The purposes of this study were to evaluate operational and maintenance programs at municipal biological wastewater treatment facilities; identify the deficiencies in the areas of design, operation, maintenance, and administration; and to determine how the deficiencies could be overcome and operations could be improved in order to upgrade plant performance to meet standards. This report deals with the second phase of the two-part study; the findings of the first phase were published in EPA reports 600/2-79-078 and 600/2-79-034. Conclusions and recommendations of the second phase were based on comprehensive evaluations conducted at 23 treatment facilities. Of 70 potential problem areas evaluated, the ten highest ranked, based on frequency of occurrence and severity of impact, were operator application of concepts and testing to process control, sludge wasting and return, process control testing, process controllability, technical guidance for process control adjustments, industrial loading, sewage treatment understanding, adequacy of O&M manual, training, and infiltration/inflow.
