4: Install Sediment Controls <br /> This site SWPPP proposes to construct/maintain a gravel entrance (BMP C105), <br /> vegetative buffer (BMP C102), silt fencing (BMP C233) and retention of the existing <br /> vegetation (BMP C101) that will provide a vegetated strip around the work area and any <br /> adjacent property line. The construction of these features should be completed before the <br /> clearing and grading of the site. Mulch (BMP C121) may also be used on the exposed soil <br /> as necessary to limit erosion. In addition, streets shall be cleaned as needed at the end of <br /> each workday or throughout the day if dirt and debris is tracked onto the paved surFaced. <br /> 5: Stabilize Soils <br /> The "Construction Sequence" calls for the stabilization of soils that remain unworked for <br /> certain lengths of time based on the time of year. Bare/disturbed soils shall remain <br /> uncovered or un-stabilized for no more than 2 days from Oct. 1 — April 30 and no more <br /> than 7 days from May 1 — Sept. 30. Stabilization techniques may include but not limited <br /> to mulching (BMP C121), plastic sheeting (BMP C123) or hydroseeding (BMP C120), <br /> notes have been added to the plan regarding protection for the stock pile area if <br /> necessary. A stockpile area has been identified on the SWPPP and is setback a minimum <br /> of 25-feet from any down slope property line. In addition, during dry periods soil should be <br /> covered or wetted (BMP C140) to reduce the production of dust. <br /> 6: Protect Slopes <br /> All disturbed slopes on site during construction are required to be protected with mulch <br /> (BMP C121) or other means as specified in the construction sequence like surface <br /> roughening (BMP C130). No concentrated runoff or significant amounts of sheet flow will <br /> be directed to new cut or fill slopes during construction (BMP C206). <br /> � <br /> ' 7: Protect Drain Inlets <br /> No new or existing inlets are proposed or present on or around this site. <br /> 8: Stabilize Channels and Outlets <br /> No existing channels or outlets are present on or around this site. <br /> 9: Control Pollutants <br /> No outside chemicals are expected to be necessary for the construction of this project. <br /> Concrete truck chutes, pumps, internals and hand tools shall be washed out only into <br /> formed areas awaiting installation of concrete or asphalt. Unused concrete remaining in <br /> the truck and pump shall be returned to the originating batch plant for recycling. When no <br /> formed areas are available, washwater and leftover product shall be contained in a lined <br /> container and disposed of in a manner that does not violate water quality standards. All <br /> vehicles working on and around the site would need to meet the State requirements for <br /> emissions. A drip pan or other appropriate temporary containment device shall be placed <br /> at locations where leaks or spills may occur during the fueling or maintenance of <br /> machinery. <br /> Haack—Lexington Duplex 16-1112 <br /> January 2017 Page 7 <br />
