10: Control DeWatering DeWatering may be necessary for this project. However, the existing vegetation retained on site would be available to spread any water from construction for filtration and disposal (BMP C236). 11: Maintain BMPs The construction supervisor will be responsible for maintaining all BMPs during construction and working with the City to relocate or add BMPs as necessary as site conditions change (BMP C150). BMPs should be inspected and maintained as needed after every rain event producing more than %" of rain in a 24-hour period. Also, BMPs shall be inspected on a weekly basis even if site work is not occurring. 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 short plat. 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. (BMP C150 & C162) • •13:.Protect-On-Site..Stormwater Management BMPs for Runoff from Hard Surfaces The use of infiltration BMPs for this project will allow for the installation of these features at the end of the project during final stabilization. That will protect those areas from disturbance or compaction. In addition, the organic content of the amended soils will be tested and verified prior to final project acceptance.
