Element is not applicable. SWPPP Element 9: Control Pollutants Due to the size of the project, this is not anticipated to be a significant issue. SWPPP Element 10: Control Dewatering Because of the soils and lack of groundwater in the depth of excavations proposed, there should be no need for significant, if any, dewatering. SWPPP Element 11: Maintain BMPs Notes will be included on the SWPPP for maintenance of BMPs. SWPPP Element 12: Manage the Project Due to the disturbance area of approximately 1.5 acres, a Certified Erosion and Sedimentation Control Lead (CESCL) is required. The CESCL shall be identified at the pre-construction conference and shall retain current Washington State CESCL certification until all TESC BMPs have been removed from the project site. Notes are included on the TESC plan for inspection, maintenance, construction sequencing, and reporting on SWPPP measures. SWPPP Element 13: LID Protection during Construction The stormwater management facility shown on the plan (infiltration trench/pit) shall be protected during construction. This shall include protection from sedimentation in the facilities and compaction of the subsurface soils. Construction equipment shall be kept off of these facilities to retain infiltration capacity of the existing subsurface soils. Any sediment that accumulates within these facilities during construction shall be completely removed with excavation to the bottom of these facilities, to provide a clean and undisturbed existing soil. The inlet pipe to the infiltration facility shall not be connected to the facility until the site has been fully stabilized, to prevent sediment from entering the infiltration area.
