(a) In order to control sediment pollution of water resources, 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 Boston Heights 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 inches (2") in diameter and placed over a geotextile fabric.
(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 with proper signage. 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: Stabilization
Area requiring stabilization | Time frame to apply erosion controls |
Any disturbed area within 50 feet of a surface water of the state 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 |
Areas at final grade | Within 7 days of reaching final grade or within 2 days of reaching final grade for areas within 50 feet of a surface water of the state |
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 on storm water catch basins located on the subject property and, if there is no threat to public safety, on curb inlets closest to the construction entrance, to minimize sediment-laden water entering active storm drain systems, including rear yard inlets.
(6) Silt Fence and Other Perimeter Controls. Silt fence and other perimeter controls approved by the Village Engineer 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 the Construction General Permit.
(7) Internal Inspection and Maintenance. All controls on the development area shall be inspected at least once every seven calendar days and within twenty-four (24) hours after any storm event greater than one-half inch of rain per twenty-four (24) hour period. Maintenance shall occur as detailed below:
A. When BMPs require repair or maintenance. If the internal inspection reveals that a BMP needs repair or maintenance, except for 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 BMPs fail to provide their intended function. If the internal inspection reveals that a BMP 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 BMPs depicted on the Abbreviated SWP3 are not installed. If the Internal inspection reveals that a BMP has not been implemented in accordance with the schedule, the BMP 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 is achieved when the site has reached seventy percent (70%) cover and when the Village Engineer approves the site condition.
(9) Notice of Termination (NOT): Once completed and inspected the contractor shall be responsible for submitting the NOT to Ohio EPA for final closure.
