## Abstract

This document amends the Department of Veterans Affairs (VA) adjudication regulations concerning presumptive service connection for certain diseases for which there is no record during service. This amendment is necessary to implement the decision of the Secretary of Veterans Affairs that there is a positive association between exposure to herbicides used in the Republic of Vietnam during the Vietnam era and the subsequent development of chronic lymphocytic leukemia (CLL). The effect of this amendment is to establish presumptive service connection for that condition based on herbicide exposure.
