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 As 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. 13: Protect On -Site Stormwater Management BMPs for Runoff from Hard Surfaces The use of on -site management BMP's for this project will allow for the installation of the perforated stubout at the end of the project during final stabilization. That will protect those areas" from disturbance or compaction. 1n --addition, the organic content of `the amended soils will be tested and verified prior to final project acceptance. 5. SOURCE CONTROL . This project. proposes to construct a SFR and driveway. Per Volume 4 of the 2019 DOE SWMMWW, residential development does not require source control. 6. PRESERVATION OF NATURAL DRAINAGE SYSTEM The runoff from the site improvements will either be dispersed on site or tightlined to the city stormwater system. However, by not grading or compacting the majority of. the pervious surfaces "to"remain after construction -in the area of disturbance' a maximum amount of site runoff from the developed project will be absorbed and infiltrated into the existing on -site soils. This will mimic the existing conditions by maintaining the .existing direction and condition of flow from this site. Kikuchi SFR 21-0104 September 2021 Page 8
