CAMD would like to remind sources of the suggested best practices for reporting values that are rounded, as noted in Section 1.0 of the ECMPS Emissions Reporting Instructions:
"When performing calculations using any value that is reported in the XML, use the value as it is reported. In other words, use the rounded value in the calculation. However, any value that is calculated in an intermediate equation but is not reported should not be rounded before using it in a subsequent equation."
If you have any questions about this change, please contact ECMPS Support.
