Order Conditions |
The Discharger violated the Filtration System Operating Specifications for turbidity contained in the WDRs, as shown in Table C. The Discharger reported exceedances of the maximum daily average value of 2 Nephelometric Turbidity Units (NTU) on seven days in late-April 2024. The Discharger suspects the increased turbidity was caused by the seasonal change in temperature and consequent effect on the Facility¿s biological treatment process. Turbidity was restored to levels compliant with the WDRs on 26 April 2024. |
