Maintenance will be completed annually in the Meyers registered area to ensure proper functioning condition. El Dorado County plans to inspect all key and essential treatment BMPs within the Meyers registration 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. These inspections are used to assess condition/performance and initiate maintenance. Inspections of all BMPs will take place annually during spring, summer, or fall.

Benchmark and threshold values for BMP condition have been established. These values are typically measured after snow has melted. El Dorado County completed the first round of inspections in fall 2018 to ensure that are functioning as designed. El Dorado County plans to measure the infiltration capacity of basins using CHP readings or equivalent methods. All BMPs will be inspected per BMP RAM protocols and maintained annually as needed.
