Table 2 <br />Routine Maintenance Activities for Non -Proprietary Media Filters <br />No. <br />Maintenance Task <br />Frequency of Task <br />1 <br />Inspect for standing water, sediment, trash and debris. <br />Monthly during rainy season <br />2 <br />Remove sediment, trash and debris from sedimentation <br />As needed <br />basin, riser pipe and filter bed. Dispose of sediment, trash <br />and debris properly. <br />3 <br />Ensure that non-proprietary media filter drains completely <br />After major storm events and as <br />within five days. <br />needed. <br />4 <br />For non-proprietary media filters with a filter bed, inspect <br />Monthly during rainy season, or as <br />media depth to ensure proper drainage. <br />needed after storm events <br />5 <br />Inspect non-proprietary media filter using the attached <br />Monthly, or after large storm events, <br />inspection checklist. <br />and after removal of accumulated <br />debris or material <br />It. Prohibitions <br />The use of pesticides and quick release fertilizers shall be minimized, and the principles of integrated <br />pest management (IPM) followed: <br />1. Employ non -chemical controls (biological, physical and cultural controls) before using <br />chemicals to treat a pest problem. <br />2. Prune plants properly and at the appropriate time of year. <br />3. Provide adequate irrigation for landscape plants. Do not over water. <br />4. Limit fertilizer use unless soil testing indicates a deficiency. Slow-release or organic <br />fertilizer is preferable. Check with municipality for specific requirements. <br />5. Pest control should avoid harming non -target organisms, or negatively affecting air and <br />water quality and public health. Apply chemical controls only when monitoring indicates <br />that preventative and non -chemical methods are not keeping pests below acceptable <br />levels. When pesticides are required, apply the least toxic and the least persistent <br />pesticide that will provide adequate pest control. Do not apply pesticides on a <br />prescheduled basis. <br />6. Sweep up spilled fertilizer and pesticides. Do not wash away or bury such spills. <br />7. Do not over apply pesticide. Spray only where the infestation exists. Follow the <br />manufacturer's instructions for mixing and applying materials. <br />8. Only licensed, trained pesticide applicators shall apply pesticides. <br />9. Apply pesticides at the appropriate time to maximize their effectiveness and minimize the <br />likelihood of discharging pesticides into runoff. Wth the exception of pre -emergent <br />pesticides, avoid application if rain is expected. <br />10. Unwanted/unused pesticides shall be disposed as hazardous waste. <br />Standing water shall not remain in the treatment measures for more than five days, to prevent <br />mosquito generation. Should any mosquito issues arise, contact the San Mateo County Mosquito <br />Abatement District (SMCMAD), as needed for assistance. Mosquito larvicides shall be applied only <br />when absolutely necessary, as indicated by the SMCMAD, and then only by a licensed professional <br />or contractor. Contact information for SMCMAD is provided below. <br />Trees and other large vegetation shall be prevented from growing adjacent to the non- <br />proprietary media filter to prevent damage. <br />ATTY/AGR/2019.061/MP BRADFORD ASSOCIATES, L.P., - STMMA EXHIBIT C <br />REV: 0320.19 PR Page 2 of 8 <br />
