(a)   In order to control sediment pollution of water resources and wetlands, the applicant 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 include a minimum of the following BMPs. The Village of Westfield Center may require other BMPs as site conditions warrant.
      (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 two inch 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 made available.
      (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.
Any disturbed area within 50 feet of a stream and not at final grade.
Within two 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 with 50 feet of a stream.
Within seven days of the most recent disturbance within the area.
Disturbed areas that will be idle over winter.
Prior to November 1st.
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. Straw or hay bales are not acceptable forms of inlet protection.
      (6)   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 practices require repair or maintenance: If the internal inspection reveals that a control practice is in need of repair or maintenance, with the exception of a sediment-settling pond it must be repaired or maintained within three days of the inspection. Sediment settling ponds must be repaired or maintained within ten days of the inspection.
         B.   When practices fail to provide their intended function: If the internal inspection reveals that a control practice 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 days of the inspection.
         C.   When practices depicted on the Abbreviated SWP3 are not installed: If the internal inspection reveals that a control practice has not been implemented in accordance with the schedule, the control practice must be implemented within ten 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.
      (7)   Final stabilization: Final stabilization shall be determined by the Village Engineer.
