7 <br /> Attachment B. Continued <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: "The re-examination should consider existing data, <br /> models, nutrient management strategies, the Consensus Principles, water quality standards <br /> (including designated uses and water quality criteria), implementation costs, and regulatory <br /> flexibility." <br /> Water Quality Sampling <br /> During July 2014, CardnoEntrix received approval from DWR for three required technical <br /> memoranda that had been prepared and submitted for DWR review that describe in detail the <br /> watershed sampling project that will form the foundation of the re-examination process: <br /> • Quality Assurance Project Plan (QAPP) <br /> • Falls Lake Watershed Monitoring Plan <br /> • Modeling Framework <br /> The QAPP and the Monitoring Plan describe the three to five year watershed sampling effort <br /> that was initiated in August 2014. The water quality sampling program will provide information <br /> for the following purposes: <br /> • Determination of nutrient source allocation and jurisdictional nutrient loading to Falls <br /> Lake; <br /> • Falls Lake response modeling; <br /> • Development of data for consideration of additional regulatory options; and <br /> • Linkage of water quality conditions in Falls Lake to the designated uses of the Lake. <br />
