Recent documentation of the performance of publicly owned wastewater treatment facilities has indicated that a significant percentage of facilities are not meeting design and/or permit effluent quality requirements. A research activity was implemented to identify, quantify and rank the factors limiting plant performance at thirty treatment facilities. A method (Composite Correction Programs) of improving plant effluent quality was also developed. A CCP is designed to address all factors which limit the performance of a particular facility. A CCP was implemented at the Havre, Montana Wastewater Treatment Plant and a significant improvement in plant effluent resulted which allowed permit standards to be met consistently. The potential improvement in plant performance that could be achieved if CCP's were implemented at all thirty facilities evaluated was projected. The mass of BOD5 and TSS discharged to the receiving streams would be reduced by 490 metric tons/year (540 tons/year) and 470 metric tons/year (515 tons/year), respectively.
