2. BMP Nutrient Credit Development CardnoEntrix is continuing to work on a project to develop nutrient reduction Best Management Practice (BMP) credits. The project will be beneficial to UNRBA member governments (including Orange County) by increasing the number of structural devices and other stormwater practices with known nutrient reduction values. These BMPs will then be available for affected parties to use to meet the required nutrient reduction goals under Stages I and II of the Falls Lake Rules. This is sometimes referred to as increasing the number of nutrient reduction measures available in the "BMP tool box ". Subject matter experts are developing nutrient credit values and practice standards for three "batches" of BMPs: BMP Batch 1: Infiltration Devices Filter Strips Soil Amendment BMP Batch 2: Bioretention Devices Land Conservation Pervious Area Nutrient Management Batch 3: Livestock Exclusion Riparian Buffers Elimination of Illicit Discharges After CardnoEntrix develops draft nutrient credits and practice standards for each of these BMPs, the NC Division of Water Resources (DWR) will evaluate this information and determine what nutrient reduction credit is appropriate for each BMP. Once this process is completed, affected parties, including local governments, will be able to utilize these BMPs to meet required nutrient reduction targets. 3. Development of Nutrient Credit Calculation Tool Also ongoing is the development of a spreadsheet -based tool for local governments to calculate nutrient reduction credits for specific on -site nutrient reduction measures, as well as for more regional programmatic practices such as street sweeping or fertilizer management. This tool will allow municipalities in the watershed to evaluate the impact of various nutrient reduction devices and practices at different locations in the watershed, allowing local governments to determine the most cost - effective means of meeting required nutrient reductions. 4. Falls Lake Rules Review The Regulatory Reform Act of 2013 (HB74) mandated that all State rules expire within ten years of their effective dates, unless readopted. Currently, DWR is concluding an informal comment period for the Falls Lake Rules, which will be followed in 2016 by a public comment period. UNRBA is working to develop comments on the Falls Lake Rules that all UNRBA members can agree on. Several UNRBA local governments, including Orange County, have already submitted informal comments concerning these rules.
