Does the waste water treatrment plant log events which exceed design flow limits?

Does the waste water treatment plant operator log events which exceed these limits (excerpt from the WWTP Facilities Master Plan prepared by Black & Veatch in 2003 contains design parameters of the plant - see Q 2.16)?
If so, what is the recent history (last several years)? Please provide summaries of events when any of these limits were exceeded. I am also interested in learning more about situations described in the response to Q2.16: ”...typically because plant flow increases faster than plant operators can react to bring equipment on-line that is not needed at the lower flow rates….” 
This is to understand how issues involving wet weather events at the WWTP are related to plant capacity, or other parameters, such as rate of change in flowrates or other operational challenges.
This question is excerpted and adapted from a comment on question 2.16
Thanks
Joe
