The"Construction Sequence" calls for the stabilization of soils that remain unworked for certain lengths of time based on the time of year. Stabilization techniques may include but not limited to mulching, plastic sheeting or hydroseeding, notes have been added to the plan regarding protection for the stock pile area if necessary. 6: Protect Slopes All slopes on site during construction are required to be protected with mulch or other means as specified in the construction sequence. 7: Protect Drain Inlets CB inlet protection will be installed on all new catch basins and yard drains on and adjacent to this project. 8: Stabilize Channels and Outlets There are no channels and outlets on this project site to protect and stabilize. 9: Control Pollutants No outside chemicals are expected to be necessary for the construction of this project.All vehicles working on and around the site would need to meet the State requirements for emissions. 10: Control DeWatering DeWatering is not expected for this project. However, the detention system will be available for holding any dewatering runoff and meter release to the downstream system. 1 1 : Maintain BMPs The construction supervisor will be responsible for maintaining all BMPs during construction and working with the County to relocate or add BMPs as necessary as site conditions change. 12: Manage the Project It will be the responsibility of the Contractor and Developer to manage this project and coordinate with the City Inspector and Engineer. Inspection and Monitoring: Site inspections shall be done by a person who is knowledgeable in the principles and practices of erosion and sediment control.The person must have skills to first assess the site conditions and construction activities that could impact the quality of stormwater, and second assess the effectiveness of erosion and sediment control measures used to control the quality of stormwater discharges. Whenever inspection and/or monitoring reveals that the BMPs identified in the Construction SWPPP are-inadequate, due to the actual discharge of or potential to discharge a significant amount of any pollutant, appropriate BMPs or design changes shall be implemented as soon as possible. Maintaining an Updated Construction SWPPP: The construction SWPPP shall be retained on-site or within reasonable access to the site. The SWPPP shall be modified whenever there is a change in the design, construction, operation, or maintenance at the construction site that has, or could have, a significant effect on the discharge of pollutants to waters of the state. The SWPPP shall be modified if, during inspections or investigations conducted by the owner/operator,or the applicable local or state regulatory authority,it is determined that the SWPPP is ineffective in eliminating or significantly minimizing pollutants in stormwater discharges from the site. The SWPPP shall be modified as necessary to include additional or modified BMPs designed to correct problems identified. Revisions to the SWPPP shall be completed within seven days following inspection.
