Meeting Summary Patrick Beggs (DWR) opened the meeting with introductions and a review of the agenda. The Oct 4, 2019 meeting summary was approved. Falls Lake Nutrient Management Strategy & UNRBA Re-examination Alix Matos, of Brown and Caldwell, and Forrest Westall of the Upper Neuse River Basin association, presented on the Falls Lake Nutrient Strategy and Re-examination including Monitoring Loading to the lake, Data Analysis, Modeling, and an Alternative Implementation Approach for Stage I Falls Existing Development Rule. The presentation can be found online. Data can be found at http://monitor.unrba.org. NSAB – October 4, 2019 2 of 2 The following is a summary of questions and comments during the presentation. • 2007 was the worst year of drought. Nitrogen deposition has decreased greatly since 2007. • Monitoring and modeling captures lake sediment but not legacy sediment form upstream. • USACE did not amend the soil before the lake was filled. • Alternative approach: o Seems to be many benefits, including cooperation across sectors. o Concerned about collaborative enforcement and financial responsibility. o Need to be sure to give credit for any investment in Existing development ahead of implementation. o Need to remember this a pilot study. o Still many details to work out at this point including, construction costs, operation and maintenance, in-kind service, larger governments being agents for smaller governments if needed. • Everything learned in Falls can be used in Jordan and vice versa. • Modeling and monitoring costs are being paid for by UNRBA dues. • USACE lake operations are a very important aspect of rule implementation, communication and planning. We all need to work to continue to develop hat relationship throughout NC. Updates and Comments • Street Sweeping and Storm Drain Cleaning Nutrient Credit Practices have been approved. • Please have a JLOW update at each meeting. • Rain in the past 15 months has made local flooding a huge concern. Any way we can tie reducing flooding to water quality will help get buy-in for future actions. • Agree with the flooding comment – no one is talking about water quality, just flooding. • DOT has an established research program. Maybe NSAB can keep a running inventory of research needs. • Practices are designed to treat the 1 inch storm, but most nutrient loading comes from storms greater than 1 inch. The NSAB will meet January 3, 2020, 9:30 am at TJCOG.
