The PLC (photograph in Appendix A) also displays variable versus <br />time graphs which aid in real-time visualization of changes to the system, assisting the operator to make <br />quick changes to the system if/when necessary. All measurement data and graphs are viewable remotely <br />via the Walchem Fluent website. Additional changes and features are programable on the PLC, and <br />additional meters and measurements will be displayed upon their installation. These upgrades will <br />provide additional data collection points and aid in making changes to the system quickly and as needed. <br />Alarm features have also been programed into the PLC, which send a text message and email to alert the <br />operators in the case that urgent changes must be made. <br />The pilot Plant described above has been fully operational and since the installation of continuous 24/7 <br />treatment from December 15, 2021, through the last compliance sample reported in March, has produced <br />consistent results that are 100% in compliance samples with GIR’s discharge permit (Table 2). The pilot <br />system in place has proven to be successful, and GIR will continue to make improvements and upgrades <br />to the system as needed. GIR is committed to meeting compliance standards and looks forward to <br />working with the State in the future to ensure success for the future. <br />Table 2 <br /> <br />
