SOIL SURFACE EROSION CONTROL

08/08

PART 1 GENERAL

1.1 SUMMARY OF WORK

The work consists of furnishing and installing temporary and permanent soil surface erosion control materials to prevent the pollution of air, water, and land, including fine grading, mulching, vegetative measures, structural measures, and miscellaneous related work, within project limits and in areas outside the project limits where the soil surface is disturbed from work under this contract at the designated locations. This work includes all necessary materials, labor, supervision and equipment for installation of a complete system. Submit a listing of equipment to be used for the application of erosion control materials. Prior to the initiation of any permitted construction activities, a sedimentation barrier shall be constructed immediately down gradient of the construction site.

Sedimentation barriers shall be specifically designed to handle the sediment type and load of the construction site throughout the anticipated time of construction and unstable site conditions. The sedimentation barrier shall be maintained in good working order throughout the duration of the project. Upon project completion, the accumulated materials shall be removed and disposed of at a type 2 landfill site (non-wetland, non-floodplain) site and stabilized with seed and mulch. The sedimentation barrier shall then be removed in its entirety and the area restored to its original configuration and cover. All raw areas in uplands resulting from the permitted construction activity shall be effectively stabilized with sod and/or seed and mulch (or other technology specified by this permit or project plans) in a sufficient quantity and manner to prevent erosion and any potential siltation to surface waters or wetlands. Temporary stabilization measures shall be installed before or upon commencement of the permitted activity, and shall be maintained until permanent measures are in place. Permanent measures shall be in place within five (5) days of achieving final grade. All fill/backfill shall consist of clean inert material that will not cause siltation nor contain soluble chemicals, pollutants, or contaminants. All fill placed on the DNR Harley Ensign boating site shall be contained in such a manner so as not to erode into any surface water, flood plain, or wetland. Planting of the site will occur in the spring of 2018, all finished upland areas associated with the permitted activity shall be stabilized with sod and/or seed and mulch, riprap, or other technically effective methods as necessary to prevent erosion. All raw earth within 100 feet of a lake, stream, or wetland that is not brought to final stabilization by the end of the active growing season shall be temporarily stabilized with mulch blankets in by 10 October 2017. Refer to MDEQ Permit attached to SECTION 01 99 90 LISTING OF ENCLOSED DOCUMENTS, EXHIBITS AND OTHER ATTACHMENT. Turbidity curtain will only be required if the contractor's activities to plant the Great Lakes Marshes areas will create a significant disturbance to the existing fill material , such as using construction or landscaping equipment for the planting work.
