§ 2351b — Federal Breakwaters And Jetties

(a) In carrying out repair or maintenance activity of a Federal jetty, pile dike, or breakwater associated with an authorized navigation project, the Secretary shall, notwithstanding the authorized dimensions of the jetty, pile dike, or breakwater, ensure that such repair or maintenance activity is sufficient to meet the authorized purpose of such project, including ensuring that any harbor or inland harbor associated with the project is protected from projected changes in wave action or height (including changes that result from relative sea level change over the useful life of the project). (b) The Secretary may not classify any repair or maintenance activity of a Federal jetty, pile dike, or breakwater carried out under subsection (a) as major rehabilitation of such jetty, pile dike, or breakwater— (1) if the Secretary determines that— (A) projected changes in wave action or height, including changes that result from relative sea level change, will diminish the functionality of the jetty, pile dike, or breakwater to meet the authorized purpose of the project; and (B) such repair or maintenance activity is necessary to restore such functionality; or (2) if the Secretary has not carried out regular and routine Federal maintenance activity at the jetty, pile dike, or breakwater and— (A) the structural integrity of the jetty, pile dike, or breakwater is degraded as a result of a lack of such regular and routine Federal maintenance activity; or (B) the pile dike has disconnected from an authorized navigation project as a result of a lack of such regular and routine Federal maintenance activity.
