Foothill Landfill Storm Water Pollution Prevention Plan Page 53 9.0 Inspections Overview This section describes the inspections pertaining to storm water compliance issues. Refer to Appendix D for a complete list of Industrial General Permit required inspections for the San Joaquin County Foothill Landfill. 9.1 General Permit Required Inspections Inspections are performed as required by the General Permit. Monthly visual observations are performed on days with no precipitation during regularly scheduled operating hours. Sampling and visual observations events are performed for every qualifying storm event (QSE) where discharge occurs from at least one drainage area, preceded by 48 hours of no discharge from any drainage area. If safe to do so, in accordance with General Permit section XI.C.6.a.ii, sampling must be performed at every outfall with a discharge (which must occur within four hours of start of QSE discharge, or within 12 hours if a discharge started before the start of regularly scheduled business hours). A few exceptions to monitoring or monitoring reduction opportunities may apply to this facility. Refer to the Monitoring and Implementation Plan for more information. Monthly visual observations are documented on Form 2 and kept on file in San Joaquin County Foothill Landfill scale house. Sampling event visual observations are documented on Form 1 and kept on file in the Solid Waste office. More information regarding General Permit inspections can be found in the MIP. The annual evaluation is performed (normally during the month of May) to visually inspect every storm drain, outfall, and drainage area, along with any activities that occur in those areas. This annual evaluation is documented on Form 3 and kept on file in the facility office. More information regarding the annual evaluation can be found in Section 10.0.
