This is a mining permit renewal without changes. There were no concerns of the renewal by DWR from WaRO, but a capacity use permit from DWR may be required if withdrawal rate exceeds 10,000 GPD. The operation would benefit from developing an O&M plan to incorporate into the SPPP documentation, although an operating plan is not required prior to continued permitting and operations (as this is a mining permit renewal, without changes). Please feel free to contact me with an questions or concerns.
