Sediment shall not be removed with water, and all sediment must be disposed of as frll on -site or hauled off -site. 2. Any sediment In the catch basin insert shall be removed when the sediment has filled one-third of the owilab/e storage. The filter media for the insert shall be cleaned or rep/aced of least monthly. 3. Regular maintenance is critical for both forms of catch basin protection. Unlike many forms of protection that fail gradually, catch basin protection will foil suddenly and completely if not mointdined properly.
