Appendix D cont. Estimates <strong>of</strong> (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 <strong>Water</strong><br />

Conservation Districts (SWCD) on Conservation Assessment Worksheets completed in 1998 and from Construction Stormwater Authorization information provided by the Mining and NPS Section <strong>of</strong> ADEM. The presence <strong>of</strong><br />

a CWA §303(d) stream segment within a sub-watershed raised the sub-watershed to the top <strong>of</strong> the prioritization ranking.<br />
