Appendix D, cont. Estimates of (H)igh, (M)oderate, or (L)ow NPS impairment potential for sub-watersheds in the BWC Basin Group. Source categories are based on information provided by the local Soil and Water
Conservation Districts (SWCD) on Conservation Assessment Worksheets completed in 1998 and from Construction Stormwater Authorization information provided by the Mining and NPS Section of ADEM. The presence of a
CWA §303(d) stream segment within a sub-watershed raised the sub-watershed to the top of the prioritization ranking.
