Dear Mr. Dantin:

We have received an application for a Department of the Army permit dated July 15, 2013, from Entergy- Waterford 3, concerning permission to replace four dolphins on the right descending Mississippi River bank, vicinity of second order levee station 443+00, in St. Bernard Parish, Louisiana.

We have no objection to your Board's issuance of a permit for that portion of the work which is under your jurisdiction provided:

a. The work is accomplished in accordance with the above referenced application, vicinity map and accompanying drawings, copy enclosed.
b. All pile driving work is performed and completed while the stage of the Mississippi River is below elevation +15.0 feet on the Carrollton gage, at New Orleans, Louisiana. Information concerning current river stages may be obtained on our website at www.mvn.usace.army.mil.
c. Riprap is placed around all piles that penetrate through the revetment in accordance with the Corps of Engineers standard drawing, "Repair Procedures Required When Penetrating Revetments With Piles, Caissons and/or Pile Clusters," file No. H-18-45204, copy enclosed.
d. Any damage to the bank resulting from the applicant's activities is repaired at the applicant's expense.
e. That should changes in the location or section of the existing levee and/or river, or in the generally prevailing conditions in the vicinity, be required in the future in the public interest, the applicant shall make changes in the project concerned, or in the arrangement thereof, as may be necessary to satisfactorily meet the situation and shall bear the cost thereof.

This letter of no objection is based upon engineering criteria, and no interpretation or comments regarding local laws, zoning, or ordinances concerning property rights, etc., have been made. Additionally, this letter of no objection does not obviate the applicant's requirement to obtain federal, state, or local permits required by law.

If we can be of any further assistance, please feel free to call Mr. Albert Terry of my office, at (504) 862-2311. Additionally, future correspondence concerning this project should reference our permit number 13-592. This will allow us to more easily locate records of previous correspondence, and thus provide a quicker response.

Please furnish this office a copy of your permit if the applicant's proposal is approved by your Board.

Sincerely, A~1.~~
