: Agricultural Sources
• Goal: 30% reduction of nitrogen 1991-1995 load from agriculture within 5 year
• Activities, including livestock operations, can comply by:– participation in a collective local (county) strategy, or– installation and maintenance of specified BMPs
• Organizations:– Local (county) Advisory Committees – Basinwide Oversight Committee

Local (county) Advisory Committees (LAC) (appointed by EMC and SWCC)
Prepare county level plans for agriculture
Participants:
• NC Soil and Water Conservation Districts
• USDA – NRCS
• NC Dept. of Agriculture
• NC Cooperative Extension Service
• At least two farmers

Basin Oversight Committee (BOC)(appointed by Secretary of the Dept. of Environment and Natural Resources to oversee county level plans)
Participants:
• NC Soil and Water Conservation Districts
• USDA – NRCS
• NC Dept. of Agriculture
• NC Cooperative Extension Service
• NC Division of Water Quality
• The scientific community
• The farming community

Strategy: Urban Stormwater Management
• Required for 10 cities and 5 counties
• New development required to demonstrate loading not to exceed 3.6 lb/ac (70% of predevelopment load estimated to be 5.1 lb/ac)
• Post development peak flow not to exceed pre-development peak for 1-yr 24-hr storm.

Strategy: Riparian Buffers
• Protection of existing streamside buffers on all streams (as determined by USGS and soils maps)
• 30 feet of virtually undisturbed forest vegetation;
• 20 feet of grassed/vegetated area or harvestable trees
![Page 14: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/14.jpg)
Measurement of Progress
• Point source monitoring
• Annual reports on Neuse Agricultural Rule by the Basin Oversight Committee– Tracking installation of BMPs– Assignment of reduction credits
• Monitoring at mouth of river
![Page 15: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/15.jpg)
Reported Progress
• Point sources – monitored reductions in excess of 40 percent, achieved within three years
• Agriculture sources – BOC reported 42% reduction as of 2003
• Estimated 18% reduction in N concentration at mouth of river
![Page 16: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/16.jpg)
Limitations on Evaluation of Outcomes:Point Sources and Urban Runoff
• Point sources - No cost information reported
• Urban runoff – No instream monitoring for field measurements
of loads and reductions from baseline;– No cost information
• No systematic enforcement or verification that management plans are being followed.
![Page 17: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/17.jpg)
Limitations on Evaluation of Outcomes:Agricultural Runoff
• No cost information reported
• No instream monitoring for field measurements of loads and reductions from baseline
• No independent review of how LAC’s and BOC are assigning credits for load reductions
![Page 18: Neuse River Basin Provided by Dr. D. Monreau to Dr. G. Powell for this website](https://reader035.vdocuments.site/reader035/viewer/2022081519/56649f2b5503460f94c459c9/html5/thumbnails/18.jpg)
Limitations on Evaluation of Outcomes:General
• Monitoring only at mouth of river – cannot disentangle effects of multiple strategies, including spatial and temporal factors
• No dedicated source of revenue for monitoring, inspection, and evaluation.
• No attempt to assess risk of another round of massive algal growth-fish kill events (which, of course, is the principal objective)
