34 8.1 Overview A single worksheet (Worksheet 8.1), denoted with a red-shaded tab in the EIAT, presents a one-page summary of the final inventory results. Worksheet 8.1 pulls data from Worksheet 7.1, but generally does not contain the inventory calculations. This is the final worksheet of the EIAT. 8.2 Inventory Results: Worksheet 8.1 Worksheet 8.1 provides a one-page summary of the lead inventory results and analysis assumptions. Although there are no required actions, there is an option to add a descriptive inventory title to the tabulated results shown. Figure 3 presents an example output of Worksheet 8.1. There are four distinct areas of report- ing in this summary as follows: 1. The âSummary of Input Option Selectionsâ lists the eight worksheets where user selection of the approach option is required and then indicates which option was incorporated into the inventory results. 2. The âOperations Summaryâ tabulates the total operations by aircraft class and the piston share of those operations based on the inventory options selected and the data provided. 3. The âPb Inventory Resultsâ contains the annual lead emissions reported for two categories: (1) aircraft class and (2) aircraft type and operation mode. Inventory results are reported in tons and grams per piston operation. In this context, âpiston operationâ is the sum of both FW and RC piston operations. 4. The final reporting element is the âOverall Pb Emission Rateâ reported on the basis of total operations (piston and non-piston operations). This metric provides a lead emission rate that can be combined with overall operations data to produce lead emissions if the conditions of the inventory development match those to which the calculations apply.
