Q142. In the event fuel volume is based on third-party fuel billing meters that meet the exemption in 98.3(i)4, what are the record keeping requirements?

A142. Per §98.3(i)(4), fuel billing meters are exempted from the calibration requirements of this section, unless otherwise required by another subpart of the rule, provided that the fuel supplier and any unit combusting the fuel do not have any common owners and are not owned by subsidiaries or affiliates of the same company. The GHG Monitoring Plan should reflect the source of the data and explain why the meters meet this provision, if applicable. In circumstances where a facility depends on third party fuel billing meters per §98.3(i)(4), the facility is not required to keep maintenance and quality assurance records for these meters in accordance with §98.3(g)(5)(C) and §98.3(g)(7). However, the fuel billing records that provide data for the GHG emissions calculations must be kept, in accordance with §98.3(g)(2).
