CAT1 |
Total Suspended Solids (TSS) Monthly Average (Mean) limit is 30 mg/L and reported value was 31 mg/L at EFF-001A. |
Our ponds turn over in the winter leading to higher TSS levels in the make-up water which is then cycled up in the towers. ECGS will look into process remedies to avoid future violations |

Cyanide, Free Available Monthly Average (Mean) limit is 4.3 ug/L and reported value was 5.0 ug/L at EFF-001A. |
For Cyanide, ECGS believes this to be a false positive due to the sample preservation. We have contacted Babcock for clarification on what sample containers/preservatives they recommend for use in the future. |

Cyanide, Free Available Single Sample Maximum limit is 4.3 ug/L and reported value was 5.0 ug/L at EFF-001A. |
ECGS has used the new sample method OIA-1677 as implemented on the New NPDES permit. This new method has helped reduce the number of false positives, but it has not completely solved the problem. ECGS will request for cyanide sampling to be expedited with Babcock and re sample if needed to prove the false positives received |
