I am writing to inform you that the 3A (M-001C) monthly samples from November 4th and November 5th are missing total suspended solids (TSS) analysis. The laboratory reports from the subcontracted lab note that:
Please note, while TSS was requested on the sample, the laboratory stated there was not enough sample volume remaining in order to perform the TSS analysis. Sierra was not made aware of this issue until December 11, 2024 which did not allow them enough time to resample.
|
Collect extra sample volume for monthly samples during the use of the subcontracted laboratory. |

CAT1 |
Total Suspended Solids (TSS) Weekly Average limit is 45 mg/L and reported value was 48 mg/L at M-001C. |
In response to this event at 3A M-001C, staff immediately increased wasting, air, and bleach dosing to help remove excessive filaments. Additonally, polymer was added to help improve settling thereby preventing any further settling issues and/or exceedances. Going forward, staff has implemented the following action plan:
- Ensure microscopic analysis are performed frequently to identify filaments
- Add polymer ahead of time once settling issues are observed
- Adjust air and wasting appropriately should conditions not improve |
