• Engineer Circular 1105-2-412: Assuring Quality of Planning Models
  This circular establishes the process and the requirements for assuring the quality of planning models. Per Planning Bulletin 2013-02 (March 2013), EC 1105-2-412 remains in effect until permanent planning model guidance is issued. The Assuring Quality of Planning Models: EC 1105-2-412 Rollout Webinar provides an overview of the EC. Note: This EC has since been modified by the Modification of the Model Certification Process and Model Approval for Use (4 December 2017) and Delegation of Model Certification (11 May 2018) memos from the Director of Civil Works.

Proposed alterations must not be injurious to the public interest or impair the usefulness of the USACE project. In November 2023, a memorandum from the USACE Director of Civil Works directed USACE to continue applying the EC until the Section 408 policy is published in the Code of Federal Regulations.
