(a) In order to control sediment pollution of water resources, the owner shall submit an Abbreviated SWP3 in accordance with the requirements of this regulation.
(b) The Abbreviated SWP3 shall be certified by a professional engineer, a registered surveyor, certified professional erosion and sediment control specialist, or a registered landscape architect.
(c) The Abbreviated SWP3 shall be certified by a Registered Professional Engineer, a Registered Professional Surveyor, certified Professional Erosion and Sediment Control Specialist, or a Registered Landscape Architect.
(1) Construction Entrances: Construction entrances shall be built and shall serve as the only permitted points of ingress and egress to the development area. These entrances shall be built of a stabilized pad of aggregate stone or recycled concrete or cement sized greater than 2" in diameter, placed over a geotextile fabric, and constructed in conformance with specifications in the most recent edition of the Rainwater and Land Development Manual.
(2) Concrete Truck Wash Out: The washing of concrete material into a street, catch basin, or other public facility or natural resource is prohibited. A designated area for concrete washout shall be indicated on the plan. Use for other waste and wastewater is prohibited.
(3) Street Sweeping: Streets directly adjacent to construction entrances and receiving traffic from the development area, shall be cleaned daily to remove sediment tracked off-site. If applicable, the catch basins on these streets nearest to the construction entrances shall be cleaned weekly.
(4) Stabilization. The development area shall be stabilized as detailed in Table 4.
Table 4: Permanent Stabilization
Area requiring stabilization
Time frame to apply erosion controls
Any disturbed area within 50 feet of a surface water of the state stream and not at final grade.
Within 2 days of the most recent disturbance if that area will remain idle for more than 14 days
For all construction activities, any disturbed area, including soil stockpiles, that will be dormant for more than 14 days but less than one year, and not within 50 feet of a stream.
Within 7 days of the most recent disturbance within the area
Disturbed areas that will be idle over winter
Prior to November 1.
Note: Where vegetative stabilization techniques may cause structural instability or are otherwise unobtainable, alternative stabilization techniques must be employed. These techniques may include mulching or erosion matting.
(5) Inlet Protection. Erosion and sediment control practices, such as boxed inlet protection, shall be installed to minimize sediment-laden water entering active storm drain systems, including rear yard inlets. Straw, or hay bales, and filter socks around an inlet are not acceptable forms of inlet protection.
(6) Silt Fence and Other Perimeter Controls. Silt fence and other perimeter controls approved by the Village shall be used to protect adjacent properties and water resources from sediment discharged via sheet (diffused) flow. Silt fence shall be placed along level contours and the permissible drainage area is limited to those indicated in Table 3 in 971.09 of these regulations.
(7) Internal Inspection and Maintenance. All controls on the development area shall be inspected at least once every seven calendar days and within 24 hours after any storm event greater than one-half inch of rain per 24 hour period. Maintenance shall occur as detailed below:
A. When SCMs require repair or maintenance. If the internal inspection reveals that a SCM is in need of repair or maintenance, with the exception of a sediment-settling pond, it must be repaired or maintained within three (3) days of the inspection. Sediment settling ponds must be repaired or maintained within ten (10) days of the inspection.
B. When SCMs fail to provide their intended function. If the internal inspection reveals that a SCM fails to perform its intended function and that another, more appropriate control practice is required, the Abbreviated SWP3 must be amended and the new control practice must be installed within ten (10) days of the inspection.
C. When SCMs depicted on the Abbreviated SWP3 are not installed. If the internal inspection reveals that a SCM has not been implemented in accordance with the schedule, the control practice must be implemented within ten (10) days from the date of the inspection. If the inspection reveals that the planned control practice is not needed, the record must contain a statement of explanation as to why the control practice is not needed.
(8) Final Stabilization: Final stabilization shall be determined by the Village Engineer.
