ANNOUNCING: Several corrections, enhancements, and clarifications have been made to this Corps Quality Management System (QMS) procedure:
12501-SPD.01 (checklist in Word format), .02 (instructions), .03 (examples), .05 (training presentation) and .06 (checklist in Excel format): Step 2 of checklist modified and additional step added to update how ratios for preservation are determined.
12501-SPD.03 (examples): Step 2 adjustment in example 7 changed from -3 to -2 to match instructions, following calculations also corrected. Added 5 new examples for preservation. All examples converted to Excel format.
12501-SPD.06 (checklist in Excel format): corrected equation in “required mitigation” cells. Also revised “final ratio” cells to ensure the resulting ratio always has a denominator of 1, even if negative adjustments are made.
