the conditions set out in section #11 (3) of the above said ECA`s.
a. A summary and interpretation of all influent and imported sewage monitoring
data, and a review of the historical trend of the sewage characteristics and

influent characteristics as well as flows, 2020 – 2022 compliance
spreadsheets attached for trending information
b. A summary and interpretation of all final effluent monitoring data, including
concentration, flow rates, loading comparison to the design objectives and
compliance limits in this approval, including an overview of the success and
adequacy of the works; - as above – the design rated capacity of 1060m3 was
exceeded a total of 8 days during 2022. The dates and flows are a result of

and objective compliance trending
i. A tabulation of the volume of sludge generated, an outline of anticipated
