Inventories are an important tool for making policy and industrial decisions, and there needs to be condence that these inventories are accurate. MII methods suggest that inventories can be veried by TD estimates that capture all emissions at a facility. Results from this study conrm this reconciliation may be possible, but indicate several nuances that must be considered when using TD estimates to verify inventories at midstream facilities. First, for the diverse set of facilities considered here, a simple comparison of TD estimates to a contemporaneous BU inventory yields the unsatisfying result that these estimates disagree, with little guidance on how to eliminate the disagreement. Therefore, measurement informed inventories will likely require both full-facility TD estimates and a battery of diagnostic measurements or monitoring on-site both to identify causes of disagreement between TD and BU estimates made in the same operating state and to capture operating states not included in the TD estimates.
