Unit Environmental Compliance Officer Appointment Memorandum (UECO)

The Unit Environmental Compliance Officer appointment memorandum is an AR 25-50 compliant memorandum used to formally designate a Soldier or DA Civilian to serve as the unit's Unit Environmental Compliance Officer. It documents the appointee, references AGOR 200-1 (Environmental Protection and Enhancement), and is signed by the commander.

When is the UECO memo needed?

Most Army units appoint a Unit Environmental Compliance Officer (UECO) when a new commander takes charge, when the previous appointee PCSes, ETSes, or is reassigned, or when the unit's mission set changes in a way that requires renewed appointment. The memo is also required for unit inspections — including CIP, CCIR, and command climate reviews — where the AGOR 200-1 program is evaluated.

The appointment memorandum is the foundational document that establishes the appointee's authority under AGOR 200-1. Without a current, signed appointment memo on file, the unit's Unit Environmental Compliance Officer program is non-compliant — even if the appointee has all required training certificates. Inspectors will look for: a signed memo with current date, a grade that meets Full-time designee — M-Day alternate also required, and training/certification documents matching the appointee on the memo.

On EvalMe, the UECOmemo is one of 39 AR 25-50 templates that auto-cites the correct regulation, uses the proper format, and integrates with your unit's address book and signature blocks.
