Kings Beach catchment credit duration is a shorter duration due to the use of newer technologies (Jellyfish filters). This will allow TMDL program managers to reevaluate the acceptability of such technologies on a more frequent basis.

Placer County will continue maintenance of treatment BMPs within Kings Beach on an as-needed basis based on the results of the required condition assessments described above. Essential, key and supporting BMPs will be maintained by the Placer County street maintenance crew or equivalent by vactor truck, backhoe, and/or hand crew or other method necessary to remove excess sediment from the BMPs and restore infiltration/filtration function. Jellyfish filters will be visually inspected twice annually. Visual inspections will be used to identify maintenance triggers such as whether standing water exists inside the backwash pool and if sediment depth has exceed 50% of the vault depth underneath the cartridges. Filter cartridges will be rinsed and re-installed annually, at a minimum, or as necessary based on visual inspections. Sediment removal within the vaults will occur as necessary based on inspection results.
Placer County inspects all treatment BMPs within Kings Beach in accordance with the protocols described in the BMP RAM User Manual V2 (2NDNATURE 2015) or acceptable equivalent method as required by the NPDES permit. Inspections of all BMPs take place annually during spring, summer, or fall. Benchmark and threshold values for BMP condition have been set. In BMP RAM, the infiltration observation for dry basins and infiltration features offers a “User Defined” method. The California Stormwater Quality Association (CASQA) BMP Fact Sheet on infiltration basins suggests inspecting the basins 48 to 72 hours after a storm event to determine that all water has infiltrated. If all water has not infiltrated during this time period, maintenance should be performed. Placer County plans to determine the infiltration capacity of dry basins using both the CASQA suggested method along with CHP. All other BMPs will be inspected per BMP RAM protocol.
