A reformulation of reference interaction site model theory is proposed. The approach makes use of the formally correct asymptotic form of the correlations obtained from the one-center angular expansion technique. A modified closure, or equivalently, a modified propagation equation for site-site correlations is shown to incorporate the necessary information to allow dielectric consistency in finite-concentration salt solutions. Examples of the correlations and thermodynamics are given.
