The Doe Run Resources Co. requested Section 401 Water Quality Certification accompany the U.S. Army Corps of Engineers' (USACE) Nationwide Permit 38 for "Cleanup of Hazardous and Toxic Waste", which would cover multiple locations under the Doe Run Viburnum Trend Aquatic Restoration Project. The project includes remedial sediment removal at various locations from five jurisdictional streams located within various areas of the Viburnum Trend. Three streams proposed for sediment removal (Big Creek, West Fork Crooked Creek and Crooked Creek) exist within the St. Louis USACE Regulatory District, and two streams (Adair Creek and Sweetwater Tributary) exist within the Little Rock USACE Regulatory District. Proposed plans include excavating sediment from specific locations on each stream to remove lead from the aquatic environment, requiring temporary crossings and entry/ exit points on streambanks. The project will be governed by the Sediment Excavation Master Plan (SEMP) for the Viburnum Trend Aquatic Restoration and will include 80 linear feet of temporary stream crossing impacts, 640 linear feet of temporary stream entry/ exit impacts and 2,485 linear feet of gravel bar sediment removal.
