OAR 340-272-0460: Material Misstatement Assessments for Emissions Data Submitted under OAR Chapter 340, Division 215

(1) The verification team must conduct separate assessments for material misstatement of total reported emissions for each emissions data report submitted under OAR chapter 340, division 215. The assessments of material misstatement of emissions data must meet all of the requirements of this rule. (2) Material misstatement of emissions data includes any discrepancy as described in subsection (a) of this section, omission as described in subsection (b) of this section, or misreporting as described in subsection (c) of this section, or aggregation of the three, identified in the course of verification services that leads a verification team to believe that the total reported emissions (metric tons of CO2e) in a GHG Reporting Program emissions data report contains errors greater than five percent. (a) Discrepancies include any differences between the reported emissions and the verifier’s review of emissions for a data source subject to data checks under OAR 340-272-0430. (b) Omissions include any emissions the verifier concludes must be part of an emissions data report, but were not included. (c) Misreporting includes duplicate, incomplete, or other emissions the verifier concludes should or should not be part of an emissions data report. (3) Each emissions data report is subject to data checks under OAR 340-272-0430 and must be assessed separately for material misstatement of emissions data. (4) The following equation for percent error must be used to determine whether the total reported emissions in an emissions data report contain a material misstatement of emissions data and must be included in the final verification report according to OAR 340-272-0495. Percent error (emissions) = (∑(Discrepancies + Omissions + Misreporting) ÷ Total reported emissions) × 100% (5) When evaluating material misstatement, correctly substituted missing data must be deemed to be accurate, regardless of the amount of missing data.
