Section 142. Local marine facilities

(a)  The  commissioner  is  hereby
  authorized  to  enter   into   agreements   with   municipalities,   and
  municipalities  are  hereby authorized to enter into agreements with the
  commissioner, concerning the construction, operation and maintenance  of
  local marine facilities, including local marine facilities incidental to
  a harbor of refuge.
    (b)  Any such agreement shall include a provision for the construction
  of the facility, either by the municipality or by the state on behalf of
  the municipality, in accordance with plans approved by the commissioner,
  and any such agreement shall include a provision requiring operation and
  maintenance of the facility by the municipality.
    (c) In  any  such  agreement  the  state  may  agree,  within  amounts
  appropriated therefor as allocated by the director of the budget, to pay
  to  the  municipality an amount to be determined by the commissioner not
  to exceed the lesser of (1) seventy-five per cent of  the  cost  of  the
  facility, less any federal assistance received or to be received for the
  facility and (2) fifty per cent of the cost of the facility; except that
  when  the  facility  is  constructed  by  the  state  on  behalf  of the
  municipality, the municipality shall agree to reimburse the state in  an
  amount to be determined by the commissioner not to be less than the cost
  of  the  facility less the sum of (1) any federal assistance received or
  to be received for the facility and (2) the lesser of  (i)  seventy-five
  per  cent  of  the  cost  of  the  facility, less any federal assistance
  received or to be received for the facility and (ii) fifty per  cent  of
  the  cost  of the facility. Whenever two or more municipalities agree to
  participate in a project, such municipalities,  by  agreement  with  the
  commissioner  and each other, shall agree to an equitable sharing of the
  local share of the cost of the project.
    (d) In the event a municipality shall fail to pay  to  the  state  the
  municipality's  share of the cost of a facility constructed by the state
  on behalf of the municipality within six months of the certification  to
  the  municipality  by the state comptroller of the amount of such share,
  the state comptroller shall cause to be withheld from  state  assistance
  to which such municipality would otherwise be entitled, a sum sufficient
  to  reimburse  the  state for any amount remaining unpaid, together with
  interest on any such unpaid amount at the rate of  three  per  cent  per
  annum  from  the date of such certification. Monies so withheld shall be
  credited against the amount of principal and interest  payable  by  such
  municipality for its share of the cost of the facility.
