1123492	12/31/2023	CAT2	Copper, Total Recoverable Monthly Average limit is 12 ug/L and reported value was 19 ug/L at EFF-001.	In 2020, a network of structural stormwater BMPs were installed across the site and potential effects of turbulence at the discharge pump were investigated. The use of copper-based algaecides has been phased out. Dredging of the retention lake was scoped in 2023 as a potential remedy but found to be infeasible. Currently, the use of oyster shells to bind to copper in the retention lake is being evaluated. Additionally, at the request of the RWQCB on 20 January 2022, the effluent copper is monitored daily during discharge events. Refer to Annual Report section 2.4 for additional information.

1112825	12/31/2022	CAT2	Copper, Total Recoverable Monthly Average (Mean) limit is 12 ug/L and reported value was 47.3 ug/L at EFF-001.	California's Great America began evaluating the feasibility of potential remedial actions such as dredging the retention basin sediment and effluent copper treatment discharge (e.g. coagulation and filtration). At the verbal request of the RWQCB on 20 January 2022, the Discharger will monitor effluent copper daily during discharge events. The Discharger may use these data to evaluate potential remediation options.	Violation	B	eSMR

1099529	12/31/2021	CAT2	Copper, Total Recoverable Monthly Average limit is 12 ug/L and reported value was 18.1 ug/L at EFF-001.	We continue to explore effective alternatives to the copper-based algaecide used in the lake during the dry season. And as discussed over the phone with John Madigan on 20 January 2022, copper will be monitored daily during discharge events until we see copper levels return to below effluent limits for a few events. These data may also inform of other potential solutions to prevent reoccurrence, if copper levels persist.	Violation	B	eSMR

*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.
