LPA sponsors and their consultants should make sure that they are familiar with the reissued permits and conditions. Additionally, if a project was permitted under the expired permits, it must be completed before March 14, 2027. If projects will not be completed by then, LPA sponsors or their consultants need to contact the Corps of Engineers for a new permit.
