RADIUS FAQ's for Emission Statement

Q1: What is Source Details and when should it be reported?
A1: Source Details is detailed information such as type of fuel, sulfur content of the fuel, VOC content of the ink or coating, size of tank, and content in the tank. Source Details should be reported for all combustion sources, printing presses, surface coating operations, and storage tanks. In RADIUS, the Source Details button is located in the Emission Statement section, at the bottom left-hand corner of the Emissions screen. This button activates the window for filling out this information.

Q2: What is Control Operations and when should it be reported?
A2: Control Operations is control device information such as operating time and capture, removal, and overall efficiencies. Control Operations should be reported for all operating scenarios that have a control device associated to it, as indicated in the Emission Unit/Batch Process Inventory. In RADIUS, the Control Operations button is located in the Emission Statement section, at the bottom left-hand corner of the Emissions screen. This button activates the window for filling out this information.

Q3: What are SCC's and where are they reported in RADIUS?
A3: SCC's are Standard Classification Codes. These codes identify the type of source each operating scenario is. SCC's are reported in the Emission Unit/Batch Process Inventory. At least three levels of coding are required for each operating scenario (x-xx-xxx). There is an SCC builder in RADIUS that allows SCC's to be selected for each operating scenario. Please do not use the SCC's starting with "A" because these are reserved for area sources only.

Q4: I cannot revise my Emission Statement because it's locked. How do I unlock it?
A4: Select "Lock/Unlock" under the File pull-down menu in RADIUS. This will allow you to unlock the file you want.

Q5: When can I use the Autocalculate feature in RADIUS?
A5: The Autocalculate feature is only for equipment types of boiler, printing press, and surface coating equipment only. RADIUS does not calculate emissions for emergency generators, space heaters, or storage tanks.

Q6: How do I introduce a new operating scenario into the Emission Statement?
A6: Operating scenarios can be added in the Emission Unit/Batch Process Inventory.

Q7: It appears that the emissions at the facility level are not summed correctly. What should I do?
A7: Call the Emission Statement Helpline for assistance.

Q8: Should I save the RADIUS file directly to the floppy disk?
A8: No, do not save the RADIUS file directly to the floppy disk because the floppy disk may not have enough disk space. Instead, save the file onto the hard drive first and then copy it onto the floppy disk.
