All 3 Nutrient StrategiesAddress: chlorophyll-a impairments point & nonpoint sourcesGoal: decrease nutrient loading, achieve chl-a standard Effective dates: Neuse (1998) Tar-Pamlico (2001) Jordan (2009) 3
Agriculture Nutrient Strategies Goals4 (baseline)Nitrogen reductionPhosphorous reductionNeuse (1991-1995) 30%- Tar-Pamlico (1991) 30% no increase Jordan (1997-2001) Haw 8% 5% Upper New Hope 35% 5% Lower New Hope no increase no increase

Looking ForwardNeuse and Tar-Pamlico - current rules - submit ag reports to EMC annually - rules readoption proposals submit ag reports to DEQ annuallysubmit entire nutrient strategy reports for to EMC bienniallyJordan - NC Policy Collaboratory report and models by Dec 31, 2020 - rule readoption begins by Dec 31, 2020 Statewide - loss of funding for staff and data collection 18
