Slope has been graded. Sediment barriers are now below water level. Needs to be re-vegetated. Not ready for final.

Conference call with Knife River (Jeff),Dave Powell, Clint Smith and Steve Webb. Discussed dewatering issues on site. It was agreed to allow an additional basin to be dug to expand storage capacity. A request was made to allow water to be released into the wetlands after sediment was allowed to settle in the basin (with baffles) and then have the water be released from the basin through a series of bmp's to trap additional sediment prior to entering the wetlands. D. Powell had been in tough with G. Howard (Wetlands Group) regarding using the wetlands as a final avenue to reduce turbidity. S. Webb request written approval from U. S. Army Corp of Engineers (USCOE) prior to using the wetlands for treatment of sediment prior to water being released of site. Overall conclusion was made that acceptable water quality according to the State of Idaho standards should be achieved. It was recommended to monitor turbidity with a turbidity meter throughout the project after determining background. Stop work is lifted to allow extra controls and bmps to be implemented, overall concern it that release of water leaving the site is meeting water quality standards.
