The purpose of the evaluation was to verify that the facility is operating in compliance with the conditions and limitations specified in Permit WQ0009267. William Brown, ORC, and Amy Palaschak, Supervising Chemist, were present during the inspection. The City of Jacksonville WWTF consists on a three -train, multi -cellular biological treatment lagoon system and a 7400 acre wooded irrigation site. The City is permitted for 9,000,000 gpd and is averaging 5,000,000 gpd. Each train consists of a 4.5 MG cell with four aerators followed by 3 MG cell with curtain baffle and 14 Blue Frog floating mixers. In 2018, the City installed the Blue Frog mixers in all three trains, after a pilot study in 2016, to reduce solids. Staff indicated that the solids level in the lagoons is accumulating at a slower rate and they predict the frequency of solid removal will decrease. The City had exceeded their application rates in 2018 due to the effects of Hurricane Florence and the need to activate their Emergency Action Plan for reduction of stored effluent in the combined EasVWest Storage Lagoon and the South Storage Lagoon. Since that time, the City has taken steps to address these issues and has been in compliance for over a year. Forestry management activities are continuous, to include cutting and clearing fields damaged during Hurricane Florence. Equipment has been purchased that allows staff to move fallen trees without damaging field conditions as they maintain the irrigation site. Culverts and ditches on irrigation site have been cleaned to allow stormwater to flow as designed. Irrigation strategies have been identified to improve distribution of monthly application. The facility is compliant with Non -Discharge Permit WQ0009267. Please review the comment sections of the inspection report for more details.
