Settleable Solids Instantaneous Maximum limit is 3.0 ml/L and reported value was 4.0 ml/L at EFF-001. |
Upon inspection, staff observed the mechanical sampler suction tube was laying on the floor of the effluent chamber when the high SS grab sample was collected. With the suction tube laying on the floor of the chamber, the mechanical sampler must have vacuumed up some solids resulting in the high recorded value. After this observation, the settleable solids grab sample has been taken directly from the effluent rather than through a mechanical sample device.
In addition to sampling for settleable solids directly from effluent, staff reset the mechanical sampler suction tube so it is suspended in the effluent.

It appears the gap in continuous monitoring was due to a computer update. The update automatically restarted the primary operations computer at about 3:15 AM. After the computer restarted, it did not activate the SCADA system. At 6:55 AM an operator logged onto the computer and started SCADA, thus starting continuous monitoring logging again. |
We are making every effort to correct this problem and have engaged a SCADA integrator to improve data logging redundancy and assure there is logging consistency throughout the SCADA system. |

In addition to stabilizing MBR filtrate flow to the plant effluent, staff increased flow to the MBR to boost the overall filtrate flow and improve the plant¿s effluent quality. Also, as a precaution, an off-line secondary clarifier was placed into service so the secondary clarifier that had been online could be cleaned. The primary clarifier that was online was also swapped out for a clean primary clarifier. In addition, the chlorine dose rate was increased to intensify disinfection through the chlorine contact tank. As an added step, the chlorine contact basin was thoroughly cleaned. Going forward, the plant operators will continue to regularly discuss and evaluate lab results for a variety of treatment processes with the goal of staying in compliance with the fecal coliform limits. |

As part of Table E-4 in the permit, accelerated monitoring was initiated. An additional grab sample was taken on November 6, 2019 and on November 15, 2019. The result of 93.5 mg/L was received by the contract lab on November 1st and read on November 2nd.
It should be noted that the Oil and Grease result from the sample taken on September 6th was a non-detect (ND) and the result on September 7th was 21.0 mg/L. The sample taken on November 6th was also a ND showing the treatment facility is well within permit requirements. This result appears to be an outlier. We will continue to review our sampling protocols to ensure proper collection and handling of samples.
