Regional Nutrient Management Ru-les 1 1 August 2011 watershed must be developed by September 2014 and implemen#ed by Au-gust 20-15. If the-March 201-8 report for the Haw River arm indicates continued impairment in t-his arm of the reserv~'rr, then. Orange ~ountymust develop a Stage If Existing Development Stormwater Prograan for this sub-watershed_ This Program- would need to be developed by September 2018 a-nd implemented by August 2019. The most recent data-collected-from within Jordan Lake is available in the 2010-DWQ water quality monitoring report-for Jordan Lake. This data documents significant water quality violations at aN three of the lake sampling locations in the Upper New Hope- arm of the lake, and lesser violations atone- of the three sampling locations in the Haw River arm of Jordan Lake. The ultimate goal of any required ~5tage II Existing Development Program for Jordan Lake wilfbe to achieve N reductions of 8 percent and P reductions of 5 percent fr-om existing-developed lands relative to the baseline values determined from existing development in 1997-2001. More-significantly, if the March-2023- DWQ monitoring report indicates that the Upper New Hope Ar-m continues to violate water quality standards, then Stage II Programs in this sub-watershed must be modified to achieve N reductions of 35 percent. F. Falls Lake Stage II Requirements Each local government located in the Upper Falls Lake watershed must develop a Stage II Existing Development Load-Reduction Program to be submitted in-2021 and then be updated every 5 years until the required-reductions in loading of 40% for N and 77% for P axe reached. If the Stage I nutrient reduction goal is met by a local government, then further nutrient reductions in Stage II must be achieved annually from existing development which are greater than or equal to the average annual reductions achieved in the last seven years of Stage I, or "provide for an annual expenditure that equals or exceeds the average annual amount the local government has spent to achieve nutrient reductions from existing development during the last seven years of Stage I." If the Stage. I goal were not met, then the local government's initial Stage II program must either achieve annual nutrient reductions from existing development greater than or equal to average annual additional reductions achieved in the highest three years of Stage I implementation, or provide for an annual expenditure that equals or exceeds the average annual amount the local government has spent to achieve nutrient reductions from existing development during the highest three years of implementation of Stage I.
