I <br />Consensus Principles <br />Consensus Principle #9 includes the following with regard to the development of the Falls Lake <br />Rules: <br />"...relied on a limited database which will be substantially enhanced by a more rigorous <br />program of sampling, monitoring and analysis." Furthermore: "The EMC [Environmental <br />Management Commission] should therefore begin a re- examination of its nutrient <br />management strategy for Falls Lake by January 1, 2018. The re- examination should <br />consider, among other things, (i) the physical, chemical, and biological conditions of the <br />Lake with a focus on nutrient loading impacts and the potential for achieving the Stage 1 <br />goal by 2021 as well as the feasibility of both achieving the Stage 2 reduction goals and <br />meeting the water quality standard for chlorophyll -a in the Upper Lake, (ii) the cost of <br />achieving, or attempting to achieve, the Stage 2 reduction goals and meeting the water <br />quality standard for chlorophyll -a in the Upper Lake, (iii) the existing uses in the Upper Lake <br />and whether alternative water quality standards would be sufficient to protect those existing <br />uses... ". <br />Consensus Principle #10 states: <br />"The limited resources available to DWQ [Division of Water Quality, now Division of Water <br />Resources - DWR] and DENR [Department of Environment and Natural Resources] for the <br />implementation of the nutrient management strategy and the need for a robust and active <br />sampling and monitoring program, as well as additional modeling, make it desirable for the <br />affected local governments to share resources and undertake these important activities, and <br />other activities associated with the re- examination of the Nutrient Management Strategy, <br />collectively. The affected local governments should share resources and assist with funding <br />for the examination of the Nutrient Management Strategy." <br />UNRBA Projects <br />Given the challenges with meeting Stage II of the Falls Lake Rules, as well as the guidelines <br />outlined in the Consensus Principles document, the UNRBA is already either working on, or is <br />planning to begin, the following projects: <br />• Estimation of nutrient sources and jurisdictional loading of nutrients to Falls Lake <br />• Modeling the response of Falls Lake to nutrient input and internal lake processes <br />• Monitoring of changes in the lake as a result of compliance activities in the watershed <br />• The linkage of water quality conditions to the designated uses of Falls Lake <br />• Estimation of BMP credits for measures without DWR - established credits <br />• Support of various options under the existing regulatory framework in North Carolina <br />The UNRBA has retained a consultant to help examine options for meeting the requirements of <br />Stage II the Falls Lake Rules while incorporating the goals of the Consensus Principles. <br />According to the Framework for a Re- examination of Stage 11 of the Falls Nutrient Strategy <br />prepared by the consultant, CardnoEntrix: <br />"The re- examination should consider existing data, models, nutrient management <br />strategies, the Consensus Principles, water quality standards (including designated uses <br />and water quality criteria), implementation costs, and regulatory flexibility." <br />
