A Letter of Permission (LOP) is a type of individual permit issued through an abbreviated processing procedure which includes coordination with Federal and state fish and wildlife agencies, and a public interest evaluation, but without the publishing of an individual public notice. The LOP cannot be used to authorize the transportation of dredged material for the purposed of dumping it in ocean waters.
LOPs may be used:
(1) In those cases subject to Section 10 of the Rivers and Harbors Act of 1899, when the Corps has determined the proposed work would be minor, would not have significant individual or cumulative impacts on environmental values, and should encounter no appreciable opposition. Examples of activities that may qualify for a Section 10 LOP include: fixed or floating small private boat docks, private piers, maintenance dredging using existing disposal sites, etc.
(2) In those cases subject to section 404 of the Clean Water Act after:
(A) The district engineer, through consultation with Federal and state fish and wildlife agencies, the Regional Administrator, Environmental Protection Agency, the state water quality certifying agency, and, if appropriate, the state Coastal Zone Management Agency, develops a list of categories of activities proposed for authorization under LOP procedures;
(B) The district engineer issues a public notice advertising the proposed list and the LOP procedures, requesting comments and offering an opportunity for public hearing; and
(C) A 401 certification has been issued or waived and, if appropriate, CZM consistency concurrence obtained or presumed either on a generic or individual basis.
Section 404 LOP:
The Sacramento District has developed LOP procedures for activities within California, Nevada, and Utah. Carefully read the procedure for your area to determine if your proposed activity qualifies for authorization under a LOP and the information required for a complete application.
