Areas not at final grade that will remain dormant longer than 30 days must have temporary soil stabilization within seven days. Areas that will be dormant longer than one year must have permanent soll stabilization. All soil stockpiles and borrow areas must be stabilized and borrow areas must be stabilized or protected with sediment trapping measures. Temporary protection and permanent stabilization shall be applied to all on-site soil stockpiles and borrow areas and soil intentionally transported from the project site. Permanent vegetative cover shall be established on denuded areas not otherwise permanently stabilized. Permanent vegetation shall not be considered established until a ground cover is achieved that is uniform, mature enough to survive, and will inhibit erosion. Sediment basins and traps, and perimeter ESC measures intended to trap sediment must be constructed as a first step in any land­ disturbing activity and shall be made functional before upslope land disturbance takes place. Cut and fill slopes must be designed and constructed in a manner that will minimize erosion. Slopes that are found to be eroding excessively within one year of permanent stabilization shall be provided with additional slope stabilizing measures until the problem is corrected. Concentrated runoff shall not flow down cut or fill slopes unless contained within an adequate temporary or permanent channel, flume, or slope drain structure. Whenever water seeps from a slope face, adequate drainage or other protection must be provided. Inlet protection is required for all storm inlets that will be made operable during construction. Before newly constructed storm water conveyance systems are made operational, adequate outlet protection and any required channel lining must be Installed in both the conveyance channel and receiving channel. MS-10 Underground utility lines shall be installed in accordance with the following standards in additions to other applicable criteria: a. No more than 500 linear feet of trench may be opened at one time. b. Excavated material shall be placed on the uphill side of trenches. c. Effluent from dewatering operations shall be filtered or passed through an approved sediment trapping device, or both and discharged so that is does not adversely affect flowing streams or off·slte property. d. Material used for backfilling trenches shall be properly compacted in order to minimize erosion and promote stabilization. e. Re·stabilization shall be accomplished in accordance with these regulations. f. Comply with all applicable safety regulations. MS-11 Construction entrances are required at all access points to the construction site. Where sediment is transported onto a paved or public road surface, the road surface shall be cleaned thoroughly at the end of each day. Sediment shall be removed from the roads by shoveling or sweeping and transported to a sediment control disposal area. Street washing shall be allowed only after sediment is removed in this manner. This applies to individual development lots as well as to larger land-disturbing activities. MS-12 All temporary erosion and sediment control measures shall be removed within 30 days after final site stabilization or after the temporary measures are no longer needed, unless otherwise authorized by the local program authority. Trapped sediment and the disturbed soil areas resulting from the disposition of temporary measures must be permanently stabilized to prevent further erosion and sedimentation. Any variance to the above listed minimum standards must be requested and approved in writing. UTILITY NOTICES All excavated material is to be placed on the uphill side of trench. All storm and sanitary sewer lines not in streets are to be mulched and seeded within 7 days after backfill. No more than 500 feet of trench is to be open at one time. Construction access roads shall be located on the uphill side of the trench or over the trench whenever possible. All construction discharge water shall be adequately filtered to remove silt prior to discharge into waterways and wetlands. Material used for backfilling trenches shall be properly compacted in order to minimize erosion and promote stabilization. All work must be in compliance with applicable safety regulations. SILT FENCE NOTES Silt fence and filter fabric must be entrenched. Posts for silt fences shall be either 2-inch diameter oak,4·inch diameter pine or 1.33 pounds per linear foot steel. Posts will be a minimum of 5 feet in length. Steel posts shall have projections for fastening wire to them. Wire fence reinforcement for silt fences using standard strength filter cloth shall be a minimum of42 inches in height, a minimum of 14 gauge and shall have a maximum mesh spacing of 6 inches. Post shall be spaced a maximum of 10 feet apart at the barrier location and driven securely into the ground (min. of 12 inches) when extra strength fabric is used. Without the wire support fence, post spacing shall not exceed 6 feet. When extra strength filter fabric and closer post spacing are used, the wlre mesh support fence may be eliminated. In such a case, the filter fabric is stapled or wired directly to the post. Sediment must be removed when deposits reach approximately one-half the height of the barrier. Any sediment deposits remaining in place after the silt fence or filter barrier ls no longer required shall be dressed to conform with the existing grade, prepared, and seeded. Under no circumstances should silt fence be installed in live streams. Silt fence shall be removed upon completion of the project. SEEDING NOTES All stabilization/seeding will be accomplished in accordance with the Indiana Storm Water Quality Manual. Any disturbed area not paved, sodded, or built upon, will have a vegetative cover prior to final inspection, and in the opinion of the Engineer will be mature enough to control soil erosion satisfactorily and survive severe weather conditions. Stream diversion areas, waterways, banks and related areas will be seeded and mulched immediately after work in watercourse is completed. In no case shall wetland areas be reseeded with any species of fescue. Winterization - any disturbed area not paved, sodded, or built upon by October 15 is to be seeded and mulched on that date unless waived by the Engineer. Permanent or temporary soil stabilization shall be applied to denuded areas within seven (7) days after final grade is reached on any portion of the site. Temporary soil stabilization shall be applied within seven (7) days to denuded areas that may not be at final grade, but will remain dormant for longer than thirty (30) days. Permanent stabilization shall be applied to areas that are to be left dormant for more than six (6) months. Electric power, telephone, and gas supply trenches must be compacted, seeded, and mulched within 7 days after backfill. All temporary earth berms, diversions, and silt dams are to be mulched and seeded for vegetative cover immediately after grading. Straw or hay mulch is required. The same applles to all stockpiles, on site as well as soil (intentionally) transported from the project site. Nutrients shall be applied ln accordance with manufacturer's recommendations or an approved nutrient management plan and shall not be applied during rainfall events.
