Attachment 2. (Continued) UNRBA Projects Given the challenges with meeting Stage II of the Falls Lake Rules, as well as the guidelines outlined in the Consensus Principles document, the UNRBA is already either working on, or is planning to begin, the following projects: • Estimation of nutrient sources and jurisdictional loading of nutrients to Falls Lake • Modeling the response of Falls Lake to nutrient input and internal lake processes • Monitoring of changes in the lake as a result of compliance activities in the watershed • The linkage of water quality conditions to the designated uses of Falls Lake • Estimation of BMP credits for measures without DWR- established credits • Support of various options under the existing regulatory framework in North Carolina The UNRBA has retained a consultant to help examine options for meeting the requirements of Stage II the Falls Lake Rules while incorporating the goals of the Consensus Principles. According to the Framework for a Re- examination of Stage 11 of the Falls Nutrient Strategy prepared by the consultant, CardnoEntrix: "The re- examination should consider existing data, models, nutrient management strategies, the Consensus Principles, water quality standards (including designated uses and water quality criteria), implementation costs, and regulatory flexibility." Water Quality Sampling During July 2014, CardnoEntrix received approval from DWR for three required technical memoranda that had been prepared and submitted for DWR review that describe in detail the watershed sampling project that will form the foundation of the re- examination process: • Quality Assurance Project Plan (QAPP) • Falls Lake Watershed Monitoring Plan • Modeling Framework The QAPP and the Monitoring Plan describe the three to five year watershed sampling effort that was initiated in August 2014. The water quality sampling program will provide information for the following purposes: • Determination of nutrient source allocation and jurisdictional nutrient loading to Falls Lake; • Falls Lake response modeling; • Development of data for consideration of additional regulatory options; and • Linkage of water quality conditions in Falls Lake to the designated uses of the Lake.
