Sample was not collected for all parameters for the annual sampling requirement due to oversight with laboratory (the lab used the first discharge of the rainy season, typically October - April, in this case December 2019 for the 2020 annual). All quarterly requirements were met and annual data can be reported by lab for specific parameters. Additional Annual Parameters for the 1st Quarter 2020 effluent reports for the EPA 624, 625, 608, and 200.8 runs have been requested from the laboratory (that were not reported). |
Annual sampling requirements will be collected in January or the first month of flow of each year provided a flow event occurs. |
