I met with Randy Joseph (ORC) and Jeremy Trantham for the inspection. The center well was clear of solids, the settleability was at an acceptable level, and the rags from the bar screen are better contained now. The return lines are still shooting sludge onto the catwalk, and two of the air diffusers are still not functioning at the WWTP. These items were noted in the previous inspection and need to be repaired. The clarifier weirs still had a lot of algae on them. Mr. Joseph said he would work on cleaning those up using a hose.
