1089345 03/03/2021 Deficient Monitoring Site flow meter was recognized to malfunction during the January annual sampling event and continuous discharge from the Site was discontinued. Flow meter was replaced and discharge recommenced on Wednesday March 3, 2021 but additional damage was identified and discharge was shut down on Tuesday March 9, 2021, before notification to the sampling team, so no sampling event was organized.

1089344 02/01/2021 Order Conditions Chronic Toxicity Test for Green Algae indicated reduced growth in the effluent sample (though still within the range of 'normal' growth) vs. the laboratory control sample, so the test result was considered toxic. This sample was collected on 2/1/2021 during a brief period of discharge initiated to collect a sample, after two weeks of no discharge. Chronic toxicity is not included in the list of either Group I or Group II pollutants, but is governed by other permit conditions. Per consultation with the RWQCB, this result is being listed as an Order Conditions violation. Violation N eSMR Sanger Sand and Gravel Plant 419656 R5-2022-0006-02 N
