After the sand filter is established, it shall 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 shall be kept in a known set location and shall be available upon request. Inspection activities shall be performed as follows.
