Credit Accounting Tool Development <br />coral = agricultural enhancements, <br />olive = infrastructure enhancements, <br />—W <br />Low end estimate: Determine credits for existing BMPs in the Falls Lake watershed using previously published area <br />loading to determine loading to each BMP. Use existing credits or credits determined in 5.a. above to estimate the load <br />reduction of the BMP. Transport to the lake will not be considered. <br />High end estimate: To incorporate attenuation as nutrients are transported to the lake, develop delivery factors associated <br />with watershed impoundments (i.e., West Fork Eno River Reservoir, Lake Orange, Little River Reservoir, Lake Michie, <br />Lake Butner, Lake Rogers, and Beaverdam Impoundment) and stream channels. Delivery factors shall be based on an <br />empirical or mechanistic watershed model (e.g., WARMF or HSPF) that can also be used to estimate jurisdictional <br />nutrient load estimates. <br />Page 3 of 3 <br />
