The Novikov-Bogoyavlensky type reduction procedure for a bi-Hamiltonian nonlinear system upon the submanifolds of crucial points for some invariant functionals, generating by local and nonlocal conservation laws, are represented. By means of the procedure a hydrodynamic Burgers equation is proven to be Hamiltonian and Lax integrable on an invariant nonlocal canonically symplectic manifold of its solutions. [References: 7]
