15 The site uses the following post-construction BMPs: Painted Storm Drain Inlets. All storm drain inlets in the project site shall be painted with the following logo "Dump no Waste - Drains to Bay." This educational measure is intended to prevent unlawful dumping of waste materials, such as motor oil, into the storm drains. Vacuum Sweeping of Parking Lot (weekly): In order to minimize sediments, metal pollutants, oil and grease going into the storm drain system, the owner shall sweep the parking lots every week to prevent accumulation of these pollutants. The frequency of vacuum sweeping makes this the most effective BMP to prevent sediment building up in the storm drain system. SECTION 4 - BMP INSPECTION, MAINTENANCE, AND RAIN EVENT ACTION PLANS SECTION 4.1 - BMP INSPECTION AND MAINENTANCE The General Permit requires (Attachments C; Section G.5) that completed inspection checklists be maintained with the on-site SWPPP. In general the information required to be recorded for BMP/facility inspections includes: the date of the inspection, weather information, site information, observations, descriptions of the inspected BMPs and any deficiencies, and the corrective actions that were taken such as BMPs that were fixed or additional BMPs that were implemented, and the inspectors name, title, and signature. The required frequency of BMP inspections depends on the type of BMP that is implemented. The General Permit (Attachments C; Section G.2) requires routine weekly inspections and daily inspections during rain events of all BMPs (for all Risk Categories). BMPs must be maintained regularly based on permit-required inspections and observations during the course of normal construction activities. The General Permit requires dischargers to begin implementing corrective actions within 72 hours for deficiencies identified during inspections (Attachments C; Section G.3). SWPPP amendments should be prepared by the QSD if warranted by the problem encountered and corrective action required. While many of the storm water pollution control measures discussed in Section 4 relate to practices, some are actually structural controls, which to function properly, require ongoing inspection, maintenance, and repair. Table 4 below outlines procedures to ensure that all grade surfaces and storm water management measures identified within this SWPPP are maintained in good and effective condition and are promptly repaired or restored.
