Standard Permits

A Letter of Permission, or LOP, is a type of standard permit that can be issued in accordance with the abbreviated procedures, as outlined in 33 CFR 325.2(e) on navigable waters of the United States.

Routine or minor work activities with minimal impacts and if objections are unlikely may qualify for a LOP.  A Letter of Permission is evaluated by both federal and state agencies and adjacent property owners for 15 days and is typically approved within 60 to 90 days.  An LOP can be issued more quickly than a standard permit because guidelines do not require an individual public notice to be issued. 

An individual permit may be issued as a standard permit or as a Letter of Permission.

A standard permit is processed through the typical review procedures, including a public notice, opportunity for a public hearing, and receipt of comments.  A standard permit is issued on a case-by-case evaluation of the proposed activities after considering all comments received.  

If work on a designated navigable water of the United States is routine or minor in scope, with minimal impacts and objections are unlikely, a LOP may be issued.
