Violation N eSMR Stevens Creek Quarry 443276 R2-2021-0010 N 1139648 10/11/2024 Order Conditions The discharge of untreated process water from Sediment Trap 3 affected water quality in Swiss Creek during RWQCB inspection was observed on October 11, 2024. The RWQCB observed sediment in the tributary from Discharge Point 004 and foam and aquatic growth downstream of the tributary that was not visible upstream. Permit receiving water limitations V.A.1 and V.A.4 prohibit discharges from causing floating materials (foams, scum), bottom deposits, and aquatic growths that affect the beneficial uses of receiving waters.

Violation N eSMR Stevens Creek Quarry 443276 R2-2021-0010 N 1139645 11/25/2024 Deficient Monitoring On November 25, SCQ collected an acute toxicity sample at EFF-004, which followed the proper sampling technique and occurred under normal ATS operating conditions. On November 26, 2024, discharge ceased from EFF-004. On November 27, SCQ was notified by the laboratory via email, that it did not conduct the acute toxicity test due to using the wrong sample for testing. Therefore, the original sample extended beyond the 36-hour hold time and the acute toxicity test could not be completed.
