a5 reduced the concentration of nitrogen within New Hope Creek. This assertion is proven by the DWQ memorandum Ti•end Analysis of Nutrient and TSS Cwtcenh~ations in the CFRB (October 15, 2004). Despite increased development in the Upper New Hope Arm Subwatershed, the concentrations of total suspended solids and total phosphorus have remained constant in New Hope Creels during the 1990-2004 period, and total nitrogen has decreased steadily since 1990. Adaptive Management: L All participants of the Jordan Lake Stakeholder Project supported an adaptive management approach to the .Jordan Lalse nutrient management strategy. We recommend that the EMC include explicit provisions within the B. Evet°ett Jordmr Reservoir, North Carolina Nutrient Management Strategy and Total Maxinnan Daily Load document tlrat specifies activities and a schedule for implementation, 2. We recommend that enhanced water quality monitoring of .Jordan Lake and its tributaries begin as soon as possible. The monitoring program would last for four years, would complement the efforts of the DWQ as described iu the Nutrient Management Strategy document, and would be funded by local goverunents. The local govermnent monitoring program would consist of & in-lake locations, as well as a stream location on White Oak Creels. The monitoring program would include physical parameters, nutrients, carbon, chlorophyll a, algal species and algal density. 3. Following the four-year water quality monitoring period, local governments would fund a ane-year project that would include enhancement of the Jordan Lake Nutrient Response Model and evaluation of the TMDL and nutrient targets for Jordan Lalse. We would extend the calibration of the model to include three of the four years of water quality data collected during the enhanced monitoring program, and use the remaining year of water quality data to revalidate the model. We would use the recalibrated and revalidated Jordan Lake Nutrient Response Model to analyze the nutrient targets established by the state for the tluee arms of Jordan Lake (CJpper New Hope, Lower New Hope urd Haw River). 4. These aforementioned activities would be consistent with the DWQ schedule for the Cape Fear River Basinwide Water Quality Plan. 5. We recommend that the EMC commit to reviewing the etIlranced Jordan Lake Nutrient Response Model upon its completion, and with DWQ recommendation, approving its application for nutrient target analyses. 6. We recommend that the EMC cotmnit to re-evaluating the Jordan Lake TMDL, nutrient targets, and nutrient management strategy based on the results of the TMDL, and nutrient target analyses conducted with the approved .Jordan Lalse Nutrient Response Modeh Immediate Implementation: 1. We recommend that the EMC implement the DWQ's strategies for Agriculhu°e, Nutrient Management and Buffer Protection, and proceed to rule making as soon as possible. Local govermnents would support the state in that effort. 2. We recorrunend that the EMC implement the DWQ's strategy for New Development, and proceed to rule making as soon as possible, Furthermore, we recommend that any Storrnwater Rule for New Development apply to the entire area of the Upper New Hope Ann and Lower New Hope Arm Subwatersheds. No,jurisdiction within those areas
