The non-Federal interests for a navigation project for a harbor or inland harbor, or any separable element thereof, on which a contract for physical construction has not been awarded before November 17, 1986, shall pay, during the period of construction of the project, the following costs associated with general navigation features:
(A) 10 percent of the cost of construction of the portion of the project which has a depth not in excess of 20 feet; plus
(B) 25 percent of the cost of construction of the portion of the project which has a depth in excess of 20 feet but not in excess of 45 feet; plus
(C) 50 percent of the cost of construction of the portion of the project which has a depth in excess of 45 feet.
(2) Additional 10 percent payment over 30 years 
The non-Federal interests for a project to which paragraph (1) applies shall pay an additional 10 percent of the cost of the general navigation features of the project in cash over a period not to exceed 30 years, at an interest rate determined pursuant to section 2216 of this title. The value of lands, easements, rights-of-way, and relocations provided under paragraph (3) and the costs of relocations borne by the non-Federal interests under paragraph (4) shall be credited toward the payment required under this paragraph.

Except as provided under section 2283 (c) of this title, the non-Federal interests for a project to which paragraph (1) applies shall provide the lands, easements, rights-of-way, and relocations (other than utility relocations under paragraph (4)) necessary for the project, including any lands, easements, rights-of-way, and relocations (other than utility relocations accomplished under paragraph (4)) that are necessary for dredged material disposal facilities.
(4) Utility relocations 
The non-Federal interests for a project to which paragraph (1) applies shall perform or assure the performance of all relocations of utilities necessary to carry out the project, except that in the case of a project for a deep-draft harbor and in the case of a project constructed by non-Federal interests under section 2232 of this title, one-half of the cost of each such relocation shall be borne by the owner of the facility being relocated and one-half of the cost of each such relocation shall be borne by the non-Federal interests.
(5) Dredged material disposal facilities for project construction 
In this subsection, the term general navigation features includes constructed land-based and aquatic dredged material disposal facilities that are necessary for the disposal of dredged material required for project construction and for which a contract for construction has not been awarded on or before October 12, 1996.
(b) Operation and maintenance 

(1) In general 
The Federal share of the cost of operation and maintenance of each navigation project for a harbor or inland harbor constructed by the Secretary pursuant to this Act or any other law approved after November 17, 1986, shall be 100 percent, except that in the case of a deep-draft harbor, the non-Federal interests shall be responsible for an amount equal to 50 percent of the excess of the cost of the operation and maintenance of such project over the cost which the Secretary determines would be incurred for operation and maintenance of such project if such project had a depth of 45 feet.
(2) Dredged material disposal facilities 
The Federal share of the cost of constructing land-based and aquatic dredged material disposal facilities that are necessary for the disposal of dredged material required for the operation and maintenance of a project and for which a contract for construction has not been awarded on or before October 12, 1996, shall be determined in accordance with subsection (a) of this section. The Federal share of operating and maintaining such facilities shall be determined in accordance with paragraph (1).
(c) Erosion or shoaling attributable to Federal navigation works 
Costs of constructing projects or measures for the prevention or mitigation of erosion or shoaling damages attributable to Federal navigation works shall be shared in the same proportion as the cost sharing provisions applicable to the project causing such erosion or shoaling. The non-Federal interests for the project causing the erosion or shoaling shall agree to operate and maintain such measures.
(d) Non-Federal payments during construction 
The amount of any non-Federal share of the cost of any navigation project for a harbor or inland harbor shall be paid to the Secretary. Amounts required to be paid during construction shall be paid on an annual basis during the period of construction, beginning not later than one year after construction is initiated.
(e) Agreement 
Before initiation of construction of a project to which this section applies, the Secretary and the non-Federal interests shall enter into a cooperative agreement according to the provisions of section 1962d–5b of title 42. The non-Federal interests shall agree to
(1) provide to the Federal Government lands, easements, and rights-of-way, including those necessary for dredged material disposal facilities, and perform the necessary relocations required for construction, operation, and maintenance of such project;
(2) hold and save the United States free from damages due to the construction or operation and maintenance of the project, except for damages due to the fault or negligence of the United States or its contractors;
(3) provide to the Federal Government the non-Federal share of all other costs of construction of such project; and
(4) in the case of a deep-draft harbor, be responsible for the non-Federal share of operation and maintenance required by subsection (b) of this section.
(f) Consideration of funding requirements and equitable apportionment 
The Secretary shall ensure, to the extent practicable, that

(2) funds expended for such construction are apportioned equitably in accordance with regional needs; and
(3) use of a dredged material disposal facility designed, constructed, managed, or operated by a private entity is not precluded if, consistent with economic and environmental considerations, the facility is the least-cost alternative.

33 USC 2217 - Limitation on applicability of certain provisions in reports

If any provision in any report designated by this Act recommends that a State contribute in cash 5 percent of the construction costs allocated to non-vendible project purposes and 10 percent of the construction costs allocated to vendible project purposes, such provision shall not apply to the project recommended in such report.

33 USC 2218 - General applicability of cost sharing
