This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important maintenance procedures: — The drainage area will be carefully managed to reduce the sediment load to the sand filter. — The sedimentation chamber or forebay will be cleaned out whenever sediment depth exceeds six inches. — Once a year, sand media will be skimmed. — The sand filter media will be replaced whenever it fails to function properly after maintenance. The sand filter will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. Entire BMP Trash/debris is present. Remove the trash/debris.

Provide additional erosion protection such as reinforced turf matting or riprap if needed to prevent future erosion problems. Weeds are present. Remove the weeds, preferably by hand. If a pesticide is used, wipe it on the plants rather than spraying.
