List

To add a row within the body of a spreadsheet, click in any cell in the row below where you want the new row to be, then select "Row" from the "Insert" menu. You will also need to copy formulas into the new row. To do that, right-click on the row number (far left) above or below the new row and select "Copy;" right-click on the new row and select "Paste."

To hide rows you don't need, highlight those rows, right-click anywhere in the highlighted area, and select "Hide." The row numbers (far left) for the hidden rows will also be hidden. To "unhide" those rows, highlight the row numbers above and below, right-click and select "Unhide." Follow the same procedure for hiding columns.

Tips for Using & Printing Spreadsheets

To print only the spreadsheets you used, click on the tabs for those spreadsheets, while holding down the "Ctrl" button, and then select "Active sheet(s)" in the "Print what" section of the Print dialog box.

To hide spreadsheets you don't need, click on the spreadsheet tab and select "Sheet," then "Hide" from the "Format" menu. To reveal a hidden spreadsheet, select "Sheet," then "Unhide" from the "Format" menu. Spreadsheets 6a through 6c auto-populate from other spreadsheets and will display error messages if you delete the source sheets.

Credits offset debits on a one-to-one basis, regardless of REV (or cost). Applying excess credits to net debits of a higher REV is contingent on a determination by the lead federal agency that the project that produced the excess credits constitutes appropriate compensatory mitigation for the debits.
