1140781 10/25/2023 OEV pH Instantaneous Minimum limit is 6.5 SU and reported value was 6.26 SU. Violation B Report
1140793 10/25/2023 Surface Water pH Instantaneous Minimum limit is 6.5 SU and reported value was 6.25 SU for RSW-001D. In addition, the pH was changed more than 0.3 units from RSW-001U with a reported value of 6.61. The pH reported value for effluent on 10/25/2023 was 6.26, which is out the effluent limits of 6.5 to 8.3 standard units. Violation B Report
1118680 04/30/2023 CAT1 Total Suspended Solids (TSS) Monthly Average (Mean) limit is 10 mg/L and reported value was 16 mg/L at EFF-001. The effluent TSS had returned to normal by the May 2023 sampling event. Violation U eSMR
1116053 03/28/2023 CAT1 Total Suspended Solids (TSS) Daily Maximum limit is 20 mg/L and reported value was 25 mg/L at EFF-001. We have reviewed site operations and have not identified any changes or unusual operational events. The TSS exceedance appears to be related to the same series of storm events driving high receiving water turbidity. We are conducting follow up sampling to assess whether solids in onsite ponds have settled out. Violation U eSMR
1116052 03/28/2023 CAT1 Total Suspended Solids (TSS) Monthly Average (Mean) limit is 10 mg/L and reported value was 25 mg/L at EFF-001.

1140794 09/21/2022 Surface Water The pH reported value was 8.04 SU for RSW-001D. The pH was changed more than 0.3 units from RSW-001U with a reported value of 7.12. The pH reported value for effluent on 09/21/2022 was 5.96, which is out the effluent limits of 6.5 to 8.3 standard units. Violation B Report

1140792 08/30/2021 OEV pH Instantaneous Minimum limit is 6.5 SU and reported value was 5.26 SU. Violation B Report
1095704 08/30/2021 CAT1 Total Suspended Solids (TSS) Monthly Average limit is 10 mg/L and reported value was 13 mg/L at EFF-001. The Site has not discharged since 8/31/2021 due to facility water needs. When facility discharge re-initiates, TSS values will be sampled and monitored for permit compliance. Review of historical site TSS data and current turbidity data do not indicate a chronic problem with TSS. No discoloration was noted at the time of sample collection. Violation U eSMR
1089345 03/03/2021 DMON 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. Flow meter has now been repaired again. Discharge recommenced in April and April's monthly sampling event has occurred. Violation U eSMR
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. Per permit conditions, discharger has initiated accelerated monitoring for chronic toxicity (first sample collected 4/27/2021). Discharger will collect 4 accelerated monitoring samples to assess Green Algae chronic toxicity. Per consultation with the Regional Board, initiation of the accelerated monitoring was held until the Site entered a period of continuous discharge again, rather than activating the discharge only to collect a sample.

*Click the "(+/-) Violation Description" link to expand and contract the violation description.
*As of 5/20/2010, the Water Board's Enforcement Policy requires that all violations be classified as 1, 2 or 3, with class 1 being the highest. Prior to this, violations were simply classified as Yes or No. If a 123 classification has been assigned to a violation that occurred before this date, that classification data will be displayed instead of the Yes/No data.
