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.	Violation	N	eSMR	Stevens Creek Quarry	443276	R2-2021-0010	N
