They note the Outfall 001 location to be adjusted,which was done in the technical correction issued on
July 26,2018. UV disinfection is planned, so asking for TRC to be removed from the monitoring system
following completion of the new system. Ask to add a new weekly monitoring condition requiring a
verification of the UV lamp indicator port(indicating operation). Asked Daily monitoring be changed to
weekly. Asking for BODS,TSS,NH3-N,and Fecal Coliform to be reduced to Monthly. Permittee states

financial burden on the system operation.
